Description

Technical Field

[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 employee called a checker and a transaction processing device operated by a store employee 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 merchandise sales data of purchased goods based on the information input via the input device and settling transactions with customers. In the two-person payment system, since the input device and the transaction processing device are separated, 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 have customers perform operations related to receiving payments required for transaction settlements. Even in the two-person payment system, customers are made to perform operations related to receiving payments for the transaction processing device. By doing so, the store employee in charge of the cashier becomes unnecessary, so labor costs can be reduced.

Mode for Carrying Out the Invention

[0008] Hereinafter, the embodiments will be described with reference to the drawings. <Basic Configuration and Operation> First, the basic configuration and operation of the settlement system according to the embodiment will be described with reference to FIGS. 1 to 43.

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

[0010] The settlement system 100 connects the hold server 10, the transaction processing device 30 and the 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 the 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] FIG. 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. FIG. 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, which is called a cash register or the like, 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 table 82 for placing the purchased products before registration, and the downstream side is used as a table 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 so 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 so 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 so 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. The 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 the 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 the customer.

[0018] With such an arrangement of devices, the 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, the customer standing in the passage PA can confirm on the spot the information displayed on the second touch panel 33, for example, information related to the payment of the price. And the customer who pays the price in cash can put the cash into the coin dispenser 35 while standing in the passage PA and collect the change paid out. The 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 cashless. When the payment of the price is completed, a receipt is issued from the printer 34, so the customer can receive the receipt on the spot.

[0019] In this way, the transaction processing device 30 functions as a self-type settlement device that allows the customer to perform the operations related to the payment of the price by himself. 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-type payment device that allows customers to perform operations related to payment of the price themselves. The payment device 40 is used by customers who, for example, cannot pay the price with the transaction processing device 30 because the transaction processing device 30 is in use. 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 currency 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 surface 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 price. Then, a customer who pays the 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 price by cashless payment can operate the cashless payment terminal 44 on the spot to pay the price cashlessly. When the payment of the 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 also be referred to as a cash register, 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 pointing 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 pointing device 50 is operated by a store clerk. Therefore, the retail store installs the pointing device 50 at a position where it is easy for the store clerk in the space SP to operate. The installation position of the pointing device 50 is not particularly limited. FIG. 2 shows an example in which the pointing 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.

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 displayed on the first line of the details area ABa, the processor 301 sequentially shifts the data after the first line to the lines after 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. The processor 301 checks whether the next purchased product has been registered as ACT107. If the next purchased product has not been registered, the processor 301 proceeds to ACT108. The processor 301 checks whether the subtotal button BAa has been input as ACT108. 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] Figure 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 items and the total of the sales amounts 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 of the purchase price after the registration of the purchased items is completed. The return button BAf is an operator for instructing a return to the registration of the purchased items.

[0114] Figure 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 items, the deposited amount, and the balance are displayed. At this point, since no deposited amount has occurred, the deposited amount is 0 yen, and the balance is the amount obtained by subtracting the deposited 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 hours when the store is crowded, 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. When confirming the payment method with the customer, the store clerk touches the payment method selection button BAd. When not confirming 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] When the return button BAf is input by a touch operation in the standby states of ACT110 to ACT112, the processor 301 proceeds to ACT113. The processor 301 returns the screens of the touch panel 23 and the display 25 as ACT113 to the immediately previous 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] When the payment method selection button BAd is input by a touch operation in the standby states of ACT110 to ACT112, the processor 301 proceeds to ACT121 in FIG. 12. The processor 301 sets the screen of the touch panel 23 as ACT121 to 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 ticket 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 ticket button is a button for instructing payment with a gift ticket. When the gift ticket button is input, a screen for selecting the type of gift ticket such as a merchandise voucher is displayed. The cash button, the credit button, the electronic money button, the code settlement button, and the gift ticket 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 for 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 by credit card, the store clerk touches the credit button in the selection button group BAg. Similarly, when the customer wishes to pay by 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 acquires the payment code for 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, and code settlement payment. For example, when the cash button is touched, the processor 301 acquires the payment code corresponding to cash payment, for example, "11". For example, when the credit button is touched, the processor 301 acquires 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 acquired 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 is 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 a 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 transaction processing device 30 is in a state where payment for the price is being made, 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 payment for the price is impossible. The processor 301 also displays a text TXa (see FIG. 28) on the subtotal screen SBb of the display 25 to instruct to wait because payment for the price is impossible.

