Description

[Technical field]

[0001] The present invention relates to a POS register, a program, and a processing method for an electronic money storage medium. [Background technology]

[0002] There is known a POS register that has a cashier side input unit where a store clerk (cashier) performs operations related to registering products, such as inputting product codes and determining transaction amounts, and a customer side input unit where a customer performs operations related to payment (see, for example, Patent Document 1). This type of POS register is also called a face-to-face type, since the store clerk and the customer are positioned facing each other across the POS register. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2009-104553 A Summary of the Invention [Problem to be solved by the invention]

[0004] Electronic money cards have become widespread. Customers deposit (charge) funds into electronic money cards in advance, and when making a payment (settlement), the amount is deducted from the deposited amount. Payments using such electronic money cards do not require, for example, the customer to take cash out of their wallet and hand it to a store clerk, and the store clerk also does not need to take change out of the change machine and hand it to the customer. This has the advantage of reducing the time required for checkout.

[0005] However, for example, when attempting to make a payment using an electronic money card, a customer may realize that the credit balance on the electronic money card is insufficient to cover the cost, or may not be sure whether the credit balance on the electronic money card is sufficient to cover the cost. In such a case, if the customer wishes to make a payment using an electronic money card, the customer must ask the store clerk to check the credit balance of the electronic money card, and if the credit balance is insufficient, the clerk must deposit money into the electronic money card. After that, the customer can make the payment using the electronic money card, which has a credit balance equal to or greater than the amount of the purchase. When processing related to the management of the deposited balance of an electronic money card, such as checking the deposited balance of an electronic money card or depositing money into the electronic money card, a customer requests a store clerk to carry out processing related to the management of the deposited balance of an electronic money card. Then, the store clerk, who is performing registration processing of the product purchased by the customer, performs operations such as execution or acceptance of processing related to the management of the deposited balance of an electronic money card in response to the request from the customer. In this case, the store clerk temporarily suspends (puts on hold) the work currently being performed, such as the registration processing of the product, and performs operations related to the balance check or deposit desired by the customer. Then, when the processing related to the management of the deposited balance is completed, the store clerk resumes the work such as the registration processing of the product that was temporarily suspended (put on hold). In such a situation, the store clerk has to spend time and effort to perform operations related to the management of the deposited balance of an electronic money card during the transaction, which delays the time until the transaction with the customer is completed.

[0006] The present invention has been made in consideration of the above circumstances, and aims to make it possible to shorten the time required to complete a transaction even when processing related to managing the deposited balance of an electronic money card is required when making a payment at a POS register.

[0014] A POS register (product sales data processing device) according to one embodiment of the present invention will be described below. The POS register of this embodiment is a face-to-face type in which a store clerk who operates the POS register to register products and a customer who operates the POS register to pay for the products face each other. First, an example of the appearance of the POS register of this embodiment will be described with reference to FIGS. FIG. 1 is a perspective view of a POS register 100 of this embodiment installed on a counter 200, as viewed from the side where a store clerk (operator) who operates the POS register 100 stands. FIG. 2 is a perspective view of the POS register 100 of this embodiment installed on a counter 200, as viewed from the side where a customer stands. FIG. 3 is an enlarged view of a portion of the POS register 100 shown in FIG. FIG. 4 is an enlarged view of the POS register 100 shown in FIG.

[0015] In the following description, the side of the POS register 100 where a customer stands may be referred to as the front side of the POS register 100, and the side of the POS register 100 where a store clerk stands may be referred to as the rear side of the POS register 100.

[0016] 1 to 4, the POS register 100 of this embodiment includes a change machine unit 101, an operation unit 103, a POS register main body 105, a printer 107, a scanner 108, and a reader / writer 109. Note that the reader / writer 109 is shown only in Fig. 4 for the sake of convenience in order to avoid cluttering the illustrations in Figs. 1 to 3.

[0017] The change machine unit 101 includes a change machine having a money insertion / discharge section 121a, and a housing 110. The change machine is used by customers to make payments. The change machine is stored in the housing 110 with the money insertion / discharge section 121a exposed on the front side.

[0018] Furthermore, the housing 110 has a structure that allows it to be placed on a mounting plate. For example, a structure that allows the housing 110 to be placed on a mounting plate is one in which the bottom surface of the housing 110 has a shape that allows the housing 110 to be stably positioned on the mounting plate when the housing 110 is placed on the mounting plate. Note that, for example, a configuration in which rubber feet or the like are provided at the four corners of the bottom surface of the housing 110 is also a structure that allows the housing 110 to be placed on a mounting plate. In the cases of the above figures, the placement plate on which the housing 110 is placed is the table 203 of the counter 200.

[0019] The money insertion and ejection unit 121a is a portion used by a customer to, for example, pay the bill and receive change. The money insertion and ejection unit 121a is provided with a bill insertion slot, a coin insertion slot, a bill ejection slot, and a coin ejection slot.

[0020] The operation unit 103 includes a touch panel display unit 131 and a keyboard 132 that are used by a store clerk for operation. As shown in the figure, the clerk touch panel display unit 131 and the keyboard 132 are installed so that the parts where operations are performed face the position where the clerk is standing. In other words, the clerk touch panel display unit 131 and the keyboard 132 are arranged in an orientation that allows them to be operated by a clerk positioned behind the POS register 100. Operation unit 103 also includes customer touch panel display unit 133. Customer touch panel display unit 133 displays product registration details, accounting information, and the like to customers, and is the area where customers perform operations related to payment. As shown in the figure, customer touch panel display unit 133 is positioned so that the screen faces the side (front) where the customer is standing.

[0021] The operation unit 103 is configured by unitizing (integrating) the above-mentioned touch panel display unit for clerk 131, keyboard 132, and touch panel display unit for customer 133. Then, the operation unit 103 thus unitized is attached to the upper surface of the housing 110. At this time, the operation unit 103 is fixed to the housing 110, for example, by screwing at a predetermined portion not shown in the above drawings.

[0022] Also, operation unit 103 is disposed toward the front of the top surface of housing 110. As a result, a surface portion having a certain area or more where nothing is placed, i.e., article placement surface portion 115, is formed on the rear side of the top surface of housing 110 as shown in Fig. 3. Article placement surface portion 115 is used as a place where, for example, a store clerk places articles such as products to be registered and scanner 108.

[0023] The POS register main unit 105 is a central unit of the POS register 100 and executes various processes related to product registration and settlement in response to operations performed on the store clerk touch panel display unit 131 or keyboard 132 .

[0024] The POS register main body 105 controls the operation of the change machine in the change machine unit 101. The POS register main body 105 can also register products using code data based on barcodes read by a scanner 108. The POS register main body 105 can also control a printer 107 to print receipts and the like.

