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 goods, services, etc. to non-residents such as foreign tourists, taxes such as consumption tax related to the sales object have to be paid. There is a so-called tax exemption system that exempts Tax exemption applies to products purchased by the same non-resident at the same store on the same day. To be eligible for tax exemption, the total amount of general goods and/or consumables must be 5,000 yen or more.

Transactions related to tax exemption are performed in a sales data processing device such as a POS terminal equipped with a tax exemption electronic function, and transaction data indicating details of the transaction is held in the sales data processing device. In addition, the sales data processing device also allows cancellation of transactions and return of products, and cancellation processing such as deletion of transaction data and cash register minus is performed depending on the processing contents.

Furthermore, some duty-free shops are equipped with a plurality of sales data processing devices. In this case, each of the sales data processing devices locally stores transaction data of tax exemption transactions performed by the sales data processing device of its own device, and also stores it in a server connected to the network. . In such a configuration, when each sales data processing device performs a transaction related to tax exemption, based on the total amount of the transaction and the total amount of other transactions related to the same non-resident stored in the server, It is possible to determine whether the transaction satisfies the tax exemption conditions.

By the way, if a transaction related to tax exemption is canceled or a product is returned, the total amount will also change. For example, among multiple transactions conducted by the same non-resident using different sales data processing devices at the same store, if one transaction is canceled and the total amount is less than 5,000 yen, the other transactions will not be eligible for tax exemption. It turns out.

In this case, the operator needs to perform operations such as removing the transaction data of other transactions that fall outside the tax exemption conditions from tax exemption, but the sales data processing device that performs the cancellation process cannot be easily checked, and there is room for further improvement in terms of convenience.

For example, if the transaction data of another transaction stored in another sales data processing device falls outside of the tax exemption conditions due to cancellation processing performed by the sales data processing device, the operator will be required to manipulate that transaction data. It may not be possible to easily confirm transactions that fall outside of the tax exemption conditions, which may result in a delay in response. Therefore, there is a possibility that a difference may occur in the transaction details between the transaction data stored in the sales data processing device and the transaction data stored in the server.

The problem to be solved by the present invention is to provide a sales data processing device and a program that can easily confirm transactions that fall outside of tax exemption conditions.

The sales data processing device of the embodiment includes transaction data indicating a breakdown of tax-free transactions performed in each of the plurality of sales data processing devices, transaction identification information that can identify the tax-free transaction, and identification of the user who performed the tax-free transaction. A sales data processing device connected via a network to a server device that stores possible user identification information in association with the user identification information; a second acquisition means for acquiring possible user identification information; a tax exemption declaration means for declaring a tax-free transaction; and the product acquired by the first acquisition means when the tax exemption declaration means declares a tax-free transaction. The tax-free transaction is based on the total amount of products corresponding to each piece of identification information and the total amount of other tax-free transactions related to the user identification information acquired by the second acquisition means, which is stored in the server device. a determination means for determining whether the conditions of the tax exemption system for exempting the tax are met; and a determination means for determining whether the conditions for the tax exemption system are met; a payment means that executes the payment process for the product corresponding to each of the above, transaction data of the tax-free transaction settled by the payment means, transaction identification information of the tax-free transaction, and the user identification acquired by the second acquisition means. a storage means for storing information in the server device in association with the information; and receiving an instruction to cancel the tax-free transaction or a product settled for the tax-free transaction, and performs a cancellation process on the transaction data to be processed in accordance with the cancellation instruction. and a first output control for outputting information regarding another tax-exempt transaction that deviates from the conditions of the tax-exemption system when the server device has another tax-exempt transaction that deviates from the conditions of the tax exemption system due to the cancellation process executed by the canceling unit. and means.

FIG. 3 is a diagram showing an example of the data structure of the tax exemption classification file 481. As shown in FIG. 3, the tax exemption classification file 481 has data items of a tax exemption classification code and a tax exemption classification name. Data indicating "general goods," "consumables," and "not subject to tax exemption" is set in the tax exemption classification name. Here, "consumables" is data indicating the classification of tax-exempt items related to consumables such as foods, beverages, medicines, and cosmetics. "General goods" is data indicating the classification of tax-exempt goods used for everyday life other than consumables. “Not eligible for tax exemption” is data indicating the classification of items that are not eligible for tax exemption. In the example of FIG. 3, the tax exemption category code corresponding to "general goods" is set to "01". “02” is set as the tax exemption classification code corresponding to “consumables”. “03” is set as the tax exemption category code corresponding to “not eligible for tax exemption”.

FIG. 4 is a diagram showing an example of the data structure of the tax exemption condition file 482. As shown in FIG. 4, the tax exemption condition file 482 has data items of tax exemption category codes and tax exemption conditions. The tax exemption conditions are the conditions for a tax exempt item to actually be treated as tax exempt.