[0130] FIG. 26 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 payment for the price becomes possible.

[0132] The processor 301 that notifies 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, when the payment-in-progress flag Fa has been rewritten to "0", the processor 301 proceeds to ACT131 in FIG. 13. When 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, when 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) notifying that payment can be made in the transaction processing device 30 on the subtotal screen SAb or the payment screen SAd of the touch panel 23. The processor 301 also displays a text TXb (see FIG. 30) for instructing that payment can be made on the subtotal screen SBb of the display 25.

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

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

[0137] The processor 301 that has notified that the payment can be made using the touch panel 23 and the display 25 proceeds to ACT132. The processor 301 checks whether the payment code has been acquired as ACT132. If the payment code has not been acquired, 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". The processor 301 also clears, as ACT139, the first file area 3021. Thus, 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 hold 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. The processor 301 also 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 hold event to the hold server 10 via the communication interface 305. The hold event is an event requesting the hold of a transaction file. The hold event includes the transaction processor ID of the transaction processor 30.

[0141] As will be described in detail 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 finishes 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 can be paid by the transaction processing device 30. Also, the first transaction file is saved in the second file area 3022, and the payment flag Fa becomes "1". Therefore, self-service 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 paying the price.

[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 apparatus 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 the second information processing executed by the processor 301 of the transaction processing apparatus 30 according to the first business program. The processor 301 executes the second information processing in parallel with the above-described first information processing.

[0149] The processor 301 waits for the payment-in-progress flag Fa to become "1" as ACT161. In ACT138 of the first information processing, 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 processing, 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 of 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 by 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 acquires the payment code of the selected payment method in the same way as the processing of ACT123 of the first information processing.

[0153] On the other hand, in ACT162, when the payment status ST is "20", 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] After finishing the processing of ACT165 or ACT166, the processor 301 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] The customer who has confirmed the payment notification screen SCb pays the amount due by the payment method they have selected. For example, a customer who has selected cash payment inserts cash into the automatic change machine 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 due as ACT168. For example, when cash payment is selected, the processor 301 waits for cash to be inserted into the automatic change machine 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 due starts, the processor 301 proceeds to ACT169. The processor 301 issues 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 in the transaction processing device 30. The processor 301 that has issued 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 is 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 the 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 that sets 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 the settlement process of the transaction based on the payment code as ACT172. That is, when the payment code is a cash payment code, the processor 301 executes the settlement process of 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 the settlement process of 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 the settlement process of 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 the settlement process of 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 names, prices, quantities, and amounts 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 saved on the POS server. It may be saved on 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 button BAe on the subtotal screen SAb or the payment button BAh on the payment screen SAd is input while the payment in progress flag Fa is "0", 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 the transaction processing device 30 is the payee, 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 checked 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 was making 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 who has determined 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 a pending event receives a permission response, it outputs the transaction file (first transaction file) stored in the first file area to the pending 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 it receives the transaction file 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 pending 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 the 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 and selects his or her own name from the pull-down menu. By such an operation, the employee code of the said 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 time thereafter.

[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, a first signal is output from the settlement device 40 upon receiving an instruction from the instruction device 50. The first signal output from the settlement device 40 is transmitted to the hold server 10 via the settlement device 40. 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 has output 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 for the call button BEa of the instruction screen SEa to be input or the hold cancellation button BDa of the guidance screen SDa to be input in ACT211 and ACT212.

[0182] In the standby states of ACT211 and ACT212, when receiving the instruction from the instruction device 50 and 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. As ACT213, the processor 101 refers to the lane table 1032 and acquires the settlement device ID described in the column Cc of the same row as the transaction processing device ID. Then, as ACT214, the processor 101 transmits an execution event to the settlement device 40 identified by that settlement device ID. The execution event is an event that requests the execution of the settlement process.

