[0001] Embodiments of the present invention relate to a payment system.

Background Art

[0002] As a payment system for large retailers such as supermarkets and home centers, there is a two-person system. The two-person payment system includes an input device operated by a store clerk called a checker and a transaction processing device operated by a store clerk called a cashier. The input device is a device for inputting information related to purchased goods such as barcodes attached to the goods. The transaction processing device is a device for processing product sales data of purchased goods based on the information input via the input device and settling transactions with customers. Since the input device and the transaction processing device are separated in the two-person payment system, it is possible to start inputting information related to the purchased goods of the second customer at the input device while the transaction processing device is processing the payment of the first customer. Therefore, customers can be processed efficiently.

[0003] On the other hand, in recent years, from the viewpoints of reducing labor costs and preventing infectious diseases, there has been a demand to let customers perform operations related to receipt of payment required for transaction settlement. Even in the two-person payment system, customers are made to perform operations related to receipt of payment for the transaction processing device. By doing so, the store clerk in charge of the cashier becomes unnecessary, so labor costs can be reduced.

[0008] Hereinafter, embodiments will be described with reference to the drawings. First, the basic configuration and operation of the payment system according to the embodiment will be described with reference to FIGS. 1 to 43.

[0009] [Explanation of the Configuration of the Payment System] FIG. 1 is a block diagram showing the schematic configuration of a payment system 100 according to the embodiment. The payment system 100 includes a reservation server 10. The payment system 100 also includes an input device 20, a transaction processing device 30, a payment device 40, and an instruction device 50 for each payment lane L. The payment lane L includes a passage where customers queuing for transaction payments line up. When this payment system 100 is introduced into a retail store, consumers who purchase goods become the customers. When this payment system 100 is introduced into a paid facility such as an amusement park, an art museum, or a museum, users who use the facility become the customers. Each payment lane L is assigned, for example, a three-digit lane number as unique lane identification information.

[0010] The settlement system 100 connects a hold server 10, a transaction processing device 30 and a settlement device 40 of each settlement lane L bidirectionally communicably via a communication network 60 such as a LAN (Local Area Network). Then, for each settlement lane L, an input device 20 is connected to the transaction processing device 30 by a transmission cable 70. The settlement system 100 also connects an indicating device 50 of each settlement lane L to the communication network 60 by wire or wirelessly. However, the indicating device 50 only recognizes the communication address of the settlement device 40 of the same settlement lane L. Therefore, although the indicating device 50 can perform data communication with the settlement device 40, it cannot perform data communication with the hold server 10 and the transaction processing device 30. Also, direct data communication does not occur between the transaction processing device 30 and the settlement device 40. Details of the hold server 10, the input device 20, the transaction processing device 30, the settlement device 40 and the indicating device 50 will be described later.

[0011] Figure 2 is a schematic diagram showing the positional relationship of the input device 20, the transaction processing device 30, the settlement device 40 and the indicating device 50 provided in one settlement lane L. Figure 2 shows a settlement lane L in a retail store such as a supermarket or a home center. In this type of retail store, the sales floor where products are displayed and the checkout area called a cash register, etc. are separated. The settlement lane L is provided in the checkout area.

[0012] There is a checkout counter 80 in the checkout area. The retail store installs the checkout counter 80 along a passage PA where customers walk in the direction of the illustrated arrow. The retail store attaches the input device 20 to the top surface 81 of the checkout counter 80. Then, the upstream side of the passage PA from the input device 20 is used as a platform 82 for placing the purchased products before registration, and the downstream side is used as a platform 83 for placing the purchased products after registration.

[0013] The input device 20 includes, as an input / output device, a stationary scanner 21, a handheld scanner 22, a touch panel 23, a keyboard 24, and a display 25. The input device 20 arranges the stationary scanner 21 so as to protrude upward from the top surface 81 of the checkout counter 80, and arranges the handheld scanner 22, the touch panel 23, the keyboard 24, and the display 25 around the stationary scanner 21.

[0014] Specifically, the input device 20 fixes the stationary scanner 21 to the top surface of the checkout counter 80. The stationary scanner 21 is vertical, and the barcode reading window is located on the surface opposite to the passage PA. The input device 20 locks the handheld scanner 22 to one side of the stationary scanner 21. Also, the touch panel 23 is attached to the upper part of the stationary scanner 21 such that its operation panel surface faces the same direction as the reading window of the stationary scanner 21. Also, the keyboard 24 is attached to one side of the touch panel 23 such that its key surface faces the same direction as the operation panel surface of the touch panel 23. Further, the display 25 is attached to one side of the stationary scanner 21 such that its display screen faces the side of the passage PA. Note that the display 25 may be a touch panel.

[0015] With such an arrangement of the input / output device, an employee, i.e., a store clerk, standing in the space SP on the side opposite to the passage PA across the checkout counter 80 can operate the stationary scanner 21, the handheld scanner 22, the touch panel 23, or the keyboard 24 to input information related to transactions with customers. Information related to transactions with customers is, for example, information related to the purchased goods that the customer buys. The store clerk can confirm the product name, unit price, etc. of the purchased goods based on the information displayed on the touch panel 23. The customer can confirm the product name, unit price, etc. of the purchased goods based on the information displayed on the display 25. The input device 20 can be referred to as a scanner device or the like.

[0016] The transaction processing device 30 is a computer device that functions as a terminal of a POS (Point Of Sales) system. A retail store installs the transaction processing device 30 at the downstream end of the checkout counter 80.

[0017] The transaction processing device 30 is equipped with devices such as a keyboard 31, a first touch panel 32, a second touch panel 33, a printer 34, a coin dispenser 35, and a cashless payment terminal 36. The transaction processing device 30 arranges the keyboard 31 and the first touch panel 32 so that they can be operated by a store clerk, and arranges the second touch panel 33, the printer 34, the coin dispenser 35, and the cashless payment terminal 36 so that they can be operated by a customer.

[0018] With such an arrangement of devices, a store clerk standing in the space SP can operate the keyboard 31 or the first touch panel 32 while looking at the screen of the first touch panel 32. On the other hand, a customer standing in the passage PA can check on-site the information displayed on the second touch panel 33, for example, information related to the payment of the price. And a customer who pays the price in cash can insert cash into the coin dispenser 35 while standing in the passage PA and collect the change paid out. A customer who pays the price by cashless payment can operate the cashless payment terminal 36 while standing in the passage PA and pay the price in a cashless manner. When the payment of the price is completed, a receipt is issued from the printer 34, so the customer can receive the receipt on-site.

[0019] In this way, the transaction processing device 30 functions as a self-type settlement device that allows a customer to perform operations related to the payment of the price by himself / herself. The transaction processing device 30 can be paraphrased as a POS terminal, an electronic cash register, a sales processing device, etc.

[0020] The payment device 40 is also a self-service type payment device that allows customers to perform operations related to payment of the purchase price by themselves. The payment device 40 is used by customers who cannot pay the purchase price with the transaction processing device 30 because the transaction processing device 30 is in use, for example. For this reason, the retailer installs the payment device 40 on the downstream side of the transaction processing device 30 with respect to the moving direction of the customer indicated by the illustrated arrow. Specifically, the payment device 40 is installed along the surface on the opposite side of the surface of the transaction processing device 30 facing the customer standing in the passage PA to operate the transaction processing device 30.

[0021] The payment device 40 includes devices such as a touch panel 41, a printer 42, a coin dispenser 43, and a cashless payment terminal 44. The operation panel surface of the touch panel 41, the receipt issuing port of the printer 42, the coin insertion / payment outlet of the coin dispenser 43, and the operation unit of the cashless payment terminal 44 are all on one side of the device body. The retailer installs the payment device 40 so that one side thereof is located on the side facing the customer who has passed in front of the transaction processing device 30.

[0022] With such an installation, the customer facing the payment device 40 can confirm on the spot the information displayed on the touch panel 41, for example, information related to payment of the purchase price. And a customer who pays the purchase price in cash can insert cash into the coin dispenser 43 on the spot and collect the change paid out. A customer who pays the purchase price by cashless payment can operate the cashless payment terminal 44 on the spot to pay the purchase price in a cashless manner. When the payment of the purchase price is completed, a receipt is issued from the printer 42, so the customer can receive the receipt on the spot. The payment device 40 can be paraphrased as an accounting machine, a self-POS terminal, a payment machine, etc.

[0023] The instruction device 50 is a device that gives an instruction to call the information related to the transaction reserved in the reservation server 10 to the payment device 40. Although details will be described later, the reservation server 10 has a function of reserving the information related to the transaction with the customer by the action of the transaction processing device 30. When the instruction device 50 receives an instruction to call the information related to the transaction to the payment device 40, it gives that instruction to the reservation server 10.

[0024] As an example, the indicating device 50 uses a tablet terminal. The tablet terminal is an input device having a plate-shaped liquid crystal screen and can be operated by touching the screen with a finger, a pen, or the like. The indicating device 50 is operated by a store clerk. Therefore, the retail store installs the indicating device 50 at a position where it is easy for the store clerk in the space SP to operate. The installation position of the indicating device 50 is not particularly limited. FIG. 2 shows an example in which the indicating device 50 is installed with the screen facing the space SP on the side opposite to the surface operated by the customer of the settlement device 40.

[0034] Figure 4 is a schematic diagram showing the main storage areas formed in the main memory 302. The transaction processing device 30 designates a part of the volatile storage area in the main memory 302 as the first file area 3021, the second file area 3022, the status memory 3023, the first flag memory 3024, the second flag memory 3025, and the employee memory 3026.

[0035] The first file area 3021 is an area for storing transaction files created for each customer. The transaction file stores information related to the transaction with the customer to be processed as one transaction, for example, information related to the purchased goods. Specifically, the transaction file stores merchandise sales data including items such as product code, product name, unit price, purchase quantity, and sales amount. The product code is a unique code set for each product to identify each product. The sales amount is the amount obtained by multiplying the unit price by the purchase quantity. The merchandise sales data only needs to include at least the product code and the purchase quantity of the purchased goods.

[0036] The second file area 3022 is an area for temporarily storing the transaction files of customers who make payments using the transaction processing device 30. The second file area 3022 stores the transaction files stored in the first file area 3021 or the transaction files held by the holding server 10.

[0037] The status memory 3023 is an area for storing the payment status ST. The payment status ST is identification information representing the state regarding payment. The states regarding payment include a first state in which the payment method is not specified by the input device 20 and a second state in which the payment method is specified by the input device 20. In the present embodiment, the payment status ST representing the first state is set to "10", and the payment status ST representing the second state is set to "20".

[0038] The first flag memory 3024 is an area for storing the payment-in-progress flag Fa. The payment-in-progress flag Fa is 1-bit data for identifying whether payment is in progress in the transaction processing device 30.

[0040] The employee memory 3026 is an area for storing employee codes. The employee code is a unique code assigned to each store employee who is a staff member of the store. The employee code functions as operator identification information for identifying the store employee who is the operator of the input device 20. The employee memory 3026 stores the employee code of the store employee who has signed on to the transaction processing device 30. Signing on means authenticating the operator of the input device 20 and making the input device 20 and the transaction processing device 30 available for use. A store employee standing at the space SP first signs on by entering their own employee code and password. When the employee code and password are authenticated and the sign-on is successful, the employee code is stored in the employee memory 3026. Thus, the input device 20 and the transaction processing device 30 become available for use.

[0041] Incidentally, an employee who has finished using the system signs off. Signing off means returning the input device 20 and the transaction processing device 30 to a state where they cannot be used. By signing off, the employee code in the employee memory 3026 is cleared. Also, the input device 20 and the transaction processing device 30 become unavailable for use. Sign-on can be rephrased as logging in, signing in, etc. Sign-off can be rephrased as logging out, signing out, etc. The employee code can be rephrased as a store employee code, employee ID, store employee ID, etc.

[0100] [Operation Explanation of the Payment System] Next, the main operations of the payment system 100 will be described using the flowcharts of FIGS. 11 to 20 and the screen examples of FIGS. 21 to 43. Note that the content and procedure of the operations described using the flowcharts are examples. The content and procedure can be appropriately changed as long as the same effects can be achieved. Also, the screen examples are examples. The content of the output text, the arrangement of images, the types and layouts of software keys, etc. can be appropriately changed.

[0101] FIGS. 11 to 14 are flowcharts showing the main procedure of the first information processing executed by the processor 301 of the transaction processing device 30 according to the first business program. A customer who has collected purchased goods by walking around the store moves to the cashier area. Then the customer places the purchased goods on the counter 82 of the checkout counter 80 in the available aisle PA. The store clerk standing in the space SP gives a command to start registration when the customer comes to the cashier area. For example, the store clerk touches the start button displayed on the touch panel 23. This operation serves as a command to start registration. Upon receiving this command, the processor 301 starts the first information processing. The processor 301 sets the screens of the touch panel 23 and the display 25 in the input device 20 as the registration screen as ACT101.

[0102] Figure 21 shows an example of a registration screen SAa displayed on the touch panel 23. The registration screen SAa is divided into a current area AAa, a details area AAb, and a total area AAc. The current area AAa is an area for displaying the product name, purchase quantity, and selling amount of the latest purchased product. The details area AAb is an area for listing the product name, purchase quantity, unit price, discount amount, and selling amount of the purchased product in a series of transactions in numerical order. The total area AAc is an area for displaying the total purchase quantity and the total selling amount of the purchased product in a single transaction. The registration screen SAa includes a subtotal button BAa. The subtotal button BAa is a software key. The subtotal button BAa is an operator for instructing the subtotal output of the purchased product registered as a single transaction.

[0103] Figure 22 shows an example of a registration screen SBa displayed on the display 25. The registration screen SBa divides the screen into a plurality of rows (seven rows in the example of Figure 22), and the rows from the first row to one row before the last row are the rows of the details area ABa, and the last row is the row of the total area ABb. In the rows of the details area ABa, the product name, unit price, purchase quantity, and selling amount of the purchased product are displayed one by one. In the total area ABb, the total purchase quantity and the total selling amount are displayed in one row.

[0104] The store clerk who has confirmed the registration screen SAa performs the registration of the purchased product placed at the checkout counter 80. That is, the store clerk scans the barcode attached to the purchased product with the stationary scanner 21 or the handheld scanner 22 of the input device 20. By scanning the barcode, the product code of the purchased product is input into the transaction processing device 30 via the input device interface 310. If the purchased product is not attached with a barcode, the store clerk displays a list of products without barcodes on the touch panel 23 of the input device 20. Then the store clerk selects the purchased product from the list. By such an operation, the product code of the purchased product without a barcode is input into the transaction processing device 30 via the input device interface 310.

