The store clerk operates the store clerk touch panel display unit 131 and keyboard 132 of the operation unit 103, the scanner 108, etc. while confirming the products placed on the tray, and registers the products and calculates the total price of the registered products. Let the POS register 100 do it. In response to such an operation, the CPU 151 in the POS register main unit 105 executes product registration processing. Further, the CPU 151 controls the store clerk touch panel display unit 131 to display the contents of the registered products, the total price of the registered products, and the like at any time. The CPU 151 also causes the touch panel display unit 133 for customer to display predetermined contents to be presented to the customer, such as the contents of the registered products and the total price of the registered products.

After confirming the total amount, the customer can make the payment (settlement) in cash as follows.
The customer inserts money (banknotes, coins) of an amount equal to or greater than the total amount from a banknote slot or a coin slot of the money slot 121a. As money is inserted as described above, the change dispenser 120 in the change dispenser unit 101 detects the type of the inserted money and the number of sheets for each type, and sends the inserted money information indicating the detection result to the POS register. It transmits to the main unit 105 . The CPU 151 of the POS register main unit 105 calculates the total amount of inserted money (deposit) based on the received inserted money information.
Note that the change dispenser 120 may calculate the deposit and transmit the calculated deposit to the POS register main unit 105 .

On the other hand, if the calculated deposit is larger than the total amount, CPU 151 in POS register main unit 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 banknote discharge port and the coin discharge port of the money insertion/discharge portion 121a. The customer receives the discharged money as change.
Hereinafter, the processing executed by the CPU 151 in response to cash settlement as described above will also be referred to as cash settlement processing.

In addition, the customer can also make payment (settlement) using the electronic money card 300 (an example of an electronic money storage medium). The electronic money storage medium is a storage medium having electronic money deposit/withdrawal (deposit and payment) functions. For example, RFID (Radio Frequency IDentification) or the like is adopted as the electronic money storage medium.
It should be noted that the payment in the present embodiment can be similarly performed using a smart phone, a mobile phone, or the like having a function as an electronic money storage medium. However, in order to make the explanation easier to understand, the case where payment is made with an electronic money card 300, which is a card-type electronic money storage medium, will be explained as an example.

When using the electronic money card 300 to pay the price, the customer performs an operation of selecting the use of the electronic money card 300 as the payment method on the clerk touch panel display unit 131 (e.g., selecting the use of the electronic money card). operation).
CPU 151 executes payment processing corresponding to the use of electronic money card 300 (hereinafter also referred to as electronic money payment processing) in response to the electronic money card use selection operation.
In other words, the CPU 151 causes the customer touch panel display unit 133 to display a payment-related screen corresponding to payment using the electronic money card 300 . The customer confirms the payment amount and the like presented on the displayed payment-related screen, holds the electronic money card 300 over the reader/writer 109 , and causes the reader/writer 109 and the electronic money card 300 to communicate with each other.
The reader/writer 109 reads out data necessary for settlement, such as deposited balance data, from the electronic money card 300 and outputs the read data to the CPU 151 . As settlement processing using the input data, the CPU 151 subtracts (subtracts) the subtotal amount from the deposit balance indicated by the input data, for example. The CPU 151 outputs to the reader/writer 109 write data including the value of the deposited balance after subtracting the subtotal amount.
The reader/writer 109 writes the input write data to the electronic money card 300 . As a result, the deposit balance in the electronic money card 300 decreases according to the price of the product purchased by the customer. In this way, the payment is made with the electronic money card 300. FIG.

By using the POS register 100 of the present embodiment in this manner, the customer and the store clerk can face-to-face the transaction regarding the bread purchased by the customer. In addition, in the case of the POS register 100 of the present embodiment, payment and receipt of change are performed between the customer and the money insertion/ejection unit 121a, and money is not handed over between the clerk and the customer. . In other words, the store clerk does not have to handle cash, electronic money card 300, or the like. As a result, the store clerk does not have to hold the bread with cash or the electronic money card 300, thereby improving hygiene.

