Description

Embodiments of the present invention relate to a sales data processing device and a program.

Traditionally, when a business that operates an export goods sales floor (duty-free shop) sells products to non-residents such as foreign tourists, it has been necessary to pay taxes such as consumption tax on the sales target. There is a so-called tax exemption system. The tax exemption system is applied when the total sales amount of goods in the tax exemption category is equal to or higher than the specified amount.

The above-mentioned total sales amount does not have to be the amount related to a single payment, but may be the total amount of multiple payments as long as they are made on the same day at the same store. When tax exemption is applied based on the total amount of multiple payments, procedures must be carried out for transactions that have already been accounted for, but sales data processing devices that have the functionality for this procedure already exist. The function of this existing device is to improve the complexity of canceling a transaction that has already been accounted for and then starting a new transaction that applies tax exemption, and applies tax exemption to the transaction that has already been accounted for.

However, in the existing device described above, if the total amount of amounts related to multiple payments does not reach a predetermined amount, the process is terminated with a notification that tax exemption cannot be applied. If the customer (non-resident) makes additional purchases beyond the insufficient amount and the total amount reaches the amount for which tax exemption is applied, the customer and the operator must start the procedure such as reading the receipt all over again. .

The problem to be solved by the present invention is to eliminate waste due to duplication of work when there is an additional purchase to compensate for the shortage of applicable amount in the tax exemption application procedure for settled transactions.

The sales data processing device of the embodiment includes a first acquisition means for acquiring a transaction number, and a product code corresponding to the transaction number based on the transaction number acquired by the first acquisition means, and a product code corresponding to the transaction number and the product. a second acquisition means for acquiring the product code from a storage unit that stores the product code in association with the product code; a third acquisition means for acquiring the total price excluding tax corresponding to the product code acquired by the second acquisition means; a determination means for determining whether the total amount excluding tax acquired by the third acquisition means satisfies the conditions for tax exemption; and if it is determined by the determination means that the total amount excluding tax does not satisfy the conditions for tax exemption, an insufficient amount corresponding to the tax exemption classification is provided. Display means for displaying a plurality of buttons , one of which is an add button , which accepts operations along with the amount , and when the add button is operated, accepts an additional purchase of a tax exempt product and displays the price of the product. additional means for adding up the total amount .

In the embodiment, tax exemption processing (post-payment tax exemption application processing) performed on a transaction in which a product is sold to a customer including tax (tax-inclusive sales transaction) will be explained using a POS (Point Of Sales) system used in a duty free shop as an example. . A duty-free shop is an export goods sales place that sells goods (products) used in daily life to non-residents such as foreign tourists in a certain manner. Further, the post-settlement tax exemption application process is performed based on history information of past transactions (ie, settled transactions).

FIG. 1 is a schematic configuration diagram of a POS system 1 according to an embodiment. The POS system 1 includes a plurality of (two in the figure) POS terminals 2, a network 3, and a server 4. The POS terminal 2 is an example of a sales data processing device, and is installed in a duty-free shop. The network 3 is a LAN (Local Area Network) or the like, and connects the POS terminal 2 and the server 4. The server 4 centrally manages the plurality of POS terminals 2 via the network 3.

The server 4 is in charge of controlling the entire POS system 1. FIG. 2 is a block diagram showing the hardware configuration of the server 4. As shown in FIG. The server 4 is, for example, an information processing device with a general computer configuration, and includes a control unit 400 that includes a CPU (Central Processing Unit) 41, a ROM (Read Only Memory) 42, a RAM (Random Access Memory) 43, etc. We are prepared.

The server 4 also includes a controller 44, a keyboard 45, a display section 46, a printer 47, an HDD (Hard Disk Drive) 48, a bus 49, and a communication I/F (interface) 50.

The bus 49 connects the control unit 400 and each of the above units (controller 44, HDD 48, and communication I/F 50). Communication I/F 50 connects server 4 to network 3. Through this connection, the control unit 400 and the plurality of POS terminals 2 can communicate online with each other.

Keyboard 45, display section 46, and printer 47 are connected to control section 400 via controller 44 and bus 49. The keyboard 45 accepts operations by the server administrator. The display unit 46 displays information for server administrators in the form of images. The printer 47 outputs printed matter.

The HDD 48 stores various control programs 481 that operate the control unit 400. The HDD 48 also stores a product master file F1, a tax exemption category file F2, and a tax exemption setting value file F3.

Furthermore, the HDD 48 holds a transaction history DB1. The transaction history DB 1 is a database for accumulating history information of the above-mentioned settled transactions, that is, information regarding transactions for which sales registration processing was performed at the POS terminal 2. The HDD 48 holds a reservation history DB2. The suspension history DB2 holds data for processing when the above-described post-settlement tax exemption application processing is suspended midway. The post-settlement tax exemption application process is a process that applies tax exemption to tax-included sales transactions among settled transactions.

Note that the control program 481 executed by the server 4 of the embodiment is a file in an installable or executable format, and may be configured to be recorded and provided on a computer-readable recording medium. . Such recording media include CD-ROM, flexible disk (FD), CD-R, and DVD (Digital Versatile Disk).

Furthermore, the control program 481 executed by the server 4 of the embodiment may be stored on a computer connected to a network such as the Internet, and may be provided by being downloaded via the network. Furthermore, the control program 481 executed by the server 4 of the embodiment may be configured to be provided or distributed via a network such as the Internet.

Next, the product master file F1 and the product classification (classification) set in the product master file F1 will be explained. FIG. 3 is a diagram showing an example of the data structure of the product master file F1. As shown in FIG. 3, the product master file F1 includes the product name, product price (unit price), classification code (classification 1 code, Product information such as classification 2 code), tax exemption classification code, and dangerous goods classification code is set. Dangerous goods classification codes are assigned to products that require careful handling, such as sprays that are prohibited from being carried onto aircraft.

Products are classified using multiple classification codes, and these multiple classifications are constructed hierarchically.

That is, as shown in FIG. 3, products are classified into a plurality of categories according to category 1 (higher category), which is a rough category. Further, each category 1 is further classified in detail by category 2 (lower category), which is a more detailed category. That is, the upper classification 1 is divided into a plurality of classifications by the lower classification 2 than the classification 1, and includes at least one lower classification 2.

Note that in terms of the hierarchical structure, the product code assigned to each product can be regarded as a lower classification than classification 2. The product code can be considered the most detailed classification, that is, the lowest classification.