[0183] Details will be described later with reference to FIG. 19, but from the settlement device 40 that has received the execution event, a permission response or a negative response is returned. The permission response is returned when the transaction can be settled in the settlement device 40. The negative response is returned when the transaction cannot be settled in the settlement device 40.

[0184] The processor 101 that has transmitted the execution event proceeds to ACT215. As ACT215, the processor 101 checks whether a permission response has been received. If a permission response has been received, the processor 101 proceeds to ACT216. As ACT216, the processor 101 acquires the employee code from the first signal. 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, as ACT217, the employee-specific folder 1033 corresponding to that employee code. Then, as ACT218, the processor 101 transmits the third transaction file held in the selected employee-specific folder 1033 to the settlement device 40. That is, the processor 101 transmits the third transaction file stored in the employee-specific folder 1033 corresponding to 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 sent the transaction file proceeds to ACT219. The processor 101 sends a cancellation notice event to the transaction processing device 30 which is the source of the third transaction file as ACT219. That is, the processor 101 sends a cancellation notice event to the transaction processing device 30 identified by the transaction processing device ID obtained 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 sent 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 obtains the employee code from the second signal as ACT221. Note that the processor 101 may also obtain the employee code described in the column Ce of the same row as the transaction processing device ID obtained in the process of ACT204 by referring to the lane table 1032.

[0189] The processor 101 that has obtained the employee code selects the employee - specific folder 1033 of that employee code as ACT222. Then the processor 101 sends 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 sends 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 obtained 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 finishes the fourth information process.

[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 transmitted 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 receiving the error cancellation signal 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 finished the settlement yet 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 finish the settlement and then input the call button BEa. Alternatively, when the customer who was performing the settlement with the transaction processing device 30 finishes 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 suspension 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 suspended 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] In this way, the transaction file (the first transaction file), that is, the information related to the transaction output from the transaction processing device 30 to the suspension server 10, is stored, that is, suspended, for each clerk standing in the settlement lane L in the employee-specific folder 1033 in the suspension server 10. Then, when the clerk inputs the call button BEa of the instruction device 50, an execution event is transmitted from the instruction device 50 to the settlement device 40. In response to this execution event, the transaction file (the third transaction file) suspended in the suspension server 10 is transmitted to the settlement device 40. At this time, a release notice event is transmitted from the suspension server 10 to the transaction processing device 30 of the same settlement lane L. On the other hand, when the clerk inputs the suspension release button BDa of the transaction processing device 30, a suspension release event is transmitted from the transaction processing device 30 to the settlement device 40. In response to this suspension release event, the transaction file (the third transaction file) suspended in the suspension 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 pay the price 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 pays the price.

[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 flag Fa as ACT187. Here, if the payment flag Fa is "1", that is, when 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 flag Fa is "0" in ACT187, that is, when 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 has saved 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) that notifies that payment for the transaction by the transaction processing device 30 is possible 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 for the amount is possible on the subtotal screen SBb of the display 25.

[0206] In this way, the processor 301 that has notified that payment for the transaction by the transaction processing device 30 is possible 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 of 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 in the state where the transaction file is put 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, when the payment-in-progress flag Fc is "1", that is, when the previous customer is still executing 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 other hand, when the payment-in-progress flag Fc is "0" in ACT302, that is, when the customer is not performing 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 finishes 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 made a 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 taking-in 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 aforementioned fifth information processing.

[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 shows an example of a detail confirmation screen SFa displayed on the touch panel 41. The detail 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 detail 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 product are displayed on the detail 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 detail 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 as a payment method selection screen SFb (see FIG. 40) as ACT316.

[0222] FIG. 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 in which 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 by 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 in which 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, which 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, obtains the payment code of the selected payment method in the same way as the processing of ACT123 of the first information processing.

[0225] The processor 401 that has completed the processing of ACT315 or ACT318 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 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 using 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 data of the electronic money medium 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 assigns 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 assigned 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] Figure 42 is an example of the in - payment screen SFd displayed on the touch panel 41. Figure 42 shows the in - payment screen SFd when the payment code for cash payment is obtained by the process of ACT315 or ACT318. The in - payment screen SFd is a screen obtained by adding the accounting button BFd to the payment notification screen SCb. In the in - payment 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 in - payment screen SFd, and the customer can call the clerk.