In the example shown in FIG. 4, the tax exemption condition for the tax exemption category code "01", that is, the tax exemption condition for general goods, is that the total amount (excluding tax) in one day at the same store is 5000 yen or more. Further, the tax exemption conditions for the tax exemption classification code "02", that is, the tax exemption conditions for consumables, are such that the total amount (excluding tax) in one day at the same store is 5,000 yen or more and 500,000 yen or less. In addition, even if the amount of each of the general goods and consumables is less than 5,000 yen, if the total amount is 5,000 yen or more, the general goods can be treated as consumables and the tax exemption classification code "02" It shall be stipulated that the tax exemption conditions shall apply.

FIG. 5 is a diagram showing an example of the data structure of the tax-free transaction management file 483. As shown in FIG. 5, the tax exemption transaction management file 483 has data items such as a cash register number, user ID, transaction number, transaction details, and tax exemption flag.

The cash register number is an example of device identification information that can identify the POS terminal 2 that made the transaction. In this embodiment, it is assumed that each POS terminal 2 is assigned a unique cash register number in advance. Note that the identification information of the POS terminal 2 is not limited to this, and may be, for example, a serial number or an IP address.

The user ID is an example of user identification information that can identify the user who made the transaction. The user ID is a passport number, name, etc. written on a passport owned by a non-resident who is a user.

The transaction number is an example of transaction identification information that can identify each transaction performed at the POS terminal 2 corresponding to the cash register number. The transaction number is issued, for example, by the POS terminal 2 that performs the transaction. In this embodiment, the transaction number is a unique number that does not overlap in each POS terminal 2, but the transaction number is not limited to this, and may be a unique number that does not overlap among POS terminals 2 having the same cash register number.

The transaction details include information indicating the details of the products purchased in the transaction specified by the transaction number. For example, the transaction details include product information (product code, product name, price, tax exemption category code, etc.) of the product the user purchases, payment information (total amount, deposit amount, change amount, etc.), etc. Contains date and time information indicating the date and time when the data was sent. The tax exemption flag is binary information for identifying whether the transaction corresponding to the transaction number satisfies the tax exemption conditions. The tax exemption flag is set to be valid (for example, "1") when the tax exemption conditions are met, and is set to invalid (for example, "0") when the tax exemption conditions are not met.

Hereinafter, the set of the register number, user ID, transaction number, transaction details, and tax exemption flag will also be referred to as "tax exemption transaction data." In addition, the set of tax-exempt transaction data remaining after excluding the cash register number and user ID is also referred to as "transaction data."

The control unit 400 of the server device 4 determines whether the transaction performed at the POS terminal 2 satisfies the tax exemption conditions based on the tax exemption condition file 482, and returns the determination result to the POS terminal 2. In addition, the control unit 400 of the server device 4 stores transaction data of tax-free transactions (hereinafter also referred to as tax-free transactions or simply transactions) performed at each of the POS terminals 2 in the tax-free transaction management file 483 as tax-free transaction data. Remember and manage. Note that in this embodiment, a tax-free transaction means a transaction in which a tax-free declaration key 211, which will be described later, is input, regardless of whether tax-free conditions are satisfied.

Next, the POS terminal 2 will be explained. The POS terminal 2 is assigned a unique register number and placed at the payment location. When the operator operates the POS terminal 2, the POS terminal 2 executes registration processing and payment processing for products to be sold.

The registration process optically reads code symbols such as barcodes attached to products to be sold, combines them into a product code, displays product information such as the product name and price of the product code, and also displays the product code. This refers to the process of storing the product information included in the RAM 33 or the like. The payment process includes displaying the total amount based on the product information stored in the RAM 33 etc. during the registration process, calculating and displaying change based on the deposit deposited by the customer, and discharging the change to the change machine. Refers to the process of giving instructions, the process of issuing a receipt with product information and payment information printed, etc.

FIG. 6 is a diagram showing an example of the hardware configuration of the POS terminal 2. As shown in FIG. As shown in FIG. 6, the POS terminal 2 includes a control unit 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 RAM 33 is formed with, for example, a registration table T that stores product information of product codes read from products. The CPU 31, ROM 32, and RAM 33 are connected via a bus 34.

The control unit 300 is connected to a keyboard 21, a display unit 22, a printer 23, a card reader/writer (R/W) 24, a scanner 25, a passport reader 27, etc. via a bus 34 and a controller 35.

The keyboard 21 has various keys arranged in blocks. Various keys include, for example, a number key for inputting product codes, amounts, etc., a PLU key for specifying various products, a confirmation key for confirming number input using the number keys, a clear key, etc. It is. The keyboard 21 also includes a tax exemption declaration key 211, a subtotal key 212, a close key 213, and a cancel key 214.

The tax exemption declaration key 211 is a key for declaring tax exempt transactions. The subtotal key 212 is a key for declaring the calculation of the total amount. The closing key 213 is a key for declaring closing with cash in sales processing. The cancellation key 214 is a key for canceling a registered product or declaring cancellation of a transaction.

The display unit 22 is a liquid crystal display device with a touch panel provided on the display surface.
The scanner 25 is a device that optically reads code symbols such as barcodes and two-dimensional codes attached to products.