[0025] 1, the POS register main unit 105 is installed between shelves provided on the side of the stand of the store clerk on the platform 201 of the counter 200. In other words, the POS register main unit 105 is installed in a place that is not visible to customers and does not get in the way of the store clerk.

[0026] The POS register main body 105 and the change machine in the change machine unit 101 are communicatively connected via a cable. The POS register main body 105 and the operation unit 103 are also communicatively connected via a cable. 1 and 3 show a state in which the cable CBL is pulled out from the rear side surface of the housing 110. The cable CBL here collectively represents a cable that connects the change machine unit 101 and the POS register main body 105, and a cable that connects the operation unit 103 and the POS register main body 105. The printer 107 may also be connected to the POS register main body 105 by a cable. The scanner 108 may also be connected to the POS register main body 105 by a cable. The cable connecting the printer 107 and the POS register main body 105 and the cable connecting the scanner 108 and the POS register main body 105 may also be combined so as to be included in the cable CBL. 1 and 3, the cable CBL drawn out from the rear side surface of the housing 110 is connected to the POS register main body 105 on the side of the counter 200 where the store clerk stands. In this way, the cable CBL connecting the change dispenser unit 101 and the operation unit 103 side to the POS register main body 105 is also routed in a manner that is not visible to customers. Note that communication between at least one of the change dispenser, the operation unit 103, etc. and the POS register main body 105 may be performed wirelessly instead of via a cable.

[0027] As described above, the printer 107 prints receipts and the like under the control of the POS register main unit 105. Note that the printer 107 may also be configured to print receipts and the like.

[0028] Some stores manage products by printing barcodes containing product information (such as product name and price) on the product packaging or by attaching labels with barcodes printed on them to the products. The scanner 108 obtains the code data by reading the barcode attached to the product in this manner. The obtained code data is input, for example, by the POS register main unit 105. The POS register main unit 105 collates the input code data with data such as a product master to identify the product name, price, etc., and executes the product registration process using the identified product name, price, etc.

[0029] The reader / writer 109 is a device that reads and writes data corresponding to the electronic money card 300 by communicating with an IC (Integrated Circuit) card serving as the electronic money card 300. The electronic money card 300 is used, for example, after money has been deposited in advance, and when paying the price, the amount is deducted from the deposited amount. In this embodiment, the reader / writer 109 communicates with the electronic money card 300 in a contactless manner.

[0030] The reader / writer 109 transmits the data read from the electronic money card 300 to the POS register main unit 105. The POS register main unit 105 executes processing according to the transmitted read data from the electronic money card 300, and outputs data to be written to the electronic money card 300 to the reader / writer 109. The reader / writer 109 writes the data transmitted from the POS register main unit 105 to the electronic money card 300 of the communication partner. As described above, the reader / writer 109 reads and writes data from and to the electronic money card 300, so that the POS register 100 of this embodiment can perform accounting processing corresponding to the payment (settlement) of the price using the electronic money card 300.

[0031] Fig. 5 is a block diagram showing an example of the configuration of a POS register 100. In the figure, the same parts as those in Figs. 1 to 4 are given the same reference numerals and their explanations are omitted. As shown in the figure, the POS register 100 is configured to include a change machine unit 101, an operation unit 103, a POS register main body 105, a printer 107, a scanner 108, and a reader / writer 109, all of which have been explained in Figs. 1 to 4.

[0032] First, a description will be given of the configuration of the POS register main body 105. The POS register main body 105 shown in the figure includes a CPU (Central Processing Unit) 151, a RAM (Random Access Memory) 152, a storage unit 153, an input / output unit 154, and a network interface 155. The CPU 151, the RAM 152, the storage unit 153, the input / output unit 154, and the network interface 155 are connected via a bus 156.

[0033] The CPU 151 executes a program stored in the storage unit 153 to perform control for realizing various functions of the POS register 100 . The RAM 152 is a main storage device corresponding to the CPU 151, and is used as a working area when the CPU 151 executes processing. The storage unit 153 is an auxiliary storage device corresponding to the CPU 151, and stores various types of information used by the CPU 151. The input / output unit 154 is a part that inputs and outputs data or signals between the POS register 100 and units other than the POS register main body 105 (the change machine unit 101, the operation unit 103) and devices (the printer 107, the scanner 108, the reader / writer 109), etc. The network interface 155 communicates with other devices in the store (such as a master device, other POS registers, and mobile terminals of store clerks) via, for example, a local area network (LAN) in the store. For example, by being connected to a master device via a network, the POS register 100 of this embodiment can function as a Point Of Sales (POS) POS register.

[0034] The change machine 120 in the change machine unit 101 is connected to the input / output unit 154 of the POS register main body 105 so as to enable input and output of data and signals therebetween.

[0035] The operation unit 103 also includes a touch panel display unit 131 for store clerks, a keyboard 132, a touch panel display unit 133 for customers, and an input / output unit 134. The input / output unit 134 is a part that inputs and outputs data or signals between each of the clerk touch panel display unit 131, the keyboard 132, and the customer touch panel display unit 133 equipped in the operation unit 103, and the input / output unit 154 of the POS register main body 105.

[0036] In the figure, an example is shown in which a printer 107, a scanner 108, and a reader / writer 109 external to the operation unit 103 are connected to the input / output unit 134. That is, the input / output unit 134 shown in the figure is adapted to input and output data and signals between the printer 107 and the input / output unit 154 of the POS register main body 105 . The input / output unit 134 also inputs and outputs data and signals between the scanner 108 and the input / output unit 154 of the POS register main body 105 . The input / output unit 134 is adapted to input and output data or signals between the reader / writer 109 and the input / output unit 154 of the POS register main body 105 . At least one of the printer 107, the scanner 108, and the reader / writer 109 may be configured to be connected to the input / output unit 154 of the POS register main body 105 without passing through the input / output unit 134 of the operation unit 103.

[0037] In addition, the communication line for connecting the change machine 120 in the same figure to the input / output unit 154 of the POS register main body 105, and the communication line for connecting the input / output unit 134 of the operation unit 103 are physically included in the cable CBL shown in Figure 1.

[0038] As described above, the input / output unit 154 of the POS register main body 105 is connected to the change machine 120 , so that the CPU 151 of the POS register main body 105 can control the change machine 120 . Furthermore, by connecting the input / output unit 154 of the POS register main body 105 to the input / output unit 134 in the operation unit 103, the CPU 151 of the POS register main body 105 can input an operation signal corresponding to an operation performed on the clerk touch panel display unit 131 or the keyboard 132, and execute a predetermined process in response to the operation. The CPU 151 can also execute display control for the clerk touch panel display unit 131 and the customer touch panel display unit 133. Furthermore, by connecting the input / output unit 154 of the POS register main body 105 to the input / output unit 134 in the operation unit 103, the CPU 151 can control the printer 107. The CPU 151 can also input code data corresponding to a barcode read by the scanner 108. The CPU 151 can also input data read from the electronic money card 300 by the reader / writer 109, and can control the reader / writer 109 to write the data to the electronic money card 300.