In addition, the POS register 100 in this embodiment calculates the subtotal of the registered products until the customer's transaction corresponding to product registration is completed. During the period (product registration period) until the instructed subtotal operation is accepted, the customer's operation of depositing (charging) the electronic money card 300 can be accepted and the deposit processing can be executed.
That is, depending on the POS register of the present embodiment, the customer who has registered the product can deposit money into the electronic money card 300 in parallel with the operation of registering the product by the store clerk.
In the case where the store clerk does not register the merchandise and deposit the money into the electronic money card 300 at the same time, when the customer attempts to deposit the money into the electronic money card 300, the customer must complete the registration of the merchandise first and then the subtotal is made. After that, the clerk requests the payment to the electronic money card 300 and has the payment to the electronic money card 300 performed. After that, the customer uses the electronic money card 300 to which the money has been deposited to make a payment. In this case, the payment to the electronic money card 300 is performed between the registration of the product and the payment using the electronic money card 300, which prolongs the accounting.
On the other hand, in the present embodiment, since the electronic money card 300 is also charged while the product is being registered, settlement using the electronic money card 300 can be made immediately after the product is registered. can move to In other words, according to this embodiment, even if the electronic money card 300 is charged at the time of accounting, the accounting can be completed in a short period of time.

A configuration for enabling payment to the electronic money card 300 when merchandise is being registered in the POS register 100 of the present embodiment will be described below.
First, FIG. 6 shows an example of a product registration status screen, which is one of the settlement-related screens displayed on the customer touch panel display unit 133, and is displayed when a store clerk is registering products. there is

Further, a deposit instruction button BT1 and a deposit balance confirmation button BT2 are arranged on the product registration status screen.
The deposit instruction button BT1 is a button operated by the customer to instruct the electronic money card 300 to deposit money. Also, the deposit balance confirmation button BT2 is a button operated by the customer to instruct 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 determined, that is, while the product is being registered. A deposit instruction button BT1 and a deposit balance confirmation button BT2 are arranged on the product registration status screen. As a result, in this embodiment, the customer can perform an operation for depositing money into the electronic money card 300 or checking the deposit balance of the electronic money card 300 when the merchandise is being registered.

Here, a case is taken as an example where the customer notices that the amount of money deposited in the electronic money card 300 is low during registration of merchandise and wants to deposit money in the electronic money card 300 . In this case, while the product is being registered, the customer touches the deposit instruction button BT1 arranged on the product registration status screen displayed on the touch panel display unit 133 for the customer. to perform a touch operation. Then, the customer holds the electronic money card 300 that he or she possesses over the reader/writer 109 to allow communication between the reader/writer 109 and the electronic money card 300 .
As described above, when the deposit instruction button BT1 is touched and communication between the reader/writer 109 and the electronic money card 300 becomes possible, the customer touch panel display unit 133 changes the product registration status screen to the deposit operation screen. display.

FIG. 7 shows an example of a deposit operation screen displayed on the touch panel display unit 133 for customer.
A deposit balance display area AR11 is arranged on the deposit operation screen of FIG. The deposited balance of the electronic money card 300 is displayed in the deposited balance display area AR11. The deposited balance of the electronic money card 300 before the deposit is displayed in the deposited balance display area AR11 at the stage where the deposit has not yet been made. The figure shows an example in which "120 yen" is displayed as the deposit balance of the electronic money card 300 before deposit.

Also, on the deposit operation screen, deposit amount selection buttons BT11, BT12, BT13 and BT14 are arranged. Deposit amount selection buttons BT11, BT12, BT13, and BT14 are buttons for selecting the amount of money to be deposited into the electronic money card 300, respectively.
A customer who intends to deposit money into the electronic money card 300 touches a deposit amount selection button indicating the amount of money the customer wants to deposit, from among the deposit amount selection buttons BT11, BT12, BT13 and BT14. The CPU 151 sets the amount corresponding to the touch-operated deposit amount selection button as the deposit amount.