The passport reader 27 is a reader device that reads information held in a passport. For example, the passport reader 27 has an optical character recognition (OCR) function that optically reads a character string such as a passport number written on a passport.

Further, a memory unit 26, which is a storage device, is connected to the control unit 300 via a bus 34. The memory unit 26 is composed of an HDD (Hard Disc Drive), a flash memory, etc., and retains the stored contents even if the power is cut off. The memory unit 26 stores various programs executable by the CPU 31 and setting information. The memory unit 26 also stores data files such as a product master file 261 and a transaction management file 262.

FIG. 7 is a diagram showing an example of the data structure of the product master file 261. As shown in FIG. 7, the product master file 261 has data items such as a product code, product name, price, and tax exemption classification code. Here, the product code is an example of product identification information that can identify each product. The product code is associated with data such as the product name, price, tax exemption category code, etc. as product information indicating the type and attributes of the product. The product name indicates the name of the product corresponding to the product code. The price indicates the tax-excluded price of the product corresponding to the product code. The tax exemption category code corresponds to the tax exemption category code explained in FIG. 3, and indicates whether the product corresponding to the product code belongs to general goods, consumables, or non-tax exempt items.

FIG. 8 is a diagram showing an example of the data structure of the transaction management file 262. As shown in FIG. 8, the transaction management file 262 has data items such as a transaction number, transaction details, tax exemption flag, and tax exemption declaration key flag. Here, the set of transaction number, transaction details, and tax exemption flag corresponds to transaction data.

The transaction number is an example of transaction identification information that can identify each transaction performed at the own POS terminal 2. The transaction details include product information showing details of the products purchased in the transaction corresponding to the transaction number, payment information, and the like. The tax exemption flag is binary information for identifying whether the transaction corresponding to the transaction number satisfies the tax exemption conditions.

The tax exemption declaration key flag is binary information for identifying whether the tax exemption declaration key flag has been input. The tax exemption declaration key flag is set to be valid (for example, "1") when the tax exemption declaration key flag is input, and is set to invalid (for example, "0") when the tax exemption declaration key flag is input. That is, in a transaction that satisfies the tax exemption conditions, the tax exemption flag and the tax exemption declaration key flag are set to be valid. Furthermore, for transactions that do not satisfy the tax exemption conditions even though the tax exemption declaration key has been input, the tax exemption flag is set to invalid and the tax exemption declaration key flag is set to valid. Further, in the case of a normal transaction, the tax exemption flag and the tax exemption declaration key flag are set to be invalid.

In the case of a tax-free transaction, the POS terminal 2 acquires a user ID from the user's passport, but the acquired user ID may be stored in the transaction management file 262 in association with the corresponding transaction number.

Returning to FIG. 6, a communication interface (I/F) 28 is further connected to the control unit 300 via a bus 34. The communication interface 28 performs data communication with the server device 4, which is a host device, via the network 3.

With the above configuration, the control unit 300 executes the program stored in the memory unit 26 to control the keyboard 21, display unit 22, printer 23, card reader/writer 24, scanner 25, memory unit 26, passport reader 27, It controls each part such as the communication I/F 28 and performs predetermined processing.

Next, the functional configurations of the POS terminal 2 and the server device 4 will be explained. FIG. 9 is a diagram showing an example of the functional configuration of the POS terminal 2 and the server device 4. As shown in FIG.

As shown in FIG. 9, the POS terminal 2 includes a registration section 301, a tax exemption processing section 302, a payment processing section 303, a cancellation processing section 304, a display output section 305, and a print output section 306.

A part or all of the functional configuration of the POS terminal 2 is a software configuration realized by cooperation between the processor of the POS terminal 2 (e.g., CPU 31) and the program stored in the memory (e.g., ROM 32, memory unit 26). You can. Further, part or all of the functional configuration provided in the POS terminal 2 may be a hardware configuration realized by a dedicated circuit installed in the POS terminal 2.

The registration unit 301 is an example of a first acquisition unit. The registration unit 301 registers product codes, product information, etc. of products to be sold. Specifically, the registration unit 301 drives the scanner 25 via the controller 35 and acquires the product code read by the scanner 25. Further, the registration unit 301 obtains product information from the product master file 261 based on the product code, and registers the obtained product information in the registration table T of the RAM 33.

The tax exemption processing unit 302 is an example of a second acquisition means, a tax exemption declaration means, and a determination means. The tax exemption processing unit 302 declares a tax exemption transaction in response to input from the tax exemption declaration key 211, and performs processing related to tax exemption. Specifically, the tax exemption processing unit 302 drives the passport reader 27 via the controller 35 and acquires a user ID such as a passport number read by the passport reader 27. In addition, the tax exemption processing unit 302 transmits a condition determination request including the user ID and information based on the product information registered in the registration table T to the server device 4, and determines the determination result of whether or not the tax exemption condition is satisfied. is acquired from the server device 4. Based on the determination result obtained from the server device 4, the tax exemption processing unit 302 determines whether the tax exemption transaction performed at the POS terminal 2 of the own device satisfies the tax exemption conditions.