[0105] The processor 301 that sets the screens of the touch panel 23 and the display 25 as the registration screen SAa and the registration screen SBa proceeds to ACT102. The processor 301 waits for the registration of the purchased product as ACT102. When a product code is input from the input device 20 via the input device interface 310, the processor 301 determines that there is registration of the purchased product. The processor 301 proceeds from ACT102 to ACT103. The processor 301 creates a transaction file in the first file area 3021 as ACT103. Hereinafter, the transaction file generated in ACT103 is referred to as the first transaction file.

[0106] The processor 301 that created the first transaction file proceeds to ACT104. The processor 301 processes the product sales data as ACT104. This processing is to read the product name, unit price, etc. of the product specified by the input product code from the product master and generate product sales data of the purchased product including the product code, product name, unit price, purchase quantity, sales amount, etc. The processor 301 that generated the product sales data of the purchased product proceeds to ACT105. The processor 301 stores the product sales data of the purchased product in the first transaction file as ACT105. Also, the processor 301 updates the registration screen SAa and the registration screen SBa as ACT106.

[0107] Regarding the registration screen SAa, the processor 301 displays the product name, purchase quantity, and sales amount of the product sales data stored in the first transaction file in the current area AAa. At this time, if the product sales data of the previously registered purchased product was displayed in the current area AAa, the processor 301 displays the product name, purchase quantity, unit price, discount amount, and sales amount of the product sales data in the details area AAb. Also, the processor 301 displays the total of the purchase quantity and sales amount of all the product sales data stored in the first transaction file in the total area AAc.

[0108] Regarding the registration screen SBa, the processor 301 displays the product name, unit price, purchase quantity, and sales amount of the product sales data stored in the first transaction file on the first line of the details area ABa. At this time, if the product sales data is already displayed on the first line of the details area ABa, the processor 301 sequentially shifts the data from the second line onwards to the lines below the second line, and then displays the product sales data stored in the first transaction file on the first line. Also, the processor 301 displays the total of the purchase quantity and sales amount of all the product sales data stored in the first transaction file in the total area ABb.

[0109] The processor 301 that has updated the registration screen SAa and the registration screen SBa proceeds to ACT107. As ACT107, the processor 301 checks whether the next purchased product has been registered. If the next purchased product has not been registered, the processor 301 proceeds to ACT108. As ACT108, the processor 301 checks whether the subtotal button BAa has been input. If the subtotal button BAa has not been input, the processor 301 returns to ACT107. In this way, the processor 301 waits in ACT107 and ACT108 for the next purchased product to be registered or the subtotal button BAa to be input.

[0110] In the waiting state of ACT107 and ACT108, when a purchased product is registered, the processor 301 returns to ACT104. Then the processor 301 executes the processing from ACT104 to ACT106 in the same manner as described above. Thus, each time the store clerk operates the stationary scanner 21, the handheld scanner 22, or the touch panel 23 of the input device 20 to input the data of the purchased products placed on the checkout counter 80 one by one, the processor 301 generates the product sales data of the purchased product based on the information related to the purchased product, that is, the product code, and stores it in the first transaction file. Also, the processor 301 updates the registration screen SAa and the registration screen SBa. After finishing the registration of the purchased products in this way, the store clerk touches the subtotal button BAa.

[0111] In the standby states of ACT107 and ACT108, when the subtotal button BAa is input by a touch operation, the processor 301 proceeds to ACT109. The processor 301 sets the screens of the touch panel 23 and the display 25 in the input device 20 as the subtotal screen in ACT109.

[0112] FIG. 23 is an example of the subtotal screen SAb displayed on the touch panel 23. The subtotal screen SAb includes a total area AAd where the total of the purchase quantities of the purchased goods and the total sales amount in one transaction are displayed. The subtotal screen SAb also includes a subtotal discount button BAb, a subtotal percentage discount button BAc, a payment method selection button BAd, a payment button BAe, and a return button BAf. Each of the buttons BAb, BAc, BAe, BAf is a software key. The subtotal discount button BAb is an operator for instructing a discount on the total amount. The subtotal percentage discount button BAc is an operator for instructing a percentage discount on the total amount. Incidentally, when the subtotal discount button BAb is input and the discount amount is input using the numeric keys on the keyboard 24, the total amount is discounted. Similarly, when the subtotal percentage discount button BAc is input and the discount rate is input using the numeric keys on the keyboard 24, the total amount is discounted.

[0113] The payment method selection button BAd is an operator for instructing the selection of a payment method. The payment button BAe is an operator for instructing the transition to payment after registering the purchased goods. The return button BAf is an operator for instructing a return to the registration of the purchased goods.

[0114] FIG. 24 is an example of the subtotal screen SBb displayed on the display 25. The subtotal screen SBb includes an area ABc where information regarding the payment of the price is displayed. In the area ABc, the total quantity and total amount of the purchased goods, the deposit amount, and the balance are displayed. At this point, since no deposit amount has occurred, the deposit amount is 0 yen, and the balance is the amount obtained by subtracting the deposit amount from the total amount.

[0115] The store clerk who has confirmed the subtotal screen SAb checks whether there are any unregistered purchased items remaining at the checkout counter 80. If there are unregistered purchased items, the store clerk touches the return button BAf. If there are no unregistered purchased items, the store clerk decides whether to confirm the payment method with the customer. For example, during peak store hours, the store clerk confirms the payment method with the customer, and during off-peak hours, the store clerk does not confirm the payment method with the customer. If the store clerk is to confirm the payment method with the customer, the store clerk touches the payment method selection button BAd. If the store clerk is not to confirm the payment method with the customer, the store clerk touches the payment button BAe.

[0116] The processor 301, which sets the screen of the touch panel 23 as the subtotal screen SAb and the screen of the display 25 as the subtotal screen SBb, proceeds to ACT110. The processor 301 checks whether the return button BAf has been input as ACT110. If the return button BAf has not been input, the processor 301 proceeds to ACT111. The processor 301 checks whether the payment method selection button BAd has been input as ACT111. If the payment method selection button BAd has not been input, the processor 301 proceeds to ACT112. The processor 301 checks whether the payment button BAe has been input as ACT112. If the payment button BAe has not been input, the processor 301 returns to ACT110. In this way, the processor 301 that has displayed the subtotal screen SAb waits for the return button BAf, the payment method selection button BAd, or the payment button BAe to be input in ACT110 to ACT112.

[0117] In the standby states of ACT110 to ACT112, when the return button BAf is input by a touch operation, the processor 301 proceeds to ACT113. The processor 301, as ACT113, returns the screens of the touch panel 23 and the display 25 to the immediately preceding registration screens SAa and SBa. Then the processor 301 enters the standby states of ACT107 and ACT108. Thus, the store clerk can operate the stationary scanner 21, the handy scanner 22, or the touch panel 23 of the input device 20 to input data of unregistered purchased items.

[0118] In the standby states of ACT110 to ACT112, when the payment method selection button BAd is input by a touch operation, the processor 301 proceeds to ACT121 in FIG. 12. The processor 301, as ACT121, sets the screen of the touch panel 23 as the payment method selection screen SAc (see FIG. 25). The screen of the display 25 remains the subtotal screen SBb.

[0119] FIG. 25 is an example of the payment method selection screen SAc displayed on the touch panel 23. The payment method selection screen SAc includes a total area AAd similar to the subtotal screen SAb. The payment method selection screen SAc also includes a selection button group BAg for each payment method. The selection button group BAg includes a cash button, a credit button, an electronic money button, a code settlement button, and a gift certificate button.

[0120] The cash button is a button for instructing cash payment. The credit button is a button for instructing credit card payment. The electronic money button is a button for instructing electronic money payment. The code settlement button is a button for instructing code settlement payment. The gift certificate button is a button for instructing payment with a gift certificate. When the gift certificate button is input, a screen for selecting the type of gift certificate such as a merchandise voucher is displayed. The cash button, the credit button, the electronic money button, the code settlement button, and the gift certificate button are all software keys.

[0121] The store clerk who has confirmed the payment method selection screen SAc checks the payment method with the customer. Then the store clerk touches the button of the payment method selected by the customer. For example, if the customer wishes to pay in cash, the store clerk touches the cash button in the selection button group BAg. For example, if the customer wishes to pay with a credit card, the store clerk touches the credit button in the selection button group BAg. Similarly, when the customer wishes to pay with electronic money or code settlement, the store clerk also touches the corresponding button in the selection button group BAg.

[0122] The processor 301 that has set the screen of the touch panel 23 as the payment method selection screen SAc proceeds to ACT122. The processor 301 waits for a payment method to be selected as ACT122. When any payment method is selected by a touch operation on the selection button group BAg, the processor 301 proceeds to ACT123. The processor 301 obtains the payment code of the selected payment method as ACT123. In this embodiment, unique payment codes are set in advance for each payment method such as cash payment, credit card payment, electronic money payment, code settlement payment, etc. For example, when the cash button is touched, the processor 301 obtains the payment code corresponding to cash payment, for example, "11". For example, when the credit button is touched, the processor 301 obtains the payment code corresponding to credit card payment, for example, "22". The same applies when other electronic money buttons and code settlement buttons are touched.

[0123] The processor 301 that has obtained the payment code proceeds to ACT124. The processor 301 sets the screen of the touch panel 23 as the payment screen SAd (see FIG. 26) as ACT124. The screen of the display 25 remains the subtotal screen SBb.

[0124] FIG. 26 shows an example of a payment screen SAd when cash payment is selected as the payment method. The payment screen SAd includes a total area AAd similar to the subtotal screen SAb and the payment method selection screen SAc. The payment screen SAd also includes a payment button BAh. The payment button BAh is an operator for instructing the transition to payment of the price. The payment button BAh is a software key. The store clerk who has confirmed the payment screen SAd touches the payment button BAh.

[0125] The processor 301 with the screen of the touch panel 23 as the payment screen SAd proceeds to ACT125. The processor 301 waits for the payment button BAh to be input as ACT125. When the payment button BAh is input by a touch operation, the processor 301 proceeds to ACT126.

[0126] On the other hand, in the waiting state of ACT110 to ACT112 in FIG. 11, when the payment button BAe is input by a touch operation, the processor 301 proceeds to ACT126 in FIG. 12. Thus, when the payment button BAe on the subtotal screen SAb or the payment button BAh on the payment screen SAd is input, the processor 301 proceeds to ACT126.

[0127] The processor 301 checks the payment in progress flag Fa as ACT126. In a state where the price has not been paid in the transaction processing device 30, the payment in progress flag Fa is "0". When the payment in progress flag Fa is "0", the processor 301 proceeds to ACT131 in FIG. 13. The processing after ACT131 will be described later.

[0128] In ACT126, when the payment flag Fa is "1", that is, when the payment for the price is being made in the transaction processing device 30, the processor 301 proceeds to ACT127. The processor 301 checks the pending flag Fb as ACT127. If the information related to the transaction of the previous customer who settled in the same settlement lane L is not pending in the pending server 10, the pending flag Fb is "0". When the pending flag Fb is "0", the processor 301 proceeds to ACT141 in FIG. 14. The processing after ACT141 will also be described later.

[0129] In ACT127, when the pending flag Fb is "1", that is, when the information related to the transaction of the previous customer who settled in the same settlement lane L is pending in the pending server 10, the processor 301 proceeds to ACT128. The processor 301 displays a pop-up PUa (see FIG. 27) on the subtotal screen SAb or the payment screen SAd of the touch panel 23 to notify that the payment for the price is impossible. Also, the processor 301 displays a text TXa (see FIG. 28) on the subtotal screen SBb of the display 25 to instruct to wait because the payment for the price is impossible.

[0130] FIG. 27 is an example of the pop-up PUa displayed on the payment screen SAd of the touch panel 23. The store clerk who confirms the pop-up PUa will wait until the previous customer finishes paying the price.

[0131] FIG. 28 is an example of the text TXa displayed on the subtotal screen SBb of the display 25. The customer who confirms the text TXa will wait until the payment for the price becomes possible.

[0132] The processor 301, which has notified that payment cannot be made using the touch panel 23 and the display 25, returns to ACT125. The processor 301 waits for the payment button BAe or the payment button BAh to be input again. When the payment button BAe or the payment button BAh is input, the processor 301 proceeds to ACT126. Then the processor 301 executes the processing after ACT126 in the same manner as described above. Therefore, if the payment-in-progress flag Fa has been rewritten to "0", the processor 301 proceeds to ACT131 in FIG. 13. If the payment-in-progress flag Fa remains "1" but the pending flag Fb has been rewritten to "0", the processor 301 proceeds to ACT141 in FIG. 14.

[0133] On the other hand, if the payment-in-progress flag Fa and the pending flag Fb still remain "1", the processor 301 proceeds to ACT128. Therefore, the pop-up PUa continues to be displayed on the subtotal screen SAb or the payment screen SAd of the touch panel 23, and the text TXa continues to be displayed on the subtotal screen SBb of the display 25.

[0134] When the payment-in-progress flag Fa is "0", that is, when payment is not being made in the transaction processing device 30, and the payment button BAe on the subtotal screen SAb of the touch panel 23 or the payment button BAh on the payment screen SAd is input, the processor 301 proceeds to ACT131 in FIG. 13. As ACT131, the processor 301 displays a pop-up PUb (see FIG. 29) on the subtotal screen SAb or the payment screen SAd of the touch panel 23 to notify that payment can be made by the transaction processing device 30. The processor 301 also displays a text TXb (see FIG. 30) on the subtotal screen SBb of the display 25 to indicate that payment can be made.

[0135] FIG. 29 is an example of a pop-up PUb displayed on the payment screen SAd of the touch panel 23. Since a store clerk who has confirmed the pop-up PUb can know that payment of the price is possible with the transaction processing device 30, the clerk will guide the customer to the side where the transaction processing device 30 is installed.

[0136] FIG. 30 is an example of text TXb displayed on the subtotal screen SBb of the display 25. A customer who has confirmed the text TXb will move to the side where the transaction processing device 30 is installed according to the guidance of the store clerk and make the payment of the price.

[0137] The processor 301 that has notified that payment of the price is possible using the touch panel 23 and the display 25 proceeds to ACT132. The processor 301 checks whether or not it has acquired a payment code as ACT132. If it has not acquired the payment code, the processor 301 proceeds to ACT133. The processor 301 sets the payment status ST stored in the status memory 3023 to "10" as ACT133. On the other hand, if the payment code has been acquired in the process of ACT123, the processor 301 proceeds to ACT134. The processor 301 stores the payment code in the first transaction file as ACT134. Further, the processor 301 sets the payment status ST stored in the status memory 3023 to "20" as ACT135.