Next, the tax exemption classification file F2 will be explained. FIG. 4 is a diagram showing an example of the data structure of the tax exemption classification file F2. As shown in FIG. 4, tax exemption category names are set in the tax exemption category file F2 in association with tax exemption category codes. The names of tax exemption categories are "consumables", "general goods", and "not eligible for tax exemption". "Consumables" are tax-exempt items that are exempt from taxes on goods sold to non-residents such as foreign tourists, and include items such as foods, beverages, medicines, and cosmetics. . "General goods" are also tax-exempt items, and are goods used in daily life other than consumables. “Not eligible for tax exemption” refers to items that are not eligible for tax exemption. The tax exemption classification code for “consumables” is “01”. The tax exemption classification code for “general goods” is “02”. The tax exemption classification code for “not eligible for tax exemption” is “03”.

Next, the tax exemption setting value file F3 will be explained. FIG. 5 is a diagram showing an example of the data structure of the tax exemption setting value file F3. As shown in FIG. 5, setting values are set in the tax exemption setting value file F3 in association with tax exemption category codes. The set value serves as a guideline for registering sales as tax exempt in each category. In the example shown in FIG. 5, the set value for consumables with tax exemption classification code "01" is 5,000 yen to 500,000 yen. Furthermore, the set value for general goods (goods used in daily life other than consumables) with tax exemption classification code "02" is an amount exceeding 10,000 yen.

Next, the transaction history DB1 will be explained. FIG. 6 is a diagram showing an example of the data structure of the transaction history DB1. As shown in FIG. 6, the transaction history DB1 stores transaction information of transactions processed by each POS terminal 2 as a transaction history.

The transaction history includes the transaction number for identifying each transaction (stored in the transaction number section DB11), the transaction date and time when the transaction was performed (stored in the transaction date and time section DB12), and the POS terminal 2 at which the transaction was performed. The register number (stored in the register number section DB 13) that identifies the register is included. Further, the transaction history includes the product code, unit price, number of items (stored in the product information section DB 15), etc. of each product registered for sale. Furthermore, a flag (stored in the flag section DB14) is set in the transaction history DB1 in association with the transaction number. The flag is used to determine whether tax exemption processing, which will be described later, has been applied to the transaction.

In the example shown in Figure 6, a transaction with a flag of "0" means a transaction that has not been tax exempted, and a transaction with a flag of "1" means a transaction that has been tax exempted. . Therefore, in the case of FIG. 6, the transaction with transaction number "0425" is tax exempted, and the transactions with transaction number "0426" and transaction number "0427" are not tax exempted.

Note that the transaction history DB1 functions as an electronic journal that stores transaction history data.

The control unit 400 distributes the product master file F1, the tax exemption category file F2, and the tax exemption setting value file F3 to the POS terminal 2 at a predetermined timing according to the control program 481.

The pending history DB2 will be described later.

Next, the POS terminal 2 will be explained. The POS terminal 2 is assigned a unique cash register number and placed at the payment location. The POS terminal 2 is a terminal for performing transaction processing based on a product code input by an operator (cashier).

The POS terminal 2 performs transaction processing related to the sale of products sold in the store. When the operator operates the POS terminal 2, the POS terminal 2 executes sales registration processing and payment processing for the products to be sold. Note that the combination of sales registration processing and payment processing is referred to as transaction processing.

Sales registration processing involves optically reading a barcode or other code attached to a product to be sold, inputting the product code, and reading out the product name and price (product This refers to the process of displaying product information (product information) and storing product information in a buffer. Payment processing includes displaying the total amount of the transaction based on the product information stored in the buffer during the sales registration process, calculating and displaying change based on the deposit deposited by the customer, and issuing change. This refers to the process of instructing a change machine to issue a receipt with product information and payment information (total amount, deposited amount, amount of change, etc.) printed.

FIG. 7 is a block diagram showing the hardware configuration of the POS terminal 2. As shown in FIG. As shown in FIG. 7, the POS terminal 2 includes a control section 300 having a computer configuration including a CPU 31, a ROM 32, a RAM 33, and the like.

The CPU 31 executes various calculation processes and controls each section. The ROM 32 permanently stores fixed data. The RAM 33 stores variable data in a rewritable manner and is used as a work area. The CPU 31, ROM 32, and RAM 33 are configured to be connected via a bus 34.

In the RAM 33, a tax exemption amount table T is formed which totals tax exemption amounts, which will be described later.

The POS terminal 2 further includes a controller 35, a keyboard 21, a display section 22, a printer 23, a scanner 24, a passport reader 25, a communication I/F 26, and a memory section 27.

The keyboard 21, display section 22, printer 23, scanner 24, and passport reader 25 are connected to a control section 300 via a controller 35 and a bus 34. The control unit 300 controls each of the above units (keyboard 21, display unit 22, printer 23, scanner 24, and passport reader 25).

The display unit 22 is an example of a display device, and is a liquid crystal display device with a touch panel provided on the display surface, and displays information for the operator in the form of images. The touch panel and keyboard 21 accept operator operations. The printer 23 prints receipts and journals. The scanner 24 optically reads codes such as barcodes and two-dimensional codes attached to products.

The keyboard 21 has various keys arranged in blocks. Various keys include, for example, a number key for inputting product codes and amounts, etc., a subtotal key for declaring the calculation of the total sales amount, a current total key for declaring closing with cash in sales processing, and various other keys. These include a PLU key for specifying a product, a confirmation key for confirming a number input using the number keys, and a clear key.

The keyboard 21 also includes a tax exemption declaration key K1, a product name list output key K2, a post-settlement tax exemption application key K3, and a register minus key K4. The tax exemption declaration key K1 is an operator that declares that tax exemption processing will be performed for the transaction. The product name list output key K2 is an operator for instructing output of a list of products eligible for tax exemption (product name list). The post-settlement tax exemption application key K3 is an operator that declares that post-settlement tax exemption application processing will be performed in order to perform tax exemption processing on past transactions. The register minus key K4 is an operator for declaring cancellation of a transaction.

The passport reader 25 is a reader device that reads information held in a passport. In the embodiment, the passport reader 25 has an optical character recognition (OCR) function that optically reads character strings written on a passport.

The communication I/F 26 connects the POS terminal 2 to the network 3 provided within the store. Through this connection, the server 4, which is a host device, and the control unit 300 can communicate online with each other.

The memory unit 27 is composed of an HDD (Hard Disc Drive), a flash memory, etc., and maintains the stored contents even if the power is cut off.

The memory unit 27 stores an operating system, control programs 271 such as various computer programs, and various data files. The data files include a product master file F1, a tax exemption category file F2, a tax exemption setting value file F3, etc. distributed from the server 4.