When the tax exemption conditions are met, the tax exemption processing unit 302 cooperates with the payment processing unit 303 to execute payment processing (hereinafter also referred to as tax exemption processing) using a tax-exempt price that is exempt from consumption tax and the like. Specifically, the tax exemption processing unit 302 performs tax exemption processing on product information whose tax exemption classification code is “01” or “02” and which is determined to meet the tax exemption conditions among the product information registered in the registration table T. Execute. Further, if the tax exemption condition is not satisfied, the tax exemption processing unit 302 causes the payment process to be performed at a tax-inclusive price including consumption tax and the like.

Note that the tax exemption processing unit 302 may transmit product information whose tax exemption classification codes are "01" and "02" among the product information registered in the registration table T as a condition determination request. In addition, the tax exemption processing unit 302 calculates the total amount of products for general goods and consumables based on the product information with tax exemption classification codes "01" and "02" among the product information registered in the registration table T. The total amount may be sent as a condition determination request.

The payment processing unit 303 is an example of a payment means and a storage means. The payment processing unit 303 performs payment processing for the product based on the product information registered in the registration table T in response to the input of the closing key 213. Furthermore, upon completion of the payment process, the payment processing unit 303 stores transaction data of the transaction related to the payment process in the transaction management file 262.

Further, the payment processing unit 303 cooperates with the tax exemption processing unit 302 to perform payment processing (tax exemption processing) at a tax-exempt price that is exempt from consumption tax and the like. In this case, the payment processing unit 303 stores transaction data in which the tax exemption flag and the tax exemption declaration key flag are set to valid in the transaction management file 262. In addition, even if the tax exemption declaration key 211 is input, the payment processing unit 303 disables the tax exemption flag and enables the tax exemption declaration key flag when the payment process is performed at a tax-included price. Transaction data is stored in transaction management file 262. Note that when the payment processing unit 303 performs the payment processing as a normal transaction, the payment processing unit 303 stores transaction data in which the tax exemption flag and the tax exemption declaration key flag are set to invalid in the transaction management file 262.

In addition, when the tax exemption declaration key flag is set to valid, the payment processing unit 303 stores the transaction data of the transaction in the server device 4. The information is sent to the server device 4 together with the user ID of the user who made the request.

The cancellation processing unit 304 is an example of a cancellation unit and a first output control unit. When the cancellation key 214 is input, the cancellation processing unit 304 executes cancellation processing such as canceling a transaction or returning a product in response to a separately input operation instructing cancellation details. Specifically, when the transaction number related to the transaction to be processed is input, the cancellation processing unit 304 identifies transaction data corresponding to the transaction number from the transaction management file 262. Next, the cancellation processing unit 304 executes cancellation processing according to the cancellation details based on the specified transaction data. For example, when canceling the transaction itself, the cancellation processing unit 304 deletes the transaction data to be processed from the transaction management file 262 or moves it to another management file. Further, for example, when canceling (returning) a product, the cancellation processing unit 304 executes a cash register minus process to delete the product code of the product to be canceled from the transaction data to be processed.

Further, when the transaction data specified from the transaction management file 262 is a tax-free transaction, the cancellation processing unit 304 transmits a condition determination request including the transaction number of the transaction data and cancellation details to the server device 4. Then, the cancellation processing unit 304 obtains the determination result as to whether the tax exemption condition is satisfied after the cancellation process from the server device 4, and determines whether the tax exemption condition is satisfied after the cancellation process based on the determination result. .

For example, when canceling the transaction itself, the cancellation processing unit 304 transmits to the server device 4 a condition determination request specifying the transaction number to be canceled and cancellation of the transaction. For example, when performing return processing for a specific product purchased in a specific transaction, the cancellation processing unit 304 includes the transaction number of the transaction, the product code or product information of the product to be returned, and the cancellation information of the product. A condition determination request with instructions is sent to the server device 4.

Here, if the tax exemption condition still holds after the cancellation process, the cancellation processing unit 304 executes the cancellation process on the specified transaction data. Then, the cancellation processing unit 304 transmits instruction information instructing execution of the cancellation contents to the server device 4.

Further, if the tax exemption condition is not satisfied after the cancellation process, the cancellation processing unit 304 causes the display unit 22 to display a confirmation screen notifying that the tax exemption condition is not satisfied. After displaying the confirmation screen, if execution of the cancellation process is instructed, the cancellation process is executed based on the specified transaction data.

Further, the cancellation processing unit 304 determines whether or not there is another transaction that falls outside the tax exemption condition due to the failure of the tax exemption condition, and if there is, displays and outputs information regarding the other transaction that falls outside the tax exemption condition. The information is outputted via the section 305 and the printout section 306. Here, information regarding other transactions is information that can identify other transactions that are outside the tax exemption conditions, such as the transaction number of the relevant transaction, the cash register number of the POS terminal 2 that conducted the transaction, and the total amount of the transaction. It is preferable. In the present embodiment, the cancellation processing unit 304 determines whether there are other transactions that fall outside of the tax exemption conditions, based on information regarding other transactions that is transmitted from the server device 4 together with the determination result that the tax exemption conditions are not satisfied. judge.

