Description

The present invention relates to a checkout system and a program.

At checkout counters in stores that sell merchandise, where the purchases are registered and settled, payment is sometimes made using gift certificates. In conventional checkout counters equipped with a register that registers and settles the purchased merchandise operated by a store clerk, the store clerk receives a gift certificate from a shopper, registers the necessary information such as the amount in the register, registers the purchased merchandise, and then performs a settlement process based on the registered gift certificate amount and the registered purchase amount (see, for example, Patent Document 1). Recently, self-service registers have also been proposed to reduce labor costs and eliminate waiting times at the register.

FIG.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.
[First embodiment]
1 is a perspective view showing a checkout system according to a first embodiment of the present invention installed and operating on a store floor. As shown in the figure, the checkout system 100 includes five product registration devices 10 and six payment devices (automatic payment devices) 20. The product registration devices 10 are installed at a product registration counter 11, and the two payment devices 20 are installed at a payment counter 21.

In addition, a store controller (not shown) is installed in the back yard of the store where the checkout system 100 is installed. The store controller and each of the five product registration devices 10 and six payment devices 20 of the checkout system 100 are communicatively connected via a LAN (Local Area Network) (not shown). The store controller is a computer device, and records a product data file including a data table related to the products handled by the store. The store controller updates the product data file, for example, daily, depending on the sales status and purchasing status of the products, and supplies the product data file to each of the five product registration devices 10 and the six payment devices 20. Details of the product data file will be described later. The store controller may be part of a POS (Point Of Sales) system or connected to the POS system.

The product registration device 10 is a device that registers product identification information of the product (purchased product) purchased by shopper C and, if shopper C wishes to settle the bill using a gift certificate, the gift certificate information of the gift certificate, according to the operation of operator S, and converts the registered product identification information and gift certificate information into two-dimensional codes and prints them on an accounting receipt.
The product identification information is information for identifying a product that is recorded in a barcode that is attached, pasted, printed, etc. to the product. The product identification information is, for example, a 13-digit JAN (Japanese Article Number) code.

A gift certificate is a ticket that has monetary value and can be used for settlement at the checkout system 100. For example, gift certificates are gift certificates, coupon tickets, and service tickets. Gift certificates and gift certificates include, for example, general-purpose tickets such as gift cards issued by credit card companies and the like, common tickets such as common gift certificates, book cards, stationery tickets, and common beer tickets that can be used nationwide or in a specific region, and unique tickets issued independently by manufacturers, stores, companies, etc. Coupon tickets are, for example, tickets that state a discount amount or a discount amount. Service tickets are, for example, tickets that state that a specific quantity of a specific product will be provided free of charge.
In this embodiment, information regarding the available amount obtained from the gift certificate in a transaction, the amount of the service target product, etc., and information identifying the type of gift certificate are called gift certificate information, and this gift certificate information is payment information used for payment by shopper C. In particular, gift certificates, discount coupons, etc., constitute all or part of the payment amount, and therefore become the payment information of shopper C.
In addition to gift certificates, the product registration device 10 may be provided with a credit card settlement function, and credit card payment information may be converted into a two-dimensional code together with the product identification information.

The product registration device 10 is installed at the product registration counter 11 so that the shopper C and the operator S stand facing each other across the product registration counter 11. Therefore, when the shopper C wishes to use a gift certificate, the shopper C and the operator S, who are standing facing each other, can easily exchange the gift certificate. Similarly, the operator S and the shopper C can easily exchange the accounting receipt printed and output by the product registration device 10.

The settlement device 20 reads the two-dimensional code printed on the accounting receipt by the operation of shopper C who is holding the accounting receipt, and extracts the two-dimensional code recorded information recorded in the two-dimensional code. Then, based on the product identification information contained in the extracted two-dimensional code recorded information and a data table of a product data file previously stored in the settlement device 20, the settlement device 20 extracts the product names and sales prices of the products purchased by shopper C from the data table, and calculates the total purchase amount of the extracted sales prices. The total purchase amount is the sum of the sales prices of all the products purchased by shopper C.

If the two-dimensional code recorded information contains gift certificate information, the settlement device 20 calculates the total gift certificate amount based on the gift certificate information. The total gift certificate amount is the total amount used in the transaction for all gift certificates used by shopper C in that transaction. If the two-dimensional code recorded information does not contain gift certificate information, the settlement device 20 sets the total gift certificate amount to 0 yen. The settlement device 20 also calculates the payment request amount or refund amount based on the calculated total purchase amount and total gift certificate amount. The payment request amount is the difference (total purchase amount - total gift certificate amount) when the total gift certificate amount is less than the total purchase amount. The refund amount is the difference (total gift certificate amount - total purchase amount) when the total gift certificate amount is more than the total purchase amount.

The settlement device 20 then displays, in a checkout menu, the names of the products purchased by shopper C, the total purchase amount, the total gift certificate amount, the requested payment amount or refund amount, and information prompting shopper C to perform the settlement operation. The settlement device 20 also includes a change dispenser and processes the change for the money inserted by shopper C. After processing the change, the settlement device 20 also prints and outputs a receipt.