[0231] The processor 401 with the screen of the touch panel 41 as the in - payment 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 the 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 the 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 the 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 the 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 the 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 explanations 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 ACT236. 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, as ACT327, the data of the fifth transaction file stored in the third transaction file 4021, 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 in the POS server. It may be stored in 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 and 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 processing.

[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 to the details 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 to the payment notification screen SFc. In addition, 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 to the payment notification screen SFc. After that, when the payment is started, the processor 401 sets the screen of the touch panel 41 to the payment in progress screen SFd. Also, the processor 401 issues 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 to the payment completed 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 sends 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 sent 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 instruction device 50. When the call button BEa is input, a first signal is sent 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 B is sent 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 A 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 amount due, 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 making 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 amount due, 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 making the payment (payment start Da).

[0243] On the other hand, as shown in FIG. 45, when the payment of 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 price (payment start Db).

[0244] On the other hand, as shown in FIG. 46, if the payment of 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 price (payment start Dc).

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

[0246] <Configuration and operation related to the instruction giver change process of the instruction device> Next, the configuration and operation related to the instructing person change process in the settlement system according to the embodiment will be described with reference to FIGS. 47 to 49. The instructing person change process is a process of changing the instructing authority of the instruction device 50 by changing the employee code stored in the employee memory 5031 of the instruction device 50.

[0247] Hereinafter, the transaction file or transaction information held in the holding server 10 will be referred to as "held data". Also, a store clerk who operates the instruction device 50 to instruct the calling of held data will be referred to as an "instructor", and will be appropriately distinguished from the operator of the input device 20. The employee code of the instructor may be read as instructor identification information.

[0248] [Explanation of Functional Configuration Related to Instructor Change Process] FIG. 47 is a schematic diagram showing the functional configuration related to the instructing person change process that the holding server and the instruction device of the settlement system according to the embodiment respectively have.

[0249] As a functional configuration related to the instructing person change process, the instruction device 50 has functions as an instructing person acquisition means 5013, an inquiry means 5014, and a determination means 5015. The holding server 10 has a function as a response means 1016 as a functional configuration related to the instructing person change process.

[0250] The instructing person acquisition means 5013 is a function of acquiring the employee code of a store clerk who is a candidate for the instructor. The instructor may be the same person as the operator of the input device 20 or a different person. The instructing person acquisition means 5013 acquires the employee code based on the input of a store clerk who is a candidate for the instructor.

[0251] The inquiry means 5014 has a function of inquiring the reservation server 10 about the existence of reservation data stored in association with the employee code of the current instructing person. The inquiry means 5014 reads out the employee code of the store employee stored as the instructing person in the employee memory 5031 of the instruction device 50 in response to the acquisition of the employee code of the candidate store employee as the instructing person. The inquiry means 5014 inquires the reservation server 10 as to whether the reservation server 10 holds reservation data stored in association with the employee code read from the employee memory 5031.

[0252] Hereinafter, the candidate store employee as the instructing person is also referred to as the "new instructing person". The store employee corresponding to the employee code stored in the employee memory 5031 is also referred to as the "current instructing person". The new instructing person is a store employee who is scheduled to operate the instruction device 50 in place of the current instructing person and is different from the current instructing person. That is, the instructing person acquisition means 5013 acquires the employee code of the new instructing person while the employee code of the current instructing person is stored in the employee memory 5031. The inquiry means 5014 inquires the reservation server 10 about the existence of reservation data stored in association with the employee code of the current instructing person in response to the acquisition of the employee code of the new supporter.

[0253] The determination means 5015 has a function of determining whether the instructing person of the instruction device 50 can be changed based on the inquiry result received from the reservation server 10 in response to the inquiry by the inquiry means 5014. When there is reservation data to be inquired about, the determination means 5015 rejects the change from the current instructing person to the new instructing person. When there is no reservation data to be inquired about, the determination means 5015 permits the change from the current instructing person to the new instructing person.

[0254] The response means 1016 has a function of responding to the inquiry by the inquiry means 5014. Specifically, the response means 1016 responds to the inquiry means 5014 with information indicating whether there is reservation data to be inquired about, that is, reservation data stored in association with the employee code of the current instructing person, as the inquiry result.