The display output unit 305 controls the display output of the display unit 22. For example, the display output unit 305 causes the display unit 22 to display an operation screen for supporting the operation of the POS terminal 2. Further, the display output unit 305 causes the display unit 22 to display information regarding each registered product based on the data registered in the registration table T. In addition, the display output unit 305 cooperates with the tax exemption processing unit 302 to cause the display unit 22 to display the determination result of the tax exemption conditions and to display information regarding transactions that do not meet the tax exemption conditions on the display unit 22. .

The print output unit 306 controls the print output of the printer 23. For example, the print output unit 306 cooperates with the payment processing unit 303 to output information indicating transaction details to the printer 23 and instruct the printer 23 to issue a receipt. In addition, the print output unit 306 cooperates with the tax exemption processing unit 302 to output information regarding transactions that do not meet the tax exemption conditions to the printer 23 and instruct the printer 23 to issue a receipt. In the following, in order to distinguish it from a receipt for a customer on which transaction details are printed, a receipt on which information on a transaction outside the tax exemption conditions is printed is also referred to as a "receipt for a clerk."

On the other hand, the server device 4 includes a tax exemption condition determination section 401 and a data management section 402.

Part or all of the functional configuration provided by the server device 4 may be a software configuration realized by cooperation between the processor of the server device 4 (e.g., CPU 41) and the program stored in the memory (e.g., ROM 42, HDD 48). good. Further, a part or all of the functional configuration provided in the server device 4 may be a hardware configuration realized by a dedicated circuit installed in the server device 4 or the like.

Based on the tax exemption condition file 482, the tax exemption condition determination unit 401 determines whether the tax exemption transaction performed at each POS terminal 2 satisfies the tax exemption condition. Specifically, in response to a condition determination request transmitted from the POS terminal 2, the tax exemption condition determination unit 401 determines whether the details of the transaction indicated in the condition determination request satisfy the tax exemption conditions, and The determination result is returned to the POS terminal 2.

For example, if the condition determination request includes product information, the tax exemption condition determination unit 401 calculates the total amount of products with tax exemption classification codes “01” and “02” included in the product information, and determines whether the total amount is It is determined whether the tax exemption conditions of the tax exemption condition file 482 are satisfied. Furthermore, based on the user ID included in the condition determination request, the tax exemption condition determination unit 401 searches the tax exemption transaction management file 483 for tax exemption transaction data that includes the user ID. Then, the tax exemption condition determination unit 401 determines whether the sum of the total amount of the searched tax exemption transaction data and the total amount of product information included in the condition determination request satisfies the tax exemption conditions of the tax exemption condition file 482. do. Note that the tax exemption condition determination unit 401 searches for tax exemption transaction data with a transaction date and time on the same day as the date on which the condition determination request is received.

If the tax exemption condition determination unit 401 determines that the tax exemption condition is satisfied, it transmits information notifying that the tax exemption condition is satisfied to the POS terminal 2. Further, if it is determined that the tax exemption conditions are not satisfied, the tax exemption condition determining unit 401 transmits information notifying that the tax exemption conditions are not satisfied to the POS terminal 2.

For example, if the condition determination request includes cancellation details, the tax exemption condition determination unit 401 determines that the total amount is determined in the tax exemption condition file 482 based on the total amount after subtracting the amount of the transaction or product specified in the cancellation contents. Determine whether the tax exemption conditions are met.

Specifically, when the tax exemption condition determination unit 401 identifies the tax exempt transaction data corresponding to the transaction number specified in the cancellation details from the tax exempt transaction management file 483, the tax exemption condition determination unit 401 determines the total amount after cancellation processing based on the tax exempt transaction data. Calculate. For example, when canceling the transaction itself, the tax exemption condition determination unit 401 sets the total amount of the specified tax exemption transaction data to zero. Further, for example, when canceling a specific product, the tax exemption condition determining unit 401 calculates the total amount by subtracting the price of the product to be canceled.

Furthermore, based on the user ID included in the specified tax-free transaction data, the tax-exemption condition determination unit 401 searches for other tax-free transaction data that includes the user ID. Then, the tax exemption condition determining unit 401 determines whether the sum of the total amount of the tax exempt transaction data after the cancellation process and the total amount of other retrieved tax exempt transaction data satisfies the tax exemption condition of the tax exemption condition file 482. do.

Here, if the tax exemption condition determining unit 401 determines that the tax exemption condition is satisfied, it transmits information notifying that the tax exemption condition is satisfied to the POS terminal 2. Further, if it is determined that the tax exemption conditions are not satisfied, the tax exemption condition determining unit 401 transmits information notifying that the tax exemption conditions are not satisfied to the POS terminal 2. In addition, if there is other tax-exempt transaction data for which the tax-exempt condition has not been met due to cancellation processing, the tax-exempt condition determination unit 401 determines information such as the cash register number, transaction number, and total amount included in the other tax-exempt transaction data. is sent to the POS terminal 2 along with information notifying that the tax exemption conditions are not satisfied.