The control program 271 executed by the POS terminal 2 of the embodiment is a file in an installable or executable format and can be stored on a computer such as a CD-ROM, a flexible disk (FD), a CD-R, or a DVD (Digital Versatile Disk). Provided recorded on a readable recording medium.

Further, the control program 271 executed by the POS terminal 2 of the embodiment may be stored on a computer connected to a network such as the Internet, and may be provided by being downloaded via the network. Further, the control program 271 executed by the POS terminal 2 of the embodiment may be provided or distributed via a network such as the Internet.

Further, the control program 271 executed by the POS terminal 2 of the embodiment may be configured to be provided by being incorporated in the ROM 32 or the like in advance.

Next, a control process executed by the control unit 300 of the POS terminal 2 according to the control program 271 will be described.

FIG. 8 is a functional block diagram showing the functional configuration of the POS terminal 2. As shown in FIG. The control unit 300 causes the tax exemption processing means 310 and the post-settlement tax exemption application means 320 to function according to various programs including the control program 271 stored in the ROM 32 and the memory unit 27.

The tax exemption processing unit 310 is a functional unit that performs tax exemption processing to exempt products eligible for tax exemption from paying taxes. The tax exemption processing by the tax exemption processing means 310 is performed at the time of payment.

The post-settlement tax exemption application unit 320 is a functional unit that performs post-settlement tax exemption application processing to refund the tax portion from the total price paid for tax-exempt products in a tax-inclusive sales transaction that has already been settled. The post-settlement tax exemption applying means 320 includes functional units of a specifying means 321, a calculating means 322, a detailed display means 323, a holding means 324, a resuming means 325, an adding means 326, a refund means 327, and a receipt issuing means 328. I'm here.

The designating means 321 designates a transaction for which tax exemption is not applied, that is, for which tax exemption processing is not performed. Specifically, the designation here refers to extracting one or more transactions that include products that are eligible for tax exemption but to which tax exemption has not been applied, from the transaction history DB 1 based on information input by the operator. The information input by the operator is, for example, a signal output by the scanner 24 when the operator causes the scanner 24 to read a barcode attached to a receipt. The signal is responsive to a barcode, which includes information (eg, transaction number) identifying past transactions displayed on the receipt. Note that although a barcode is used as an example here, a two-dimensional code or the like may be used in practice.

The calculation means 322 calculates the total price of products that are eligible for tax exemption but to which tax exemption has not been applied (hereinafter referred to as processing target products) based on the data of one or more transactions extracted by the specifying means 321. These specifying means 321 and calculating means 322 realize a totaling means for calculating the above-mentioned total amount based on the data of settled transactions.

The details display means 323 causes the display section 22 to display a registration details screen G8 (see FIG. 24, described later). The registration details screen G8 displays a list summarizing the names, prices, etc. of the products to be processed that are included in the total amount by the calculation means 322.

The retention means 324 stores the tax exemption information in a predetermined storage unit when the total amount calculated by the calculation means 322 is less than a predetermined value (a reference amount determined by the tax exemption system). The tax exemption information is data (processing data) used in the post-payment tax exemption application process, and is various information about the product to be processed. The predetermined storage unit is, for example, the HDD 48 of the server 4. The processing data is stored in the suspension history DB2 held by the HDD 48.

Here, FIG. 9 is a diagram showing the storage contents of the reservation history DB2 in a table format. The suspension history DB2 stores, for example, transaction numbers, suspension dates, register numbers, receipt amounts, suspension numbers, and the like. These are stored in the transaction number section DB21, reservation date section DB22, register number section DB23, receipt amount section DB24, and reservation number section DB25, respectively.

For example, one record is created in the hold history DB 2 for each receipt handed over by a customer to an operator. The transaction number is a number that identifies the transaction indicated by the receipt. The transaction number is the same as that in the transaction number section DB11 of the transaction history DB1. In other words, the transaction specified by the transaction number recorded in the transaction number section DB11 and the transaction specified by the transaction number recorded in the transaction number section DB21 are the same transaction. Further, the cash register number and receipt amount are information on the transaction specified by the transaction number, and are based on information recorded in the transaction history DB1.

The suspension date is the date on which the post-settlement tax exemption application processing was suspended, that is, the date on which the processing for registering the record is being performed. The hold number is an example of an identification code, is common to all records related to one hold, and is unique for each hold.

Further, the holding unit 324 causes the printer 23 to save processing data in the holding history DB2 and issue a holding receipt R5 (see FIG. 29, described later). The pending receipt R5 is an example of a pending slip, and has the above-mentioned identification code, total amount, shortage amount, etc. printed thereon. The shortfall here is the amount obtained by subtracting the total amount from the lower limit for tax exemption. Further, the identification code is indicated by a barcode or two-dimensional code that can be read by the scanner 24.

The restarting means 325 reads the corresponding processing data from the suspension history DB 2 on the condition that a predetermined operation has been received. The predetermined operation is, for example, for the operator to cause the scanner 24 to read the identification code of the pending receipt received from the customer. The restarting means 325 identifies the corresponding processing data using the identification code.

If the total amount calculated by the calculation means 322 is less than a predetermined amount, the additional means 326 accepts an additional purchase of tax-exempt products on the spot, and adds the price of the product for the additional purchase to the total amount. do.

The refund means 327 manages the refund of the difference (ie, tax amount) between the tax-included price paid by the customer when purchasing the product and the price after tax exemption is applied. In other words, the refund means 327 instructs the operator to refund a predetermined amount to the customer, and also updates the transaction history DB1 and the pending history DB2 as appropriate.

The receipt issuing unit 328 has a function of printing and issuing a receipt or the like including information on products exempted from tax through post-settlement tax exemption application processing.

FIG. 10 is a flowchart showing the flow of control processing of the POS terminal 2. The control unit 300 determines whether a product code for identifying a product has been input using the scanner 24 (step S11). If it is determined that the input has been made (Yes in step S11), the control unit 300 searches the product master file F1 according to the input product code and determines the product based on product information such as the product name and unit price. Execute sales registration processing to calculate the registration amount. Next, the control unit 300 stores the product information of the product for which the sales registration process has been performed in the RAM 33 (step S12). At this time, the display unit 22 is displaying the product registration screen G1 under the control of the control unit 300. FIG. 11 is a diagram showing an example of the product registration screen G1.