After the touch operation on the deposit amount selection button, the customer inserts cash equivalent to the deposit amount selected by the touch operation on the deposit amount selection button into the electronic money card 300 in the money insertion/ejection unit 121a. Insert into the mouth or coin slot.
As an example, when the customer wants to deposit 5000 yen, the customer touches the deposit amount selection button BT12. Then, 5000 yen worth of cash is thrown into the banknote slot or coin slot of the money slot 121a.

A deposit amount display area AR12 is arranged on the deposit operation screen. The amount of cash deposited by the customer is displayed in the deposited amount display area AR12.
The amount displayed in the deposit amount display area AR12 indicates 0 yen when the deposit operation screen is initially displayed. After the touch operation is performed on the deposit amount selection button, when the customer inserts cash into the banknote slot or coin slot of the money insert/eject unit 121a, the deposit amount is The amount displayed in the display area AR12 increases. In this case, when the amount of the inserted cash reaches the selected deposit amount in response to the operation of the deposit amount selection button, the selected deposit amount is displayed in the deposit amount display area AR12. will not accept any more cash deposits.

Alternatively, in the deposit amount display area AR12, the deposit amount selected in response to the operation of the deposit amount selection button is presented in response to the operation of the deposit amount selection button, and then the customer uses the money insertion/ejection unit 121a. The remaining deposit amount (amount obtained by subtracting the deposited amount from the selected deposit amount) may be displayed as the cash is deposited. In this case, when the amount of the inserted cash reaches the amount of money selected in response to the operation of the money amount selection button, the money amount display area AR12 indicates 0 yen. It will be in a state not to accept the deposit of cash above.
Also, the deposited balance displayed in the deposited balance display area AR11 may be increased according to the amount of cash deposited.

The CPU 151 controls the display in the deposited amount display area AR12 and the deposited balance display area AR11 in accordance with the operation of the deposited amount selection button and the insertion of cash into the money insertion/ejection unit 121a.
That is, the CPU 151 recognizes the amount of money to be paid by inputting an operation signal corresponding to the operation of the money amount selection button from the customer touch panel display section 133 . Further, information indicating the denomination and number of cash inserted into the money insertion/ejection unit 121a is transmitted from the change dispenser 120 to the CPU 151. FIG. The CPU 151 calculates the deposited cash based on the denomination and number of cash received from the change machine 120 . The CPU 151 can display the amount of money in each of the deposited amount display area AR12 and the deposited balance display area AR11 by using the recognized deposited amount and the calculation result of deposited cash.

Then, at the stage when the cash deposit corresponding to the deposit amount selected by operating the deposit amount selection button is completed, the deposit balance of the electronic money card 300 before this deposit is displayed in the deposit balance display area AR11. The deposit amount with the amount added is displayed.
As a specific example, if the current deposit amount is 5000 yen, 5120 yen is displayed in the deposit balance display area AR11 at the stage where the cash deposit is completed.
After confirming that the deposit balance displayed in the deposit balance display area AR11 is correct, the customer operates the "return" button BT16 on the deposit operation screen. In response to the operation of the "return" button BT16, the customer touch panel display unit 133 switches to display the product registration status screen of FIG. When the display is switched to the product registration status screen in this way, the last registered product is reflected in the registered product display area AR1, and the total price display area AR2 displays the The number of registered products and the total price are displayed.
The "return" button BT16, for example, causes the deposit operation screen to be displayed. It can also be operated in such cases.

Further, for example, after operating the deposit amount selection button on the deposit operation screen, if the customer wishes to interrupt the deposit to the electronic money card 300 during the process of depositing cash, etc., The "cancel" button BT15 should be operated.
In response to the operation of the "cancel" button BT15, the CPU 151 suspends the deposit processing thus far. Specifically, the CPU 151 ejects the cash deposited so far from the money insertion/ejection unit 121a, and switches the display on the customer touch panel display unit 133 to the product registration status screen.

In addition, in a state in which product registration has been performed and the product registration status screen (FIG. 6) is displayed on the customer touch panel display unit 133, when the customer wishes to check the balance of payment in the electronic money card 300, performs a touch operation on the deposit balance confirmation button BT2. The customer places the electronic money card 300 over the reader/writer 109 so that the reader/writer 109 and the electronic money card 300 can communicate with each other.