[0138] When the processing of ACT133 or ACT135 is completed, the processor 301 proceeds to ACT136. The processor 301 selects, as ACT136, the first transaction file stored in the first file area 3021. Then, the processor 301 saves, as ACT137, the first transaction file in the second file area 3022. After that, the processor 301 rewrites, as ACT138, the payment-in progress flag Fa in the first flag memory 3024 to "1". Also, the processor 301 clears, as ACT139, the first file area 3021. With the above, the processor 301 finishes the first information processing. Hereinafter, the transaction file saved in the second file area 3022 is referred to as the second transaction file.

[0139] On the other hand, when the payment-in progress flag Fa is "1" but the pending flag Fb is "0", and the payment button BAe on the subtotal screen SAb or the payment button BAh on the payment screen SAd is input, the processor 301 proceeds to ACT141 in FIG. 14. The processor 301 checks, as ACT141, whether a payment code has been acquired. If the payment code has not been acquired, the processor 301 proceeds to ACT142. The processor 301 sets, as ACT142, the payment status ST stored in the status memory 3023 to "10". On the contrary, if the payment code has been acquired in the processing of ACT123, the processor 301 proceeds to ACT143. The processor 301 stores, as ACT143, the payment code in the first transaction file. Also, the processor 301 sets, as ACT144, the payment status ST stored in the status memory 3023 to "20".

[0140] When the processing of ACT142 or ACT144 is completed, the processor 301 proceeds to ACT145. The processor 301 transmits, as ACT145, a pending event to the pending server 10 via the communication interface 305. The pending event is an event requesting the pendency of the transaction file. The pending event includes the transaction processor ID of the transaction processor 30.

[0141] As will be described later, since a permission response is returned from the hold server 10 that has received the hold event, the processor 301 waits for the permission response as ACT146. Then, when the permission response is received via the communication interface 305, the processor 301 proceeds to ACT147. The processor 301 acquires the employee code from the employee memory 3026 as ACT147. Then, the processor 301 outputs the first transaction file to the hold server 10 together with the employee code as ACT148.

[0142] After that, the processor 301 sets the hold flag Fb to "1" as ACT149. Also, the processor 301 clears the first file area 3021 as ACT150. Thus, the processor 301 ends the first information processing.

[0143] As described with reference to FIG. 13, when the payment button BAe or the payment screen SAd is input and the payment flag Fa is "0", that is, when there is no customer paying the price in the transaction processing device 30, it is notified that the price payment in the transaction processing device 30 is possible. Also, the first transaction file is saved in the second file area 3022, and the payment flag Fa becomes "1". Therefore, self-service price payment by the customer is possible in the transaction processing device 30. The customer moves to the installation location of the transaction processing device 30 and performs an operation for price payment.

[0144] On the other hand, as described with reference to FIG. 14, when the payment button BAe or the payment screen SAd is input and the payment flag Fa is "1", that is, when there is a customer paying the price in the transaction processing device 30, the first transaction file is output to the hold server 10. Also, the hold flag Fb becomes "1", and the first file area 3021 is cleared. At this point, it is not determined whether the customer pays the price using the transaction processing device 30 or the settlement device 40.

[0145] Incidentally, as described with reference to FIGS. 13 and 14, when the first information processing ends, the first file area 3021 is cleared. Therefore, the processor 301 of the transaction processing device 30 can continue to start the first information processing. That is, when the next customer comes to the accounting area and the clerk gives an instruction to start registration, the processor 301 executes the first information processing after ACT101 in the same manner as described above. Therefore, the screen of the touch panel 23 becomes the registration screen SAa.

[0146] Here, the processor 301 realizes the function as input information acquisition means 3011 (first input information acquisition means) for acquiring information related to purchased goods received by the input means 2011 from the input device 20 by executing the processes of ACT102 and ACT106 via the input device interface 310. Further, the processor 301 realizes the function as input information acquisition means 3011 (second input information acquisition means) for acquiring a signal of an input end instruction received by the end reception means 2012 from the input device 20 by executing the processes of ACT112 and ACT125 via the input device interface 310. Furthermore, the processor 301 realizes the function as input information acquisition means 3011 (third input information acquisition means) for acquiring information on the payment method received by the first payment reception means 2013 from the input device 20 by executing the processes of ACT121 to ACT123 via the input device interface 310.

[0147] The processor 301 realizes the function as the first amount output means 3012 by executing the processes of ACT109 and ACT124 in cooperation with the touch panel 23 and the display 25. The processor 301 realizes the function as the transaction information output means 3016 by executing the processes of ACT145 to ACT148 in cooperation with the communication interface 305. The processor 301 realizes the function as the operator acquisition means 3015 by executing the process of ACT147 in cooperation with the employee memory 3026.

[0148] FIG. 15 is a flowchart showing the main procedure of a second information process executed by the processor 301 of the transaction processing apparatus 30 according to the first business program. The processor 301 executes the second information process in parallel with the first information process described above.

[0149] The processor 301 waits for the payment-in-progress flag Fa to become "1" as ACT161. In ACT138 of the first information process, when the payment-in-progress flag Fa becomes "1", the processor 301 proceeds to ACT162. The processor 301 checks the payment status ST as ACT162. When the payment status ST is "10", that is, when the payment method for the price is not selected in the first information process, the processor 301 proceeds to ACT163. The processor 301 sets the screen of the second touch panel 33 as the payment method selection screen SCa (see FIG. 31) as ACT163.

[0150] FIG. 31 is an example of the payment method selection screen SCa displayed on the second touch panel 33. The payment method selection screen SCa includes a selection button group BCa for each payment method. The selection button group BCa includes a cash button, a credit button, an electronic money button, and a code settlement button. The payment method selection screen SCa also includes a total area ACa in which the total purchase quantity and the total sales amount of the purchased goods in one transaction are displayed. In the total area ACa, the total purchase quantity and the total sales amount calculated based on the product sales data of the purchased goods stored in the second transaction file are displayed.

[0151] The customer who has confirmed the payment method selection screen SCa touches the button for the desired payment method. For example, a customer who wishes to pay in cash touches the cash button in the selection button group BCa. For example, a customer who wishes to pay with a credit card touches the credit button in the selection button group BCa. For example, a customer who wishes to pay with electronic money touches the electronic money button in the selection button group BCa. For example, a customer who wishes to pay by code settlement touches the code settlement button in the selection button group BCa.

[0152] The processor 301 that sets the screen of the second touch panel 33 as the payment method selection screen SCa proceeds to ACT164. The processor 301 waits for a payment method to be selected as ACT164. When any payment method is selected by a touch operation on the selection button group BCa, the processor 301 proceeds to ACT165. As ACT165, the processor 301 obtains the payment code of the selected payment method in the same manner as the processing of ACT123 of the first information processing.

[0153] On the other hand, when the payment status ST is "20" in ACT162, that is, when the payment method for the price has been selected in the first information processing, the processor 301 proceeds to ACT166. As ACT166, the processor 301 extracts the payment code from the second transaction file.

[0154] The processor 301 that has completed the processing of ACT165 or ACT166 proceeds to ACT167. As ACT167, the processor 301 sets the screen of the second touch panel 33 as the payment notification screen SCb (see FIG. 32). The payment notification screen SCb is a screen based on the payment code obtained by the processing of ACT165 or ACT166.

[0155] FIG. 32 is an example of the payment notification screen SCb displayed on the second touch panel 33. FIG. 32 shows the payment notification screen SCb when the payment code for cash payment is obtained by the processing of ACT165 or ACT166. The payment notification screen SCb includes the change machine information area ACb. In the change machine information area ACb, the total amount, the total amount of cash inserted into the automatic change machine 35, so-called the inserted amount, and the balance obtained by subtracting the inserted amount from the total amount are displayed.

[0156] Customers who have confirmed the payment notification screen SCb pay the amount using the payment method they have selected. For example, a customer who has selected cash payment inserts cash into the automatic change dispenser 35. A customer who has selected credit card payment has the credit card data read by the reader of the cashless payment terminal 36. A customer who has selected electronic money payment has the data of the electronic money medium read by the reader of the cashless payment terminal 36. A customer who has selected code settlement payment has the barcode or two-dimensional data code for code settlement read by the scanner of the cashless payment terminal 36.

[0157] The processor 301 that has set the screen of the second touch panel 33 as the payment notification screen SCb proceeds to ACT168. The processor 301 waits for the start of the payment of the amount as ACT168. For example, when cash payment is selected, the processor 301 waits for cash to be inserted into the automatic change dispenser 35. For example, when credit card payment is selected, the processor 301 waits for the credit card data to be read at the cashless payment terminal 36. For example, when electronic money payment is selected, the processor 301 waits for the electronic money data to be read at the cashless payment terminal 36. For example, when code settlement payment is selected, the processor 301 waits for the barcode or two-dimensional data code for code settlement to be read at the cashless payment terminal 36.

[0158] When the payment of the amount starts, the processor 301 proceeds to ACT169. The processor 301 assigns a transaction number as ACT169. The transaction number is, for example, a 7-digit number obtained by attaching a 4-digit serial number to a 3-digit transaction processing device ID. The serial number is incremented by "1" each time a transaction is settled at the transaction processing device 30. The processor 301 that has assigned the transaction number proceeds to ACT170. The processor 301 sets the screen of the second touch panel 33 as the payment in progress screen SCc (see FIG. 33) as ACT170.

[0159] FIG. 33 shows an example of a payment-in progress screen SCc displayed on the second touch panel 33. FIG. 33 shows the payment-in progress screen SCc when a payment code for cash payment is obtained by the process of ACT165 or ACT166. The payment-in progress screen SCc has the same layout as the payment notification screen SCb. In the payment-in progress screen SCc, the information displayed in the change machine information area ACb is updated according to the amount of cash inserted into the automatic change machine 35. The payment-in progress screen SCc further includes a settlement button BCb. The settlement button BCb is a software key. The settlement button BCb is an operator for instructing the end of the payment of the price. A customer who has finished paying the price by the selected payment method touches the settlement button BCb.

[0160] The processor 301 with the screen of the second touch panel 33 as the payment-in progress screen SCc proceeds to ACT171. The processor 301 waits for the settlement button BCb to be input as ACT171. When the settlement button BCb is input by a touch operation, the processor 301 proceeds to ACT172. The processor 301 executes a settlement process for the transaction based on the payment code as ACT172. That is, when the payment code is a cash payment code, the processor 301 executes a settlement process for the transaction with the cash inserted into the automatic change machine 35. When the payment code is a credit card payment code, the processor 301 executes a settlement process for the transaction with the credit card data read by the cashless settlement terminal 36. When the payment code is an electronic money payment code, the processor 301 executes a settlement process for the transaction with the electronic money data read by the cashless settlement terminal 36. When the payment code is a code settlement payment code, the processor 301 executes a settlement process for the transaction with the barcode or two-dimensional data code read by the cashless settlement terminal 36. Since these settlement processes are all well-known, detailed descriptions are omitted.

[0161] After finishing the settlement process, the processor 301 proceeds to ACT173. The processor 301 drives the printer 34 as ACT173 to issue a receipt. Also, the processor 301 sets the screen of the second touch panel 33 as the payment completion screen SCd (see FIG. 34) as ACT174. The receipt is a sheet that records details such as the name, price, quantity, and amount of the purchased goods. The transaction date, time, transaction number, etc. are also recorded on the receipt.

[0162] FIG. 34 is an example of the payment completion screen SCd displayed on the second touch panel 33. FIG. 34 shows the payment completion screen SCd when the payment code for cash payment is obtained by the process of ACT165 or ACT166. The payment completion screen SCd includes a change machine information area ACb similar to the payment notification screen SCb and the payment in progress screen SCc. A customer who has confirmed the payment completion screen SCd will take the receipt and the change and leave the store.

[0163] The processor 301 that has displayed the payment completion screen SCd proceeds to ACT175. The processor 301 saves the data of the second transaction file, that is, the data of the goods purchased by the customer who has completed the settlement, as ACT175. The storage destination of the data is, for example, the auxiliary storage device 303. The storage destination of the data may be the main memory 302. Alternatively, the second transaction file may be transmitted to the POS server via the communication interface 305 and stored by the POS server. It may be stored in the hold server 10 instead of the POS server.

[0164] The processor 301 that has saved the data of the second transaction file proceeds to ACT176. The processor 301 clears the second file area 3022 as ACT176. Also, the processor 301 rewrites the payment in progress flag Fa to "0" as ACT177. Thus, the processor 301 ends the second information processing.

[0165] Here, the processor 301 realizes the function as the first amount output means 3012 by executing the processing of ACT167 in cooperation with the second touch panel 33. The processor 301 realizes the function as the second payment reception means 3013 by executing the processing of ACT163 to ACT165 in cooperation with the second touch panel 33. The processor 301 realizes the function as the first settlement means 3014 by executing the processing of ACT172.

[0166] In this way, when the payment in progress flag Fa is "0" and the payment button BAe on the subtotal screen SAb or the payment button BAh on the payment screen SAd is input, and the payment in progress flag Fa becomes "1", the processor 301 executes the processing of ACT162 to ACT177. By the operation of the transaction processing device 30 based on this processing, the customer can settle the transaction by operating the transaction processing device 30 by himself / herself to pay the price.

[0167] FIG. 16 is a flowchart showing the main procedure of the third information processing executed by the processor 301 of the transaction processing device 30 according to the first business program. The processor 301 also executes the third information processing in parallel with the above-described first information processing.

[0168] The processor 301 waits for the pending flag Fb to become "1" as ACT181. In ACT149 of the first information processing, when the pending flag Fb becomes "1", the processor 301 proceeds to ACT182. The processor 301 sets the screen of the first touch panel 32 as the guidance screen SDa (see FIG. 35) as ACT182.

[0169] FIG. 35 is an example of a guidance screen SDa displayed on the first touch panel 32. The guidance screen SDa displays a pop-up PUc that shows guidance when guiding a customer to the payment device 40 and guidance when setting the transaction processing device 30 as the payment destination, and also displays a hold cancellation button BDa. The hold cancellation button BDa is a second operator that instructs the hold server 10 to cancel the hold of the transaction file and transmit the transaction file to the transaction processing device 30.

[0170] The store clerk who has confirmed the guidance screen SDa determines the payment destination of the customer whose transaction file is on hold in the hold server 10. For example, if another customer is making a payment with the transaction processing device 30 but there is no customer making a payment with the payment device 40, the store clerk determines the payment device 40 as the payment destination. For example, if another customer is still making a payment with the payment device 40 but the customer who made a payment with the transaction processing device 30 has finished paying, the store clerk determines the transaction processing device 30 as the payment destination.

[0171] Here, in order to clarify the operation of the store clerk determined as the payment destination, the description of FIG. 16 is temporarily interrupted, and the information processing executed by the processor 101 of the hold server 10 will be described first using FIGS. 17 and 18.