Further, if it is determined that the product code has not been input (No in step S11), the control unit 300 determines whether or not the current total key provided on the keyboard 21 for declaring to end the transaction has been operated. (Step S13). If it is determined that the transaction has been operated (Yes in step S13), the control unit 300 executes a payment process for calculating the total amount based on the registered price of the product and product information for the transaction (step S14). In this payment process, the control unit 300 calculates the total amount including the amount of tax such as consumption tax on the product purchased by the customer.

Next, the control unit 300 issues a receipt R0 on which purchase details x, payment record y, etc. are printed on receipt paper (step S15). FIG. 12 is a diagram showing an example of a normal receipt R0. The purchase details x are details of the purchased products (a record of the product name, number of purchased items, and price). Moreover, the settlement record y is a record of the exchange of money, such as the price, deposited amount, and change. In addition to the above-mentioned items, the receipt R0 displays a business name a, a transaction date d, a transaction number e that specifies the transaction, a cash register number f, and a barcode w. In the business name a section, characters or a logo mark indicating the name or designation of the business that manages the store are displayed. The barcode w is a coded version of the transaction number e.

Next, the control unit 300 transmits product information, etc. (transaction number, transaction date and time, cash register number, product code, unit price, number of items, etc.) of the transaction processed product to the server 4 (step S16). The server 4 stores the received information in the transaction history DB1. Specifically, the control section 400 of the server 4 stores the transaction number in the transaction number section DB11. The control unit 400 stores the transaction date and time in the transaction date and time section DB12. The control unit 400 stores the cash register number of the POS terminal 2 that processed the transaction in the cash register number unit DB 13. The control section 400 stores the product code, unit price, and score of the traded product in the product information section DB 15. Further, the control unit 400 stores in the flag unit DB 14 a flag “0” indicating that tax exemption processing is not performed for the transaction in association with the transaction number of the transaction.

If it is determined that the current total key has not been operated (No in step S13), the control unit 300 determines whether or not the tax exemption declaration key K1 has been operated (step S21). If it is determined that the operation has been performed (Yes in step S21), it is assumed that a tax exemption process has been declared, and the control unit 300 executes the tax exemption process shown in FIG. 13 (step S22).

[Normal tax exemption processing]
Here, the normal tax exemption process executed in step S22 when the tax exemption declaration key K1 is operated will be described in detail with reference to FIGS. 13 to 19. FIG. 13 is a flowchart showing the flow of normal tax exemption processing. The control unit 300 operates the passport reader 25. Next, the control unit 300 determines whether the passport reader 25 has read a predetermined character string from the passport (step S51). Examples of such character strings include passport number, name, nationality, date of birth, and the like. The control unit 300 displays a message on the display unit 22 indicating that the passport is being read until a predetermined character string is read from the passport.

The control unit 300 causes the display unit 22 to display a guide screen (not shown) that prompts the user to read the passport. The operator of the POS terminal 2 opens a page containing information regarding the tax exemption system on the passport presented by the customer (non-resident), and holds the page over the passport reader 25. In response to this operation, the control unit 300 reads a predetermined character string from the passport.

The control unit 300 waits until the passport is read (No in step S51), and if it is determined that the passport has been read (Yes in step S51), the control unit 300 displays a confirmation message on the display unit 22 to confirm the character string read in step S51. Screen G2 (see FIG. 14) is displayed (step S52).

The confirmation screen G2, an example of which is shown in FIG. 14, is an example of reading the character strings of the passport number, name, nationality, and date of birth among the items written on the passport. On the confirmation screen G2, the character strings read in step S51 are displayed for each item (matter).

Here, a delete button B1 is provided in association with each item on the confirmation screen G2. The control unit 300 determines whether or not the delete button B1 is operated (step S53). If it is determined that the operation has been performed (Yes in step S53), the control unit 300 deletes the character string read for the corresponding item (step S54), and returns to step S53. For example, if there is an error in the character string of any item among the character strings of each item read in step S51, the erroneous character string can be deleted by operating the delete button B1. . Note that the control unit 300 displays a confirmation screen G2 with the character string of the item deleted in step S54 left blank.

Further, the control unit 300 displays, on the confirmation screen G2, a confirm button B2, a reread button B3, and a cancel button B4, which correspond to the confirmation reception means of the embodiment. Next, if the control unit 300 determines that the delete button B1 has not been operated (No in step S53), it determines whether the reread button B3 has been operated (step S55). If it is determined that the re-reading button B3 has been operated (Yes in step S55), the control unit 300 returns the process to step S51 to read the character string from the passport again. The control unit 300 deletes the previously read character string in response to the operation of the reread button B3.

If it is determined that the re-read button B3 has not been operated (No in step S55), the control unit 300 determines whether the cancel button B4 has been operated (step S56). If it is determined that the cancel button B4 has been operated (Yes in step S56), the control unit 300 deletes all the read character strings (step S57) and returns to step S51. In response to the operation of the cancel button B4, the control section 300 returns the display screen of the display section 22 from the confirmation screen G2 to the product registration screen G1.

If it is determined that the cancel button B4 has not been operated (No in step S56), the control unit 300 determines whether or not the confirm button B2 has been operated (step S58). When the control unit 300 determines that the confirm button B2 has been operated (Yes in step S58), the tax exemption processing means 310 executes tax exemption processing to exempt the payment of taxes such as consumption tax (step S59). Further, if it is determined that the confirm button B2 has not been operated (No in step S58), the control unit 300 returns the process to step S53.

Next, the tax exemption process in step S59 will be explained.

First, the control unit 300 determines the existence of a tax-exempt product that is subject to tax exemption by referring to the tax-exempt classification code of the product master file F1 for already registered registered products. If there is a tax exempt product, the control unit 300 performs a process of adding the tax exempt amount for each registered product group (general goods group/consumables group) that is tax exempt to the tax exempt amount table T (RAM 33).

The handling of tax-exempt products by tax type is as follows.

If the registered product eligible for tax exemption is tax-inclusive, the control unit 300 adds the tax-inclusive amount of the registered amount to the tax-exempt amount table T as the tax-exempt amount. More specifically, in the case of a tax-inclusive product, the control unit 300 sets the difference between the registered amount before tax exemption and the registered amount after tax exemption as the tax exempt amount. An example is shown in the formula below.
Unit price before tax exemption: 1080 yen - Unit price after tax exemption: 1000 yen = Tax exemption amount: 80 yen

If the registered product eligible for tax exemption is tax-excluded, the control unit 300 adds the registered amount to the tax exempt amount table T as the tax exempt amount. More specifically, in the case of a tax-excluded product, the control unit 300 sets the tax-excluded amount relative to the registered amount as the tax exemption amount.