[0039] A basic example of how the POS register 100 having the configuration described with reference to Figures 1 to 5 is used in a store will be described. Note that the description here will be given taking as an example a case where the store in which the POS register 100 is installed is a bakery shop. At a bakery shop, a customer selects the bread they wish to purchase from the breads displayed and places it on a tray. To purchase the selected bread, the customer moves with the tray on which the bread is placed to the front of the counter where the POS register 100 is installed. At this time, the customer stands in front of the POS register 100, where the coin insertion / discharge unit 121a faces. The customer then hands the tray on which the bread to be purchased is placed to a store clerk standing behind the POS register 100.

[0040] While checking the products on the tray, the store clerk operates the store clerk touch panel display unit 131, keyboard 132, scanner 108, etc. in the operation unit 103 to cause the POS register 100 to register the products and calculate the total price of the registered products. In response to such operations, the CPU 151 in the POS register main body 105 executes the product registration process. The CPU 151 also executes control to cause the store clerk touch panel display unit 131 to display the details of the registered products, the total price of the registered products, etc., as needed. The CPU 151 also causes the customer touch panel display unit 133 to display predetermined information to be presented to the customer, including the details of the registered products, the total price of the registered products, etc.

[0041] After checking the total amount, the customer can make the payment (settlement) in cash as follows: The customer inserts currency (banknotes, coins) in an amount equal to or greater than the total amount through a banknote insertion slot or a coin insertion slot in currency insertion / discharge section 121a. As currency is inserted as described above, change machine 120 in change machine unit 101 detects the type of inserted currency and the number of each type, and transmits inserted currency information indicating the detection results to POS register main body 105. CPU 151 in POS register main body 105 calculates the total amount of inserted currency (deposit) based on the received inserted currency information. The change dispenser 120 may calculate the deposit amount and transmit the calculated deposit amount to the POS register main body 105 .

[0042] If the calculated deposit is equal to the total amount, no change is required. In this case, the CPU 151 in the POS register main body 105 executes control so that the printer 107 prints a receipt without discharging the change from the change dispenser 120. On the other hand, if the calculated deposit is more than the total amount, the CPU 151 in the POS register main body 105 subtracts the total amount from the deposit to calculate the amount of change. Then, the CPU 151 controls the change dispenser 120 so that the calculated amount of money is discharged as change from the bill discharge port and coin discharge port of the money insertion and discharge unit 121a. The customer receives the discharged money as change. In the following description, the process executed by CPU 151 in response to a cash payment as described above is also referred to as a cash-operated payment process.

[0043] In addition, the customer can also pay (settle) the price using an electronic money card 300 (an example of an electronic money storage medium). The electronic money storage medium is a storage medium that has a function for depositing and withdrawing electronic money (depositing and paying). For example, RFID (Radio Frequency IDentification) is used as the electronic money storage medium. In this embodiment, the payment can also be made by a smartphone, mobile phone, or other device that functions as an electronic money storage medium. However, in the following description, for ease of understanding, the case where the payment is made by the electronic money card 300, which is a card-type electronic money storage medium, will be described as an example.

[0044] When paying using electronic money card 300, the customer performs an operation on touch panel display unit 131 for store clerk to select the use of electronic money card 300 as the payment method (electronic money card use selection operation), for example. In response to the electronic money card use selection operation, the CPU 151 executes a payment process corresponding to the use of the electronic money card 300 (hereinafter, also referred to as electronic money compatible payment process). That is, CPU 151 displays, on customer touch panel display unit 133, a payment-related screen corresponding to the payment of the price using electronic money card 300. The customer checks the payment amount and the like displayed on the displayed payment-related screen, and holds electronic money card 300 over reader / writer 109 to cause communication between reader / writer 109 and electronic money card 300. The reader / writer 109 reads data necessary for settlement, such as data on the credit balance, from the electronic money card 300, and outputs the read data to the CPU 151. The CPU 151 performs settlement processing using the input data, for example, by subtracting (subtracting) the subtotal from the credit balance indicated by the input data. The CPU 151 outputs write data including the value of the credit balance after subtracting the subtotal to the reader / writer 109. The reader / writer 109 writes the input write data to the electronic money card 300. As a result, the credit balance in the electronic money card 300 is reduced according to the price of the product purchased by the customer. In this manner, payment is made using the electronic money card 300.

[0045] In this way, by using the POS register 100 of this embodiment, the transaction for the bread purchased by the customer can be carried out face-to-face between the customer and the store clerk. Furthermore, in the case of the POS register 100 of this embodiment, the payment of the price and the receipt of the change are carried out between the customer and the money inserting and ejecting unit 121a, and money is not handed over between the customer and the store clerk. In other words, the store clerk does not need to handle cash or the electronic money card 300 in his / her hand. This eliminates the need for the store clerk to hold bread in the hand that holds the cash or the electronic money card 300, improving hygiene.

[0046] Furthermore, the POS register 100 in this embodiment can accept operations to deposit (charge) money into the customer's electronic money card 300 and execute the deposit process until the customer's transaction corresponding to the product registration is completed, specifically, during the period from when the operation to register the first product is accepted to when the subtotal operation to indicate the subtotal of the registered products is accepted (the product registration period). That is, with the POS register of this embodiment, a customer who has registered a product can deposit money into the electronic money card 300 in parallel with the store clerk performing the operation to register the product. When a customer wishes to deposit money into the electronic money card 300 when the store clerk does not simultaneously register the product and deposit money into the electronic money card 300, the customer first completes the product registration and the subtotal, and then asks the store clerk to deposit money into the electronic money card 300. The customer then makes a payment using the electronic money card 300 into which the money has been deposited. In this case, the payment takes a long time because the electronic money card 300 is deposited between the product registration and the payment using the electronic money card 300. In contrast, in this embodiment, the electronic money card 300 is charged while the product is being registered, so that once the product is registered, payment can be made immediately using the electronic money card 300. In other words, according to this embodiment, even if the electronic money card 300 is charged at the time of payment, the payment can be completed in a short time.

[0047] Hereinafter, a configuration for enabling depositing money into the electronic money card 300 when a product is being registered in the POS register 100 of this embodiment will be described. First, FIG. 6 shows one of the payment-related screens displayed on customer touch panel display unit 133, and shows an example of a product registration status screen that is displayed when a store clerk is registering a product. The product registration status screen in the figure shows the product registration status. The product registration status screen has a registered product display area AR1 and a total amount display area AR2. The registered product display area AR1 and the total amount display area AR2 show the product registration status.