As described above, when the touch operation is performed on the deposit balance confirmation button BT2 and the reader/writer 109 and the electronic money card 300 become communicable, the display on the customer touch panel display unit 133 changes from the product registration status screen. Switch to the payment balance confirmation screen.
FIG. 8 shows an example of the deposit balance confirmation screen. A received balance display area AR21 is arranged on the received balance confirmation screen of FIG. The deposited balance of the electronic money card 300 is displayed in the deposited balance display area AR21. The electronic money card 300 whose deposited balance is displayed in the deposited balance display area AR21 is the electronic money card 300 whose data has been read from the reader/writer 109 by holding it over the reader/writer 109 .

In addition, 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 deposit to the electronic money card 300 . For example, when the customer wants to deposit money into the electronic money card 300 because the deposit balance displayed in the deposit balance display area AR21 of the deposit balance confirmation screen is smaller than expected, the customer touches the deposit instruction button BT21. should be done.
That is, when it is determined that it is necessary to check the deposited balance on the deposited balance confirmation screen and deposit money into the electronic money card 300, the deposit instruction operation can be performed from the same deposited balance confirmation screen. In other words, the customer does not have to go through the troublesome procedure of returning the display on the customer touch panel display section 133 from the deposit balance confirmation screen to the product registration status screen and operating the deposit instruction button BT1.

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 in FIG. 8 to the deposit operation screen in FIG.
Then, the customer can deposit the necessary amount of money by performing the same operation as described above on the displayed deposit operation screen. When the payment to the electronic money card 300 is completed, the display on the customer touch panel display section 133 returns to the product registration status screen of FIG. 6 also in this case. Even when the display is switched to the product registration status screen in this way, the last registered product is reflected in the registered product display area AR1, and the total price display area AR2 shows the The number of registered products and the total price are displayed.
Also, if the customer wants to return to the product registration status screen without depositing money into the electronic money card from the state where the deposit balance confirmation screen is displayed, the customer can operate the "return" button BT22.

When the product registration is completed, the clerk performs an operation for outputting a subtotal (subtotal operation: for example, operation of a subtotal button on the clerk touch panel display unit 131 or keyboard 132). In response to the subtotal operation, the touch panel display unit 133 for customer displays a settlement guide screen, which is one of the settlement-related screens.
FIG. 9 shows an example of a settlement guidance screen. A payment amount presentation area AR31 is arranged on the settlement guide screen of FIG. In the payment amount presentation area AR31 in the figure, the number of commodities registered corresponding to the customer and the total amount of the registered commodities are displayed. The total amount displayed in the payment amount presentation area AR31 is the price to be paid by the customer.

The customer can make payment (settlement) with either cash or the electronic money card 300 .
First, when making a payment in cash, the customer inserts cash as a price into the money insertion/ejection unit 121a while the payment guidance screen is being displayed.
When cash is inserted into the money insertion/discharge unit 121a in this way, the CPU 151 determines that payment by cash has been selected as the payment method, and performs payment processing corresponding to the inserted cash (payment processing for cash). .

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 guidance 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 payment processing corresponding to the electronic money card 300 (electronic money payment processing). .

When the electronic money payment selection button BT31 is operated and electronic money payment processing is to be performed, the customer touch panel display unit 133 changes from the payment guidance screen shown in FIG. 9 to the electronic money card usage guidance screen shown in FIG. is displayed.
A payment amount presentation area AR41 is arranged on the electronic money card usage guidance screen. In the payment amount presentation area AR41, similarly to the payment amount presentation area AR31 on the settlement guidance screen, the number of products registered for the customer and the total price of the registered products are displayed.
Further, on the electronic money card use guidance screen, guidance is displayed to prompt the customer to hold the electronic money card 300 over the reader/writer 109 so that the electronic money card 300 can communicate with the reader/writer 109 . .