The checkout counter 21 is preferably placed at the destination where shopper C moves from the product display floor via the product registration counter 11. In the store floor shown in FIG. 1, the product registration counter 11 and the checkout counter 21 are installed so that shopper C moves from the front left to the back right in the perspective view. After shopper C receives the accounting receipt printed by the product registration device 10 from the operator S, he or she can move to any of the three checkout counters 21 he or she desires, for example, an empty checkout counter 21, to make the payment. In other words, in the checkout system 100, the checkout device 20 that can be used is not limited by the product registration device 10 that printed the accounting receipt.

The number of product registration devices 10 and the number of settlement devices 20 included in the checkout system 100 are not limited to five and six, but are determined, for example, according to the size and costs of the store. In this embodiment, for the sake of simplicity, a checkout system 100 including one product registration device 10 and one settlement device 20 will be described.

Figure 2 is a block diagram showing the configuration of the product registration device 10. As shown in the figure, the product registration device 10 has a configuration in which a CPU (Central Processing Unit) 101, a ROM (Read Only Memory) 102, a RAM (Random Access Memory) 103, a scanner unit (product identification information registration means) 104, a store clerk display unit 105, a customer display unit 106, a hard disk (product data storage means) 107, a store clerk operation unit 108, a communication unit 109, a buzzer 110, and a printing unit (media recording means) 111 are connected via a bus 112.

The CPU 101 is a control unit that controls the entire product registration device 10 by reading out the product registration program stored in the ROM 102, expanding it into the RAM 103, and executing the steps of the expanded product registration program. By executing the product registration program, the CPU 101 generates a two-dimensional code based on the product identification information of the product purchased by shopper C and, if shopper C has a gift certificate that he or she wishes to use for payment, the gift certificate information. This two-dimensional code is, for example, a QR code (registered trademark).

As described above, ROM 102 stores the product registration program to be executed by CPU 101, and also stores product registration device identification information, which is identification information for product registration device 10. RAM 103 expands the product registration program read from ROM 102 by CPU 101, and stores various variables and data generated by CPU 101 executing the product registration program, such as product identification information and gift certificate information.

The scanner unit 104 is a barcode reader that reads a barcode and extracts the information recorded in the barcode. When the operator S himself/herself moves a barcode that has been attached, pasted, printed, etc. to an item purchased by shopper C to be positioned so that it can be read in the barcode reading area of the scanner unit 104, the scanner unit 104 reads the barcode, extracts the item identification information recorded in the barcode, and stores it in RAM 103.

The store clerk display unit 105 is a display unit that presents information to the operator S, and is, for example, a liquid crystal display device. Every time the scanner unit 104 reads the barcode of a product and stores the product identification information recorded in the barcode in the RAM 103, the CPU 101 extracts the product name and sales price of the product from the data table based on the product identification information and the data table of the product data file stored in the hard disk 107, and supplies the product name and sales price to the store clerk display unit 105, which then displays the product name and sales price.
The clerk display unit 105 also receives from the CPU 101 and displays gift certificate information generated by the CPU 101 based on an operation signal supplied from the clerk operation unit 108 to the CPU 101 in accordance with the operation of the clerk operation unit 108 by the operator S.

The customer display unit 106 is a display unit that presents information to shopper C, and is, for example, a liquid crystal display device. For example, the customer display unit 106 receives information from the CPU 101 and displays the same information as the store clerk display unit 105. The hard disk 107 is a magnetic hard disk device that records product data files supplied from a store controller connected via the communication unit 109. Note that the hard disk 107 may record a product registration program instead of the ROM 102.

The store clerk operation unit 108 includes a plurality of voucher keys for inputting the type of voucher, number keys for inputting the number representing the amount of the voucher, and a current total key for inputting the completion of the registration of the purchased items and the voucher. Note that the key is not limited to the current total key, and any key that indicates the completion of the registration of the purchased items and the voucher information may be used, and may also be a print key that indicates the start of printing, for example. In other words, the store clerk operation unit 108 includes a payment information registration means.
The store clerk operation unit 108 may also be provided with a pre-registered product designation key for inputting product identification information of a specific product. In this way, the product registration device 10 registers the product identification information of a specific product by pressing the product designation key corresponding to the specific product, rather than by reading a barcode.

The communication unit 109 is a communication interface that communicates with external devices, and is, for example, a network interface unit that is connected to a store controller via a LAN. The buzzer 110 is a sound generating unit that generates confirmation sounds and warning sounds, and generates a digitally synthesized sound, for example, when the scanner unit 104 successfully reads a barcode, when each key on the clerk operation unit 108 is pressed, or when an incorrect operation is performed by the operator S. The printing unit 111 prints the two-dimensional code generated by the CPU 101 on a paper medium and outputs it as a transaction receipt.

Figure 3 is a block diagram showing the configuration of the settlement device 20. As shown in the figure, the settlement device 20 has a configuration in which a CPU 201, a ROM 202, a RAM 203, a scanner unit (medium reading means) 204, a display unit 205, a customer operation unit 206, a communication unit 207, a buzzer 208, a printing unit 209, and a change dispenser 210 are connected via a bus 211.