[0048] In the registered product display area AR1, the quantity and price of each product that the store clerk has registered are displayed. For example, the contents of the registered product display area AR1 change each time a new product is registered to show the contents corresponding to the registered product. The total amount display area AR2 displays the number of products registered up to now, the total amount corresponding to the registered products, etc. The contents of the total amount display area AR2 change so that each time a new product is registered, the number and the total amount increase according to the registered product. The customer can check whether there are any errors between the product he or she purchased and the product registration result by looking at the contents displayed in the registered product display area AR1 and the total amount display area AR2.

[0049] Furthermore, on the product registration status screen, a deposit instruction button BT1 and a deposit balance confirmation button BT2 are further arranged. The deposit instruction button BT1 is a button that the customer operates to instruct a deposit into the electronic money card 300. The deposit balance confirmation button BT2 is a button that the customer operates to instruct a confirmation of the deposit balance of the electronic money card 300. Here, the product registration status screen is a payment-related screen that is displayed from the start of product registration until the subtotal amount is finalized, that is, while the product is being registered. The deposit instruction button BT1 and the deposit balance confirmation button BT2 are arranged on the product registration status screen. In this embodiment, this allows the customer to deposit money into the electronic money card 300 or to confirm the deposit balance of the electronic money card 300 while the product is being registered.

[0050] Here, an example is taken of a case where a customer notices that the amount deposited on the electronic money card 300 has decreased while the product is being registered, and wants to deposit money into the electronic money card 300. In this case, while the product is being registered, the customer performs a touch operation by touching the deposit instruction button BT1 arranged on the product registration status screen displayed on the customer touch panel display unit 133 with his / her finger. Then, the customer holds the electronic money card 300 he / she possesses over the reader / writer 109, and communication is performed between the reader / writer 109 and the electronic money card 300. When the deposit instruction button BT1 is touched as described above and communication between the reader / writer 109 and the electronic money card 300 becomes possible, the customer touch panel display unit 133 shifts from displaying the product registration status screen to displaying the deposit operation screen.

[0051] FIG. 7 shows an example of a deposit operation screen displayed on the customer touch panel display unit 133. The deposit operation screen in the figure has a deposit balance display area AR11. The deposit balance display area AR11 shows the deposit balance of the electronic money card 300. In the deposit balance display area AR11, where no deposit has been made yet, the deposit balance of the electronic money card 300 before the deposit is made is shown. The figure shows an example in which "120 yen" is displayed as the deposit balance of the electronic money card 300 before the deposit.

[0052] Furthermore, on the deposit operation screen, deposit amount selection buttons BT11, BT12, BT13, and BT 14 are arranged. The deposit amount selection buttons BT11, BT12, BT13, and BT 14 are buttons for selecting the amount to be deposited into the electronic money card 300, respectively. A customer who wishes to deposit money into the electronic money card 300 touches a deposit amount selection button that indicates the amount he or she wishes to deposit among the deposit amount selection buttons BT11, BT12, BT13, and BT14. The CPU 151 sets the amount corresponding to the deposit amount selection button that has been touched as the deposit amount.

[0053] After touching the deposit amount selection button, the customer deposits cash equivalent to the deposit amount selected by touching the deposit amount selection button into the banknote deposit slot or coin deposit slot of the money deposit / discharge section 121a in order to deposit money into the electronic money card 300. For example, if a customer wishes to deposit 5,000 yen, the customer touches the deposit amount selection button BT12 and deposits 5,000 yen in cash into the bill deposit slot or coin deposit slot of the money deposit / ejection unit 121a.

[0054] The deposit operation screen includes a deposit amount display area AR12, which displays the amount of cash deposited by the customer. The amount displayed in the deposit amount display area AR12 shows 0 yen when the deposit operation screen is initially displayed. Then, when a customer inserts cash into the banknote insertion slot or coin insertion slot of the currency insertion / dispensing unit 121a after touching the deposit amount selection button, the amount displayed in the deposit amount display area AR12 increases according to the amount inserted. In this case, when the amount of cash inserted reaches the deposit amount selected in response to the operation of the deposit amount selection button, the deposit amount display area AR12 shows the selected deposit amount, and, for example, the currency insertion / dispensing unit 121a enters a state in which it cannot accept any more cash deposits.

[0055] Alternatively, in the deposit amount display area AR12, the deposit amount selected in response to the operation of the deposit amount selection button may be presented, and then the remaining deposit amount (the amount obtained by subtracting the amount inserted from the selected deposit amount) may be displayed as the customer inserts cash into the currency insert / discharge unit 121a. In this case, when the amount of cash inserted reaches the deposit amount selected in response to the operation of the deposit amount selection button, the deposit amount display area AR12 shows 0 yen, and, for example, the currency insert / discharge unit 121a enters a state in which it will not accept any more cash deposits. The deposit balance displayed in the deposit balance display area AR11 may also be set to increase in accordance with the amount of cash deposited.

[0056] The displays in the deposit amount display area AR12 and the deposit balance display area AR11 in response to the operation of the deposit amount selection button and the insertion of cash into the money insertion / ejection unit 121a are performed under the control of the CPU 151. That is, CPU 151 recognizes the deposit amount by inputting an operation signal corresponding to an operation on the deposit amount selection button from customer touch panel display unit 133. Also, information indicating the denomination and number of cash inserted into coin insertion / ejection unit 121a is transmitted from change machine 120 to CPU 151. CPU 151 calculates the deposited cash based on the denomination and number of cash received from change machine 120. CPU 151 can display the amount in each of the deposited amount display area AR12 and the deposited balance display area AR11 using the recognized deposit amount and the calculation result of the deposited cash.

[0057] Then, when the cash deposit corresponding to the deposit amount selected by operating the deposit amount selection button has been completed, the deposit balance display area AR11 displays the deposit amount obtained by adding the current deposit amount to the deposit balance of the electronic money card 300 before this deposit. As a specific example, if the amount of the current deposit is 5,000 yen, 5,120 yen will be displayed in the deposit balance display area AR11 at the stage when the cash deposit is completed. When the customer confirms that the deposit balance displayed in the deposit balance display area AR11 is correct, he or she operates the "Back" button BT16 on the deposit operation screen. In response to the operation of the "Back" button BT16, the customer touch panel display unit 133 switches to display the product registration status screen of Fig. 6. When the product registration status screen is displayed in this way, the registered product display area AR1 reflects the product that was last registered at that time, and the total amount display area AR2 displays the number of products registered up to that time and the total amount. The "Back" button BT16 can also be operated when, for example, a deposit operation screen is displayed, but the customer wants to stop depositing money into the electronic money card 300 and return to the product registration status screen without operating the deposit amount selection button.