[0172] FIGS. 17 and 18 are flowcharts showing the main procedure of the fourth information processing executed by the processor 101 of the hold server 10 according to the second business program. The processor 101 is waiting for a hold event as ACT201. When receiving a hold event via the communication interface 105, the processor 101 proceeds to ACT202. The processor 101 returns a permission response as ACT202. That is, the processor 101 returns a permission response to the transaction processing device 30 specified by the transaction processing device ID included in the hold event.

[0173] As described with reference to FIG. 14, when the processor 301 of the transaction processing apparatus 30 that has transmitted the hold event receives the permission response, it outputs the transaction file (first transaction file) stored in the first file area to the hold server 10 together with the employee code, which is the operator identification information. Therefore, the processor 101 that has returned the permission response waits for the transaction file as ACT203. When the transaction file is received via the communication interface 105, the processor 101 proceeds to ACT204. The processor 101 acquires the transaction processing apparatus ID set for the transaction processing apparatus 30 that is the data transmission source as ACT204. The transaction processing apparatus ID is included in the hold event.

[0174] The processor 101 that has detected the transaction processing apparatus ID proceeds to ACT205. The processor 101 acquires the employee code received together with the transaction file as ACT205. Then, the processor 101 stores the employee code in the lane table 1032 as ACT206. That is, the processor 101 describes the employee code acquired in the process of ACT205 in column Ce of the lane table 1032 in the same row as the transaction processing apparatus ID acquired in the process of ACT204.

[0175] The processor 101 that has stored the employee code proceeds to ACT207. The processor 101 saves the transaction file received from the transaction processing apparatus 30 in the employee-specific folder 1033 identified by the employee code acquired as ACT207. Also, the processor 101 acquires the indicator device ID described in column Cd of the same row as the transaction processing apparatus ID by referring to the lane table 1032 as ACT208. Then, the processor 101 outputs a signal indicating activation of the instruction to the indicator device 50 identified by the indicator device ID as ACT209. The signal indicating activation of the instruction is transmitted to the indicator device 50 via the settlement device 40. The signal indicating activation of the instruction is a signal that enables the functions as the reception means 5011 and the instruction means 5012 of the indicator device 50. Hereinafter, the transaction file stored in the employee-specific folder 1033 is referred to as the third transaction file.

[0176] The indicating device 50 usually displays an indication screen SEa (see FIG. 36) on the touch panel 505. FIG. 36 is an example of a display of the indication screen SEa. The indication screen SEa includes a pull-down area AEa in which the names of the respective clerks are displayed as a pull-down menu. The indication screen SEa also has a call button BEa arranged thereon. The call button BEa is a software key. The call button BEa is a first operator for instructing to transmit a transaction file to the settlement device 40.

[0177] Normally, the input of the call button BEa is invalid. For example, the call button BEa is grayed out and in a state where it cannot be input. When the indicating device 50 receives a signal indicating activation of an instruction from the hold server 10, the call button BEa is made inputtable, and the input of the call button BEa is enabled. The indicating device 50 that displays such an indication screen SEa realizes a function as a reception means 5011. Note that the information displayed in the pull-down area AEa may be an employee code instead of a name. Alternatively, it may be both a name and an employee code.

[0178] A clerk who has signed on to the transaction processing device 30 as an operator of the input device 20 operates the pull-down area AEa to select his or her own name from the pull-down menu. By such an operation, the employee code of the clerk is overwritten and stored in the employee memory 5031. Such an operation may be performed immediately after the clerk signs on, or may be performed at any subsequent time.

[0179] Also, the store clerk who has determined the payment destination operates the instruction device 50 or the transaction processing device 30 based on that determination. Specifically, the store clerk who has determined the settlement device 40 as the payment destination inputs the call button BEa of the instruction device 50. When the call button BEa is input, upon receiving an instruction from the instruction device 50, a first signal is output from the settlement device 40. The first signal output from the settlement device 40 is transmitted to the hold server 10. The first signal is a signal output in response to the input of the call button BEa. The first signal is a signal indicating that the settlement device 40 has been determined as the payment destination. The first signal includes the employee code stored in the employee memory 5031. The instruction device 50 that outputs the first signal realizes the function as the instruction means 5012.

[0180] On the other hand, the store clerk who has determined the transaction processing device 30 as the payment destination inputs the hold cancellation button BDa. When the hold cancellation button BDa is input, a second signal is output from the transaction processing device 30 to the hold server 10. The second signal is a signal output in response to the input of the hold cancellation button BDa. The second signal is a signal indicating that the transaction processing device 30 has been determined as the payment destination. The second signal includes the employee code stored in the employee memory 3026.

[0181] The processor 101 that outputs a signal indicating activation of the instruction proceeds to ACT211 in FIG. 18. The processor 101 checks whether the call button BEa has been input as ACT211. If the call button BEa has not been input, that is, if the first signal has not been received, the processor 101 proceeds to ACT212. The processor 101 checks whether the hold cancellation button BDa has been input as ACT212. If the hold cancellation button BDa has not been input, that is, if the second signal has not been received, the processor 101 returns to ACT211. In this way, the processor 101 waits in ACT211 and ACT212 for the call button BEa on the instruction screen SEa to be input or for the hold cancellation button BDa on the guidance screen SDa to be input.

[0182] In the standby states of ACT211 and ACT212, when receiving an instruction from the instruction device 50 and receiving the first signal output from the settlement device 40, the processor 101 recognizes that the call button BEa has been input. The processor 101 proceeds to ACT213. The processor 101 refers to the lane table 1032 as ACT213 and acquires the settlement device ID described in the column Cc of the same row as the transaction processing device ID. Then, the processor 101 sends an execution event to the settlement device 40 identified by that settlement device ID as ACT214. The execution event is an event that requests the execution of settlement processing.

[0183] Details will be described later with reference to FIG. 19, but a permission response or a negative response is returned from the settlement device 40 that has received the execution event. The permission response is returned when the settlement of the transaction is possible in the settlement device 40. The negative response is returned when the settlement of the transaction is impossible in the settlement device 40.

[0184] The processor 101 that has sent the execution event proceeds to ACT215. The processor 101 checks as ACT215 whether a permission response has been received. If a permission response is received, the processor 101 proceeds to ACT216. The processor 101 acquires the employee code from the first signal as ACT216. Note that the processor 101 may refer to the lane table 1032 and acquire the employee code described in the column Ce of the same row as the transaction processing device ID obtained in the process of ACT204.

[0185] The processor 101 that has acquired the employee code selects the employee-specific folder 1033 of that employee code as ACT217. Then, the processor 101 sends the third transaction file held in the selected employee-specific folder 1033 to the settlement device 40 as ACT218. That is, the processor 101 sends the third transaction file stored in the employee-specific folder 1033 of the employee code acquired in ACT216 to the settlement device 40 identified by the settlement device ID obtained in the process of ACT213.

[0186] The processor 101 that has transmitted the transaction file proceeds to ACT219. The processor 101 transmits a cancellation notice event to the transaction processing device 30 that is the source of the third transaction file as ACT219. That is, the processor 101 transmits a cancellation notice event to the transaction processing device 30 identified by the transaction processing device ID acquired in the process of ACT204. The cancellation notice event is an event that notifies that the hold state has been cancelled.

[0187] The processor 101 that has transmitted the cancellation notice event proceeds to ACT220. The processor 101 deletes the third transaction file as ACT220. That is, the processor 101 deletes the third transaction file stored in the employee - specific folder 1033 selected in ACT217. Thus, the processor 101 ends the fourth information processing.

[0188] On the other hand, when the processor 101 receives the second signal from the transaction processing device 30 in the waiting states of ACT211 and ACT212, the processor 101 recognizes that the hold - release button BDa has been input. The processor 101 proceeds to ACT221. The processor 101 acquires the employee code from the second signal as ACT221. Note that the processor 101 may also acquire the employee code described in the column Ce of the same row as the transaction processing device ID acquired in the process of ACT204 by referring to the lane table 1032.

[0189] The processor 101 that has acquired the employee code selects the employee - specific folder 1033 of that employee code as ACT222. Then the processor 101 transmits the third transaction file held in the selected employee - specific folder 1033 to the transaction processing device 30 as ACT223. That is, the processor 101 transmits the third transaction file stored in the employee - specific folder 1033 selected in ACT222 to the transaction processing device 30 identified by the transaction processing device ID acquired in the process of ACT204.

[0190] The processor 101 that has sent the third transaction file proceeds to ACT224. The processor 101 deletes the third transaction file as ACT224. That is, the processor 101 deletes the third transaction file stored in the employee - specific folder 1033 selected in ACT222. Thus, the processor 101 ends the fourth information processing.

[0191] In addition, when a negative response is received in ACT215, the processor 101 proceeds to ACT225. The processor 101 outputs an error signal to the indicating device 50 as ACT225. The indicating device 50 that has received the error signal sets the screen of the touch panel 505 as an error screen. An operator (software key) for instructing error cancellation is displayed on the error screen.

[0192] The store clerk who has checked the error screen inputs an operator for instructing error cancellation. When this operator is input, an error cancellation signal is output from the indicating device. The error cancellation signal is sent to the hold server 10 via the settlement device 40. Also, the screen of the touch panel 505 returns to the instruction screen SEa.

[0193] The processor 101 that has output the error signal proceeds to ACT226. The processor 101 waits for an error cancellation signal as ACT226. When the error cancellation signal is received via the communication interface 105, the processor 101 returns to the waiting states of ACT211 and ACT212.

[0194] For example, when a store clerk inputs the call button BEa and designates the settlement device 40 as the output destination of information related to the transaction, there may be a case where the previous customer has not yet completed the settlement in the settlement device 40. In such a case, since the screen of the indicating device 50 becomes an error screen, the store clerk inputs an operator for instructing error cancellation. Then, since the screen of the indicating device 50 returns to the instruction screen SEa, the store clerk may wait for the previous customer to complete the settlement and then input the call button BEa. Alternatively, when the customer who was performing the settlement with the transaction processing device 30 has completed the settlement first, the store clerk may input the hold cancellation button BDa.

[0195] Here, the processor 101 realizes the function as the transaction information input means 1011 by executing the processing of ACT201 and ACT203 in cooperation with the communication interface 105. The processor 101 realizes the function as the reservation means 1012 by executing the processing of ACT204 to ACT207 in cooperation with the employee-specific folder 1033. The processor 101 realizes the function as the output destination recognition means 1013 by executing the processing of ACT211 and ACT212 in cooperation with the communication interface 105. The processor 101 realizes the function as the operator recognition means 1014 by executing the processing of ACT216 and ACT221 in cooperation with the lane table 1032. The processor 101 realizes the function as the reservation information output means 1015 by executing the processing of ACT217, ACT218 and the processing of ACT222, ACT223 in cooperation with the communication interface 105.

[0196] Thus, the transaction file (the first transaction file), that is, the information related to the transaction output from the transaction processing device 30 to the reservation server 10 is stored, that is, reserved for each clerk standing in the settlement lane L in the employee-specific folder 1033 in the reservation server 10. Then, when the clerk inputs the call button BEa of the instruction device 50, a first signal is transmitted from the instruction device 50 to the settlement device 40. In response to this first signal, the transaction file (the third transaction file) reserved in the reservation server 10 is transmitted to the settlement device 40. At this time, a release notification event is transmitted from the reservation server 10 to the transaction processing device 30 in the same settlement lane L. On the other hand, when the clerk inputs the reservation cancellation button BDa of the transaction processing device 30, a reservation cancellation event is transmitted from the transaction processing device 30 to the settlement device 40. In response to this reservation cancellation event, the transaction file (the third transaction file) reserved in the reservation server 10 is transmitted to the transaction processing device 30.

[0197] Return to the description of FIG. 16. The processor 301 that controls the display of the guidance screen SDa in ACT182 proceeds to ACT183. The processor 301 checks whether a cancellation notice event has been received as ACT183. If the cancellation notice event has not been received, the processor 301 proceeds to ACT184. The processor 301 checks whether the hold cancellation button BDa has been input as ACT184. If the hold cancellation button BDa has not been input, the processor 301 returns to ACT183. In this way, the processor 301 waits for a cancellation notice event to be received or the hold cancellation button BDa to be input in ACT183 and ACT184.

[0198] As described with reference to FIGS. 17 and 18, when the call button BEa is input on the instruction screen SEa displayed on the instruction device 50 and the transaction file (third transaction file) held by the hold server 10 is output to the settlement device 40, a cancellation notice event is transmitted from the hold server 10 to the transaction processing device 30. When the processor 301 receives a cancellation notice event in the waiting states of ACT183 and ACT184, it proceeds to ACT185. The processor 301 displays a pop-up PUd (see FIG. 37) for guiding the settlement by the settlement device 40 on the subtotal screen SAb or the payment screen SAd of the touch panel 23 as ACT185. Further, the processor 301 displays a text TXd (see FIG. 38) for instructing the customer to make a payment by the settlement device 40 on the subtotal screen SBb of the display 25.

[0199] FIG. 37 is an example of the pop-up PUd displayed on the payment screen SAd of the touch panel 23. The store clerk who has confirmed the pop-up PUd guides the customer to the settlement device 40.

[0200] FIG. 38 is an example of the text TXd displayed on the subtotal screen SBb of the display 25. The customer who has confirmed the text TXd moves to the settlement device 40 according to the guidance of the store clerk and makes a payment.

[0201] When the processing of ACT185 is completed, the processor 301 sets the pending flag Fb to "0" as ACT186. Thus, the processor 301 finishes the third information processing.

[0202] On the other hand, when the cancel button BDa is input while the processor 301 is in the waiting state of ACT183 and ACT184, the processor 301 proceeds to ACT187. The processor 301 checks the payment-in-progress flag Fa as ACT187. Here, if the payment-in-progress flag Fa is "1", that is, if the previous customer is executing settlement in the transaction processing device 30, the processor 301 returns to ACT183. The processor 301 invalidates the input of the cancel button BDa and returns to the waiting state of ACT183 and ACT184.

[0203] If the payment-in-progress flag Fa is "0" in ACT187, that is, if there is no customer performing settlement in the transaction processing device 30, the processor 301 proceeds to ACT188. The processor 301 acquires the employee code from the employee memory 3026 as ACT188. Then the processor 301 sends a cancellation event to the reservation server 10 as ACT189. The cancellation event includes the employee code acquired from the employee memory 3026.