Note that if the registered product is a product that is not eligible for tax exemption, the control unit 300 does not add the registered amount to the tax exempt amount table T as the tax exempt amount.

Next, the control unit 300 determines whether the tax exempt amount in the tax exempt amount table T satisfies the set value (reference amount) in the tax exempt set value file F3. In the tax exemption setting value file F3 of the embodiment, the setting values for foods, beverages, medicines, cosmetics, and other consumables are from 5,000 yen to 500,000 yen. Furthermore, the set value for general goods (goods used in daily life other than consumables) is an amount exceeding 10,000 yen.

If the control unit 300 determines that the tax-exempt amount of the consumables satisfies the set value (5,000 yen to 500,000 yen), the control unit 300 performs tax exemption processing to exempt the tax on the tax-exempt amount. In addition, if the control unit 300 determines that the amount eligible for tax exemption for general goods (articles used for everyday life other than consumables) satisfies the set value (amount exceeding 10,000 yen), the amount eligible for tax exemption Tax exemption processing will be carried out to exempt from taxes.

Further, the control unit 300 displays an error on the display unit 22 if the tax exempt amount for the consumables in the tax exempt amount table T exceeds the upper limit of the set value (500,000 yen).

FIG. 15 is a diagram showing an example of the error screen G3. On the error screen G3, the control unit 300 provides a message such as "The tax exemption limit has been exceeded. Please cancel the product. Excess amount: XX, XXX yen." If the clear key of the keyboard 21 is operated while the error screen G3 is being displayed, the control unit 300 erases the error screen G3.

On the other hand, when the tax exemption amount is less than the standard amount, the control unit 300 conventionally provides an error display (not shown) to inform that the standard amount is not met, similar to when the tax exemption upper limit value is exceeded. In this case, either settle the transaction as one in which tax exemption does not apply, or cancel the transaction.

Return to the flowchart (FIG. 13). Following the tax exemption process (step S59), the control unit 300 displays the product registration screen G4 (step S60). FIG. 16 is a diagram showing an example of the product registration screen G4. On the product registration screen G4, a tax exemption indicator I labeled "Tax Exemption" is displayed. The control unit 300 displays the tax exemption indicator I on the product registration screen G4 to notify the operator that the transaction is a tax exemption declaration transaction. On the product registration screen G4, the tax amount is displayed as "0 yen" due to tax exemption due to tax exemption processing (step S59), and the total displayed amount is the amount after tax exemption processing (the amount after reducing the exempted tax). ) is displayed. Furthermore, in the product information list on the product registration screen G4, the word "exempt" is displayed in the row of products to which tax exemption is applied.

The control unit 300 determines whether the current total key has been operated (step S61). In step S61, the control unit 300 waits until it is operated (No in step S61). If it is determined that the operation has been performed (Yes in step S61), the control unit 300 executes a payment process to settle the price of the product for the transaction (step S62). In this payment process, taxes such as consumption tax are not added to the sold product, and the payment is made at the amount after tax exemption is applied, which does not include the tax amount.

Next, the control unit 300 transmits product information, etc. (transaction number, transaction date and time, cash register number, product code, unit price, number of points, etc.) of the product for which payment has been processed to the server 4 (step S63). Upon receiving the product information, the server 4 stores the received information in the transaction history DB1. Specifically, the control section 400 of the server 4 stores the transaction number in the transaction number section DB11. The control unit 400 stores the transaction date and time in the transaction date and time section DB12. The control unit 400 stores the cash register number of the POS terminal 2 that processed the transaction in the cash register number unit DB 13. The control section 400 stores the product code, unit price, and score of the traded product in the product information section DB 15. Then, the control unit 400 stores in the flag unit DB 14 a flag “1” indicating that tax exemption processing has been performed for the transaction in association with the transaction number of the transaction.

Next, the control unit 300 prints and issues the product information, payment information, tax exemption amount, etc. of the product for which payment has been processed on a receipt paper (step S64). In this step, the control unit 300 prints, for example, one purchase pledge, two purchase record sheets, and one receipt.

FIG. 17 is a diagram showing an example of the purchase pledge R1. Purchase pledge R1 certifies the fact of purchase of duty-free goods. The purchase pledge R1 is submitted to the business operator of the duty-free shop as a copy of the store, attached to a predetermined document (purchaser pledge (separate from the purchase pledge R1 in the form of a receipt)).

Purchase pledge R1 includes the name of the businessman who runs the duty-free shop (a), the signature of the local tax office (b), the store location of the duty-free shop (c), the transaction date (d), the transaction number (e), the cash register number (f), and the details of the product (item name). g, quantity and price for each item name (h), total amount of all items i, total amount of each of general items and consumables j, and tax exemption amount k.

The purchase pledge R1 also has a column for printing character strings for each item confirmed on the confirmation screen G2. Specifically, character strings confirmed on the confirmation screen G2 regarding the following items are printed on the purchase pledge R1.
・Passport number...l
・Purchaser's nationality...m
・Purchaser's name...n
・Purchaser's date of birth...o

Note that for items (character strings) deleted by operating the delete button B1 on the confirmation screen G2, only the item name is printed. In this case, the operator writes the contents of the item directly on the document (purchaser oath).

Further, the layout of the purchase pledge R1 is not limited to the example shown in FIG. 17. For example, a statement stating that the item will be exported after purchase (in the case of consumables, a promise to be exported within 30 days from the date of purchase), a signature space for the purchaser, etc. may be printed.

Next, the purchase record slip, which is a receipt, will be explained. FIG. 18 is a diagram showing an example of the purchase record form R2. The purchase record form R2 certifies the fact of purchase of tax-free goods. Two purchase record slips R2 are printed as attachments to a predetermined document (purchase record slips (separate from purchase record slips R2 in the form of receipts)) and as store copies. The attached purchase record slip R2 is pasted on the above-mentioned predetermined document (purchase record slip). This document (purchase record slip) will be pasted on your passport and stamped.

Purchase record form R2 includes the name (a) of the business operator who operates the duty-free shop, the signature of the local tax office (b), the store location of the duty-free shop (c), the transaction date (d), the transaction number (e), the cash register number (f), and the product details (item name). g, quantity and price for each item name (h), total amount of all items i, total amount of each of general items and consumables j, and tax exemption amount k.