The data management unit 402 performs data management of the tax-free transaction management file 483. For example, the data management unit 402 stores transaction data transmitted from the POS terminal 2 in the tax-free transaction management file 483. Specifically, when a set of a register number, a user ID, and transaction data is transmitted from the POS terminal 2, the data management unit 402 stores the set as tax-free transaction data in the tax-free transaction management file 483.

Further, the data management unit 402 executes a cancellation process on the tax-free transaction data to be processed in response to a cancellation instruction transmitted from the POS terminal 2. For example, when receiving an instruction to cancel a transaction specifying a transaction number, the data management unit 402 deletes the tax-free transaction data of the corresponding transaction number from the tax-free transaction management file 483 or moves it to another management file. . Further, for example, when receiving an instruction to cancel a product specifying a transaction number and a product code, the data management unit 402 performs a register minus process to delete the product code of the specified product from the tax-free transaction data of the corresponding transaction number. Execute. If there is tax-free transaction data for which the tax-free conditions are not met due to cancellation processing, the data management unit 402 cooperates with the tax-free condition determination unit 401 to delete the tax-free transactions for which the tax-free conditions are not met. Disable tax exemption flag for data.

Next, an example of the operation of the POS terminal 2 and the server device 4 will be described using FIGS. 10 and 11.

FIG. 10 is a diagram schematically showing an example of a transaction using the POS system 1. First, as shown in FIG. 10(a), assume that a transaction with transaction number "0001" is performed at POS terminal 2 with cash register number "01". In this transaction, the user purchases products (general products or consumables) for a total amount of 5,000 yen. Here, if the tax exemption declaration key 211 is input during a transaction and a user ID is acquired, the tax exemption processing unit 302 of the POS terminal 2 with the register number "01" A condition determination request including the ID etc. is transmitted to the server device 4. In this case, the total amount of product information included in the condition determination request is 5,000 yen or more, which satisfies the tax exemption conditions of the tax exemption condition file 482. Therefore, the tax exemption condition determination unit 401 of the server device 4 determines that the tax exemption condition is satisfied, and transmits the determination result to the POS terminal 2 with the cashier number "01".

When the POS terminal 2 with the cashier number "01" receives the determination result from the server device 4, the tax exemption processing unit 302 cooperates with the payment processing unit 303 to complete tax exemption processing for 5000 yen. Then, the payment processing unit 303 of the POS terminal 2 with the cashier number "01" transmits the transaction data of the transaction to the server device 4 along with the cashier number "01" of the own machine and the user ID of the user who made the transaction. The data management unit 402 of the server device 4 stores transaction data and the like transmitted from the POS terminal 2 with the register number "01" as tax-free transaction data in the tax-free transaction management file 483.

Next, in FIG. 10(b), it is assumed that the same user as in FIG. 10(a) performs a transaction with transaction number "0006" at the POS terminal 2 with cashier number "02". In this transaction, the user purchases products (general products or consumables) for a total amount of 100 yen. Here, if the tax exemption declaration key 211 is input during a transaction and a user ID is acquired, the tax exemption processing unit 302 of the POS terminal 2 with the register number "02" A condition determination request including the ID etc. is transmitted to the server device 4. In this case, the total amount of the tax-exempt transaction data related to the transaction in FIG. It turns out. Therefore, the tax exemption condition determination unit 401 of the server device 4 determines that the tax exemption condition is met, and transmits the determination result to the POS terminal 2 with the cashier number "02".

When the POS terminal 2 with the cash register number "02" receives the determination result from the server device 4, the tax exemption processing section 302 cooperates with the payment processing section 303 to establish tax exemption processing for 100 yen. Then, the payment processing unit 303 of the POS terminal 2 with the cash register number "02" transmits the transaction data of the transaction to the server device 4, along with the cash register number "02" of the terminal itself and the user ID of the user who made the transaction. The data management unit 402 of the server device 4 stores transaction data and the like transmitted from the POS terminal 2 with the register number "02" as tax-free transaction data in the tax-free transaction management file 483.

Subsequently, in FIG. 10(c), it is assumed that the same user as in the transactions in FIGS. 10(a) and 10(b) performs a transaction with transaction number "0015" at the POS terminal 2 with cashier number "03". In this transaction, the user purchases products (general products or consumables) for a total amount of 200 yen. Here, if the tax exemption declaration key 211 is input during a transaction and a user ID is acquired, the tax exemption processing unit 302 of the POS terminal 2 with the register number "03" A condition determination request including the ID etc. is transmitted to the server device 4. In this case, the total amount of the tax-exempt transaction data related to the transactions in FIGS. This will satisfy the tax exemption conditions. Therefore, the tax exemption condition determination unit 401 of the server device 4 determines that the tax exemption condition is satisfied, and transmits the determination result to the POS terminal 2 with the cashier number "03".

