That is, when the shopper C who wants to make a payment using the gift certificate presents the gift certificate, the operator S receives the gift certificate from the shopper C, determines the type of the gift certificate, and determines the type of the gift certificate. From the plurality of gift certificate keys provided according to the type of gift certificate, the gift certificate key corresponding to the identified type is pressed. For example, the operator S who receives the gift certificate described as "○○ common gift certificate ¥ 1,000" from the shopper C presses the gift certificate key provided corresponding to the gift certificate and the gift certificate. By this operation, the operation unit 108 for the clerk supplies the key code of the pressed gift certificate key to the CPU 101, and the CPU 101 takes in the supplied key code and is provided corresponding to the gift certificate and the gift certificate. It is determined that the ticket key has been pressed. If the CPU 101 determines that the gift certificate key has been pressed (S2: YES), the process proceeds to step S3, and if the CPU 101 determines that the gift certificate key has not been pressed (S2: NO), step S4. Move on to processing.

In the process of step S3, the CPU 101 has a predetermined gift certificate identifier (for example, "90") and a predetermined type number (for example, gift certificate and) corresponding to the pressed gift certificate key. The gift certificate generates gift certificate information based on "01") and a numerical code (for example, "1000") of the amount of money supplied from the clerk operation unit 108, and stores the gift certificate information in the RAM 103.

Specifically, when the gift certificate is a gift certificate or gift certificate worth 1000 yen, the CPU 101 uses, for example, a predetermined gift certificate identifier "90" and the pressed gift certificate or gift certificate. FIG. 5 shows FIG. 5 based on the type number “01” determined in advance corresponding to the associated gift card key and the numerical code “1000” of the amount of money supplied from the clerk operation unit 108. The gift certificate information "9001000000001000" to be shown is generated and stored in the RAM 103.
When the gift certificate is a coupon ticket with a discount of 500 yen, the CPU 101 corresponds to, for example, a predetermined gift certificate identifier "90" and a gift certificate key associated with the pressed coupon ticket. Then, based on the predetermined type number "02" and the numerical code "500" of the amount of money supplied from the clerk operation unit 108, the coupon information "9002000000000500" shown in FIG. 5 is generated. Then, it is stored in the RAM 103.

Next, in step S4, the CPU 101 determines whether or not the current total key of the store clerk operation unit 108 has been pressed. That is, the operator S has completed the product registration of the purchased product of the shopper C, and if there is a gift certificate desired to be used, the registration of the gift certificate has been completed, or the gift certificate from the shopper C When it is confirmed that there is no offer to use, the current total key provided on the clerk operation unit 108 is pressed. By this operation, the clerk operation unit 108 supplies the key code of the pressed current total key to the CPU 101, and the CPU 101 takes in the supplied key code and determines that the current total key has been pressed. When the CPU 101 determines that the current total key has been pressed (S4: YES), the CPU 101 generates a two-dimensional code based on the purchased product information and the gift certificate information stored in the RAM 103, and proceeds to step S5. On the other hand, when the CPU 101 determines that the current total key has not been pressed (S4: NO), the process proceeds to step S1.

In step S5, the CPU 101 includes date and time information of the clock, a transaction identification number represented by a number increasing by 1 for each transaction, the number of purchased products, which is the number of product identification information, and a two-dimensional code. Is supplied to the printing unit 111. Then, the printing unit 111 prints the supplied information and outputs it as an accounting receipt.

Next, the settlement process by the settlement device 20 will be described. FIG. 9 is a flowchart showing a procedure of the settlement process executed by the settlement device 20. When the CPU 201 reads the settlement program stored in the ROM 203, expands it into the RAM 203, and starts executing the expanded settlement program, the settlement device 20 starts the settlement process according to the flowchart of the figure.
The settlement device 20 stores the product data file supplied from the store controller in the RAM 203 in advance before executing the settlement process.

In step S11, when the two-dimensional code printed on the accounting receipt is readablely positioned in the two-dimensional code reading area of the scanner unit 204 by the action of the shopper C himself, the scanner unit 204 displays the two-dimensional code. The two-dimensional code recording information that is read and recorded in the two-dimensional code is extracted and stored in the RAM 203.
Specifically, for example, the scanner unit 204 reads the two-dimensional code printed on the accounting receipt, and includes the product identification information "49123456789666" and "491234567888" recorded in the two-dimensional code, and the gift certificate information. "9001000000001000" is extracted and stored in the RAM 203. As a result, the memory map shown in FIG. 6 is expanded in the RAM 203.

Next, the CPU 201 extracts the product identification information from the two-dimensional code recording information stored in the RAM 203, and uses the extracted product identification information as a search key to sell the product name and the product from the data table of the product data file stored in the RAM 203 in advance. Extract with price. As a method for extracting the product identification information, for example, the CPU 201 extracts only the data in which the upper two-digit number indicates the product identification information from the two-dimensional code recording information stored in the RAM 203. Next, the CPU 201 counts the extracted product identification information having the same number (however, if none of the extracted product identification information has the same number, the counting result is "1"), and counts each product identification information. The result (that is, the number of purchases), the product name, and the selling price are stored in the RAM 203. Then, the CPU 201 calculates the total amount of the selling price and stores it in the RAM 203 as the total purchase amount.