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 electronic money settlement processing.
In other words, the reader/writer 109 reads out data necessary for settlement, such as data of the deposit balance, from the electronic money card 300 and outputs the read data to the CPU 151 . Therefore, the CPU 151, for example, subtracts the subtotal amount from the deposited balance indicated by the input data, and controls the reader/writer 109 to write the amount after deduction as the deposited balance.

If payment using the electronic money card is not normally performed due to a failure of the reader/writer 109 or the like, the customer touches the clerk call button BT41 arranged on the electronic money card usage guide screen to call the clerk. can be called. When the clerk call button BT41 is operated, for example, the clerk is informed that the clerk has been called by the customer, for example, by performing a notification on the clerk touch panel display unit 131 or the like.

When the electronic money payment processing is completed, the display on the touch panel display unit 133 for customer switches from the electronic money card usage guidance screen of FIG. 10 to the electronic money payment completion screen of FIG.
In the electronic money settlement completion screen, a payment amount presentation area AR51, a pre-settlement balance presentation area AR52, and a post-settlement balance presentation area AR53 are arranged.
In the payment amount presentation area AR51, the number of commodities to be settled and the total amount (price to be paid by the customer) are displayed.
In the pre-settlement balance presentation area AR52, the deposited balance of the electronic money card 300 before settlement corresponding to the use of the electronic money card is performed.
In the post-settlement balance presentation area AR53, the deposited balance of the electronic money card 300 after the settlement corresponding to the use of the electronic money card is performed.
The customer can check whether the settlement processing result is correct by looking at the contents displayed in the payment amount presentation area AR51, the pre-settlement balance presentation area AR52, and the post-settlement balance presentation area AR53.
The electronic money settlement completion screen also displays a message for the customer to receive a receipt showing the settlement processing result.

Next, an example of a processing procedure executed by the POS register 100 of this embodiment will be described with reference to the flowchart of FIG. 12 .
Step S101: The CPU 151 in the POS register 100 waits for the first (first) product registration operation corresponding to one transaction. The product registration operation includes an operation performed by the store clerk on the store clerk touch panel display unit 131 and the keyboard 132, an operation for reading the barcode attached to the product by the scanner 108, and the like.
Step S102: In response to the first product registration operation corresponding to step S101, the CPU 151 performs product registration processing for the product targeted for the first product registration operation. The product registration process is a process of acquiring, for example, the number of products to be registered, the product name, the price (unit price), and the like.
Step S103: In addition, the CPU 151 causes the customer touch panel display section 133 to display a product registration status screen in response to the first product registration operation corresponding to step S101. Note that the CPU 151 performs display control to display a screen showing the registration status of product registration on the clerk touch panel display unit 131 in accordance with the product registration operation. However, in the same figure, for the convenience of facilitating the explanation of the processing of the POS register 100, the illustration of the display control processing corresponding to the clerk touch panel display unit 131 is omitted.

Step S104: After executing the processing of steps S102 and S103 corresponding to the first product registration operation as described above, the CPU 151 determines whether or not the second and subsequent product registration operations have been performed.
Step S105: When it is determined in step S104 that the product registration operation has been performed for the second time or later, the CPU 151 executes product registration processing according to the product registration operation performed in response to step S104.
At this time, if the product registration status screen is displayed on the customer touch panel display unit 133, the CPU 151 reflects the results of the product registration processing performed so far in the registered product display area AR1 and the total amount display area AR2. Let

Step S106: After completing the product registration process in step S105, or when it is determined in step S104 that the product registration operation has not been performed, the CPU 151 determines whether or not the payment confirmation instruction operation has been performed. judge. Here, the payment confirmation instruction operation means that the payment balance confirmation button BT2 arranged on the product registration status screen is touched while the product registration status screen of FIG. 6 is being displayed.

Step S107: When the payment confirmation instruction operation is performed, the CPU 151 executes processing for displaying the payment balance confirmation screen of FIG. At this time, the CPU 151 acquires the deposit balance included in the data read from the electronic money card 300 by the reader/writer 109 . The CPU 151 causes the touch panel display unit 133 for customer to display a payment balance confirmation screen in which the amount of the acquired payment balance is displayed in the payment balance display area AR21.