Furthermore, the purchase record form R2 has a column for printing the character strings of each item confirmed on the confirmation screen G2. Specifically, character strings confirmed on the confirmation screen G2 regarding the following items are printed on the purchase record form R2.
・Passport number...l
・Purchaser's nationality...m
・Purchaser's name...n
・Purchaser's date of birth...o

For items (character strings) deleted by operating the delete button B1 on the confirmation screen G2, only the item name is printed and written directly on the document (purchase record form), similar to the purchase pledge R1. shall be. Furthermore, the layout of the purchase record form R2 is not limited to the example shown in FIG. 18.

Next, receipts will be explained. FIG. 19 is a diagram showing an example of a receipt R3 of a tax-free transaction. Receipt R3 is given to the purchaser after the transaction.

Receipt R3 includes the name (a) of the business operator who operates the duty-free shop, transaction date (d), transaction number (e), cash register number (f), item details (item name (g), quantity and price of each item (h)), and information on all items. Includes the total amount i. In the receipt R3, the letter p for "exempt" is added to the name of the product exempted from tax. Further, on the receipt R3, a message q indicating that the transaction is tax-free is printed, ``A tax-free transaction has been performed.'' Further, a barcode w that encodes the transaction number e is printed on the receipt R3.

Note that if the information stored in the transaction history DB1 does not function as a journal, the control unit 300 executes journal printing corresponding to the purchase record slip R2 and receipt R3. At this time, the control unit 300 prints all or part of the character strings of the items confirmed on the confirmation screen G2 on the journal corresponding to the receipt R3.

In this manner, the control unit 300 reads a predetermined character string from the passport using the passport reader 25, and displays the read character string on the confirmation screen G2 for the operator to confirm. Next, after confirmation by the operator, the control unit 300 prints the character string displayed on the confirmation screen G2 on the purchase pledge R1 or the like. As a result, according to the POS terminal 2 of the embodiment, complicated procedures such as handwriting on a purchaser's oath and purchase record slip for each product purchase are not necessary, so procedures related to tax exemption can be efficiently performed. Can be done.

Further, the control unit 300 automatically performs tax exemption processing when the tax exemption standard amount (consumables: 5,000 yen, general goods: 10,000 yen) is exceeded for each tax exemption classification unit (consumables, general goods). As a result, according to the POS terminal 2 of the embodiment, there is no need for a tax exemption registration operation at the operator's discretion, and it is possible to execute a sales registration process for products that corresponds to the revision of the tax exemption system.

Further, upon receiving the operation of the product name list output key K2, the control unit 300 executes a printing process to output a product name list (not shown) of products eligible for tax exemption. Here, the timing at which the operation of the product name list output key K2 is accepted does not particularly matter. For example, if an operation of the product name list output key K2 is received during the sales registration process, the control unit 300 executes the list printing process along with the above-described printing process. Further, when an operation of the product name list output key K2 is received outside of the sales registration process, the control unit 300 executes the list print process after inputting the transaction number, etc. of the transaction that is the target of the list print process. .

In the list printing process of the embodiment, one product name list is printed. The product name list is a document that lists products that are subject to tax exemption processing. The product name list is attached to the bag or box in which the products eligible for tax exemption processing are packaged.

The product name list includes the name of the business operator who operates the duty-free shop, the product name of the product subject to tax-free processing, and the quantity and price for each product name. Note that among the products eligible for tax exemption processing, only consumables may be printed on the product name list. In this case, it is assumed that whether or not a product is a consumable item is determined based on the tax exemption classification code in the product master file F1 and tax exemption classification file F2. Further, in the case where the POS terminal 2 is separately provided with a label printer, the control unit 300 may print the product name list using the label printer.

In this manner, the POS terminal 2 can output a list of product names of products eligible for tax exemption in response to the operation of the product name list output key K2. As a result, according to the POS terminal 2 of the embodiment, if it is stipulated by law to indicate the product name on the packaging of products eligible for tax exemption, it is possible to easily issue a list of product names. procedures can be carried out efficiently.

Return to the flowchart (FIG. 10). If it is determined in step S21 that the tax exemption declaration key K1 has not been operated (No in step S21), the control unit 300 determines whether the post-settlement tax exemption application key K3 for performing tax exemption processing on past transactions has been operated. (Step S31). If it is determined that the operation has been performed (Yes in step S31), the control unit 300, as the post-settlement tax exemption application means 320, executes the post-settlement tax exemption application process (step S32).

[Post-payment tax exemption application processing]
20-1 and 20-2 are flowcharts schematically showing the flow of the post-settlement tax exemption application process. First, the control unit 300 executes the processes of steps S71 to S78. The processing in steps S71 to S78 is the same as the processing in steps S51 to S58 described above, so a description thereof will be omitted. Note that if the cancel button B4 is operated (Yes in step S76), the control unit 300 returns to step S71 after deleting all the character strings read from the passport (step S77).

Subsequently, the control unit 300 performs transaction designation processing (step S81) as the designation means 321. In this process, the control unit 300 first displays the transaction search screen G5 on the display unit 22.

FIG. 21 is a diagram showing an example of the transaction search screen G5. The transaction search screen G5 has a register number column A51, a date column A52, a transaction number column A53, a receipt amount column A54, a confirm button B51, and a return button B52.

The register number column A51 is a column for inputting a register number that identifies the POS terminal 2 where the transaction for which tax exemption is to be applied after payment (hereinafter referred to as a transaction to be processed) has been performed. The column A51 displays, as an initial value, the cashier number assigned to the POS terminal 2 equipped with the display section 22 that is displaying the transaction search screen G5. The date column A52 is a column for inputting the date on which the transaction to be processed was performed (transaction date), and displays the current date as an initial value. The transaction number column A53 is a column for inputting the transaction number of the transaction to be processed. The receipt amount column A54 is a column for inputting the amount paid in the transaction to be processed.

The confirm button B51 is a button for confirming the input contents in each of the columns A51 to A54 and declaring moving to the next process. The return button B52 is a button for returning the screen. That is, when the return button B52 is operated, the control unit 300 stops the transaction designation process and returns the display on the display unit 22 to the confirmation screen G2.

Next, the control unit 300 uses the scanner 24 to read the barcode w printed on the receipt R0 in step S15, thereby determining whether the transaction number e included in the barcode w has been input. The control unit 300 waits until the transaction number e is input, and when determining that it has been input, queries the server 4 and retrieves history information of past transactions corresponding to the corresponding transaction number e from the transaction history DB 1 of the server 4. receive. Next, the control unit 300 determines whether or not the following three conditions are satisfied for the transaction of the received history information.