[0204] As described with reference to FIG. 18, the reservation server 10 that has received the cancellation event from the transaction processing device 30 sends the reserved transaction file (the third transaction file) to the transaction processing device 30. Therefore, the processor 301 that has sent the cancellation event waits to receive the transaction file as ACT190. When the transaction file is received via the communication interface 305, the processor 301 proceeds to ACT191. The processor 301 stores the transaction file in the second file area 3022 as ACT191. Incidentally, the received transaction file is the transaction file output to the reservation server 10 in ACT148 of FIG. 14. Hereinafter, the transaction file received from the reservation server 10 and stored in the second file area 3022 is referred to as the fourth transaction file.

[0205] The processor 301 that stores the fourth transaction file in the second file area 3022 proceeds to ACT192. The processor 301, as ACT192, displays a pop-up PUb (see FIG. 29) notifying that payment can be made by the transaction processing device 30 on the subtotal screen SAb or the payment screen SAd of the touch panel 23. Further, the processor 301 displays a text TXb (see FIG. 30) for instructing that payment can be made on the subtotal screen SBb of the display 25.

[0206] In this way, the processor 301 that has notified that payment can be made by the transaction processing device 30 using the touch panel 23 and the display 25 proceeds to ACT193. The processor 301, as ACT193, sets the payment-in-progress flag Fa to "1" and the pending flag Fb to "0". Thereafter, the processor 301 proceeds to ACT162 in FIG. 15. Then, the processor 301 executes the processes from ACT162 to ACT177 in the same manner as described above.

[0207] In this way, when the transaction file held in the hold server 10 is returned to the transaction processing device 30, the processor 301 of the transaction processing device 30 executes the processes of ACT162 to ACT177 in FIG. 15 in the same manner as described above. That is, the processor 301 sets the screen of the second touch panel 33 as the payment notification screen SCb. When the payment method is not selected in the input device 20, the processor 301 displays the payment method selection screen SCa before the payment notification screen SCb. When the payment method is selected by the customer's operation, the processor 301 displays the payment notification screen SCb. After that, when the payment is started, the processor 301 sets the screen of the second touch panel 33 as the payment in progress screen SCc. The processor 301 also assigns a transaction number. When the accounting button BCb on the payment in progress screen SCc is input by the customer's operation, the processor 301 executes the settlement process and issues a receipt. The processor 301 also sets the screen of the second touch panel 33 as the payment completed screen SCd. Thus, the customer can settle the transaction by operating the transaction processing device 30 self-service to pay the price.

[0208] Here, the processor 301 realizes the function as the guidance means 3017 by executing the processes of ACT185 and ACT192 in cooperation with the touch panel 23 and the display 25. The processor 301 realizes the function as the hold cancellation means 3018 by executing the processes of ACT184 to ACT189. The processor 301 realizes the function as the execution means 3019 by executing the processes of ACT190 to ACT193 and the subsequent processes of ACT162 to ACT172.

[0209] FIG. 19 is a flowchart showing the main procedure of the fifth information process executed by the processor 401 of the settlement device 40 according to the third business program. The processor 401 is waiting for an execution event as ACT301.

[0210] As described with reference to FIG. 18, when the call button BEa on the instruction screen SEa displayed on the instruction device 50 is input and the settlement device 40 is instructed as the output destination of the information related to the transaction while the transaction file is on hold in the employee folder 1033 of the hold server 10, an execution event is transmitted from the hold server 10 to the settlement device 40 as the process of ACT214. When the processor 401 receives the execution event, it proceeds to ACT302. The processor 401 checks the payment-in-progress flag Fc as ACT302. Here, if the payment-in-progress flag Fc is "1", that is, if the previous customer is still making a settlement in the settlement device 40, the processor 301 proceeds to ACT303. The processor 401 transmits a negative response signal to the hold server 10 as ACT303. Thus, the processor 401 ends the fifth information process.

[0211] On the contrary, if the payment-in-progress flag Fc is "0" in ACT302, that is, if the customer is not making a settlement in the settlement device 40, the processor 401 proceeds to ACT304. The processor 301 transmits a permission response signal to the hold server 10 as ACT304.

[0212] As described with reference to FIG. 18, the hold server 10 that has received the permission response from the settlement device 40 that transmitted the execution event transmits the transaction file (the third transaction file) held in that settlement device 40. Therefore, the processor 401 that transmitted the permission response signal waits to receive the transaction file as ACT305. When the transaction file is received via the communication interface 405, the processor 401 proceeds to ACT306. The processor 401 stores the transaction file in the third file area 4021 as ACT306. Incidentally, the transaction file is stored in the first file area 3021 of the transaction processing device 30 installed in the same settlement lane L and is the transaction file output to the hold server 10. Hereinafter, the transaction file stored in the third file area 4021 is referred to as the fifth transaction file.

[0213] The processor 401 that has saved the fifth transaction file in the third file area 4021 proceeds to ACT307. The processor 401 sets the payment-in-progress flag Fc to "1" as ACT307. With this, the processor 401 ends the fifth information processing.

[0214] In this way, when the processor 401 of the settlement device 40 receives an execution event from the hold server 10 while the payment-in-progress flag Fc is "0", that is, when the customer has not performed settlement, the processor 401 then takes in the transaction file output from the hold server 10 and saves it in the third file area 4021. Also, the processor 401 sets the payment-in-progress flag Fc to "1".

[0215] Here, the processor 401 realizes the function as the capturing means 4011 by executing the processes of ACT305 and ACT306 in cooperation with the communication interface 405.

[0216] FIG. 20 is a flowchart showing the main procedure of the sixth information processing executed by the processor 401 of the settlement device 40 according to the third service program. The processor 401 executes the sixth information processing in parallel with the fifth information processing described above.

[0217] The processor 401 waits for the payment-in-progress flag Fc to become "1" as ACT311. When the payment-in-progress flag Fc becomes "1" in ACT307 of the fifth information processing, the processor 401 proceeds to ACT312. The processor 401 sets the screen of the touch panel 41 to the detail confirmation screen SFa (see FIG. 39) as ACT312.

[0218] FIG. 39 is an example of a detailed confirmation screen SFa displayed on the touch panel 41. The detailed confirmation screen SFa is divided into a detail area AFa and a total area AFb. The detail area AFa is an area that displays, in a list format, the name of the purchased product, the quantity purchased, the unit price, the discount amount, and the sales amount of the purchased products in a single transaction in ascending order of a series of numbers. The total area AFb is an area that displays the total quantity purchased and the total sales amount of the purchased products in a single transaction. The processor 401 causes the detail area AFa to display the name of the purchased product, the quantity purchased, the unit price, the discount amount, and the sales amount of the purchased products in a single transaction based on the product sales data of the fifth transaction file stored in the third file area 4021. Further, the processor 401 causes the total area AFb to display the total quantity purchased and the total sales amount of the purchased products based on the product sales data.

[0219] The detailed confirmation screen SFa includes a confirmation button BFa and a clerk call button BFb. The confirmation button BFa and the clerk call button BFb are software keys. The confirmation button BFa is an operator for instructing that the customer has confirmed that the details of the purchased products are displayed on the detailed confirmation screen SFa. The clerk call button BFb is an operator for instructing the customer to call a clerk.

[0220] The processor 401 that has displayed the detailed confirmation screen SFa proceeds to ACT313. The processor 401 waits for the confirmation button BFa to be input as ACT313. When the confirmation button BFa is input, the processor 401 proceeds to ACT314. The processor 401 checks whether the payment code is included in the transaction file stored in the third file area 4021 as ACT314. If the payment code is included, the processor 401 proceeds to ACT315. The processor 401 extracts the payment code from the transaction file as ACT315.

[0221] On the other hand, if the payment code is not included, the processor 401 proceeds to ACT316. The processor 401 sets the screen of the touch panel 41 to a payment method selection screen SFb (see FIG. 40) as ACT316.

[0222] Figure 40 is an example of a payment method selection screen SFb displayed on the touch panel 41. The payment method selection screen SFb includes a group of selection buttons BFc for each payment method. The group of selection buttons BFc includes a cash button, a credit button, an electronic money button, and a code settlement button. The payment method selection screen SFb includes a total area AFc where the total purchase quantity and the total sales amount of the purchased goods in one transaction are displayed. In the total area AFc, the total purchase quantity and the total sales amount calculated based on the product sales data of the fifth transaction file are displayed. Note that the clerk call button BFb is also displayed on the payment method selection screen SFb, and the customer can call the clerk.

[0223] The customer who has confirmed the payment method selection screen SFb touches the button of the desired payment method. For example, a customer who wishes to pay in cash touches the cash button in the group of selection buttons BFc. For example, a customer who wishes to pay with a credit card touches the credit button in the group of selection buttons BFc. For example, a customer who wishes to pay with electronic money touches the electronic money button in the group of selection buttons BFc. For example, a customer who wishes to pay by code settlement touches the code settlement button in the group of selection buttons BFc. Note that as described above, it is not necessarily required that the information related to the transaction held in the hold server 10 includes the payment method for the payment received by the first payment acceptance means 2013. Therefore, in the case of an operation where the information related to the transaction does not include the payment method for the payment received by the first payment acceptance means 2013, the processing steps of ACT314 and ACT315 may be omitted.

[0224] The processor 401 that sets the screen of the touch panel 41 as the payment method selection screen SFb proceeds to ACT317. The processor 401 waits for a payment method to be selected as ACT317. When any payment method is selected by a touch operation on the selection button group BFc, the processor 401 proceeds to ACT318. The processor 401, as ACT318, acquires the payment code of the selected payment method in the same manner as the processing of ACT123 of the first information processing.

[0225] After finishing the processing of ACT315 or ACT318, the processor 401 proceeds to ACT319. The processor 401 sets the screen of the touch panel 41 as the payment notification screen SFc (see FIG. 41) as ACT319. The payment notification screen SFc is a screen based on the payment code obtained by the processing of ACT315 or ACT318.

[0226] FIG. 41 is an example of the payment notification screen SFc displayed on the touch panel 41. FIG. 41 shows the payment notification screen SFc when the payment code for cash payment is obtained by the processing of ACT315 or ACT318. The payment notification screen SFc includes a total area AFc similar to the payment method selection screen SFb. The payment notification screen SFc also includes a change machine information area AFd. In the change machine information area AFd, the total amount, the total amount of cash inserted into the automatic change machine 43, so-called the inserted amount, and the balance obtained by subtracting the inserted amount from the total amount are displayed. Note that the clerk call button BFb is also displayed on the payment notification screen, and the customer can call the clerk.

[0227] Customers who have confirmed the payment notification screen SFc pay the amount in the payment method they have selected. For example, a customer who has selected cash payment inserts cash into the automatic change machine 43. A customer who has selected credit card payment has the credit card data read by the reader of the cashless payment terminal 44. A customer who has selected electronic money payment has the electronic money medium data read by the reader of the cashless payment terminal 44. A customer who has selected code settlement payment has the barcode or two-dimensional data code for code settlement read by the scanner of the cashless payment terminal 44.

[0228] The processor 401 that has set the screen of the touch panel 41 as the payment notification screen SFc proceeds to ACT320. The processor 401 waits for the start of the payment of the amount as ACT320. For example, when cash payment is selected, the processor 401 waits for cash to be inserted into the automatic change machine 43. For example, when credit card payment is selected, the processor 401 waits for the credit card data to be read by the cashless payment terminal 44. For example, when electronic money payment is selected, the processor 401 waits for the electronic money data to be read by the cashless payment terminal 44. For example, when code settlement payment is selected, the processor 401 waits for the barcode or two-dimensional data code for code settlement to be read by the cashless payment terminal 44.

[0229] When the payment of the amount starts, the processor 401 proceeds to ACT321. The processor 401 issues a transaction number as ACT321. The transaction number is, for example, a 7-digit number obtained by attaching a 4-digit serial number to a 3-digit settlement device ID. The serial number is incremented by "1" each time a transaction is settled in the settlement device 40. The processor 401 that has issued the transaction number proceeds to ACT322. The processor 401 sets the screen of the touch panel 41 as the payment in progress screen SFd (see FIG. 42) as ACT322.

[0230] FIG. 42 is an example of a payment-in progress screen SFd displayed on the touch panel 41. FIG. 42 shows the payment-in progress screen SFd when a payment code for cash payment is obtained by the process of ACT315 or ACT318. The payment-in progress screen SFd is a screen obtained by adding an accounting button BFd to the payment notification screen SCb. In the payment-in progress screen SCc, the information displayed in the change machine information area AFd is updated according to the amount of cash inserted into the automatic change machine 43. The accounting button BFd is a software key. The accounting button BFd is an operator for instructing the end of payment of the price. A customer who has finished paying the price by the selected payment method touches the accounting button BFd. Note that the clerk call button BFb is continuously displayed also on the payment-in progress screen SFd, and the customer can call the clerk.

[0231] The processor 401 that sets the screen of the touch panel 41 as the payment-in progress screen SFd proceeds to ACT323. The processor 401 waits for the accounting button BFd to be input as ACT323. When the accounting button BFd is input by a touch operation, the processor 401 proceeds to ACT324. The processor 401 executes a settlement process of the transaction based on the payment code as ACT324. That is, when the payment code is a cash payment code, the processor 401 executes a settlement process of the transaction with the cash inserted into the automatic change machine 43. When the payment code is a credit card payment code, the processor 401 executes a settlement process of the transaction with the credit card data read by the cashless settlement terminal 44. When the payment code is an electronic money payment code, the processor 401 executes a settlement process of the transaction with the electronic money data read by the cashless settlement terminal 44. When the payment code is a code settlement payment code, the processor 401 executes a settlement process of the transaction with the barcode or two-dimensional data code read by the cashless settlement terminal 44. Since these settlement processes are all well-known, detailed descriptions are omitted.

[0232] After finishing the settlement process, the processor 401 proceeds to ACT325. The processor 401 drives the printer 42 as ACT325 to issue a receipt. Also, the processor 401 sets the screen of the touch panel 41 as the payment completion screen SFe (see FIG. 43) as ACT326. The receipt is the same as the receipt issued in the process of ACT173 in the transaction processing device 30. However, a transaction number including the transaction processing device ID is printed on the receipt issued from the transaction processing device 30, while a transaction number including the settlement device ID is printed on the receipt issued from the settlement device 40.

[0233] FIG. 43 is an example of the payment completion screen SFe displayed on the touch panel 41. FIG. 43 shows the payment completion screen SFe when the payment code for cash payment is obtained by the process of ACT315 or ACT318. The payment completion screen SFe includes the same change machine information area AFd as the payment notification screen SFc and the payment in progress screen SFd. The store clerk can know that the payment of the customer who selected cash payment has been completed based on the information displayed in the change machine information area AFd. Note that since the customer who has completed the payment does not call the store clerk, the store clerk call button BFb is not displayed on the payment completion screen SFe. The customer who has confirmed the payment completion screen SFe will take the receipt and leave the store.