In the POS terminal 2 with the cash register number "03" which has received the determination result from the server device 4, the tax exemption processing section 302 cooperates with the payment processing section 303 to complete the tax exemption processing for 200 yen. Then, the payment processing unit 303 of the POS terminal 2 with the cashier number "03" transmits the transaction data of the transaction to the server device 4, along with the cashier number "03" of the own machine and the user ID of the user who made the transaction. The data management unit 402 of the server device 4 stores transaction data and the like transmitted from the POS terminal 2 with the register number "03" as tax-free transaction data in the tax-free transaction management file 483.

Subsequently, in FIG. 10(d), the same user as in the transaction in FIGS. 10(a) to (c) executes the transaction in FIG. 10(a) (transaction number "0001") at the POS terminal 2 with the register number "01". ). Suppose you return a product you purchased. In this case, the operator of the POS terminal 2 with the register number "01" inputs the cancellation key 214, and then inputs the transaction number of the transaction to be canceled written on the customer receipt or the like.

The cancellation processing unit of the POS terminal 2 with the register number "01" transmits to the server device 4 the input transaction number and a condition determination request instructing to cancel the transaction with the transaction number. In this case, the total amount of tax-free transaction data related to the transactions in Figure 10(a), "5,000 yen," is subtracted from the total amount of tax-free transaction data, "5,300 yen" related to each transaction in Figures 10(a) to (c). The resulting value is “300 yen”, which does not satisfy the tax exemption conditions of the tax exemption condition file 482. Therefore, the tax exemption condition determination unit 401 of the server device 4 determines that the tax exemption condition is not satisfied, and transmits the determination result to the POS terminal 2 with the cashier number "03".

Furthermore, in this case, since the transactions shown in FIGS. 10(b) and 10(c) are outside the tax exemption conditions, the tax exemption condition determining unit 401 of the server device 4 uses the transaction data related to the transactions shown in FIGS. The transaction number, cashier number, total amount, etc. are read out and sent along with the determination result to the POS terminal 2 with the cashier number "01".

In the POS terminal 2 with the register number "01", upon receiving the determination result from the server device 4, the cancellation processing unit 304 displays the content of the determination result on the display unit 22. For example, if the determination result indicates that the tax exemption conditions are not met, the cancellation processing unit 304 causes the display unit 22 to display a screen for confirming whether to continue the cancellation process. When instructed to continue the cancellation process, the cancellation processing unit 304 executes the cancellation process by deleting the transaction data of the corresponding transaction stored in the transaction management file 262. In addition, the operator will refund to the user the amount after deducting the tax for the transactions shown in Figures 10(b) and 10(c), which are outside the tax exemption conditions, from the amount of "5,000 yen" of the returned product. holds true.

Further, when the cancellation processing unit 304 executes the cancellation processing, it transmits a cancellation instruction to the server device 4 that specifies the transaction number to be processed and the details of the cancellation. Upon receiving the cancellation instruction, the data management unit 402 of the server device 4 executes cancellation processing by deleting the corresponding transaction data based on the instructed content. In addition, along with the cancellation process, the data management unit 402 of the server device 4 disables the tax exemption flag of the tax exemption transaction data that does not meet the tax exemption conditions. For example, if tax-free transaction data with transaction numbers "0006" and "0015" are outside the tax-free conditions, the tax-free flags associated with these tax-free transaction data are set to be invalid.

Furthermore, if there are other transactions that fall outside of the tax exemption conditions upon execution of the cancellation process, the cancellation processing unit 304 cooperates with the printout unit 306 to display information regarding other transactions that fall outside of the tax exemption conditions. Print it out as a receipt for the clerk. Specifically, in the example shown in FIG. 10, the cancellation processing unit 304 prints out the information regarding the transactions shown in FIGS. 10(b) and 10(c) as a receipt for the clerk.

FIG. 11 is a diagram showing an example of a sales clerk's receipt. As shown in FIG. 11, the clerk's receipt is printed with information regarding transactions that are outside the tax exemption conditions, such as the cash register number of the POS terminal 2 where the transaction occurred, the transaction number, and the transaction amount (total amount). be done. Such information can be printed based on information notified from the server device 4.

After confirming the clerk's receipt, the operator inputs the transaction number written on the clerk's receipt at the POS terminal 2 corresponding to the register number written on the clerk's receipt, and performs an operation to invalidate the tax exemption flag, for example. For example, in the case of the clerk's sheet of FIG. 11, the operator performs an operation to invalidate the tax exemption flag of the transaction data of transaction number "0006" at the POS terminal 2 of register number "02". Further, for example, the operator performs an operation to invalidate the tax exemption flag of the transaction data with the transaction number "0015" at the POS terminal 2 with the cashier number "03".

Thereby, the transaction data (tax-exempt transaction data) stored in the server device 4 can be matched with the transaction data stored in each of the POS terminals 2, and data matching can be achieved.

An example of processing performed by the POS terminal 2 will be described below with reference to FIGS. 12 and 13.