The CPU 201 is a control unit that controls the entire settlement device 20 by reading out the accounting program stored in the ROM 202, expanding it into the RAM 203, and executing the steps of the expanded accounting program. By executing the accounting program, the CPU 201 performs settlement processing based on the two-dimensional code recorded information obtained from the two-dimensional code printed on the accounting receipt.

Specifically, the CPU 201 extracts the product names and sales prices of the products purchased by the shopper C from the data table based on the product identification information read from the two-dimensional code by the scanner unit 204 and stored in the RAM 203, and a data table of product data files previously stored in the RAM 203, and calculates the total purchase amount of the extracted sales prices. In other words, the CPU 201 includes a total purchase amount calculation means.
Furthermore, the CPU 201 calculates the total amount of the gift certificates based on the gift certificate information read from the two-dimensional code by the scanner unit 204 and stored in the RAM 203. If the information read from the two-dimensional code does not include gift certificate information, the CPU 201 sets the total amount of the gift certificates to 0 yen.

The CPU 201 also calculates the payment request amount or refund amount based on the calculated total purchase amount and total gift certificate amount. Specifically, for example, the CPU 201 calculates the difference between the total purchase amount and the total gift certificate amount (total purchase amount - total gift certificate amount), and if the difference is 0 or a positive integer, the difference is the payment request amount, and if the difference is a negative integer, the difference is the refund amount. In other words, the CPU 201 includes a settlement amount calculation means.

As described above, ROM 202 stores the accounting program to be executed by CPU 201, and also stores settlement device identification information, which is identification information for settlement device 20. RAM 203 stores product data files supplied from a store controller connected via communication unit 207. RAM 203 also expands the accounting program read from ROM 202 by CPU 201, and stores various variables and data generated by CPU 201 executing the settlement recording program, such as the total purchase amount, total gift certificate amount, and payment request amount or refund amount.

The scanner unit 204 is a two-dimensional code reader that reads a two-dimensional code and extracts the two-dimensional code information recorded in the two-dimensional code. When shopper C's own actions position the two-dimensional code printed on the accounting receipt so that it can be read in the two-dimensional code reading area of the scanner unit 204, the scanner unit 204 reads the two-dimensional code and extracts the product identification information, or the product identification information and gift certificate information, recorded in the two-dimensional code, and stores it in RAM 203.

The display unit 205 is a display unit that presents information to shopper C, and is, for example, a liquid crystal display device. The display unit 205 receives from the CPU 201 an accounting menu that includes information such as the product names of the products purchased by shopper C, the total purchase amount, the total gift certificate amount, the requested payment amount or refund amount, and a character string that prompts shopper C to perform a settlement operation, and displays the accounting menu. The display unit 205 also displays the settlement amount information provided by the CPU 201. The settlement amount is the post-settlement amount that the change dispenser 210 notifies the CPU 201 after processing the change.

The customer operation unit 206 is provided in conjunction with the display unit 205 and is a touch panel input device that generates operation signals by operating GUI (Graphical User Interface) operation buttons displayed on the display unit 205 under the control of the CPU 201. The customer operation unit 206 is equipped with an accounting key that causes the CPU 201 to start the settlement process, and a settlement key that causes the change dispenser 210 to start the change process. In other words, the display unit 205 and the customer operation unit 206 form a touch panel type liquid crystal display.

The communication unit 207 is a communication interface that communicates with external devices, and is, for example, a network interface unit that is connected to the store controller via a LAN. The buzzer 208 is a sound generating unit that generates confirmation sounds and warning sounds, and generates a digitally synthesized sound, for example, when the scanner unit 204 successfully reads a two-dimensional code, when each key on the customer operation unit 206 is pressed, when shopper C performs an incorrect operation, etc.

The printing unit 209 prints and outputs a receipt on paper when the CPU 201 has completed the settlement process. The change machine 210 is an automatic change machine equipped with an input and output port for coins and bills. The change machine 210 counts the coins and/or bills inserted into the input port by shopper C and notifies the CPU 201 of the amount deposited. The change machine 210 also dispenses the amount of money to be refunded based on the amount notified by the CPU 201 and discharges it to the output port.

Next, the product data file will be described. FIG. 4 is a diagram showing the data structure of the product data file. As shown in the figure, the product data file is a file of a data table (product data) including records having the items of "product identification information", "product name", and "sales price". The item "product identification information" includes information recorded in a barcode that is attached, pasted, printed, etc. to a product. In this embodiment, as described above, the product identification information is a 13-digit JAN code. Therefore, the two most significant digits of the product identification information are information that identifies a country code, in-store marking, or the like. The item "product name" includes a character string that represents the product name of the product. The item "sales price" includes a number that represents the sales price of the product. The primary key in this data table is the item "product identification information".