[0234] The processor 401 that has displayed the payment completion screen SFe proceeds to ACT327. The processor 401 saves the data of the fifth transaction file stored in the third file area 4021 as ACT327, that is, the data of the goods purchased by the customer who has completed the settlement. The storage destination of the data is, for example, the auxiliary storage device 403. The storage destination of the data may be the main memory 402. Alternatively, the fifth transaction file may be transmitted to the POS server via the communication interface 405 and stored by the POS server. It may be stored by the hold server 10 instead of the POS server.

[0235] The processor 401 that has saved the data of the fifth transaction file proceeds to ACT328. The processor 401 clears the third file area 4021 as ACT328. Also, the processor 401 sets the payment-in progress flag Fc to "0" as ACT329. Thus, the processor 401 finishes the sixth information process.

[0236] In this way, when the transaction file (the third transaction file) held in the hold server 10 is taken into the settlement device 40, the processor 401 of the settlement device 40 executes the processes of ACT312 to ACT329 in FIG. 20. That is, the processor 401 sets the screen of the touch panel 41 as the detail confirmation screen SFa. Then, when the confirmation button BFa is input by the customer's operation, the processor 401 sets the screen of the touch panel 41 as the payment notification screen SFc. Note that when the payment method is not selected in the input device 20, the processor 401 displays the payment method selection screen SFb before the payment notification screen SFc. Then, when the payment method is selected by the customer's operation, the processor 401 sets the screen of the touch panel 41 as the payment notification screen SFc. After that, when the payment is started, the processor 401 sets the screen of the touch panel 41 as the payment-in progress screen SFd. Also, the processor 401 assigns a transaction number. Then, when the accounting button BFd on the payment-in progress screen SFd is input by the customer's operation, the processor 401 executes the settlement process and issues a receipt. Also, the processor 401 sets the screen of the touch panel 41 as the payment completion screen SFe. Thus, the customer can settle the transaction by operating the settlement device 40 self-service to pay the amount.

[0237] Here, the processor 401 realizes the function as the third payment reception means 4013 by executing the process of ACT316 in cooperation with the touch panel 41. The processor 401 realizes the function as the second amount output means 4012 by executing the process of ACT319 in cooperation with the touch panel 41. The processor 401 realizes the function as the second settlement means 4014 by executing the process of ACT324.

[0238] [Explanation of the operation of the payment system] Next, the operation of the payment system 100 operating as described above will be explained using the sequence diagrams of FIGS. 44 to 46. In FIG. 44, the store clerk starts a transaction with the first customer A. That is, the store clerk operates the input device 20 to register the purchased goods of customer A (Goods registration A). When the purchased goods are registered, the transaction processing device 30 creates a transaction file A. When the registration of the purchased goods is completed, the store clerk inputs the payment button BAe or the payment button BAh (Payment input A). The transaction processing device 30 determines whether the transaction can be settled. At this point, since the transaction can be settled, the transaction processing device 30 saves the transaction file A in the second file area 3022. Customer A moves to the location where the transaction processing device 30 is installed and starts paying the price (Payment start A).

[0239] The store clerk starts a transaction with the second customer B. That is, the store clerk operates the input device 20 to register the purchased goods of customer B (Goods registration B). When the purchased goods are registered, the transaction processing device 30 creates a transaction file B. When the registration of the purchased goods is completed, the store clerk inputs the payment button BAe or the payment button BAh (Payment input B). The transaction processing device 30 determines whether the transaction can be settled. At this point, if customer A has not completed the payment, the transaction cannot be settled. The transaction processing device 30 transmits the transaction file B to the hold server 10. The hold server 10 saves the transaction file B. Since the transaction file B has been transmitted to the hold server 10, a guidance screen SDa is displayed on the first touch panel 32 of the transaction processing device 30, so the store clerk inputs the call button BEa displayed on the touch panel 505 of the indicating device 50. When the call button BEa is input, a first signal is transmitted from the settlement device 40 to the hold server 10 in response to an instruction from the indicating device 50. In response to this first signal, the transaction file B is transmitted from the hold server 10 to the settlement device 40. The settlement device 40 saves the transaction file B in the third file area 4021. Customer B moves to the location where the settlement device 40 is installed and starts paying the price (Payment start B).

[0240] The clerk starts a transaction with the third customer C. That is, the clerk operates the input device 20 to register the purchased items of customer C (item registration C). When the purchased items are registered, the transaction processing device 30 creates a transaction file C. When the registration of the purchased items is completed, the clerk inputs the payment button BAe or the payment button BAh (payment input C). The transaction processing device 30 determines whether the transaction can be settled. At this point, if customer A has completed the payment of the purchase price, the transaction processing device 30 saves the transaction file C in the second file area 3022. Customer C moves to the location where the transaction processing device 30 is installed and starts to make the payment (payment start C).

[0241] The clerk starts a transaction with the fourth customer D. That is, the clerk operates the input device 20 to register the purchased items of customer D (item registration D). When the purchased items are registered, the transaction processing device 30 creates a transaction file D. When the registration of the purchased items is completed, the clerk inputs the payment button BAe or the payment button BAh (payment input D). The transaction processing device 30 determines whether the transaction can be settled. At this point, if neither customer B nor customer C has completed the payment of the purchase price, information indicating that payment is not possible is displayed on the touch panel 23 and the display 25 of the input device 20. Customer D waits until payment becomes possible.

[0242] Here, if customer C's payment is completed first, the transaction processing device 30 saves the transaction file D in the second file area 3022. Customer D moves to the location where the transaction processing device 30 is installed and starts to make the payment (payment start Da).

[0243] On the other hand, as shown in FIG. 45, when the payment by Customer B is completed first, the transaction processing device 30 transmits the transaction file D to the hold server 10. The hold server 10 stores the transaction file D. Also, since the call button BEa on the instruction screen SEa displayed on the touch panel 505 of the instruction device 50 becomes valid, the store clerk inputs the call button BEa. When the call button BEa is input, a first signal is transmitted from the settlement device 40 to the hold server 10 in response to the instruction from the instruction device 50. In response to this first signal, the transaction file D is transmitted from the hold server 10 to the settlement device 40. The settlement device 40 stores the transaction file D in the third file area 4021. Customer D moves to the location where the settlement device 40 is installed and starts paying the amount (payment start Db).

[0244] On the other hand, as shown in FIG. 46, if the payment by Customer B is completed first, but then immediately Customer C also completes the payment and the transaction processing device 30 becomes available, the store clerk may input the hold cancellation button BDa on the guidance screen SDa displayed on the first touch panel 32. When the hold cancellation button BDa is input, a second signal is transmitted from the transaction processing device 30 to the hold server 10. In response to this second signal, the transaction file D is transmitted from the hold server 10 to the transaction processing device 30. The transaction processing device 30 stores the transaction file D in the second file area 3022. Customer D moves to the location where the transaction processing device 30 is installed and starts paying the amount (payment start Dc).

[0245] Since the payment system 100 operates as described above, the transaction processing device 30 and the settlement device 40 can be appropriately selected to efficiently handle many customers. Moreover, since the customer himself / herself performs the operation related to the payment of the amount, it is possible to reduce labor costs. Also, since the store clerk does not touch cash, a cash card, etc., it can have an excellent effect in terms of infection prevention measures.

[0246] <Configuration and operation related to the correction process of transactions settled by the settlement device> Incidentally, when the registration of purchased items is completed by the operation of a store clerk on the input device 20 and subsequently the settlement of the transaction is performed by the operation of a customer on the transaction processing device 30 or the payment device 40, it is assumed that correction operations such as the return of purchased items, the change of the purchase quantity, and the addition of purchased items related to the transaction may occur. Such correction operations are handled by the store clerk standing in the space SP.

[0247] Regarding the transaction settled by the transaction processing device 30, the transaction file storing the information related to the transaction is stored in the second file area 3022. Therefore, by the store clerk operating the keyboard 31 or the first touch panel 32 of the transaction processing device 30, the data of the transaction file can be corrected. Thus, regarding the correction operations of the transaction settled by the transaction processing device 30, the store clerk standing in the space SP can easily handle them.

[0248] However, regarding the transaction settled by the payment device 40, the transaction file storing the information related to the transaction is output from the holding server 10 to the payment device 40 and does not exist in the transaction processing device 30. Therefore, unless the transaction file is called back to the transaction processing device 30, the store clerk standing in the space SP cannot perform the correction operations. In other words, in order to implement the correction operations of the transaction settled by the payment device 40, a mechanism for calling back the transaction file output to the payment device 40 to the transaction processing device 30 is required, and the system configuration becomes complicated.

[0249] Therefore, next, an embodiment of the payment system 200 that enables the correction of a transaction settled by the payment device 40 without calling back the transaction file output to the payment device 40 to the transaction processing device 30 will be described with reference to FIGS. 47 to 57. For the sake of convenience of explanation, the embodiment of the payment system 100 described with reference to FIGS. 1 to 46 is referred to as the first embodiment, and the embodiment of the payment system 200 described later is referred to as the second embodiment. And regarding the payment system 200, it will be described by specializing in the points different from the first embodiment. At that time, the parts common to the payment system 100 are denoted by the same reference numerals, and the detailed description is omitted.

[0250] [Description of the Configuration of the Payment System 200] Compared with the payment system 100, in the payment system 200, a part of the storage area formed in the main memory 302 of the transaction processing device 30 and a part of the functional configurations respectively possessed by the transaction processing device 30, the payment device 40, and the instruction device 50 are different. Also, the configuration of the instruction screen displayed on the touch panel 51 of the instruction device 50 is different.

[0251] FIG. 47 is a schematic diagram showing the main storage areas formed in the main memory 302 of the transaction processing device 30. The transaction processing device 30 has newly added an area of a copy file area 3027 to a part of the volatile storage area in the main memory 302. The copy file area 3027 is an area for storing a copy of the transaction file output to the hold server 10 by the transaction information output means 3016.

[0252] FIG. 48 is a schematic diagram showing parts other than the functional configurations of each part of the payment system 100 among the functional configurations respectively possessed by the transaction processing device 30, the payment device 40, and the instruction device 50. Although not shown, it goes without saying that in the payment system 200 as well, the hold server 10, the input device 20, the transaction processing device 30, the payment device 40, and the instruction device 50 have the respective functional configurations described with reference to FIG. 10.

[0253] In the payment system 200, the transaction processing device 30 further has functions as a copy means 3031, a correction means 3032, and a prohibition means 3033. The copy means 3031 is a function of copying information related to a transaction held by the hold means 1012 of the hold server 10. The hold means 1012 holds information related to a transaction output by the transaction information output means 3016 of the transaction processing device 30, that is, holds the transaction file. That is, the copy means 3031 copies the transaction file output to the hold server 10 by the transaction information output means 3016 of the transaction processing device 30. The copy means 3031 stores the copied transaction file in the copy file area 3027. Hereinafter, the copied transaction file is referred to as a copy transaction file.

[0254] The correction means 3032 is a function for correcting the information of the copy transaction file stored in the copy file area 3027. The correction means 3032 corrects the information of the copy transaction file on the condition that the settlement in the settlement device 40 is interrupted for the transaction in which the transaction file, which is the data before copying of the copy transaction file, is created. Information related to purchased goods and the like is stored in the copy transaction file as information related to the transaction with the customer. The correction means 3032 deletes, for example, the information related to the purchased goods. The correction means 3032 changes, for example, the purchase quantity of the information related to the purchased goods. The correction means 3032 adds, for example, information related to new purchased goods to the copy transaction file.

[0255] The prohibition means 3033 is a function for prohibiting the operation of the customer on the transaction processing device 30 during the operation of correcting the information related to the transaction by the correction means 3032. The prohibition means 3033 controls not to accept the input of the second touch panel 33, which is the customer operation device provided in the transaction processing device 30. The prohibition means 3033 may further control not to accept the input of the automatic change machine 35 and the cashless settlement terminal 36. The prohibition means 3033 preferably notifies that the operation of the customer is prohibited by displaying an image indicating that the operation of the customer is not accepted on the screen of the second touch panel 33. Since the prohibition means 3033 invalidates the second touch panel 33, it can be paraphrased as an invalidation means or the like.

[0256] The instruction device 50 further has functions as an interruption reception means 5013 and an interruption instruction means 5014. The interruption reception means 5013 is a function for receiving an instruction to interrupt the settlement of a transaction processed by the second settlement means 4014 of the settlement device 40. The instruction device 50 has a third operator for receiving an instruction to interrupt the settlement of a transaction. When a tablet terminal is used as the instruction device 50, the third operator is a software key displayed on the liquid crystal screen of the tablet terminal. The interruption reception means 5013 receives an instruction to interrupt the settlement of a transaction when the third operator is operated and input.

[0257] The interruption instruction means 5014 is a function that instructs the settlement device 40 to interrupt the settlement of a transaction in response to receiving a settlement interruption instruction for the transaction by the interruption reception means 5013. The interruption instruction means 5014 outputs a signal instructing the settlement device 40 to interrupt the settlement of the transaction.

[0258] The settlement device 40 further has functions as an interruption means 4015, a deletion means 4016, and a third settlement means 4017. The interruption means 4015 is a function that interrupts the processing related to the settlement of a transaction executed by the second settlement means 4014 in response to a settlement interruption instruction from the instruction device 50. When the interruption means 4015 receives a signal instructing to interrupt the settlement of a transaction before the payment of the price required for the settlement of the transaction is started, it interrupts the processing related to the settlement of the ongoing transaction.

[0259] The deletion means 4016 is a function that deletes the transaction file of the transaction whose settlement-related processing has been interrupted from the settlement device 40. The deletion means 4016 clears the third file area 4021 in response to the interruption of the processing related to the settlement of the transaction. Thus, the transaction file of the transaction whose settlement-related processing has been interrupted is deleted.

[0260] The third settlement means 4017 is a function that settles the transaction with the customer as the operator based on the information related to the transaction corrected by the correction means 3032 of the transaction processing device 30. The information related to the transaction corrected by the correction means 3032 is output from the transaction processing device 30 to the settlement device 40 via the holding server 10 as the data of the copy transaction file. The third settlement means 4017 settles the transaction corrected by the correction means 3032 based on the data of the copy transaction file acquired via the holding server 10.

[0261] Specifically, the third payment means 4017 settles the transaction with the customer in accordance with the payment method for the payment amount received by the first payment acceptance means 2013 or the third payment acceptance means 4013. The third payment means 4017 settles the transaction with the customer when the payment amount equivalent to the amount output by the second amount output means 4012 is paid by the payment method for the payment amount received by the first payment acceptance means 2013 or the third payment acceptance means 4013. For example, when cash is received as the payment method, the third payment means 4017 settles the transaction with the customer in cooperation with the automatic change dispenser 43. For example, when cashless payment is received as the payment method, the third payment means 4017 settles the transaction with the customer in cooperation with the cashless payment terminal 44.