[0255] [Operation Explanation Regarding Instructing Person Change Processing] FIG. 48 is a sequence diagram showing an example of the instructing person change process in the settlement system according to the embodiment. FIG. 48 shows the cooperation operation between the instructing device 50 and the hold server 10 when changing the instructing authority of the instructing device 50 from the current instructing person to a new instructing person.

[0256] First, along with the change of the instructing person, the new instructing person inputs their employee code as their instructing person identification information to the instructing device 50. Accordingly, the processor 501 acquires the instructing person identification information of the new instructing person (ACT331).

[0257] There are, for example, three methods for acquiring the instructing person identification information. FIG. 49 is an example of an instruction screen displayed on the touch panel of the instructing device. As shown in FIG. 49, the instruction screen SEa further includes a numeric keypad icon BEb and a camera icon BEc in addition to the pull-down area AEa and the call button BEa. The numeric keypad icon BEb and the camera icon BEc are software keys.

[0258] The first method is to operate the pull-down area AEa to select one's own name from the pull-down menu as described with reference to FIG. 36. The second method is to input the employee code using the numeric keypad, which is a software key displayed by clicking the numeric keypad icon AEb. The third method is to input the barcode indicating the employee code from the camera 506 activated by clicking the camera icon AEc.

[0259] In response to the acquisition of the employee code of the new instructing person, the processor 501 transmits the employee code of the current instructing person to the hold server, thereby inquiring of the hold server 10 about the existence of hold data associated with the employee code of the current instructing person (ACT332). In other words, when the instructing person identification information of a new instructing person different from the instructing person identification information of the current instructing person is acquired, the processor 501 inquires of the hold server 10 about the existence of hold data stored in association with the operator identification information that matches the instructing person identification information of the current instructing person.

[0260] In response to an inquiry from the indicating device 50, the processor 101 responds to the indicating device 50 as the result of the inquiry regarding the presence or absence of pending data stored in association with the employee code of the current indicator.

[0261] Specifically, when there is pending data stored in association with the employee code of the current indicator (when there is pending data in Fig. 48), the processor 101 transmits a notification indicating that there is pending data to be queried to the indicating device 50 (ACT333).

[0262] Upon receiving the notification that there is pending data to be queried, the processor 501 determines to include the employee code of the current indicator in the first signal when the call button BEa is input later, and rejects the change of the instruction authority from the current indicator to the new indicator (ACT334). That is, the processor 501 displays the name of the current indicator instead of the new indicator in the pull-down area AEa of the instruction screen SEa. In addition, the processor 501 may further display a text indicating that the change of the instruction authority from the current indicator to the new indicator has been rejected on the instruction screen SEa.

[0263] On the other hand, when there is no pending data stored in association with the employee code of the current indicator (when there is no pending data in Fig. 48), the processor 101 transmits a notification indicating that there is no pending data to be queried to the indicating device 50 (ACT335).

[0264] Upon receiving the notification that there is no pending data to be queried, the processor 501 determines to include the employee code of the new indicator in the first signal when the call button BEa is input later, and changes the instruction authority from the current indicator to the new indicator (ACT336). That is, the processor 501 displays the name of the new indicator instead of the current indicator in the pull-down area AEa of the instruction screen SEa, and overwrites the employee code stored in the employee memory 5031 from the current indicator to the new indicator. In addition, the processor 501 may further display a text indicating that the change of the instruction authority from the current indicator to the new indicator has been permitted on the instruction screen SEa.

[0265] Thus, the instructor change process ends.

[0266] Here, the processor 501 realizes the function as the instructor acquisition means 5013 by executing the process of ACT331 in cooperation with the touch panel 51 and the camera 52. The processor 501 realizes the function as the inquiry means 5014 by executing the process of ACT332. The processor 101 realizes the function as the response means 1016 by executing the processes of ACT333 and ACT335. The processor 501 realizes the function as the determination means 5015 by executing the processes of ACT334 and ACT336.