Next, the coupon information will be described. Fig. 5 is a diagram showing the internal data structure of the coupon information. As shown in the figure, the coupon information is, for example, a 13-digit number, with the most significant two digits representing the "identifier", the next two digits representing the "type", the next two digits representing the "spare", and the remaining seven digits representing the "amount".
The "identifier" is a fixed number commonly applied to the gift certificate information, and is a number that does not match the two most significant digits of the product identification information. For example, if the product identification information is a JAN code, the "identifier" is a number (e.g., "90") that is not included in the country code or in-store marking. The "type" is a number that indicates the type of gift certificate, for example, gift certificates and gift certificates = "01", coupons = "02", and service certificates = "03". The "reserve" is a number that is not used (referenced) by the product registration device 10 and the settlement device 20, and is "00". The "reserve" may also be used to expand the number of the "type" to classify the gift certificates in more detail. The "amount" is a number that indicates the amount written on the gift certificate, or the amount related to the product name or service content written on it. For example, for a gift certificate that reads "XX common gift certificate ￥1,000," the "amount" is "0001000," and for a coupon that reads "△△ store coupon ￥500 off," the "amount" is "0000500."

When the CPU 101 of the product registration device 10 executes the product registration program and registers the product purchased by shopper C and the voucher information of the voucher, the product identification information and the voucher information are stored in the RAM 103. FIG. 6 is a diagram showing a memory map of the product identification information and the voucher information stored in the RAM 103. Referring to FIG. 6 and FIG. 4 together, the memory map shown in FIG. 6 shows that a product with the product name "XX oil" and a sales price of "650", a product with the product name "△△ meat" and a sales price of "850", and a voucher with the type "gift certificate and gift certificate" and the amount of "1000" are registered.

Next, the accounting receipt will be described. Figure 7 is an example of an accounting receipt printed by the printing unit 111 of the product registration device 10. As shown in the figure, the accounting receipt 7 is printed with the printing date and time ("Printed date: May 6, 2010, 14:30:50"), a transaction identification number that identifies the transaction by shopper C ("Shopping basket No. 126"), the number of items purchased ("Number of items purchased: 2"), and a QR code (registered trademark), which is a two-dimensional code.

When voucher information is also registered in the product registration process, the product registration device 10 may print voucher usage information (particularly the voucher amount) for the voucher on the accounting receipt. In other words, the product registration device 10 stores fixed phrases for voucher usage information for each "type" of voucher information in the RAM 103, and prints fixed phrases with amount information added on the accounting receipt 7 based on the "type" and "amount" of the voucher information by the printing unit 111. Specifically, for voucher information with a "type" of "01" and an "amount" of "0005000", the product registration device 10 prints voucher usage information such as "The deposited gift voucher worth ￥5,000 will be used for settlement" on the accounting receipt 7.

Next, the operation of the checkout system 100 will be described separately for the product registration process executed by the product registration device 10 and the settlement process executed by the settlement device 20.
First, a description will be given of the product registration process by the product registration device 10. Fig. 8 is a flowchart showing the procedure of the product registration process executed by the product registration device 10. When the CPU 101 reads out the product registration program stored in the ROM 102, loads it into the RAM 103, and starts execution of the loaded product registration program, the product registration device 10 starts the product registration process according to the flowchart in the figure.

In step S1, when the barcode attached, pasted, printed, etc. to the purchased item of the shopper C is positioned so that it can be read in the barcode reading area of the scanner unit 104 by the operator S's own action, the scanner unit 104 reads the barcode, extracts the product identification information recorded in the barcode, and stores the product identification information in RAM 103. If there are multiple identical purchased items, when the operator S inputs the number of purchased items by operating the numeric keys of the store clerk operation unit 108, the store clerk operation unit 108 supplies a key code representing the purchase number to the CPU 101, and the CPU 101 stores the same number of product identification information as the purchased item in RAM 103 based on the supplied key code.

Next, in step S2, the CPU 101 determines whether any of the multiple gift certificate keys on the clerk operation unit 108 has been pressed. In other words, when a gift certificate is presented by a shopper C who wishes to use the gift certificate to settle the bill, the operator S receives the gift certificate from the shopper C, determines the type of the gift certificate, and presses the gift certificate key corresponding to the determined type from among the multiple gift certificate keys provided corresponding to the type of gift certificate. For example, when the operator S receives a gift certificate from the shopper C that reads "XX common gift certificate ￥1,000", he presses the gift certificate key provided corresponding to the gift certificate and gift certificate. This operation causes the clerk operation unit 108 to supply the CPU 101 with the key code of the pressed gift certificate key, and the CPU 101 takes in the supplied key code and determines that the gift certificate key provided corresponding to the gift certificate and gift certificate has been pressed. If the CPU 101 determines that the coupon key has been pressed (S2: YES), the process proceeds to step S3; if the CPU 101 determines that the coupon key has not been pressed (S2: NO), the process proceeds to step S4.

In the processing of step S3, the CPU 101 generates gift certificate information based on a predetermined gift certificate identifier (e.g., "90"), a predetermined type number corresponding to the pressed gift certificate key (e.g., "01" for gift certificates and gift vouchers), and a numeric code of the amount supplied from the store clerk operation unit 108 (e.g., "1000"), and stores this gift certificate information in the RAM 103.

Specifically, if the gift certificate is a 1,000 yen gift certificate or gift voucher, the CPU 101 generates the gift certificate information "9001000001000" shown in Figure 5 based on, for example, the predetermined gift certificate identifier "90", the type number "01" predetermined in accordance with the gift certificate key associated with the pressed gift certificate or gift voucher, and the numeric code for the amount "1000" supplied from the store clerk operation unit 108, and stores it in RAM 103.
In addition, if the gift certificate is a coupon for a 500 yen discount, the CPU 101 generates the gift certificate information "9002000000500" shown in Figure 5 based on, for example, the predetermined gift certificate identifier "90", the type number "02" predetermined in accordance with the gift certificate key associated with the pressed coupon, and the numeric code of the amount "500" supplied from the store clerk operation unit 108, and stores it in RAM 103.