[0262] Figure 49 is an example of an instruction screen SEb displayed on the touch panel 505 of the instruction device 50 in the settlement system 200. The instruction screen SEb is a screen on which an operator of the instruction device 50, that is, a store clerk who can be an instructor, can be selected. Similar to the instruction screen SEa in the settlement system 100, the instruction screen SEb includes a pull-down area AEa in which the names of each store clerk are displayed as a pull-down menu. In addition, the instruction screen SEb is provided with an interruption button BEb in addition to the call button BEa. The call button BEa and the interruption button BEb are software keys. The call button BEa is a first operator for receiving an instruction to transmit a transaction file to the settlement device 40. The interruption button BEb is a third operator for receiving an instruction to interrupt the settlement of a transaction. When an event occurs to abort the settlement performed by the settlement device 40, the store clerk standing in the space SP touches the interruption button BEb after confirming that his or her name is displayed in the pull-down area AEa. By this operation, the interruption reception means 5013 of the instruction device 50 functions to receive an instruction to interrupt the settlement of a transaction, and further, the interruption instruction means 5014 functions to output a third signal instructing the settlement device 40 to interrupt the settlement of the transaction. The third signal includes the employee code of the store clerk whose name is displayed in the pull-down area AEa, that is, the employee code stored in the employee memory 5031.

[0263] [Operation Explanation of Payment System 200] Even in the payment system 200, the processor 301 of the transaction processing device 30 executes first information processing according to the first business program. However, a part of the first information processing in the payment system 100 described with reference to FIGS. 11 to 14 is different from the processing described with reference to FIG. 14.

[0264] FIG. 50 is a flowchart showing the procedure when the payment in progress flag Fa is "1" in ACT126 (see FIG. 12) of the first information processing executed by the processor 301 of the transaction processing device 30 according to the first business program, and the hold flag Fb is "0" in ACT127 (see FIG. 12). That is, the procedure described with reference to FIG. 50 corresponds to the procedure described with reference to FIG. 14.

[0265] As is clear from the comparison between FIG. 50 and FIG. 14, in the payment system 200, the processing after obtaining the employee code from the employee memory 3026 in ACT147 is different. That is, the processor 301 creates a copy of the first transaction file stored in the first file area 3021 as ACT401. Then, the processor 301 stores the copied first transaction file, that is, the copy transaction file, in the copy file area 3027 as ACT402. Here, the processor 301 realizes the function as the copying means 3031 by executing the processes of ACT401 and ACT402.

[0266] Thereafter, the processor 301 executes the processes of ACT148 to ACT150. That is, the processor 301 outputs the first transaction file to the hold server 10 together with the employee code. The processor 301 sets the hold flag Fb to "1". The processor 301 clears the first file area 3021. Thus, the processor 301 ends the first information processing.

[0267] On the other hand, in the payment system 200, the second information processing and the third information processing executed by the processor 301 of the transaction processing device 30 according to the first business program are the same as those in the payment system 100. Also, the fourth information processing executed by the processor 101 of the hold server 10 according to the second business program, and the fifth information processing executed by the processor 401 of the payment device 40 according to the third business program are the same as those in the payment system 100.

[0268] Also in the payment system 200, the processor 401 of the payment device 40 executes the sixth information processing according to the third business program. However, the sixth information processing in the payment system 100 described with reference to FIG. 20 is partially different.

[0269] FIG. 51 is a flowchart showing the procedure of the sixth information processing executed by the processor 401 of the payment device 40 according to the third business program. As is clear from the comparison between FIG. 51 and FIG. 20, in the payment system 200, while the processor 401 waits for the payment method to be selected in ACT317, it checks whether there is an instruction to interrupt the payment as ACT501. Also, while the processor 401 waits for the payment of the price to start in ACT320, it checks whether there is an instruction to interrupt the payment as ACT502.

[0270] In ACT501 or ACT502, when the processor 401 receives a third signal instructing to interrupt the settlement of a transaction from the indicating device 50, the processor 401 determines that there is an instruction to interrupt the settlement. The processor 401 executes the processes of ACT503 to ACT505. That is, the processor 401 clears the third file area as ACT503. The processor 401 outputs the interrupt instruction, that is, the third signal, to the transaction processing device 30 as ACT504. The processor 401 sets the payment-in progress flag Fc to "0" as ACT505. Thus, the processor 401 ends the sixth information process. Here, the processor 401 of the settlement device 40 realizes the function as the deletion means 4016 by executing the process of ACT503. The processor 401 realizes the function as the interrupt means 4015 by executing the processes of ACT504 and ACT505.

[0271] FIG. 52 is a flowchart showing the main procedure of the seventh information process executed by the processor 301 of the transaction processing device 30 according to the first business program. The processor 301 is waiting for an interrupt instruction as ACT411.

[0272] In ACT504 of FIG. 51, the third signal output from the settlement device 40 is transmitted to the transaction processing device 30 via the hold server 10. As described above, the third signal includes an employee code. When the processor 301 of the transaction processing device 30 receives the third signal including the employee code stored in the employee memory 3026, the processor 301 determines that there is an interrupt instruction. The processor 301 proceeds to ACT412. The processor 301 checks whether the copy transaction file is stored in the copy file area 3027 as ACT412. If the copy transaction file is not stored in the copy file area 3027, it is a system error. The processor 301 ends the seventh information process as an error.

[0273] When the copy transaction file is stored in the copy file area 3027, the processor 301 proceeds to ACT413. The processor 301 checks whether the payment-in-progress flag Fa is "0" as ACT413. If the payment-in-progress flag Fa is "1", that is, when payment is being made in the transaction processing device 30, the processor 301 waits for the payment-in-progress flag Fa to become "0".

[0274] When the processor 301 confirms that the payment-in-progress flag Fa is "0", that is, payment is not being made in the transaction processing device 30, it proceeds to ACT414. The processor 301 acquires the copy transaction file from the copy file area 3027 as ACT414. Then, based on the data of the copy transaction file as ACT415, the processor 301 sets the screen of the first touch panel 32 to the correction screen SDb (see FIG. 53). Also, as ACT416, the processor 301 sets the screen of the second touch panel 33 to the clerk-operation-in-progress screen SCe (see FIG. 54).

[0275] FIG. 53 is an example of the correction screen SDb displayed on the first touch panel 32. The correction screen SDb is divided into a details area ADa and a total area ADb. The details area ADa is an area that lists, in a series of number order, the product name, purchase quantity, unit price, discount amount, and sales amount of the purchased products in a single transaction. The total area ADb is an area that displays the total purchase quantity and the total sales amount of the purchased products in a single transaction. Based on the product sales data of the copy transaction file acquired from the copy file area 3027, the processor 301 displays the product name, purchase quantity, unit price, discount amount, and sales amount of the purchased products in a single transaction in the details area ADa. Also, based on the product sales data, the processor 301 displays the total purchase quantity and the total sales amount of the purchased products in the total area ADb.

[0276] The correction screen SDb includes a correction completion button BDb. The correction completion button BDb is a software key. The correction completion button BDb is an operator for instructing the end of data correction.

[0277] FIG. 54 is an example of a screen SCe during clerk operation displayed on the second touch panel 33. The screen SCe during clerk operation is a screen that displays text for notifying the customer that the clerk is operating. Instead of the text, an image indicating that the clerk is operating may be displayed. Alternatively, the text and the image may be displayed together. The main point is that the customer should be able to be notified that the clerk is operating. When the screen SCe during clerk operation is displayed on the second touch panel 33, the second touch panel 33 becomes inoperable. That is, operation input from the second touch panel 33 is prohibited. Here, the processor 301 realizes the function as the prohibition means 3033 by executing the process of ACT416.

[0278] The clerk who has confirmed the correction screen SDb operates the first touch panel 32 to make corrections such as deleting purchased items, changing the purchase quantity or discount displayed in the details area ADa, etc. The clerk can also add and register purchased items by operating the keyboard 31 or the first touch panel 32. After finishing the correction, the clerk touches the correction completion button BDb. During such a correction operation, the screen of the second touch panel 33 is the screen SCe during clerk operation. Therefore, since the customer does not operate the second touch panel 33 when the clerk is operating the first touch panel 32, incorrect operations by the customer can be prevented.

[0279] Return to the description of FIG. 52. The processor 301, which sets the screen of the first touch panel 32 as the correction screen SDb and the screen of the second touch panel 33 as the in-store staff operation screen SCe, proceeds to ACT417. The processor 301 performs the correction process of the copy transaction file as ACT417. For example, when a deletion operation of a purchased item is performed, the processor 301 deletes the product sales data of the purchased item stored in the copy transaction file. For example, when a change operation of the purchase quantity or discount is performed, the processor 301 corrects the product sales data of the purchased item stored in the copy transaction file. For example, when an additional registration operation of a purchased item is performed, the processor 301 adds the product sales data of the purchased item to the copy transaction file. Further, the processor 301 corrects the total quantity and total amount of the purchased items stored in the copy transaction file. Here, the processor 301 of the transaction processing device 30 realizes the function as the correction means 3032 by performing the process of ACT417.

[0280] The processor 301 checks whether the correction completion button BDb has been input as ACT418. The processor 301 can execute the correction process until the correction completion button BDb is input. When the correction completion button BDb is input, the processor 301 proceeds to ACT419. The processor 301 outputs the corrected copy transaction file to the payment device 40 of the third signal source as ACT419.

[0281] The copy transaction file output from the transaction processing device 30 is transmitted to the payment device 40 of the third signal source via the hold server 10. The copy transaction file may be held in the hold server 10 and transmitted to the payment device 40 of the third signal source upon receiving an operation of the call button BEa displayed on the touch panel 505 of the instruction device 50.

[0282] The processor 401 of the settlement device 40 that has received the copy transaction file executes the processes of ACT312 to ACT329 in FIG. 51. Thus, the customer can operate the settlement device 40 by themselves to settle the corrected transaction. Here, the processor 401 realizes the function as the third settlement means 4017 by executing the processes of ACT312 to ACT329.

[0283] [Explanation of the operation of the settlement system 200] Next, the operation of the settlement system 200 will be described using the sequence diagrams in FIGS. 55 to 57. In FIG. 55, the store clerk starts a transaction with the first customer A. That is, the store clerk operates the input device 20 to register the purchased goods of customer A (Goods registration A). When the purchased goods are registered, the transaction processing device 30 creates a transaction file A. When the registration of the purchased goods is completed, the store clerk inputs the payment button BAe or the payment button BAh (Payment input A). The transaction processing device 30 determines whether the transaction can be settled. At this point, since the transaction can be settled, the transaction processing device 30 saves the transaction file A in the second file area 3022. The transaction processing device 30 does not create a copy of the transaction file A. Customer A moves to the installation location of the transaction processing device 30 and starts paying the price (Payment start A).

[0284] The store clerk starts a transaction with the second customer B. That is, the store clerk operates the input device 20 to register the purchased goods of customer B (Goods registration B). When the purchased goods are registered, the transaction processing device 30 creates a transaction file B. When the registration of the purchased goods is completed, the store clerk inputs the payment button BAe or the payment button BAh (Payment input B). The transaction processing device 30 determines whether the transaction can be settled. At this point, if customer A has not completed the payment, the transaction cannot be settled. The transaction processing device 30 transmits the transaction file B to the hold server 10. Also, the transaction processing device 30 creates a copy of the transaction file B and stores it in the copy file area 3027.

[0285] The hold server 10 stores the transaction file B. Since the guidance screen SDa is displayed on the first touch panel 32 of the transaction processing device 30 when the transaction file B is transmitted to the hold server 10, the store clerk inputs the call button BEa displayed on the touch panel 505 of the instruction device 50. When the call button BEa is input, a first signal is transmitted from the settlement device 40 to the hold server 10 in response to an instruction from the instruction device 50. In response to this first signal, the transaction file B is transmitted from the hold server 10 to the settlement device 40. The settlement device 40 stores the transaction file B in the third file area 4021. Customer B moves to the location where the settlement device 40 is installed and starts paying (payment start B).

[0286] The store clerk starts a transaction with the third customer C. That is, the store clerk operates the input device 20 to register the purchased items of customer C (item registration C). When the purchased items are registered, the transaction processing device 30 creates a transaction file C. After finishing the registration of the purchased items, the store clerk inputs the payment button BAe or the payment button BAh (payment input C). The transaction processing device 30 determines whether the transaction can be settled. At this point, if customer A has completed the payment, the transaction processing device 30 stores the transaction file C in the second file area 3022. Customer C moves to the location where the transaction processing device 30 is installed and starts paying (payment start C). At this time, a copy of the transaction file C is not created. Therefore, a copy file of the transaction file B is stored in the copy file area 3027.

[0287] The clerk starts a transaction with the fourth customer, D. That is, the clerk operates the input device 20 to register the purchased items of customer D (item registration D). When the purchased items are registered, the transaction processing device 30 creates a transaction file D. When the registration of the purchased items is completed, the clerk inputs the payment button BAe or the payment button BAh (payment input D). The transaction processing device 30 determines whether the transaction can be settled. At this point, if neither customer B nor customer C has completed the payment, information indicating non - payment is displayed on the touch panel 23 and the display 25 of the input device 20. Customer D waits until payment becomes possible.

[0288] Here, if customer C's payment is completed first, the transaction processing device 30 saves the transaction file D in the second file area 3022. Customer D moves to the location where the transaction processing device 30 is installed and starts the payment (payment start Da). Also at this time, a copy of the transaction file D is not created. Therefore, a copy file of the transaction file B is stored in the copy file area 3027.

[0289] On the other hand, as shown in FIG. 56, if customer B's payment is completed first, the transaction processing device 30 transmits the transaction file D to the hold server 10. Also, the transaction processing device 30 creates a copy of the transaction file D and stores it in the copy file area 3027.

[0290] The hold server 10 saves the transaction file D. The clerk inputs the call button BEa of the instruction screen SEa displayed on the touch panel 505 of the instruction device 50. When the call button BEa is input, a first signal is transmitted from the settlement device 40 to the hold server 10 in response to the instruction from the instruction device 50. In response to this first signal, the transaction file D is transmitted from the hold server 10 to the settlement device 40. The settlement device 40 saves the transaction file D in the third file area 4021. Customer D moves to the location where the settlement device 40 is installed and starts the payment (payment start Db).