[0267] [Explanation of the operation related to the instructor change process] According to the embodiment, the instructor acquisition means 5013 acquires instructor identification information for identifying an instructor. The instruction means 5012 outputs an instruction to output the hold data held in the hold server 10 to the settlement device 40 to the hold server 10 together with the instructor identification information acquired by the instructor acquisition means 5013. Thereby, the hold server 10 can specify the hold data to be output to the settlement device 40 according to the instruction from the instruction means 5012 based on the instructor identification information. Therefore, the settlement process can be performed more flexibly.

[0268] Supplementary, when the instruction device 50 does not output the instructor identification information to the hold server 10, as a method for the hold server 10 to identify the hold data, there is a method of referring to the lane table 1032. However, in this case, the settlement device 40 can only output the hold data stored in association with the employee code corresponding to its own settlement device ID in the lane table 1032. That is, the settlement device 40 cannot guide the customers in other lanes. According to the embodiment, the hold server 10 specifies the hold data to be output to the settlement device 40 according to the instruction from the instruction means 5012 based on the instructor identification information. Thereby, when the instruction device 50 is operated by an employee in another lane, it becomes possible to guide the customers in other lanes to the settlement device 40. Therefore, the settlement process can be performed more flexibly.

[0269] Further, when the inquirer 5014 obtains the instructor identification information of the new instructor by the instructor acquirer 5013, it inquires whether the first hold data associated with the operator identification information that matches the instructor identification information of the current instructor is held in the hold server 10. Based on the result of the inquiry received from the hold server 10, the determination means 5015 determines which of the instructor identification information of the current instructor and the new instructor is to be output together with the subsequent instructions by the instruction means 5012. Specifically, when the first hold data is held in the hold server 10, the determination means 5015 determines that the instructor identification information of the current instructor is to be output together with the subsequent instructions. When the first hold data is not held in the hold server 10, the determination means 5015 determines that the instructor identification information of the new instructor is to be output together with the subsequent instructions. Thereby, it is possible to avoid a situation where an employee changes while a transaction file for which the settlement process has not been completed is held in the hold server 10. In other words, it is possible to avoid a situation where an employee ends their work while the transaction file that the employee themselves caused to be held in the hold server 10 remains. For this reason, it is possible to avoid an operation error such as a customer occurring who cannot execute the settlement process on either the transaction processing device 30 or the settlement device 40.

[0270] <Modification Example> In the above-described embodiment, various modifications can be applied.

[0271] In the above-described embodiment, the case where the instruction device 50 rejects the change of the instruction authority from the current instructor to the new instructor when there is hold data to be inquired about has been described, but it is not limited to this. For example, even when there is hold data to be inquired about, the instruction device 50 may permit the change of the instruction authority from the current instructor to the new instructor.

[0272] [Explanation of Functional Configuration Related to Instructor Change Processing] FIG. 50 is a schematic diagram showing the functional configuration related to the instructor change processing of the hold server and the instruction device of the settlement system according to the modification example. FIG. 50 corresponds to FIG. 47 in the embodiment.

[0273] In the modified example, as a functional configuration related to the instructor change process, the instruction device 50 has functions as an instructor acquisition means 5013, an inquiry means 5016, and a determination means 5017. The reservation server 10 has functions as a handover means 1017 and a response means 1018 as a functional configuration related to the instructor change process. The functional configuration of the instructor acquisition means 5013 in the modified example is equivalent to the functional configuration of the instructor acquisition means 5013 in the embodiment.

[0274] The inquiry means 5016 is a function of inquiring the reservation server 10 about the presence or absence of reservation data (handover data) to be handed over from the current instructor to the new instructor. The inquiry means 5016 reads out the employee code of the current instructor from the employee memory 5031 in response to the acquisition of the employee code of the new instructor. Then, the inquiry means 5016 inquires the reservation server 10 about the presence or absence of handover data by outputting the employee code of the new instructor and the employee code of the current instructor to the reservation server 10.

[0275] The determination means 5017 is a function of determining whether the instructor of the instruction device 50 can be changed in response to the acquisition of the employee code of the new instructor. The determination means 5017 permits the change from the current instructor to the new instructor regardless of the inquiry result.