Next, in step S4, the CPU 101 determines whether the current total key on the clerk operation unit 108 has been pressed. That is, the operator S presses the current total key on the clerk operation unit 108 when he has completed the product registration of the purchased items of the shopper C, and has confirmed that the registration of the gift certificate to be used (if there is one) has been completed, or when the shopper C has not requested to use the gift certificate. This operation causes the clerk operation unit 108 to supply the key code of the pressed current total key to the CPU 101, and the CPU 101 reads the supplied key code and determines that the current total key has been pressed. If 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 item information and gift certificate information stored in the RAM 103, and proceeds to step S5. On the other hand, if 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 supplies the printing unit 111 with the date and time information of the clock, a transaction identification number represented by a number that increases by one for each transaction, the number of products purchased, which is the number of product identification information pieces, and the two-dimensional code. The printing unit 111 then prints out 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 the procedure of the settlement process executed by the settlement device 20. When the CPU 201 reads out the settlement program stored in the ROM 203, loads it into the RAM 203, and starts execution of the loaded settlement program, the settlement device 20 starts the settlement process according to the flowchart in the figure.
In addition, before executing the settlement process, the settlement device 20 stores the product data file provided by the store controller in the RAM 203 in advance.

In step S11, when shopper C's own action positions the two-dimensional code printed on the accounting receipt so that it can be read in the two-dimensional code reading area of scanner unit 204, scanner unit 204 reads the two-dimensional code, extracts the two-dimensional code recording information recorded in the two-dimensional code, and stores it in RAM 203.
Specifically, for example, the scanner unit 204 reads the two-dimensional code printed on the accounting receipt, extracts the product identification information "4912345678966" and "4912345678980" recorded in the two-dimensional code, and the coupon information "9001000001000", and stores them in the RAM 203. As a result, the memory map shown in FIG.

Next, CPU 201 extracts product identification information from the two-dimensional code recording information stored in RAM 203, and uses the extracted product identification information as a search key to extract product names and sales prices from a data table of a product data file previously stored in RAM 203. As a method for extracting product identification information, for example, CPU 201 extracts only data whose upper two digits indicate product identification information from the two-dimensional code recording information stored in RAM 203. Next, CPU 201 counts the number of extracted product identification information that are the same (however, if there are no identical numbers, the counting result is "1"), and stores the counting result (i.e., the number of purchases), product name, and sales price for each product identification information in RAM 203. CPU 201 then calculates the total amount of the sales prices, and stores this in RAM 203 as the total purchase amount.

Next, in step S12, the CPU 201 searches for gift certificate information from the two-dimensional code recording information stored in the RAM 203, and if gift certificate information is detected (S12: YES), it extracts the amount from the gift certificate information. As a method for extracting gift certificate information, for example, the CPU 201 extracts only data whose upper two digits indicate 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 amounts of one or more gift certificate information, stores this in the RAM 203 as the total gift certificate amount, and proceeds to the processing of step S13.
On the other hand, if the CPU 201 does not extract gift certificate information from the two-dimensional code recorded information stored in the RAM 203 (S12: NO), it stores the gift certificate total amount as "0" in the RAM 203 and proceeds to the process of 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 if the difference is "0" or a positive integer (S13: YES), the CPU 201 stores the difference in the RAM 203 as the payment request amount and proceeds to step S14. On the other hand, if the calculated difference is a negative integer (S13: NO), the CPU 201 stores the difference in the RAM 203 as the refund amount and proceeds to step S22.

In step S14, the CPU 201 supplies the display unit 205 with accounting menu (a) including information stored in the RAM 203 regarding the product names, purchase quantities, total purchase amounts, total gift certificate amounts, and requested payment amounts of the products purchased by shopper C. The accounting menu (a) also includes an image of the accounting key GUI operation button. The display unit 205 then displays the accounting menu (a). The accounting key, which is a GUI operation button, has the function of the customer operation unit 206.
An example of the accounting menu (a) displayed by the display unit 205 is shown in Fig. 10. As shown in the figure, in the processing of step S14, the display unit 205 displays menu 50a. On the left side of the menu 50a, the names and purchase quantities of the products purchased by shopper C are displayed for each product, and on the right side of the menu 50a, information is displayed including the total purchase amount, the total gift certificate amount, the requested payment amount, the accounting key 51, and information encouraging the user to press the accounting key 51 ("Please press the accounting key").

In step S15, when the billing key 51 is touched by shopper C, the customer operation unit 206 supplies an operation signal indicating that the billing key 51 has been touched to the CPU 201, and the CPU 201 receives the operation signal and proceeds to processing in step S16.
Next, in step S16, the CPU 201 supplies a menu including the requested payment amount stored in the RAM 203 and an image of the GUI operation button of the settlement key to the display unit 205. The display unit 205 then displays the menu. The settlement key, which is a GUI operation button, has the function of the customer operation unit 206.
An example of the menu displayed by the display unit 205 is shown in Fig. 11. As shown in Fig. 11, in the process of step S16, the display unit 205 displays a menu 60a. The menu 60a displays information including the payment amount requested of the shopper C, a settlement key 61, and information prompting the shopper C to press the settlement key 61 ("Please insert into the change machine and press the settlement key").