[0058] Also, for example, if a customer wishes to interrupt a deposit into the electronic money card 300 while depositing cash after operating the deposit amount selection button on the deposit operation screen, the customer can simply operate the “Cancel” button BT15. In response to the operation of the "Cancel" button BT15, the CPU 151 interrupts the deposit process that has been in progress. Specifically, the CPU 151 causes the cash that has been deposited so far to be discharged from the currency insertion and dispensing unit 121a, and switches the display on the customer touch panel display unit 133 to a product registration status screen.

[0059] In addition, when a customer wishes to check the deposit balance of the electronic money card 300 while the product registration has been performed and the product registration status screen (FIG. 6) is displayed on the customer touch panel display unit 133, the customer performs a touch operation on the deposit balance check button BT2. In addition, the customer holds the electronic money card 300 over the reader / writer 109, thereby making the reader / writer 109 and the electronic money card 300 communicable with each other.

[0060] When the deposit balance confirmation button BT2 is touched as described above and the reader / writer 109 and the electronic money card 300 are enabled to communicate with each other, the display on the customer touch panel display unit 133 switches from the product registration status screen to the deposit balance confirmation screen. Fig. 8 shows an example of a deposit balance confirmation screen. In the deposit balance confirmation screen in the figure, a deposit balance display area AR21 is arranged. In the deposit balance display area AR21, the deposit balance of the electronic money card 300 is displayed. The electronic money card 300 whose deposit balance is displayed in the deposit balance display area AR21 is the electronic money card 300 whose data has been read by the reader / writer 109 as a result of being held up to the reader / writer 109.

[0061] Furthermore, a deposit instruction button BT21 is arranged on the deposit balance confirmation screen. The deposit instruction button BT21 is a button for performing an operation to instruct a deposit to the electronic money card 300. For example, when the deposit balance displayed in the deposit balance display area AR21 on the deposit balance confirmation screen is less than expected and the customer wishes to deposit money into the electronic money card 300, the customer can simply touch the deposit instruction button BT21. That is, when the customer checks the deposit balance on the deposit balance confirmation screen and determines that it is necessary to deposit money into the electronic money card 300, the customer can issue a deposit instruction operation from the same deposit balance confirmation screen. In other words, the customer does not need to take the troublesome procedure of returning the display on the customer touch panel display unit 133 from the deposit balance confirmation screen to the product registration status screen and then operating the deposit instruction button BT1.

[0062] When the deposit instruction button BT21 on the deposit balance confirmation screen is touched, the display on the customer touch panel display unit 133 switches from the deposit balance confirmation screen of FIG. 8 to the deposit operation screen of FIG. The customer can then deposit the required amount by performing the same operations as described above on the displayed deposit operation screen. Once the deposit into the electronic money card 300 is complete, the display on the customer touch panel display unit 133 also returns to the product registration status screen in Fig. 6. Even when the display switches to the product registration status screen in this way, the registered product display area AR1 still reflects the product that was last registered at that time, and the total amount display area AR2 displays the number of products registered up to that time and the total amount. Furthermore, when the customer wishes to return from the deposit balance confirmation screen to the product registration status screen without depositing money into the electronic money card, the customer can simply operate the "Back" button BT22.

[0063] Then, when the registration of the products is completed, the store clerk performs an operation to output the subtotal (subtotal operation: for example, an operation on a subtotal button on the store clerk touch panel display unit 131 or keyboard 132). In response to the subtotal operation, a payment guide screen, which is one of the payment-related screens, is displayed on the customer touch panel display unit 133. Fig. 9 shows an example of a payment guide screen. In the payment guide screen in Fig. 9, a payment amount display area AR31 is arranged. In the payment amount display area AR31 in Fig. 9, the number of products registered corresponding to the customer and the total price of the registered products are displayed. The total price displayed in the payment amount display area AR31 is the price to be paid by the customer.

[0064] The customer can pay (settle) the price by either cash or electronic money card 300. First, when making a payment by cash, the customer inserts cash as payment into the money insert / discharge unit 121a while the payment guide screen is displayed. When cash is inserted into the money insertion / ejection unit 121a in this manner, the CPU 151 determines that payment by cash has been selected as the payment method, and performs a payment process corresponding to the inserted cash (cash-compatible payment process).

[0065] On the other hand, when making a payment using the electronic money card 300, the customer touches the electronic money payment selection button BT31 on the payment guide screen. When the electronic money payment selection button BT31 is operated, the CPU 151 determines that the use of the electronic money card 300 has been selected as the payment method, and performs a payment process corresponding to the electronic money card 300 (electronic money compatible payment process).

[0066] When the electronic money payment selection button BT31 is operated to perform electronic money payment processing, the customer touch panel display unit 133 switches from displaying the payment guidance screen of FIG. 9 to displaying the electronic money card usage guidance screen of FIG. The electronic money card usage guidance screen includes a payment amount display area AR41. In the payment amount display area AR41, the number of products registered for the customer and the total price of the registered products are displayed, similar to the payment amount display area AR31 in the settlement guidance screen. Also, on the electronic money card usage guidance screen, guidance is displayed that urges the customer to hold the electronic money card 300 over the reader / writer 109 so that the electronic money card 300 and the reader / writer 109 are ready to communicate with each other.

[0067] Then, the customer holds the electronic money card 300 over the reader / writer 109. When the electronic money card 300 is held over the reader / writer 109 and communication between the electronic money card 300 and the reader / writer 109 becomes possible, the CPU 151 executes an electronic money settlement process. That is, the reader / writer 109 reads data necessary for settlement, such as data on the credit balance, from the electronic money card 300, and outputs the read data to the CPU 151. Then, the CPU 151 performs control so that, for example, the subtotal amount is subtracted from the credit balance indicated by the input data, and the amount after the deduction is written by the reader / writer 109 as the credit balance.

[0068] When payment using an electronic money card cannot be made normally due to a malfunction of reader / writer 109, the customer can call a store clerk by touching store clerk call button BT41 arranged on the electronic money card usage guide screen. When store clerk call button BT41 is operated, for example, a notification is given on store clerk touch panel display unit 131, and the store clerk is notified that a store clerk has been called by the customer.

[0069] When the electronic money payment process is completed, the display on customer touch panel display unit 133 switches from the electronic money card usage guide screen of FIG. 10 to the electronic money payment completion screen of FIG. The electronic money payment completion screen includes a payment amount display area AR51, a pre-payment balance display area AR52, and a post-payment balance display area AR53. In the payment amount display area AR51, the number of products to be settled and the total amount (the amount to be paid by the customer) are displayed. The pre-payment balance display area AR52 displays the credit balance of the electronic money card 300 before a payment corresponding to the use of the electronic money card is made. The post-payment balance display area AR53 displays the credit balance of the electronic money card 300 after a payment corresponding to the use of the electronic money card has been made. The customer can check whether there are any errors in the payment processing results by looking at the contents displayed in the payment amount display area AR51, the pre-payment balance display area AR52, and the post-payment balance display area AR53. The electronic money payment completion screen also displays a message encouraging the customer to receive a receipt showing the results of the payment process.