Next, in step S12, the CPU 201 searches for the gift certificate information from the two-dimensional code recording information stored in the RAM 203, and when the gift certificate information is detected (S12: YES), the amount is extracted from the gift certificate information. do. As a method of extracting the gift certificate information, for example, the CPU 201 extracts only the data in which the upper two-digit number indicates the gift certificate information from the two-dimensional code recording information stored in the RAM 203. Next, the CPU 201 calculates the total amount of the amount of one or more gift certificate information, stores it in the RAM 203 as the total amount of the gift certificate, and proceeds to the process of step S13.
On the other hand, when the CPU 201 does not extract the gift certificate information from the two-dimensional code recording information stored in the RAM 203 (S12: NO), the total amount of the gift certificate is stored in the RAM 203 as “0”, and the process proceeds to step S24.

In step S13, the CPU 201 calculates the difference between the total purchase amount and the total gift certificate amount stored in the RAM 203 (total purchase amount-total gift certificate amount), and the difference is "0" or a positive integer (S13). : YES), the difference is stored in the RAM 203 as the payment request amount, and the process proceeds to step S14. On the other hand, when the calculated difference is a negative integer (S13: NO), the CPU 201 stores the difference as a refund amount in the RAM 203, and proceeds to the process of step S22.

In step S14, the CPU 201 includes information on the product name of the purchased product of shopper C, the number of purchases, the total purchase amount, the total amount of gift certificates, and the payment request amount stored in the RAM 203, and also includes an accounting key. The accounting menu (a) including the image of the GUI operation button of the above is supplied to the display unit 205. Then, the display unit 205 displays the accounting menu (a). The accounting key, which is a GUI operation button, has the function of the customer operation unit 206.
FIG. 10 shows a display example of the accounting menu (a) displayed by the display unit 205. As shown in the figure, in the process of step S14, the display unit 205 displays the menu 50a. On the left side of the menu 50a, the product name and the number of products purchased by shopper C are displayed for each product, and on the right side of the menu 50a, the total purchase price, the total gift certificate amount, and the payment request amount are displayed. Information including the accounting key 51 and information prompting the user to press the accounting key 51 (“press the accounting key”) is displayed.

In step S15, when the accounting key 51 is touched by the shopper C, the customer operation unit 206 supplies the CPU 201 with an operation signal indicating that the accounting key 51 has been touched, and the CPU 201 receives the operation signal. Then, the process proceeds to step S16.
Next, in step S16, the CPU 201 supplies the display unit 205 with a menu including the payment request amount stored in the RAM 203 and the image of the GUI operation button of the settlement key.
Then, the display unit 205 displays the menu. The settlement key, which is a GUI operation button, has the function of the customer operation unit 206.
FIG. 11 shows a display example of the menu displayed by the display unit 205. As shown in the figure, in the process of step S16, the display unit 205 displays the menu 60a. The menu 60a displays information including the payment request amount to the shopper C, the settlement key 61, and information prompting the customer to press the settlement key 61 (“Please insert into the change machine and press the settlement key”). Will be done.

Next, in step S17, when the shopper C inserts money according to the payment request amount into the slot of the change machine 210, the change machine 210 deposits the inserted money and transfers the deposited amount to the CPU 201.

Next, in step S18, the CPU 201 supplies the deposit amount stored in the RAM 203 to the display unit 205, and the display unit displays the deposit amount. Specifically, for example, when the deposit amount is "1000", the display unit 205 displays the menu 60b shown in FIG.
Next, in step S19, when the checkout key 61 is touched by the shopper C, the customer operation unit 206 supplies the CPU 201 with an operation signal indicating that the checkout key 61 has been touched, and the CPU 201 operates the operation. Upon receiving the signal, the process proceeds to step S20.

In step S20 executed after the process of step S19, the CPU 201 calculates the difference (payment amount-payment request amount) between the payment request amount and the deposit amount stored in the RAM 203, and the difference is "0" or positive. If it is an integer (that is, if the change amount is 0 yen or there is a change amount), the difference is stored in the RAM 203 as the change amount. Next, the CPU 201 notifies the change machine 210 of the change amount. Upon receiving the notification of the change amount, the change machine 210 withdraws the change amount and discharges it to the discharge port. Then, the change machine 210 supplies the CPU 201 with a notification of the completion of the change process. Next, the CPU 201 supplies the change amount stored in the RAM 203 to the display unit 205, and the display unit displays the change amount. Specifically, when the change amount is "500", the display unit 205 displays the menu 70a shown in FIG.

In the process of step S20, when the difference calculated by the CPU 201 is a negative integer (that is, when there is a shortage amount), although not shown in the flowchart of FIG. 9, the difference is newly paid. The requested amount is stored in the RAM 203, and the process returns to the process of step S16.