Next, in step S17, when the customer C inserts money corresponding to the requested payment amount into the insertion slot of the change machine 210, the change machine 210 deposits the inserted money and notifies the CPU 201 of the deposited amount. The CPU 201 then stores the deposited amount in the RAM 203.
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, if the deposit amount is "1000", the display unit 205 displays the menu 60b shown in FIG.
Next, in step S19, when the settlement key 61 is touched by shopper C, the customer operation unit 206 supplies an operation signal indicating that the settlement key 61 has been touched to the CPU 201, and the CPU 201 receives the operation signal and proceeds to processing of step S20.

In step S20, which is executed following the process of step S19, the CPU 201 calculates the difference between the payment request amount stored in the RAM 203 and the deposit amount (deposit amount - payment request amount), and if the difference is "0" or a positive integer (i.e., the change amount is 0 yen or there is change), stores the difference in the RAM 203 as the change amount. Next, the CPU 201 notifies the change machine 210 of the change amount. Having received the change amount notification, the change machine 210 dispenses the change amount and discharges it to the discharge port. The change machine 210 then supplies a notification of the completion of the change process to the CPU 201. 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, if the change amount is "500", the display unit 205 displays the menu 70a shown in FIG. 13.

Note that in the processing of step S20 above, if the difference calculated by the CPU 201 is a negative integer (i.e., if there is a shortfall), the difference is stored in the RAM 203 as a new payment request amount (not shown in the flowchart of FIG. 9), and the processing returns to step S16.

In step S21, when the CPU 201 receives a notification from the change dispenser 210 that change processing is complete, it supplies receipt information stored in RAM 203 to the printing unit 209, the information including the product name, sales price, number of purchases, total purchase amount, total gift certificate amount, deposit amount, and change amount of the products purchased by shopper C. The printing unit 209 then prints the receipt information on paper media, outputs it as a receipt, and notifies the CPU 201 of printing completion information. The CPU 201, having received the printing completion information, ends the processing of the flowchart shown in FIG. 9.

If the difference calculated by CPU 201 in the processing of step S13 is a negative integer (S13: NO), in step S22, CPU 201 supplies accounting menu (b) including information on the product names, purchase quantities, total purchase amount, total gift certificate amount, and refund amount of the products purchased by shopper C stored in RAM 203, as well as images of GUI operation buttons for the accounting keys, to display unit 205. Display unit 205 then displays that accounting menu (b).
An example of the accounting menu (b) displayed by the display unit 205 is shown in Fig. 14. As shown in the figure, in the processing of step S22, the display unit 205 displays menu 50b. On the left side of menu 50b, the names and purchase quantities of the products purchased by shopper C are displayed for each product, and on the right side of menu 50b, information is displayed including the total purchase amount, the total gift certificate amount, the refund amount, the accounting key 51, and information encouraging the user to press the accounting key 51 ("Please press the accounting key").

In step S23, when the billing key 51 is touched by shopper C, the customer operation unit 206 supplies an operation signal indicating that the billing key 51 has been touched to the CPU 201, and the CPU 201 receives the operation signal and proceeds to the processing of step S20.

In step S20, which is executed following the processing of step S23, the CPU 201 notifies the change machine 210 of the refund amount stored in the RAM 203. Having received the notification of the refund amount, the change machine 210 dispenses the refund amount of money and discharges it to the discharge port. The change machine 210 then supplies a notification of the completion of the change process to the CPU 201. Next, the CPU 201 supplies the refund amount stored in the RAM 203 to the display unit 205 as the change amount, and the display unit displays the change amount.

If the CPU 201 does not extract gift certificate information from the two-dimensional code recorded information stored in RAM 203 in the process of step S12 (S12: NO), in step S24 the CPU 201 supplies to the display unit 205 an accounting menu (c) including the information stored in RAM 203 on the product names, purchase quantities, and total purchase amount of the products purchased by shopper C, as well as images of GUI operation buttons for the accounting keys. The display unit 205 then displays the accounting menu (c). Then the process proceeds to step S15.
An example of the accounting menu (c) displayed by the display unit 205 is shown in Figure 15. As shown in the figure, in the processing of step S24, the display unit 205 displays menu 50c. On the left side of menu 50c, the product names and purchase quantities of the products purchased by shopper C are displayed for each product, and on the right side of menu 50c, information including the total purchase amount, accounting key 51, and information encouraging the user to press accounting key 51 ("Please press the accounting key").