[0070] Next, an example of a process performed by the POS register 100 of this embodiment will be described with reference to a flowchart of FIG. Step S101: The CPU 151 in the POS register 100 waits for the first (first) product registration operation corresponding to one transaction to be performed. The product registration operation is an operation by a store clerk on the store clerk touch panel display unit 131 and keyboard 132, or an operation of having the scanner 108 read a barcode attached to a product. Step S102: In response to the first product registration operation corresponding to step S101, the CPU 151 performs a product registration process for the product that is the target of the first product registration operation. The product registration process is a process for acquiring, for example, the number of products to be registered, the product name, and the price (unit price). Step S103: In response to the first product registration operation corresponding to step S101, CPU 151 also displays a product registration status screen on customer touch panel display unit 133. CPU 151 also performs display control to display a screen showing the product registration status on clerk touch panel display unit 131 in response to the product registration operation. However, in the figure, for the convenience of making the explanation of the processing of POS register 100 easier to understand, illustration of the display control processing corresponding to clerk touch panel display unit 131 is omitted.

[0071] Step S104: After executing the processes of steps S102 and S103 corresponding to the first product registration operation as described above, the CPU 151 determines whether or not a second or subsequent product registration operation has been performed. Step S105: If it is determined in step S104 that the second or subsequent product registration operation has been performed, the CPU 151 executes a product registration process in response to the product registration operation performed in response to step S104. At this time, if a product registration status screen is displayed on customer touch panel display unit 133, CPU 151 causes the results of the product registration process performed up to that point to be reflected in registered product display area AR1 and total amount display area AR2.

[0072] Step S106: After the product registration process in step S105 is completed, or if it is determined in step S104 that the product registration operation has not been performed, the CPU 151 determines whether or not a deposit confirmation instruction operation has been performed. The deposit confirmation instruction operation here refers to a touch operation on the deposit balance confirmation button BT2 arranged on the product registration status screen in the state in which the product registration status screen in Fig. 6 is displayed.

[0073] Step S107: When a deposit confirmation instruction operation is performed, CPU 151 executes a process to display the deposit balance confirmation screen of Fig. 8 on customer touch panel display unit 133. At this time, CPU 151 acquires the deposit balance contained in the data read from electronic money card 300 by reader / writer 109. CPU 151 causes customer touch panel display unit 133 to display a deposit balance confirmation screen in which the acquired deposit balance amount is shown in deposit balance display area AR21.

[0074] Step S108: After displaying the deposit balance confirmation screen in step S107, the CPU 151 judges whether or not an operation to end the display of the deposit balance confirmation screen has been performed. The operation to end the display of the deposit balance confirmation screen is an operation on the "Back" button BT22 on the deposit balance confirmation screen.

[0075] Step S109: If no operation has been performed to end the display of the deposit balance confirmation screen, CPU 151 judges whether or not a further deposit instruction operation has been performed. The deposit instruction operation judged in step S109 is an operation on the deposit instruction button BT21 on the deposit balance confirmation screen. If no deposit instruction operation has been performed, CPU 151 returns the process to step S108.

[0076] Step S110: If the deposit balance check instruction operation was not performed in the previous step S106, the CPU 151 judges whether or not a deposit instruction operation was performed while the product registration status screen was displayed. The deposit instruction operation judged in step S110 is an operation on the deposit instruction button BT1 on the product registration status screen.

[0077] Step S111: When it is determined in either step S109 or step S110 that a deposit instruction operation has been performed, the CPU 151 performs a deposit process. In the deposit process, the CPU 151 displays the deposit operation screen of Fig. 7 on the customer touch panel display unit 133. Then, as described in Fig. 7, when cash corresponding to the deposit amount selected by a touch operation on the deposit amount selection button is inserted into the currency insertion / ejection unit 121a, the CPU 151 increases the deposit balance of the electronic money card 300 according to the deposit amount.

[0078] Step S112: When the deposit process in step S111 is completed, or when an operation is performed in step S108 to end the display of the deposit balance confirmation screen, the CPU 151 controls the customer touch panel display unit 133 to switch from displaying the deposit operation screen or deposit balance confirmation screen to displaying the product registration status screen.

[0079] Step S113: After executing the process of step S112, or if it is determined in step S110 that a deposit instruction operation has not been performed, CPU 151 determines whether or not a subtotal operation has been performed. As described above, a subtotal operation is an operation performed by a store clerk on store clerk touch panel display unit 131 or keyboard 132 to instruct output of a subtotal of products registered up to that point. If it is determined that a subtotal operation has not been performed, the CPU 151 returns the process to step S104.

[0080] Step S114: On the other hand, if it is determined in step S113 that a subtotal operation has been performed, the CPU 151 causes the customer touch panel display unit 133 to display a payment guide screen (FIG. 9). Step S115: While the payment guide screen is displayed, the CPU 151 determines whether or not electronic money or cash has been selected as the payment method (method of paying the price).

[0081] Step S116: When the customer inserts cash as payment into the currency insert / eject unit 121a while the payment guidance screen is displayed, the change machine 120 sends a notification to the CPU 151 that cash has been inserted (cash insertion notification). When the CPU 151 receives the cash insertion notification, it determines that cash has been selected as the payment method. In this case, the CPU 151 executes a cash-enabled payment process. That is, if the amount of the inserted cash is the same as the price, the CPU 151 accepts the inserted cash as the payment amount and causes the printer 107 to print a receipt indicating the result of the payment process. In addition, if the amount of cash inserted is greater than the price, control is performed to eject the change from the coin insertion / ejection unit 121a, and then a receipt showing the results of the payment process, including the processing corresponding to the change, is printed by the printer 107.

[0082] Step S117: On the other hand, when the electronic money payment selection button BT31 arranged on the payment guidance screen is operated, the CPU 151 judges that the payment method using electronic money has been selected. In this case, the CPU 151 performs the electronic money payment process. In the electronic money payment process, the CPU 151 displays an electronic money card usage guide screen on the customer touch panel display unit 133, and displays an electronic money payment completion screen when the payment is completed.

[0083] By carrying out the process as described above, from the time when the registration of products for one transaction begins until the subtotal operation is performed (while the products are being registered), the customer can deposit funds into the electronic money card 300 and check the deposited balance on the electronic money card 300 by performing the customer's own operations.