[0291] Incidentally, before customer D starts paying, assume that the customer checks the details confirmation screen SFa displayed on the touch panel 41 and notices that, for example, product AAA is not discounted despite being a discount-eligible product. In this case, the customer verbally requests a correction from the store clerk standing in the space SP. The clerk who receives the request touches the interruption button BEb displayed on the instruction screen SEa of the instruction device 50. Then, as shown in FIG. 57, due to the action as the interruption instruction means 5014, a third signal is transmitted from the instruction device 50 to the settlement device 40.

[0292] Upon receiving the third signal, the settlement device 40 interrupts the processing related to the settlement of the ongoing transaction due to the action as the interruption means 4015. Also, the settlement device 40 clears the third file area 4021 due to the action as the deletion means 4016. Thus, the transaction file D is deleted. Further, the settlement device 40 outputs an interruption instruction to the transaction processing device 30. By this processing, the third signal is transmitted to the transaction processing device 30 via the hold server 10.

[0293] Upon receiving the third signal, the transaction processing device 30 acquires the transaction file stored in the copy file area 3027, that is, the copy transaction file Dn of customer D whose settlement was interrupted. Then, the transaction processing device 30 accepts the correction to the copy transaction file Dn due to the action as the correction means 3032. As a result, the corrected copy transaction file Dn is transmitted from the transaction processing device 30 to the settlement device 40 via the hold server 10.

[0294] The settlement device 40 stores the copy transaction file Dn in the third file area 4021. Customer D, who has been waiting near the settlement device 40 for the correction to finish, operates the settlement device 40 by himself / herself to resume the payment (payment resumption Dc).

[0295] Since the settlement system 200 operates as described above, the transaction file output to the settlement device 40 can be corrected by the operation of the store clerk without calling it back to the transaction processing device 30. Therefore, since a system configuration for calling back the transaction file to the transaction processing device 30 is unnecessary, the configuration can be simplified. In addition, since the store clerk can perform the correction work while staying in the space SP, it does not feel complicated and does not impose a large burden. Moreover, since the correction work can be performed only when another customer is not making a settlement in the transaction processing device 30, the settlement of other customers is not interrupted, and unnecessary trouble with other customers can be prevented in advance.

[0296] [Other Embodiments] The settlement system 200 of the second embodiment has a function as the copying means 3031 in the transaction processing device 30. The copying means 3031 copies the transaction file transmitted from the transaction processing device 30 to the hold server 10. For this reason, the hold server 10 may have a function as the copying means. Therefore, next, a settlement system 300 of a third embodiment in which the hold server 10 has a function as the copying means will be described with reference to FIGS. 58 to 62. In the following, the description will be specialized for parts different from the first and second embodiments.

[0297] FIG. 58 is a schematic diagram showing a main storage area formed in the auxiliary storage device 103 of the hold server 10. The hold server 10 forms an area as an employee-by-employee copy folder 1034 in addition to an area as an employee-by-employee folder 1033 in a part of the auxiliary storage device 103. The employee-by-employee copy folder 1034 stores copies of the transaction files stored separately for each employee in the employee-by-employee folder 1033 for each employee.

[0298] FIG. 59 is a schematic diagram showing a functional configuration of each of the transaction processing device 30, the settlement device 40, and the instruction device 50, excluding the functional configuration of each part of the settlement system 100. As is clear from a comparison between FIG. 59 and FIG. 48, in the settlement system 300, the reservation server 10 has a function as the copy means 1016. In relation to this, the transaction processing device 30 newly has a function as the copy acquisition means 3034. The copy acquisition means 3034 has a function of acquiring from the reservation server 10 the copy transaction file copied by the copy means 1016.

[0299] FIG. 60 is a flowchart showing the main procedure of the fourth information processing executed by the processor 101 of the reservation server 10 according to the second business program. As is clear from a comparison between FIG. 60 and FIG. 17, in the settlement system 300, the processing after the processor 101 stores the transaction file in the third file area 4021 in ACT207 is different. That is, the processor 101 creates a copy of the transaction file stored in the third file area 4021 as ACT601. Then, the processor 101 stores, as ACT602, the copied transaction file, that is, the copy transaction file, in the copy file area 4023. Thereafter, the processor 301 executes the processing of ACT208 to ACT226 in the same manner as described above.

[0300] FIG. 61 is a flowchart showing the main procedure of the eighth information processing executed by the processor 301 of the transaction processing device 30 according to the first business program. The processor 301 waits for an interrupt instruction as ACT611.

[0301] As described in the second embodiment, the third signal output from the settlement device 40 in FIG. 51 is transmitted to the transaction processing device 30 via the hold server 10. When the processor 301 receives the third signal including the employee code stored in the employee memory 3026, it determines that there is an interruption instruction. The processor 301 proceeds to ACT612. The processor 301 acquires the employee code from the employee memory 3026 as ACT612. Then the processor 301 transmits a copy request event to the hold server 10 as ACT613. The copy request event includes the employee code acquired from the employee memory 3026.

[0302] The processor 101 of the hold server 10 that has received the copy request event from the transaction processing device 30 acquires the copy transaction file stored in the employee-specific copy folder 1034 specified by the employee code included in the copy request event. Then the processor 101 transmits the copy transaction file to the transaction processing device 30 that is the source of the copy request event.

[0303] The processor 301 of the transaction processing device 30 that has transmitted the copy request event waits for the copy transaction file as ACT614. For example, if the copy transaction file cannot be acquired within a certain period of time, a system error has occurred. The processor 301 ends the eighth information processing as an error.

[0304] When the processor 301 acquires the copy transaction file from the hold server 10 in ACT614, it proceeds to ACT615. The processor 301 stores the copy transaction file in the copy file area 3027 as ACT615. Here, the processor 301 realizes the function as the copy acquisition means 3034 by executing the processing of ACT612 to ACT615.

[0305] The processor 301 that stores the copy transaction file in the copy file area 3027 executes processing equivalent to that of ACT415 to ACT419 in the second embodiment described with reference to FIG. 52 as ACT616 to ACT620. That is, based on the data of the copy transaction file, the processor 301 sets the screen of the first touch panel 32 as the correction screen SDb. Further, the processor 301 sets the screen of the second touch panel 33 as the screen SCe during clerk operation. Then, the processor 301 performs a correction process on the copy transaction file. When the correction end button BDb is input during this correction process, the processor 301 outputs the corrected copy transaction file to the settlement device 40 that is the third signal transmission source. Thus, the customer can operate the settlement device 40 by himself / herself to settle the corrected transaction.

[0306] [Explanation of the operation of the settlement system 300] Next, the operation of the settlement system 300 will be described with reference to the sequence diagram of FIG. 62. FIG. 62 shows a state where the transaction file D is transmitted to the settlement device 40 and the customer D can perform settlement at the settlement device 40. Here, when the customer D requests correction from the clerk standing in the space SP and the clerk who has received the request touches the interruption button BEb displayed on the instruction screen SEa of the instruction device 50, a third signal is transmitted from the instruction device 50 to the settlement device 40 by the action as the interruption instruction means 5014.

[0307] Upon receiving the third signal, the settlement device 40 interrupts the processing related to the settlement of the ongoing transaction by the action as the interruption means 4015. Further, the settlement device 40 clears the third file area 4021 by the action as the deletion means 4016. Thus, the transaction file D is deleted. Also, the settlement device 40 outputs an interruption instruction to the transaction processing device 30. By this processing, the third signal is transmitted to the transaction processing device 30 via the hold server 10.

[0308] Upon receiving the third signal, the transaction processing device 30 sends a fourth signal, i.e., a signal for a copy request event, to the reservation server 10. Upon receiving the fourth signal, the reservation server 10 acquires the copy transaction file Dn from the employee-specific copy folder 1034. Then, the reservation server 10 sends the acquired copy transaction file Dn to the transaction processing device 30. The transaction processing device 30 stores the copy transaction file Dn in the copy file area 3027. Then, the transaction processing device 30, acting as the correction means 3032, accepts corrections to the transaction file Dn. As a result, the corrected transaction file Dn is sent from the transaction processing device 30 to the settlement device 40 via the reservation server 10.

[0309] The settlement device 40 stores the transaction file Dn in the third file area 4021. Customer D, who has been waiting near the settlement device 40 for the correction to finish, operates the settlement device 40 himself / herself to resume the payment (payment resumption Dc).

[0310] Since the settlement system 300 operates as described above, it can achieve the same operational effects as the settlement system 200.

[0311] In the second embodiment, when the reservation cancellation button BDa on the guidance screen SDa is input, an example is given where the transaction file reserved in the reservation server 10 is returned to the transaction processing device 30, and the transaction processing device 30 settles the transaction based on the data of the transaction file. As described in the second embodiment, a copy of the transaction file reserved in the reservation server 10 is stored in the copy file area 3027 of the transaction processing device 30. Therefore, when the reservation cancellation button BDa is input, instead of returning the transaction file reserved in the reservation server 10 to the transaction processing device 30, the transaction processing device 30 may settle the transaction using the copy transaction file stored in the copy file area 3027. By adopting such a configuration, the effort of returning the transaction file reserved in the reservation server 10 to the transaction processing device 30 becomes unnecessary.

[0312] The configurations of the payment systems 100, 200, and 300 are not limited to those shown in FIG. 1. FIG. 63 illustrates another payment system 400. In the payment system 400, an input device 20 and a transaction processing device 30 are arranged in one payment lane L, and a payment device 40 and an instruction device 50 are shared by two adjacent payment lanes L. In this payment system 400, a space SP for the store clerk is provided between two adjacent payment lanes L. Then, the payment device 40 and the instruction device 50 are arranged between the transaction processing device 30 of one payment lane L and the transaction processing device 30 of the other payment lane L. With such an arrangement, a customer in one payment lane L can self-operate the transaction processing device 30 of that payment lane L or the shared payment device 40 to settle the transaction. Similarly, a customer in the other payment lane L can self-operate the transaction processing device 30 of that payment lane L or the shared payment device 40 to settle the transaction.

[0313] Note that by sharing the instruction device 50, it is necessary to change the layout of the instruction screen displayed on the touch panel 505. FIG. 64 is an example of the instruction screen SEc of the instruction device 50 in the payment system 400. The instruction screen SEc divides the screen of the touch panel 505 into two parts left and right. On the left side, the lane number of the lane L located on the left side facing the instruction screen SEc, for example, "001", a pull-down area AEaa, a call button BEaa, and an interrupt button BEba are arranged. On the right side, the lane number of the lane L located on the right side facing the instruction screen SEc, for example, "002", a pull-down area AEab, a call button BEab, and an interrupt button BEbb are arranged.

[0314] By setting the screen of the touch panel 505 of the instruction device 50 shared by two adjacent lanes as the instruction screen SEc, the store clerk X who serves customers in the lane with lane number "001" selects his / her name in the pull-down area AEaa. The store clerk Y who serves customers in the lane with lane number "002" selects his / her name in the pull-down area AEab. Through such operations, the employee code of store clerk X is stored in the employee memory 5031 of the instruction device 50 in association with the lane number "001". Also, the employee code of store clerk Y is stored in association with the lane number "002".

[0315] In addition, the call button BEaa and the interruption button BEba become valid at the timing when the transaction file of the transaction processed in the lane with lane number "001" is placed on hold in the hold server 10. Therefore, when store clerk X touches the call button BEaa, the transaction file held in the employee-specific folder 1033 with the employee code of store clerk X set is output from the hold server 10 to the settlement device 40 on the condition that the settlement device 40 is available. Thus, the customer of the transaction processed in the lane with lane number "001" can settle the transaction at the settlement device 40. Also, when store clerk X touches the interruption button BEba, correction processing is executed based on the copy file of the transaction file output from the hold server 10 to the settlement device 40 on the condition that the transaction processing device 30 in the lane with lane number "001" is available.

[0316] Similarly, the call button BEab and the interruption button BEbb become effective at the timing when the transaction file processed in the lane with the lane number "002" is placed on hold in the hold server 10. Therefore, when the store clerk Y touches the call button BEab, on the condition that the settlement device 40 is available, the transaction file held in the employee-specific folder 1033 with the employee code of the store clerk Y set is output from the hold server 10 to the settlement device 40. Thus, the customer of the transaction processed in the lane with the lane number "002" can settle the transaction with the settlement device 40. Also, when the store clerk Y touches the interruption button BEbb, on the condition that the transaction processing device 30 in the lane with the lane number "002" is available, a correction process is executed based on the copy file of the transaction file output from the hold server 10 to the settlement device 40.

[0317] In the above embodiment, the input device 20 is provided with the function as the first payment reception means 2013, but this function may be omitted. When omitted, the processing steps of ACT111 shown in FIG. 11 and the processing steps of ACT121 to ACT124 shown in FIG. 12 are eliminated. That is, when the payment button BAe on the subtotal screen is input in ACT112 of FIG. 11, the processor 301 proceeds to ACT126 of FIG. 12. Then, when the payment-in progress flag Fa is "0", it proceeds to ACT131 of FIG. 13, and when the payment-in progress flag Fa is "1" and the on-hold flag Fb is "0", it proceeds to ACT141 of FIG. 14.

[0318] In the above embodiment, it has been described that when the call button BEa of the instruction device 50 is input, upon receiving the instruction from the instruction device 50, a first signal is output from the settlement device 40 to the hold server 10. In this regard, when the call button BEa of the instruction device 50 is input, it may be assumed that a first signal is directly output from the instruction device 50 to the hold server 10.

[0319] In the above embodiment, when the instruction device 50 receives a signal indicating the activation of an instruction from the hold server 10, the call button BEa is set to an input-enabled state. In this regard, the instruction device 50 may always be in a state where the call button BEa can be input. That is, regardless of whether the hold server 10 is holding a transaction file, the call button BEa may be input-enabled.

[0320] In the above embodiment, the case where a tablet terminal is used as the instruction device 50 is exemplified. The instruction device 50 is not limited to a tablet terminal. For example, a touch panel for store clerk operation is provided separately from the customer operation touch panel 41 as the settlement device 40. The touch panel for store clerk operation is provided at a location where a store clerk standing in the space SP can perform a touch operation. The processor 401 of the settlement device 40 controls the touch panel for store clerk operation in the same manner as the customer operation touch panel 41. Specifically, the processor 401 sets the screen of the touch panel for store clerk operation as the instruction screen SEa. Then, when the call button BEa on the instruction screen SEa is input, the processor 401 outputs a signal instructing to output information related to the transaction to the settlement device 40 to the hold server 10 via the settlement device 40. That is, the touch panel for store clerk operation controlled by the processor 401 functions as the instruction device 50. By adopting such a configuration, a touch panel can be applied as the instruction device 50 instead of a tablet terminal, so that the system cost can be reduced.

[0321] In addition, although some embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the gist of the invention. These embodiments and their modifications are included in the scope of the invention and are included in the invention described in the claims and its equivalent scope.