Step S108: After displaying the deposited balance confirmation screen in step S107, the CPU 151 determines whether or not an operation to terminate the display of the deposited balance confirmation screen has been performed. The operation for terminating the display of the deposited balance confirmation screen is the operation for the "return" button BT22 on the deposited balance confirmation screen.

Step S109: If the operation to terminate the display of the deposit balance confirmation screen has not been performed, the CPU 151 determines whether or not a deposit instruction operation has been performed. The deposit instruction operation determined in step S109 is an operation on the deposit instruction button BT21 on the deposit balance confirmation screen. If the deposit instruction operation has not been performed, the CPU 151 returns the process to step S108.

Step S110: In addition, when the payment balance confirmation instruction operation is not performed in the previous step S106, the CPU 151 determines whether or not the payment instruction operation is performed while the product registration status screen is displayed. The deposit instruction operation determined in step S110 is an operation on the deposit instruction button BT1 on the product registration status screen.

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 deposit processing.
In the deposit process, the CPU 151 causes the customer touch panel display section 133 to display the deposit operation screen of FIG. Then, as described with reference to FIG. 7, when cash corresponding to the deposit amount selected by the touch operation on the deposit amount selection button is inserted into the money insertion/ejection unit 121a, the CPU 151 changes the deposit balance of the electronic money card 300. is increased according to the deposit amount.

Step S112: When the deposit processing in step S111 is completed, or when an operation is performed to terminate the display of the deposit balance confirmation screen in step S108, the CPU 151 displays the Control to switch from the display of the operation screen or the deposit balance confirmation screen to the display of the product registration status screen.

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

Step S114: On the other hand, when it is determined in step S113 that a subtotal operation has been performed, the CPU 151 causes the customer touch panel display section 133 to display a payment guide screen (FIG. 9).
Step S115: With the settlement guide screen displayed, the CPU 151 determines whether electronic money or cash has been selected as the settlement method (payment method).

Step S116: When the customer inserts cash into the money insertion/ejection unit 121a while the settlement guidance screen is displayed, the change machine 120 notifies the CPU 151 of the fact that the cash has been inserted (cash insertion notification). sent to.
When the CPU 151 receives the cash-insertion notification, the CPU 151 determines that cash has been selected as the settlement method. Therefore, the CPU 151 in this case executes cash settlement processing. In other words, when 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 showing the settlement processing result.
Further, when the amount of the inserted cash is larger than the price, control is performed to discharge the change from the money input/output unit 121a, and then a receipt showing the settlement processing result including the processing corresponding to the change is generated. The printer 107 is caused to print.

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 determines that the payment method using electronic money has been selected. Therefore, the CPU 151 in this case performs electronic money settlement processing. Under the electronic money payment processing, the CPU 151 causes the customer touch panel display unit 133 to display an electronic money card use guidance screen, and displays an electronic money payment completion screen upon completion of payment.

By performing the processing as described above, the customer will be able to By performing the operation, it is possible to deposit money into the electronic money card 300 and check the deposit balance of the electronic money card 300 .