As described above, according to the first embodiment, the operator S only registers the product identification information recorded in the barcode attached, pasted, printed, etc., to the purchased product and the coupon information used by the shopper C when registering the product purchased by the shopper C using the product registration device 10. The shopper C then settles the payment at the settlement device 20 using an accounting receipt on which the product identification information and the coupon information are two-dimensionally coded and printed. Thus, the shopper C who has completed registration using the product registration device 10 moves to a desired settlement device 20 (e.g., an available settlement device 20) to settle the payment, so that the time spent at the product registration device 10 can be shortened, and the checkout system 100 can shorten the transaction time without the risk of a bottleneck (long waiting time by the shopper) occurring in the transaction processing by the operator S. In addition, since the operator S receives the coupon from the shopper C and registers the coupon information at the product registration device 10, there is no risk of the shopper C misusing the coupon, such as reusing the coupon. In addition, the checkout process is efficient because the customer C does not need to call or have an operator S present when making a payment using a gift certificate. In addition, because the customer C does not have to wait long, there is no need to increase the number of lanes for the product registration device 10, and an increase in labor costs can be suppressed.
That is, according to the first embodiment, when payment is made using gift certificate information, fraudulent use of gift certificates can be reliably prevented and check-out can be performed quickly and efficiently without increasing labor costs.

Furthermore, according to the first embodiment, by making the code printed on the accounting receipt output by the product registration device 10 a two-dimensional code, a large amount of information can be included in the two-dimensional code, so that the number of times it needs to be read by the settlement device 20 can be reduced to one, thereby preventing accounting errors and enabling efficient accounting.
Furthermore, according to the first embodiment, the gift certificate information registered in the product registration device 10 is displayed on the display unit 205 of the settlement device 20 at the time of settlement, so that shopper C can visually confirm that the gift certificate he or she presented will indeed be used in the settlement, and can quickly complete the transaction without having to worry about having to double-check with the store clerk.
Furthermore, in the first embodiment, if the product registration device 10 is configured to print voucher usage information (especially the amount of the voucher) on the accounting receipt, shopper C can confirm before the settlement process that the desired amount for the gift certificate etc. that he or she has presented will indeed be used in the settlement, and therefore the settlement can be carried out quickly without having to worry about double-checking with the store clerk.

[Second embodiment]
In the checkout system 100 in the first embodiment described above, the product registration device 10 converts product identification information and product coupon information into a two-dimensional code and prints and outputs the code on a accounting receipt, and the settlement device 20 reads the two-dimensional code printed on the accounting receipt and performs settlement processing based on the two-dimensional code recording information recorded in the two-dimensional code and the data table of the product data file supplied from the store controller.
The second embodiment of the present invention is an example in which the two-dimensional code recorded information included in the two-dimensional code recorded on the accounting receipt is different from that in the first embodiment.

16 is a block diagram showing the overall configuration of a checkout system according to a second embodiment of the present invention. As shown in the figure, a checkout system 200 has two product registration devices 10a, two payment devices (automatic payment devices) 20a, and a store controller 30, which are connected via a LAN 40. The configurations of the product registration device 10a and the payment device 20a are the same as those of the product registration device 10 and the payment device 20 in the first embodiment, and therefore a description of the specific configurations of each will be omitted.
The number of product registration devices 10a and the number of payment settlement devices 20a included in the checkout system 200 are not limited to two each, and are determined according to, for example, the size and costs of the store.

The operation of the checkout system 200 will now be described. Fig. 17 is a sequence diagram showing the processing procedure between the product registration device 10a, the settlement device 20a, and the store controller 30. First, in step S31, the CPU 101 of the product registration device 10a executes a product registration process similar to the product registration process in the first embodiment, and stores product identification information and gift certificate information in the RAM 103.
Next, in step S32, the CPU 101 generates a transaction identification number that identifies the transaction by the shopper C, generates a registration data file including the transaction identification information, the product identification information stored in the RAM 103, and the gift certificate information, and stores the file data in the RAM 103. The transaction identification information is, for example, a positive integer that increases with each transaction.
Next, the CPU 101 converts the transaction identification information into a two-dimensional code and supplies it to the printing unit 111. The printing unit 111 then prints the two-dimensional code on a paper medium and outputs it as a transaction receipt.

Next, in step S33, the CPU 101 reads out the file data of the registration data file stored in the RAM 103 and supplies it from the communication unit 109 via the LAN 40 to the store controller 30.
In step S34, the store controller 30 imports the registration data file supplied from the product registration device 10a, and then in step S35, the store controller 30 stores the imported registration data file in a storage unit such as a magnetic hard disk drive.
Next, in step S36, the store controller 30 distributes the registration data file to all settlement devices 20a included in the checkout system 200 via the LAN 40.

In step S37, all settlement devices 20a included in the checkout system 200 receive the registration data file via the communication unit 207 and store it in the RAM 203.
Next, in step S38, the settlement device 20a, which has had the scanner unit 204 read the two-dimensional code using the accounting receipt printed in the process of step S32, extracts transaction identification information from the two-dimensional code recorded information recorded in the two-dimensional code and stores it in RAM 203. The CPU 201 of the settlement device 20a then uses the transaction identification information stored in RAM 203 and the file data of the registered data file as a search key to identify the registered data file, and extracts product identification information and gift certificate information from the registered data file. Next, the CPU 201 executes the settlement process in the same manner as in the first embodiment, based on the extracted product identification information and gift certificate information.