[0084] Next, a modified example of this embodiment will be described. In the processing procedure shown in Fig. 12, when a customer uses the electronic money card 300 to make a payment, the customer is required to select payment with the electronic money card 300 on the payment guide screen (by operating the electronic money payment selection button BT31), regardless of whether the electronic money card 300 is charged while the product is being registered. However, if the electronic money card 300 is charged while the product is being registered, it may be considered that the customer intends to continue to make a payment with the electronic money card 300. Considering this, it can be said that it is unnecessary trouble for the customer to perform an operation to select payment with the electronic money card 300 on the payment guide screen, even if the electronic money card 300 is charged while the product is being registered. Therefore, as a modified example, if a deposit is made into the electronic money card 300 between the start of product registration and the time the subtotal operation is performed, electronic money payment processing is performed. In other words, from the customer's point of view, if a deposit is made into the electronic money card 300 during product registration, the POS register 100 transitions directly to electronic money payment processing when the subtotal operation is performed. At this time, when the subtotal operation is performed, for example, the electronic money card usage guide screen (FIG. 10) is immediately displayed on the customer touch panel display unit 133 instead of the payment guide screen (FIG. 9). In this case, the customer does not need to perform an operation to select payment with the electronic money card 300 on the payment guide screen (operation of the electronic money payment selection button BT31). The condition for transitioning to electronic money payment processing is not limited to a customer depositing and charging the electronic money card 300. For example, when the electronic money card 300 is in a state where communication is possible via the reader / writer 109 (when the electronic money card 300 is placed on the reader / writer 109 while checking the deposit balance or simply registering a product, and is in a state where communication is possible via the reader / writer 109), it may be assumed that the customer has performed an operation to select payment with the electronic money card 300 on the payment guidance screen (operation of the electronic money payment selection button BT31) in order to make a payment using the electronic money card 300, and the execution of the cash payment processing may be prohibited and the electronic money payment processing may be performed.

[0085] To realize the above operation, for example, the following process may be added in response to the case where it is determined in step S113 of FIG. 12 that a subtotal operation has been performed. That is, the CPU 151 determines whether or not a deposit has been made into the electronic money card 300 during the period from when the first product registration operation is performed in response to step S101 until when the subtotal operation is performed in response to step S113 (the product registration period). If the electronic money card 300 has not been charged, the CPU 151 advances the process to step S114. On the other hand, if the electronic money card 300 has not been charged, the CPU 151 skips the processes of steps S114 and S115 and proceeds to the process of step S117. By CPU 151 processing in this manner, if a deposit is made to electronic money card 300 while a product is being registered, the customer can proceed to payment with electronic money card 300 without having to perform the operation of selecting use of electronic money card 300 as the payment method on the payment guidance screen.

[0086] As described above, the POS register 100 in this embodiment comprises a clerk operation receiving means for receiving operations performed by a clerk, including operations related to the registration of products; a customer operation receiving means for receiving operations to be performed by a customer, including operations related to the payment for registered products; and an electronic money storage medium compatible processing means for, when the customer operation receiving means receives an operation instructing processing related to the management of the deposited balance of the electronic money storage medium until the customer transaction corresponding to the registration of the product accepted by the clerk operation receiving means is completed, executing processing on the electronic money storage medium in accordance with the instruction received by the customer operation receiving means through communication with the electronic money storage medium via a reader / writer.

[0087] According to the above configuration, until the customer's transaction corresponding to the product registration is completed, the customer can operate the POS register 100 to execute the process related to the management of the deposited balance of the electronic money storage medium. Therefore, the customer can obtain the desired result regarding the management of the deposited balance of the electronic money storage medium without affecting the operation (registration work) such as product registration performed by the store clerk.

[0088] In addition, in the POS register 100 of this embodiment, when the customer operation accepting means accepts an operation by a customer to instruct the deposit of money into the electronic money storage medium until the customer transaction corresponding to the product registration accepted by the store clerk operation accepting means is completed, the electronic money storage medium corresponding processing means executes processing corresponding to the deposit of money into the electronic money storage medium via communication with the reader / writer.

[0089] According to the above configuration, until the customer's transaction corresponding to the product registration is completed, the customer can operate the POS register 100 to execute a process corresponding to the deposit into the electronic money storage medium as a process related to the deposit balance management of the electronic money storage medium. Therefore, the customer can obtain the desired result regarding the deposit balance management of the electronic money storage medium without affecting the operation (registration work) such as product registration performed by the store clerk.

[0090] In addition, in the POS register 100 of this embodiment, when the customer operation accepting means accepts an operation by a customer instructing the customer to check the remaining amount of the deposited amount in the electronic money storage medium until the customer transaction corresponding to the product registration accepted by the store clerk operation accepting means is completed, the electronic money storage medium processing means executes a process of notifying the customer of the remaining amount of the deposited amount in the electronic money storage medium via communication with the reader / writer.

[0091] According to the above configuration, until the customer's transaction corresponding to the product registration is completed, the customer can operate the POS register 100 to execute a process related to the management of the credit balance of the electronic money storage medium, which is to notify the customer of the credit balance of the electronic money storage medium. In other words, while the product is being registered, the customer can operate the POS register 100 himself to check the credit balance of the electronic money card in parallel with the product registration. Therefore, the customer can obtain the desired result regarding the management of the credit balance of the electronic money storage medium, without affecting the operation (registration work) of the store clerk, such as product registration.

[0092] In addition, in the POS register 100 of this embodiment, the customer operation accepting means displays information about the products registered by the store clerk operation accepting means and may further include a product registration status display means that accepts operations to instruct processing related to the management of the deposited balance of the electronic money storage medium.

[0093] According to the above configuration, at the POS register 100, a customer can view the product registration status screen that displays the registration status of the purchased product, and can perform operations on the same product registration status screen to instruct processing related to the management of the deposited balance of the electronic money storage medium. This eliminates the need for a customer to perform operations such as switching from the product registration status screen to another operation screen when, for example, they are trying to perform operations related to the management of the credit balance of the electronic money storage medium while a product is being registered. Therefore, the customer can obtain the desired results regarding the management of the credit balance of the electronic money storage medium without affecting the operations such as product registration performed by the store clerk.

[0094] In addition, in the POS register 100 of this embodiment, the customer operation accepting means may perform payment processing corresponding to the electronic money storage medium without accepting an operation specifying payment by electronic money if at least a deposit is made into the electronic money storage medium before the customer's transaction corresponding to the registration of the product accepted by the store clerk operation accepting means is completed.

[0095] According to the above configuration, if a customer deposits money into the electronic money card before completing a transaction corresponding to the product registration, the customer can proceed to payment using the electronic money card without performing an operation to specify payment by electronic money. This omits the operation to specify payment by electronic money, and shortens the time required for payment.