[0276] The handover means 1017 is a function of changing the employee code associated with the reservation data in response to the inquiry by the inquiry means 5016. When there is reservation data stored in association with the employee code of the current instructor received from the inquiry means 5016, the handover means 1017 recognizes that the reservation data is handover data and re-associates it with the employee code of the new instructor. Specifically, the handover means 1017 re-stores the reservation data stored in the employee-specific folder 1033 corresponding to the current instructor in the employee-specific folder 1033 corresponding to the new instructor. Note that when there is no reservation data stored in association with the employee code of the current instructor received from the inquiry means 5016, the handover means 1017 recognizes that there is no handover data and does not perform the handover process of the reservation data.

[0277] The response means 1018 has a function of responding to the inquiry by the inquiry means 5016. Specifically, when there is handover data, after the handover process of the suspended data by the handover means 1017 is completed, the response means 1018 responds to the inquiry means 5016 with information indicating that the handover process has been completed as an inquiry result. When there is no handover data, the response means 1018 responds to the inquiry means 5016 with information indicating that there is no handover data as an inquiry result.

[0278] [Operation description related to the instructor change process] FIG. 51 is a sequence diagram showing an example of the instructor change process in the settlement system according to the modification. FIG. 51 corresponds to FIG. 48 in the embodiment.

[0279] First, with the replacement of the instructor, the new instructor inputs the employee code as his / her instructor identification information to the instruction device 50. Accordingly, the processor 501 acquires the instructor identification information of the new instructor (ACT341).

[0280] In response to the acquisition of the employee code of the new instructor, the processor 501 inquires of the hold server 10 about the presence or absence of handover data by transmitting the employee code of the current instructor and the employee code of the new instructor to the hold server 10. In other words, the processor 501 inquires of the hold server 10 about the presence or absence of hold data stored in association with the operator identification information that matches the instructor identification information of the current instructor.

[0281] When the processor 101 receives an inquiry about hold data from the instruction device 50, it determines the presence or absence of hold data stored in association with the employee code of the current instructor.

[0282] If there is pending data stored in association with the employee code of the current instructor (when there is transfer data in FIG. 51), the processor 101 executes the transfer process for the pending data (ACT343). Specifically, the processor 101 stores the pending data stored in association with the employee code of the current instructor again in association with the employee code of the new instructor. As a result, the pending data stored in the per-employee folder 1033 of the current instructor moves to the per-employee folder 1033 of the new instructor.

[0283] After ACT343, the processor 101 transmits a notification indicating that the transfer process of the pending data to be queried has been completed to the instruction device 50 as the result of the query (ACT344).

[0284] If there is no pending data stored in association with the employee code of the current instructor (when there is no transfer data in FIG. 51), the processor 101 transmits a notification indicating that there is no pending data to be queried to the instruction device 50 as the result of the query (ACT345).

[0285] Upon receiving the notification indicating that the transfer process of the pending data has been completed or the notification indicating that there is no pending data to be queried, the processor 501 changes the instruction authority from the current instructor to the new instructor (ACT346). That is, the processor 501 determines that the employee code of the new instructor is included in the first signal when the call button BEa is input hereafter, and overwrites the employee code stored in the employee memory 5031 from the current instructor to the new instructor. Note that the processor 501 may further display on the instruction screen SEa a text indicating that the instruction authority from the current instructor to the new instructor has been changed.

[0286] Thus, the instructor change process ends.

[0287] Here, the processor 501 realizes the function as the inquiry means 5016 by executing the process of ACT342. The processor 101 realizes the function as the handover means 1017 by executing the process of ACT343. The processor 101 realizes the function as the response means 1018 by executing the process of ACT344 or ACT345.

[0288] [Description of the operation related to the instructor change process] According to the modification, when the first hold data associated with the operator identification information that matches the instructor identification information of the current instructor is held in the hold server 10, the handover means 1017, in response to an inquiry from the inquiry means 5016, transfers the operator identification information associated with the first hold data from the instructor identification information of the current instructor to the instructor identification information of the new instructor. Thereby, the determination means 5017 can change the instructor from the current instructor to the new instructor regardless of the presence or absence of the first hold data. Therefore, it is possible to avoid an operation error such as the occurrence of a customer who cannot execute the settlement process in either the transaction processing device 30 or the settlement device 40, and to more smoothly execute the replacement of employees.