As described above, according to the second embodiment, the operator S only registers the product identification information recorded in the barcode attached, pasted, printed, etc., to the purchased product and the gift certificate information used by the shopper C when registering the purchased product by the product registration device 10a. The shopper C then settles the payment at the settlement device 20a using the accounting receipt on which the transaction identification information is printed as a two-dimensional code. Thus, the shopper C who has completed the registration by the product registration device 10a moves to the desired settlement device 20a (for example, an available settlement device 20a) to settle the payment, so that the time spent at the product registration device 10a can be shortened. Thus, the checkout system 200 can shorten the transaction time without the risk of a bottleneck (long waiting time by the shopper) occurring in the transaction processing by the operator S. In addition, since the operator S receives the gift certificate from the shopper C and registers the gift certificate information, there is no risk of the shopper C misusing the gift certificate, such as reusing the gift certificate. In addition, the checkout process is efficient because the customer C does not need to call or have an operator S present when making a payment using a gift certificate. In addition, because the customer C does not have to wait long, there is no need to increase the number of lanes for the product registration device 10a, and an increase in labor costs can be suppressed.
That is, according to the second embodiment, when payment is made using gift certificate information, fraudulent use of gift certificates can be reliably prevented and check-out can be performed quickly and efficiently without increasing labor costs.

In the above-mentioned first embodiment, an example was described in which the accounting receipt was a paper medium on which a two-dimensional code was printed. Alternatively, an IC card with a built-in IC chip capable of writing and reading data may be used in place of the accounting receipt, with the product registration device 10 writing the product identification information and gift certificate information to the IC card, and the settlement device 20 reading the product identification information and gift certificate information from the IC card for use.
Similarly, the merchandise registration device 10a may write the transaction identification information to an IC card, and the settlement device 20 may read the transaction identification information from the IC card and use it.
When an IC card is used, a collection box for the IC card used in the settlement process is provided next to the settlement device 20.

In the first embodiment, the product registration device 10 and the settlement device 20 are not connected online, and the product identification information and the coupon information are recorded in the two-dimensional code printed on the accounting receipt 7. Alternatively, for example, all the product registration devices 10 and all the settlement devices 20 in the checkout system 100 may be connected by a LAN, and the product registration device 10 may distribute table information that associates the transaction identification number, the product identification information, and the coupon information to all the settlement devices 20 for each transaction. In this case, the printing unit 111 of the product registration device 10 converts the transaction identification number of the transaction into a two-dimensional code or a barcode for each transaction and prints it on the accounting receipt. The scanner unit 204 of the settlement device 20 then reads the code printed on the accounting receipt to obtain the transaction identification number, and the settlement device 20 uses the obtained transaction identification number as a search key to obtain the product identification information and the coupon information from the table information provided by the product registration device 10, and performs the settlement process.

Furthermore, the scanner unit 104 of the product registration device 10 may directly convert the product identification information and payment information into two-dimensional codes and record them as shown in the first embodiment, or may code and record key information that can indirectly identify the product identification information and payment information. In the case of indirectly identifying them in this way, for example, the product registration device 10 transmits the registered product identification information and payment information to the settlement device 20 in association with key information, and the settlement device 20 identifies the product identification information and payment information transmitted from the product registration device 10 by having the scanner unit 204 read the key information recorded on a medium.
Also, for example, the product registration device 10 may associate the registered product identification information and payment information with key information and store them in RAM 103, and the settlement device 20 may read the key information recorded on a medium using the scanner unit 204, and refer to the product identification information and payment information stored in RAM 103 of the product registration device 10 based on the key information.

In the first and second embodiments, an example is shown in which the gift certificate information is input by operating the numeric keys on the clerk operation unit 108 of the product registration device 10, 10a. Alternatively, for example, the amount and information regarding the product eligible for the service may be printed as a barcode on the gift certificate, and the scanner unit 104 may read the barcode on the gift certificate to register the gift certificate information.

In the first and second embodiments, the settlement device 20, 20a calculates the total purchase amount, but the product registration device 10, 10a may calculate the total purchase amount and convert the total purchase amount into a two-dimensional code together with the product identification information and gift certificate information. In this case, the settlement device 20, 20a can obtain the product identification information, gift certificate information, and the total purchase amount from the two-dimensional code printed on the accounting receipt and perform the settlement process.

In the first and second embodiments, the settlement device 20, 20a is an example equipped with a change dispenser 210 and performs cash settlement. In addition, the settlement device 20, 20a may be a device that performs settlement by electronic money payment (automatic settlement device). Furthermore, the settlement device 20, 20a may allow the shopper C to select the settlement method between cash settlement and settlement by electronic money payment.

In the second embodiment, when the settlement device 20a reads the identification information from the medium and settles the payment, the CPU 101 may refer to the store controller 30 for the product identification information and payment information specified by the read identification information. When the settlement device 20a reads the identification information from the medium, the settlement device 20a may transmit a command to the store controller 30 requesting that the product identification information and payment information corresponding to the identification information be transmitted to the settlement device 20a. The settlement device a may then import the product identification information and payment information transmitted from the store controller 30 based on the command and perform settlement processing.

The above describes an embodiment of the present invention in detail with reference to the drawings, but the specific configuration is not limited to this embodiment, and includes designs that do not deviate from the gist of the present invention.