[0096] In addition, the POS register 100 in this embodiment is further provided with a payment means which, when cash is deposited as the price of registered goods, performs a cash-compatible payment process corresponding to the deposited cash, and, when an operation specifying payment by electronic money is accepted by the customer operation acceptance means, performs an electronic money-compatible payment process by deducting the price from the deposit balance in the electronic money storage medium which communicates with the reader / writer.

[0097] According to the above configuration, the POS register 100 in this embodiment can perform payment processing corresponding to both cash payment and payment using an electronic money card. Furthermore, when performing cash-compatible payment processing, even if the customer does not perform any operation to specify the cash-compatible payment processing, the cash-compatible payment processing is performed as if the customer had specified the cash-compatible payment processing when the customer deposits cash into the POS register 100, and therefore the time required for payment can be shortened.

[0098] A modification of this embodiment will now be described. In the above embodiment, when a customer who has registered a product wishes to check the remaining balance of the electronic money card, the customer operates the Check Balance button BT2 on the product registration status screen (FIG. 6). However, for example, when the POS register 100 performs product registration processing and displays a product registration status screen, the electronic money card 300 may be held over the reader / writer 109, and the reader / writer 109 and the electronic money card 300 may become capable of communicating with each other, and the remaining credit balance of the electronic money card may be displayed. With such a configuration, the customer does not need to operate the customer touch panel display unit 133 in particular to check the remaining credit balance. When displaying the credit balance of the electronic money card in response to the reader / writer 109 and the electronic money card 300 becoming communicable, the display may be changed from the product registration status screen to a credit balance confirmation screen. Alternatively, the display may be left as the product registration status screen without changing to the credit balance confirmation screen, and the credit balance may be displayed at a predetermined position on the product registration status screen.

[0099] For example, railway electronic money cards have a function known as auto-charge (execution amount deposit function) that deposits a fixed amount when the deposit balance falls below a preset amount (execution amount) when passing through a ticket gate. Therefore, the POS register 100 of this embodiment may be configured to prompt the customer to deposit money when the confirmed deposit balance is less than the execution amount when the deposit balance notification process is performed for an electronic money card with the above-mentioned auto-charge function set. In this case, for example, a deposit screen corresponding to the auto-charge function similar to the content of Fig. 7 may be displayed on the customer touch panel display unit 133. Furthermore, the POS register 100 of this embodiment may automatically deposit a preset fixed amount into the electronic money card even if the deposit instruction button BT1 on the product registration status screen is not operated, without displaying a deposit screen corresponding to the auto-charge function on the customer touch panel display unit 133. Then, the deposit balance according to the deposit by auto-charge may be displayed at a predetermined position on the product registration status screen. In this case, the deposit instruction button BT1 and the deposit balance confirmation button BT2 may not be displayed on the product registration status screen. With this configuration, customers do not need to perform any operations on the customer touch panel display unit 133, and even after a deposit has been made by auto-charge, no operations are required in particular in response to the use of an electronic money card, thereby preventing, for example, erroneous operations by customers.

[0100] In addition, when a product is being registered, if a customer holds electronic money card 300 over reader / writer 109 and reader / writer 109 and electronic money card 300 are able to communicate with each other, it may be assumed that the customer has expressed an intention to make payment using the electronic money card, and the payment process may be carried out as follows. That is, when the reader / writer 109 and the electronic money card 300 are able to communicate with each other, the POS register 100 provisionally registers the deposit balance of the electronic money card 300. Then, each time an item is registered, the POS register 100 updates the provisionally registered deposit balance by subtracting the price of the registered item from the provisionally registered deposit balance. When the updated provisionally registered deposit balance becomes too small to subtract the price of the registered item, the POS register 100 displays a deposit operation screen on the customer touch panel display unit 133 to prompt the customer to deposit money. When a deposit is made, the POS register 100 updates the deposit balance of the electronic money card according to the amount of the deposit, and also increases the provisionally registered deposit balance according to the deposit balance. When the subtotal operation is performed and the product registration is completed, the POS register 100 deducts the price of the registered product from the credit balance of the electronic money card. Note that, when the product is registered, the updated provisionally registered credit balance may be displayed on the screen each time the product is registered.

[0101] There is also known a POS system in which a registration device where a store clerk performs product registration operations and a payment device where a customer performs payment are separated. Such a POS system (product sales data processing system) can be configured, for example, as follows. In other words, when a customer wishes to make a payment with an electronic money card and the balance is insufficient to cover the cost, the customer offers to deposit money into the electronic money card to the store clerk operating the registration device. In parallel with the operation of registering the product, the store clerk performs an operation to provisionally register the deposit amount proposed by the customer in the registration device. The customer then pays the cash equivalent to the amount of the deposit he or she requested at the settlement device. The settlement device adds the paid cash to the deposit balance of the electronic money card to update it, and then deducts the registered product price from the updated deposit balance to complete the settlement.

[0102] In the above description, the POS register 100 of the present embodiment is used in a bakery. However, the POS register 100 of the present embodiment may be used in various types of stores other than a bakery.

[0103] In addition, a program for implementing the functions of the POS register 100 described above may be recorded on a computer-readable recording medium, and the program recorded on the recording medium may be read into a computer system and executed to perform the processing of the POS register 100 described above. Here, "reading a program recorded on a recording medium into a computer system and executing it" includes installing the program into a computer system. The "computer system" here includes hardware such as an OS and peripheral devices. The "computer system" may also include a plurality of computer devices connected via a network including the Internet, a WAN, a LAN, a dedicated line, and other communication lines. The "computer-readable recording medium" refers to portable media such as a flexible disk, an optical magnetic disk, a ROM, a CD-ROM, and a storage device such as a hard disk built into a computer system. In this way, the recording medium storing the program may be a non-transient recording medium such as a CD-ROM. The recording medium also includes a recording medium provided inside or outside the computer that can be accessed from a distribution server in order to distribute the program. The code of the program stored in the recording medium of the distribution server may be different from the code of the program in a format executable by a terminal device. That is, as long as it can be downloaded from a distribution server and installed in a form executable by a terminal device, the format in which it is stored in the distribution server does not matter. The program may be divided into multiple parts, downloaded at different times, and then combined on the terminal device, or each of the divided programs may be distributed by a different distribution server. Furthermore, the "computer-readable recording medium" includes a program that holds a program for a certain period of time, such as a volatile memory (RAM) inside a computer system that becomes a server or a client when a program is transmitted via a network. The program may also be a program for realizing part of the above-mentioned functions. Furthermore, the program may be a so-called difference file (difference program) that can realize the above-mentioned functions in combination with a program already recorded in the computer system.