[0289] <Other embodiments> The basic configuration of the settlement system 100 is not limited to that shown in FIG. 1. FIG. 52 illustrates another settlement system 200. In the settlement system 200, an input device 20 and a transaction processing device 30 are arranged in one settlement lane L, and the settlement device 40 and the instruction device 50 are shared in two adjacent settlement lanes L. In the settlement system 200, a space SP for the store clerk is provided between two adjacent settlement lanes L. Then, the settlement device 40 and the instruction device 50 are arranged between the transaction processing device 30 in one settlement lane L and the transaction processing device 30 in the other settlement lane L. With such an arrangement, a customer in one settlement lane L can self-operate the transaction processing device 30 or the shared settlement device 40 in that settlement lane L to settle the transaction. Similarly, a customer in the other settlement lane L can self-operate the transaction processing device 30 or the shared settlement device 40 in that settlement lane L to settle the transaction.

[0290] Note that by sharing the instruction device 50, it is necessary to change the layout of the instruction screen displayed on the touch panel 54. FIG. 53 is an example of the instruction screen SEb of the instruction device 50 in the settlement system 200. The instruction screen SEb divides the screen of the touch panel 505 into two equal parts horizontally. On the left side, there are arranged the lane number of the lane L located on the left side facing the instruction screen SEb, for example, "001", the pull-down area AEaa, the call button BEaa, the numeric keypad icon BEba, and the camera icon BEca. On the right side, there are arranged the lane number of the lane L located on the right side facing the instruction screen SEb, for example, "002", the pull-down area AEab, the call button BEab, the numeric keypad icon BEbb, and the camera icon BEcb.

[0291] By setting the screen of the touch panel 54 of the instruction device 50 shared by two adjacent lanes as the instruction screen SEb, the clerk X who serves customers in the lane with the lane number "001" selects his / her own name in the pull-down area AEaa. Alternatively, the clerk X who serves customers in the lane with the lane number "001" inputs his / her employee code using the numeric keypad icon BEba or the camera icon BEca. The clerk Y who serves customers in the lane with the lane number "002" selects his / her own name in the pull-down area AEab. Alternatively, the clerk Y who serves customers in the lane with the lane number "002" inputs his / her employee code using the numeric keypad icon BEbb or the camera icon BEcb. By such operations, the employee code of the 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 the clerk Y is stored in association with the lane number "002".

[0292] In addition, the call button BEaa becomes valid at the timing when the transaction file processed in the lane with lane number "001" is stored in the hold server 10. Therefore, when the store clerk X touches the call button BEaa, on the condition that the settlement device 40 is available, the transaction file stored in the employee-specific folder 1033 with the employee code of the store clerk X set is output from the hold server 10 to the settlement device 40. Thus, the customer of the transaction processed in the lane with lane number "001" can settle the transaction with the settlement device 40.

[0293] Similarly, the call button BEab becomes valid at the timing when the transaction file processed in the lane with lane number "002" is stored 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 stored 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 lane number "002" can settle the transaction with the settlement device 40.

[0294] 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 it is 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 hold flag Fb is "0", it proceeds to ACT141 of FIG. 14.

[0295] In the above embodiment, it was described that when the call button BEa of the instruction device 50 is input, the settlement device 40 receives the instruction from the instruction device 50 and outputs a first signal 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, the first signal may be directly output from the instruction device 50 to the hold server 10.

[0296] 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 inputtable 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 inputtable.

[0297] In the above embodiment, the case of using a tablet terminal as the instruction device 50 was exemplified. The instruction device 50 is not limited to a tablet terminal. For example, as the settlement device 40, a touch panel for store clerk operation is provided separately from the touch panel 41 for customer operation. 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 touch panel 41 for customer operation. Specifically, the processor 401 sets the screen of the touch panel for store clerk operation as the instruction screen SEa. 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.

[0298] Although some embodiments of the present invention have been described, these embodiments are presented by way of example 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 and gist of the invention, and are also included in the invention described in the claims and the equivalent scope thereof.