The first condition is that the flag stored in the flag unit DB14 for the transaction read from the transaction history DB1 is "0". The second condition is that the transaction history DB1 includes products eligible for tax exemption. The third condition is that the transaction date is the same as the transaction date in the transaction history DB1 read earlier. If all of these three conditions are met, the control unit 300 causes the display unit 22 to display a list screen G6 (see FIG. 22) based on the received transaction history information.

Note that if the transaction with the input transaction number does not satisfy one or more of the three conditions, the control unit 300 displays an error message (not shown) on the display unit indicating that tax exemption cannot be applied to the transaction. 22 and waits for the next operation.

FIG. 22 is a diagram showing an example of the list screen G6. The list screen G6 includes a list L1, a confirm button B61, a cancel button B62, and a manual button B63. The list screen G6 is displayed when one transaction is identified while the transaction search screen G5 is being displayed. The control unit 300 also accepts transaction designation during the display of the list screen G6 in the same manner as during the display of the transaction search screen G5. When a transaction is specified, the number of transactions displayed in the list L1 increases.

The list L1 displays a list of identification information (register number, transaction date, transaction number, receipt amount) of each transaction to be processed. The confirm button B61 is a button for confirming the transaction designation (step S81) and declaring moving to the next process (step S82). The cancel button B62 is a button for returning the screen. That is, when the cancel button B62 is operated, the control section 300 clears the specified transaction and returns the display on the display section 22 to the transaction search screen G5. The manual button B63 is a button for displaying or enabling use of numerical keys and the like used for manual input.

Note that the transactions displayed on the list screen G6 can be excluded (deleted) from the processing targets by operating the keyboard 21 or the touch panel. Alternatively, by selecting a transaction displayed on the list screen G6, a list of tax exempt products included in the transaction may be displayed.

In step S82, the control unit 300, as the calculation means 322, calculates the total price of the products to be processed included in the transaction specified in step S81 (the transaction to be processed). Next, the control unit 300 determines whether the total amount calculated in step S82 has reached the reference amount (step S83).

In step S83, if the total amount has reached the reference amount (Yes in step S83), the control unit 300 first displays the confirmation screen G7 on the display unit 22. FIG. 23 is a diagram showing an example of the confirmation screen G7. Here, the confirmation screen G7 shown in FIG. 23 is a screen when the total amount has reached a predetermined amount. The confirmation screen G7 is a screen for showing the total amount, and has a confirmation button B71 and a list button B72.

When the list button B72 is operated on the confirmation screen G7, the control unit 300 displays the registration details screen G8 as the details display means 323. FIG. 24 is a diagram showing an example of the registration details screen G8.

The registration details screen G8 displays a list of the names and prices of the products to be processed on which the total price calculated in step S82 is based. In the example shown in FIG. 24, the registration details screen G8 displays the product code, product name, quantity, unit price, discount or discount, amount, and classification (consumables or general products) for each product. While displaying the registration details screen G8, the control unit 300 accepts requests such as deletion of the product to be processed and correction of the value.

Further, the registration details screen G8 has a return button B81. When the return button B81 is operated, the control section 300 returns the display on the display section 22 to the confirmation screen G7.

When the confirmation button B71 is operated on the confirmation screen G7, the control unit 300 performs refund processing (step S84). In the refund processing, the control unit 300, as the refund means 327, calculates the refund amount determined based on the total amount and updates the transaction history DB1. That is, the control unit 300 changes the flag stored in the flag unit DB14 of the transaction history DB1 for the transaction to be processed from "0" to "1". Further, the control unit 300 newly registers a record of the refund in a predetermined storage unit (for example, transaction history DB1). At the time of this registration, the control unit 300 assigns a new transaction number to the refund. The transaction number enables the record of the refund to be identified in the predetermined storage unit. For example, if the transaction history DB 1 also serves as a storage unit for registering refund records, this can be done by entering a code indicating refund processing in the product code column and the refund amount in the unit price column.

Further, in response to the operation of the above-described confirm button B71, the control unit 300 causes the printer 23 to print and issue a receipt or the like including information on the product to be processed, as the receipt issuing means 328. What is issued at this time are a purchase pledge R1 (FIG. 17), a purchase record slip R2 (FIG. 18), and a refund receipt R4 (FIG. 27, described later).

Furthermore, in response to the operation of the above-described confirm button B71, the control unit 300 causes the display unit 22 to display a totalizing screen G9, an example of which is shown in FIG. 25(a). The counting screen G9 indicates to the operator that the processing is in progress and the progress of the processing using text and image indicators. After completing the DB update and printing/issuance, the control unit 300 causes the display unit 22 to display a completion screen G10, an example of which is shown in FIG. 25(b).

The completion screen G10 has a close button B101. When the close button B101 is operated, the control unit 300, as the refund means 327, instructs the operator to refund a predetermined amount to the customer. That is, the control unit 300 causes the display unit 22 to display the payment screen G11.

FIG. 26 is a diagram showing an example of the payment screen G11. The payment screen G11 not only shows the refund amount but also includes text and illustration guidance to the operator such as "Please do not forget to hand over your receipt."

Here, if there is a change machine (not shown) linked to the POS terminal 2, when the close button B101 on the completion screen G10 is operated, the change machine dispenses money equivalent to the refund amount, so the operator can Compare it with the amount shown and return it to the customer along with a refund receipt R4.

Furthermore, if it is not a change machine but a drawer (not shown) that is linked to the POS terminal 2, the drawer will open when the close button B101 on the completion screen G10 is operated, so the operator can collect the amount shown on the payment screen G11. The coins are taken out of the drawer and returned to the customer along with the refund receipt R4.

FIG. 27 is a diagram showing an example of the refund receipt R4. The refund receipt R4 is a document that describes the transaction to be processed and the refund amount. Refund receipt R4 is given to the non-resident customer.

Further, the refund receipt R4 includes the name a of the business operator who operates the duty free shop, the transaction date d when the post-settlement tax exemption application process was performed, the transaction number e, and the cashier number f. Further, the refund receipt R4 includes a transaction number r, a cash register number s, and a refund amount t of each transaction to be processed. Further, the refund receipt R4 has a message "Tax exemption has been applied to the above transaction." u indicating that tax exemption has been applied after payment. Furthermore, a barcode w is printed on the refund receipt R4, which is a code of the transaction number e of the above-mentioned post-settlement tax exemption application process.

Note that the payment screen G11 has a close button B111. When the close button B111 is operated, the control unit 300 finishes the refund process (step S84), finishes the post-settlement tax exemption application process (step S32), and returns to step S11.

