The POS system is provided in a store, for example. The POS system includes a registration device 20 and a settlement device 30. The number of the registration device 20 and the payment device 30 may be plural. The registration device 20 scans the barcode attached to the product purchased by the customer by the operation of the clerk. The registration device 20 registers the transaction information of the product in the storage unit based on the barcode data. The transaction information of the product may include, for example, transaction identification number, product identification number, and information indicating the number of products.

When the registration of the transaction information of the product is completed for the bar code of all the products purchased by the customer, the registration device 20 performs an operation input for declaring the completion of the registration of the transaction information of the product (for example, the completion key by the clerk). The bar code or the two-dimensional code is printed on the accounting ticket 40 (details will be described later with reference to FIG. 6), and the accounting ticket 40 is issued to the customer.

The customer who receives the checkout ticket 40 moves to the checkout device 30 and uses the scanner unit included in the checkout device 30 to read the barcode or two-dimensional code printed on the checkout ticket 40, and the customer himself pays the bill. By operating the operation keys of the device 30, the purchase price of the product (total price of the purchased products) determined by the transaction information is settled.

FIG. 2 shows a configuration example of the POS system by a block diagram. The POS system may further include a store controller 10 (upper management device). The POS system includes a store controller 10, an registration device 20 for N units (N is an integer of 1 or more), and a settlement device 30 for M units (M is an integer of 1 or more). The store controller 10, the registration device 20, and the settlement device 30 are connected via a LAN (Local Area Network) 11.

The store controller 10 stores product information (for example, the price of a product) in advance as product master data. The registration device 20 may register the transaction information of the product in the store controller 10 based on the read barcode data. That is, the store controller 10 may store transaction information and the like transmitted from the registration device 20.

The registration device 20 may include a registration device 20 that is not connected to the store controller 10 and a registration device 20 that is connected to the store controller 10 via the LAN 11.

First, the details of the registration device will be described.
FIG. 3 shows a configuration example of the registration device by a block diagram. The registration device 20 includes a CPU (Central Processing Unit) 201, a ROM (Read Only Memory) 202, a RAM (Random Access Memory) 203, a scanner unit 204, a display unit (for clerk) 205, and a display unit (customer). For) 205a, an operation unit 206, a communication unit 207, a buzzer 208, a receipt printing means 209, and a hard disk 210. Each of these parts is connected to each other via a bus.

The scanner unit 204 optically reads the barcode (product code) attached to the product.
The ROM 202 is a read-only memory, and stores a program for operating the registration device 20 in advance.

The CPU 201 is a central processing unit. The CPU 201 reads the program stored in the ROM 202 and expands it in the RAM 203. The CPU 201 controls each part of the registration device 20 by executing each step of the expanded program.

The CPU 201 registers the transaction information of the product in the RAM 203 or the hard disk 210 based on the barcode data read by the scanner unit 204. Further, the CPU 101 may register the transaction information of the product in the store controller 10 via the communication unit 207 based on the barcode data read by the scanner unit 204.

The CPU 201 specifies a settlement method (payment method) selected by the customer. For example, the CPU 201 identifies the settlement method selected by the customer based on the identification information indicating cash, credit card, electronic money, or gift certificate input by the clerk who operates the operation unit 206. Hereinafter, the information indicating the settlement method selected by the customer is referred to as "payment method information".

The customer can offer to the clerk who operates the registration device 20 that he / she wants to put the cash to be added to the change into the settlement device 30. In this case, the clerk who received the offer operates the operation unit 206 to input the settlement method information into the CPU 201. When the settlement method information input by the operation via the operation unit 206 indicates "cash addition", the CPU 201 sets the value indicating the cash addition flag to "valid".

Further, the CPU 201 controls the receipt printing means 209 so as to print a receipt in a format corresponding to the specified settlement method and issue the receipt. More specifically, the CPU 201 self-registers when the specified settlement method is a settlement method other than cash, for example, a settlement method using a gift certificate with the same face value as the purchase amount (no change payment is required). The receipt printing means 209 is controlled so as to print the detailed information of the product determined by the transaction information settled by the apparatus on the receipt and issue the receipt. That is, when the settlement method information operation-input via the operation unit 206 indicates a "credit declaration", an "electronic money declaration", or a "gift certificate", the CPU 201 executes the settlement process by the self-registration device. The receipt printing means 209 is instructed to issue a receipt on which the later detailed information is printed.

On the other hand, the CPU 201 controls the receipt printing means 209 to issue the accounting ticket 40 on which the transaction information is printed when the specified settlement method includes at least a cash settlement method. For example, when the specified settlement method is a settlement method using a gift certificate having a face value larger than the purchase price (change payment is required), the CPU 201 issues an accounting ticket 40 on which transaction information and the like are printed. The receipt printing means 209 is controlled. That is, when the settlement method information operation-input via the operation unit 206 indicates "cash" or "accounting ticket", the CPU 201 prints the information necessary for the customer to operate the settlement device 30 for settlement. Instruct the receipt printing means 209 to issue the accounting ticket 40.