Next, a modified example of this embodiment will be described. In the processing procedure shown in FIG. 12, regardless of whether or not the electronic money card 300 is charged while the product is being registered, the customer uses the electronic money card 300 to make a payment. , an operation to select payment with the electronic money card 300 (an operation to the electronic money payment selection button BT31) is performed on the payment guidance screen.
However, the fact that the electronic money card 300 is charged while the merchandise is being registered can be interpreted as the customer intending to make a payment with the electronic money card 300 continuously. Considering this, even if the electronic money card 300 is charged while the product is being registered, the payment with the electronic money card 300 is selected on the payment guidance screen. It can be said that it takes unnecessary time and effort to make the customer perform the operation.
Therefore, as a modification, if payment is made to the electronic money card 300 after the product registration is started and before the subtotal operation is performed, electronic money compatible settlement processing is performed. do. In other words, from the customer's point of view, if the electronic money card 300 is charged during product registration, the POS register 100 shifts to electronic money settlement processing as it is when the subtotal operation is performed. At this time, when the subtotal operation is performed on the touch panel display unit 133 for customer, for example, instead of the settlement guidance screen (FIG. 9), the electronic money card use guidance screen (FIG. 10) is immediately displayed. In this case, the customer does not have to perform the operation of selecting payment with the electronic money card 300 (manipulating the electronic money payment selection button BT31) on the payment guidance screen.
It should be noted that the condition for transitioning to electronic money compatible settlement processing is not limited to the customer charging the electronic money card 300 . For example, the electronic money card 300 is placed on the reader/writer 109 while the electronic money card 300 is in a state in which communication is possible via the reader/writer 109 (checking the deposit balance or simply registering the product, In response to the fact that communication is possible via the reader/writer 109), the customer performs an operation ( The electronic money payment selection button BT31 may be deemed to have been operated, and execution of the cash payment processing may be prohibited, and the electronic money payment processing may be performed.

In order to realize the operation as described above, the following processing may be added in response to, for example, the case where it is determined in step S113 of FIG. 12 that a subtotal operation has been performed.
That is, the CPU 151 ensures that the electronic money card 300 is charged during the period from when the first product registration operation is performed in step S101 to when the subtotal operation is performed in step S113 (product registration period). It is determined whether or not the
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.
With the processing performed by the CPU 151 in this way, when the electronic money card 300 is charged during product registration, the customer selects the use of the electronic money card 300 as the payment method on the payment guidance screen. Settlement with the electronic money card 300 can be proceeded without performing any operation.

When the reader/writer 109 and the electronic money card 300 become communicable, when displaying the electronic money card balance, the display is changed from the product registration status screen to the payment balance confirmation screen. You can do it like this. Alternatively, the product registration status screen may be displayed without changing to the payment balance confirmation screen, and the payment balance may be displayed at a predetermined position on the product registration status screen.

Therefore, in the POS register 100 of the present embodiment, when processing the payment balance notification for the electronic money card set with the auto-charge function as described above, the confirmed payment balance is less than the execution amount. In this case, the customer may be urged to deposit money.

With such a configuration, the customer does not need to operate the touch panel display unit 133 for customer, and even after the payment is made by auto-charging, the customer does not need to perform any operation according to the use of the electronic money card. Therefore, for example, erroneous operations by customers can be prevented.

Further, when the electronic money card 300 is held over the reader/writer 109 by the customer while the product is being registered, and the reader/writer 109 and the electronic money card 300 become communicable, the electronic money The payment processing may be performed as follows, assuming that the customer has indicated his/her intention to use the card for payment.

After that, the POS register 100 updates the provisionally registered payment balance by subtracting the price of the registered product from the provisionally registered payment balance each time the product is registered. Then, when the balance of the payment of the updated provisional registration becomes small and it becomes impossible to deduct the price of the registered product, the POS register 100 displays a payment operation screen on the touch panel display unit 133 for customer. and prompt the customer to deposit money. When the money is deposited, the POS register 100 updates the deposited balance of the electronic money card according to the deposited amount, and also increases the temporarily registered deposited balance according to the deposited amount.
Then, 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 deposited balance of the electronic money card. It should be noted that the updated provisional registration balance may be displayed on the screen for each product registration together with the registration of the product.

Also known is a POS system in which a registration device for registering merchandise by a store clerk and a checkout device for customers to pay for products are separated from each other. Such a POS system (merchandise sales data processing system) can be configured as follows, for example.
In other words, when a customer uses an electronic money card to make a payment, if the balance of the payment is insufficient for the price, the customer asks the clerk who operates the registration device to deposit money into the electronic money card. The store clerk performs an operation of temporarily registering the deposit amount requested by the customer in the registration device in parallel with the operation of registering the product.
Then, the customer pays cash corresponding to the deposit amount previously offered at the settlement device. The settlement device adds the paid cash to the deposited balance of the electronic money card to update it, and then performs settlement by deducting the price of the registered commodity from the updated deposited balance.