Next, a case where the total amount has not reached the reference amount (No in step S83) will be described. In this case, the control unit 300 first causes the display unit 22 to display a confirmation screen G7, an example of which is shown in FIG. In this case, the confirmation screen G7 displays, in addition to the state shown in FIG. 23, a hold button B73, an add button B74, and a message M1. When displaying the confirmation screen G7 for this state, the control unit 300 disables the confirmation button B71.

Message M1 informs of the shortfall in the total amount. In other words, the message M1 indicates that the total price of the products to be processed has not reached the standard amount, and the difference from the standard amount. The hold button B73 accepts an operation to instruct the start of the hold process (step S85). The add button B74 accepts an operation to instruct the start of additional processing (step S86).

In the suspension process (step S85), the control unit 300 first stores the processing data in the suspension history DB2. Further, the control unit 300 causes the printer 23 to print and issue a pending receipt R5, an example of which is shown in FIG. The hold receipt R5 is an example of a hold slip, and includes the hold number e2 as the identification code, a barcode w that encodes the hold number e2, descriptions v1 to v3, and the POS terminal that issued the hold receipt R5. 2, register number f2, etc.

Explanation v1 indicates the reason why tax exemption cannot be applied, such as "The total amount of purchases has not reached the applicable amount." Explanation v2 indicates the current status, such as "Tax exemption application procedure has been put on hold." Explanation v3 provides guidance on the amount remaining until tax exemption is applied. The shortfall here is the amount obtained by subtracting the total amount from the lower limit of tax exemption application. In addition, in implementation, it is sufficient that at least the above-mentioned suspension number is printed on the suspension receipt R5 in the form of characters or a code image that can be read by a scanner.

After completing the hold process, the control unit 300 ends the post-settlement tax exemption application process (step S32) and returns to step S11.

Pending receipt R5 is used when the customer who received the receipt R5 makes a purchase (additional purchase) for an amount equal to or more than the shortfall and requests tax exemption application processing after payment (in other words, restarts tax exemption application processing after payment). It is used in When restarting this process, the control unit 300 functions as a restarting means 325 in addition to the specifying means 321 in the transaction designation (step S81). The control unit 300 serving as the specifying means 321 here causes the scanner 24 to read the barcode w displayed on the receipt R0 of the additional purchase.

By reading the pending receipt R5, the control unit 300 as the resuming unit 325 reads the record identified by the pending number e2 indicated by the pending receipt R5 from the pending history DB2, and reads the record identified by the pending receipt R5 at the time of issuance of the pending receipt R5 recorded in each record. Each transaction to be processed is read from the transaction history DB1. This eliminates the need to reread the receipt R0 for each transaction to be processed when issuing the pending receipt R5.

Next, the additional processing (step S86) will be explained. When the add button B74 is operated on the confirmation screen G7 in the state shown in FIG. 28, the control unit 300 performs additional processing. In the additional processing, the control unit 300 accepts additional purchases on the spot. In other words, when the operator informs the customer of the shortage amount and the customer presents the product to purchase additionally on the spot, the POS terminal 2 accepts the registration of sales data for that product, and then adds the price of the product to the total amount. do.

FIG. 30 is a diagram showing an example of the confirmation screen G7 in a state in which one of the two types of shortfall has been compensated by the additional processing. At this time, a message M2 is displayed on the confirmation screen G7. Message M2 informs of the shortfall amount that has been changed due to additional purchases. Furthermore, when displaying this confirmation screen G7, the control unit 300 changes the confirm button B71 to a usable state.

As described above, according to the embodiment, for one or more transactions designated as processing targets after transaction processing, tax exemption processing can be performed for tax exempt products included in the transactions, so that tax exemption processing can be performed for tax exempt products included in the transactions. Even in cases where tax exemption procedures are carried out, tax exemption processing can be executed without canceling the transaction.

Returning to the explanation of FIG. If it is determined in step S31 that the post-settlement tax exemption application key K3 has not been operated (No in step S31), the control unit 300 determines whether the register minus key K4 has been operated (step S41). If it is determined that the tax exemption application key K3 has been operated (Step S41: Yes), the control unit 300 subsequently determines whether the post-settlement tax exemption application key K3 has been operated (Step S42). If it is determined that the operation has been performed (Yes in step S42), the control unit 300 executes post-settlement tax exemption application cancellation processing (step S43).

Post-settlement tax exemption processing can only be applied once in a series of transactions. Therefore, if there is a mistake in the product to which tax exemption was applied after payment, or if there is a new product that you would like to apply tax exemption to, if you wish to apply tax exemption after payment again, please apply the tax exemption after payment that has already been applied. Canceling the tax exemption application process It is necessary to perform the post-settlement tax exemption application cancellation process and then apply the post-settlement tax exemption application again. We omit the details of the post-payment tax exemption application cancellation process.

If it is determined in step S42 that the post-settlement tax exemption application key K3 has not been operated (No in step S42), the control unit 300 may, for example, The cancellation process is executed (step S44). Details of the cancellation process will be omitted.

After the process of step S12, after the process of step S16, after the process of step S22, after the process of step S32, after the process of step S43, and after the process of step S44, the control unit 300 returns to step S11. Further, if it is determined in step S41 that the register minus key K4 is not operated (No in step S41), the control unit 300 returns to step S11.

As described above, according to the embodiment, the post-settlement tax exemption application cancellation process can be executed for one or more transactions specified as processing targets without canceling the transaction to which the post-settlement tax exemption has been applied.

Although several embodiments of the present invention have been described above, these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, substitutions, and changes can be made without departing from the gist of the invention. These embodiments and their modifications are included within the scope and gist of the invention, as well as within the scope of the invention described in the claims and its equivalents.

For example, in the embodiment, information held in a passport is read as a character string by using the optical character recognition function of the passport reader 25, but the reading method is not limited to this. Specifically, if a storage medium such as an IC tag is embedded in the passport, an RFID reader may be used as the passport reader 25 to read information corresponding to the recorded items from the storage medium.

Further, in the embodiment, when inputting a transaction number, the barcode printed on the receipt is read and input, but the invention is not limited to this. For example, the operator inputs the transaction number printed on the receipt from the keyboard 21. You may also do so. In this case, the receipt may not have a barcode printed on it.

Further, in the embodiment, the transaction history DB 1 is provided in the server 4, but it may be provided in other places such as the POS terminal 2, for example.

Further, in the embodiment, a product is described as an example of a sales target, but a sales target other than a product (for example, a service) may be used.

Further, in the embodiment, the server 4 has been described as an example of an information processing device, but the information processing device is not limited to this, and may be, for example, a personal computer installed at a service counter or the like.