Here, the CPU 201 may control the receipt printing means 209 so as to issue an accounting ticket 40 on which a barcode or a two-dimensional code including identification information indicating transaction information is printed. Further, the CPU 201 may control the receipt printing means 209 to issue an accounting ticket 40 on which a barcode (added) or a two-dimensional code including a cash addition flag is printed.

FIG. 7 is a flowchart showing an operation procedure of a registration device (see FIG. 3) that executes payment by a gift certificate. In order not to increase the number of banknotes or coins to be paid as change, the customer can offer to the clerk who operates the registration device 20 that he / she wants to put the cash to be added to the change into the settlement device 30. A customer who offers to put the cash to be added to the change into the checkout device 30 puts the cash to be added to the change generated by the gift certificate paid by the registration device 20 into the checkout device 30 and inputs the amount of the change. It can be adjusted to a good amount of money (for example, the last digit is the value 0 or the last two digits are the value 00).

(Step S1) The scanner unit 204 optically reads a barcode (product code) attached to the product by an operation by a store clerk. The CPU 201 registers the transaction information of the product in the RAM 203 based on the barcode data read by the scanner unit 204.

(Step S2) The CPU 201 acquires the gift certificate information (for example, the face value of the gift certificate paid by the customer) based on the operation input via the operation unit 206. Here, it is assumed that the change of the amount obtained by subtracting the purchase amount from the face value of the gift certificate paid by the customer has occurred.

For example, when the purchase amount is 801 yen and the face value of the gift certificate is 1000 yen, the change amount is 199 yen as the amount obtained by subtracting the purchase amount from the face value. If the amount of change is not adjusted to a good amount, 199 yen as change is, for example, 1 100 yen coin, 1 50 yen coin, 4 10 yen coins, 1 5 yen coin, and 1 A total of 11 coins consisting of 4 yen coins will be paid from the settlement device 30. On the other hand, if the amount of change to be finally paid is adjusted by adding 1 yen to the change before adjustment, 200 yen as the adjusted change will be settled with only two 100 yen coins. It will be paid from 30.

(Step S3) When the customer requests the clerk to put the cash to be added to the change into the checkout device 30, the clerk who operates the registration device 20 presses the cash addition key 550 (see FIG. 4 or FIG. 5). do. The CPU 201 determines whether or not the cash addition key 550 has been pressed based on the operation input via the operation unit 206. When the cash addition key 550 is pressed (step S3: Yes), the CPU 201 proceeds to step S4. On the other hand, when the cash addition key 550 is not pressed (step S3: No), the CPU 201 proceeds to the process in step S5.

(Step S4) The CPU 201 sets a value indicating the cash addition flag, which was initially set to invalid (for example, value 0), to "valid (for example, value 1)", and proceeds to step S5.
(Step S5) The CPU 201 determines whether or not the accounting key 540 or the accounting ticket key 520 is pressed based on the operation input via the operation unit 206. When the accounting key 540 or the accounting ticket key 520 is pressed (step S5: Yes), the CPU 201 proceeds to the process in step S6. On the other hand, when neither the accounting key 540 nor the accounting ticket key 520 is pressed (step S5: No), the CPU 201 proceeds to the process in step S9.

(Step S6) The CPU 201 determines whether or not the cash addition flag is valid. When the cash addition flag is valid (step S6: Yes), the CPU 201 proceeds to step S7. On the other hand, when the cash addition flag is invalid (step S6: No), the CPU 201 proceeds to the process in step S8.

(Step S7) The CPU 201 includes (adds) a cash addition flag to the transaction information, and barcodes the identification information indicating the transaction information. The CPU 201 may include (add) a cash addition flag in the transaction information and two-dimensionally code the detailed information of the product determined by the transaction information. Here, for example, when the data amount of the transaction information is less than the threshold value, the CPU 201 barcodes the identification information indicating the transaction information including the cash addition flag, and when the data amount of the transaction information is equal to or more than the threshold value. , The detailed information of the product determined by the transaction information including the value indicating the cash addition flag may be coded in two dimensions.

(Step S8) When the accounting ticket key 520 is pressed in step S5, the CPU 201 prints the accounting ticket 40 on which the barcode (see FIG. 6A) on which the identification information indicating the transaction information is printed is printed. It is issued from the receipt printing means 209. The communication unit 207 transmits and registers the transaction information to the store controller 10. The CPU 201 may have the receipt printing means 209 issue an accounting ticket 40 on which a two-dimensional code (see FIG. 6B) indicating the contents of the transaction information is printed. On the other hand, when the accounting key 540 is pressed in step S5, the communication unit 207 transmits the transaction information to the settlement device 30 selected by the settlement device selection key 530. In this case, the CPU 201 may have the selected settlement device 30 directly transmit transaction information from the communication unit 207.