FIG. 12 is a flowchart showing an example of sales data processing performed by the POS terminal 2. First, the control unit 300 determines whether a product code specifying a product has been input (step S11). If a product code is input (step S11; Yes), the registration unit 301 acquires product information of the product corresponding to the input product code from the product master file 261 based on the input product code (step S12). . Next, the registration unit 301 registers the acquired product information in the registration table T, and returns the process to step S11.

If it is determined that the product code has not been input (step S11; No), the control unit 300 determines whether the tax exemption declaration key 211 has been input (step S13). If the tax exemption declaration key is input (step S13; Yes), the tax exemption processing unit 302 reads the user ID that identifies the user via the passport reader 27 (step S14). Next, the tax exemption processing unit 302 stores the read user ID in the RAM 33 or the like, and returns the process to step S11.

If it is determined that the tax exemption declaration key 211 has not been input (step S13; No), the control unit 300 determines whether execution of payment has been instructed by operating the closing key 213 or the like (step S15). Here, if execution of payment is not instructed (step S15; No), the control unit 300 returns the process to step S11.

If execution of payment is instructed (step S15; Yes), payment processing unit 303 determines whether tax exemption declaration key 211 has been input (step S16). For example, the payment processing unit 303 determines whether the tax exemption declaration key 211 has been input based on whether the user ID is stored in the RAM 33. Note that the input of the tax exemption declaration key 211 may be performed after the payment execution instruction is issued.

If the tax exemption declaration key 211 has not been input (step S16; No), the payment processing unit 303 executes payment processing for the product at the tax-included price based on the product information of the product registered in the registration table T (step S16; No). S17). Then, the payment processing unit 303 stores the transaction data of the transaction in the transaction management file 262 in association with the transaction number that identifies the transaction (step S18), and ends this process. Note that in step S18, the transaction data is stored with the tax exemption flag and tax exemption declaration key flag set to invalid.

On the other hand, if the tax exemption declaration key 211 has been input (step S16; Yes), the tax exemption processing unit 302 sends a condition determination request including the product information registered in the registration table T and the user ID held in the RAM 33 to the server. The information is transmitted to the device 4 (step S19).

When the server device 4 receives the condition determination request, the tax exemption condition determination unit 401 determines that the tax exemption condition is satisfied based on the total amount calculated based on the product information and the total amount of other transactions stored in association with the user ID. It is determined whether or not the request is made, and the determination result is transmitted to the POS terminal 2 that is the request source. Then, the tax exemption processing unit 302 determines whether the tax exemption condition is satisfied based on the determination result transmitted from the server device 4 (step S20).

If the tax exemption condition is not satisfied (step S20; No), the payment processing unit 303 executes payment processing for the product at the tax-included price based on the product information of the product registered in the registration table T (step S21). The payment processing unit 303 then proceeds to step S23 to store the transaction data of the transaction.

Further, if the tax exemption conditions are satisfied (step S20; Yes), the payment processing unit 303 cooperates with the tax exemption processing unit 302 and processes the payment for the product based on the product information of the product registered in the registration table T. is executed at the tax-excluding price (step S22), and the process moves to step S23.

In step S23, the payment processing unit 303 stores the transaction data of the transaction in the transaction management file 262 in association with the transaction number that identifies the transaction (step S23). In step S23, the transaction data processed in step S21 is stored with the tax exemption flag set to invalid and the tax exemption declaration key flag set to valid. Further, the transaction data subjected to the payment processing (tax exemption processing) in step S22 is stored with the tax exemption flag and the tax exemption declaration key flag set to valid.

Note that even if the tax exemption condition is not met, the transaction data (tax exempt transaction data) is sent to the server device 4 because the tax exemption condition may be met by adding it up with other transactions that the same user will perform in the future. This is because there is. As a result, no matter which POS terminal 2 a transaction is made in, by referring to the past tax-free transaction data stored in the server device 4, it can be compared with a transaction made in another POS terminal 2. It is possible to determine the suitability of tax exemption conditions based on the total amount.

FIG. 13 is a flowchart showing an example of cancellation processing performed by the POS terminal 2. First, the control unit 300 waits until the cancel key 214 is input (step S31; No). When the cancellation key 214 is input (step S31; Yes), the cancellation processing unit 304 waits until the transaction number of the transaction to be processed for cancellation is input (step S32; No). When the transaction number is input (step S32; Yes), the cancellation processing unit 304 determines whether transaction data corresponding to the input transaction number exists in the transaction management file 262 (step S33).

If there is no transaction data corresponding to the input transaction number (step S33; No), the cancellation processing unit 304 returns the process to step S31. That is, in this embodiment, it is possible to cancel a transaction at the POS terminal 2 where the transaction to be canceled has been performed. Note that if there is no transaction data corresponding to the transaction number, the cancellation processing unit 304 may output a display on the POS terminal 2 of its own device to notify that there is no transaction data to be canceled.

If transaction data corresponding to the input transaction number exists (step S33; Yes), the cancellation processing unit 304 determines whether the tax exemption declaration key flag associated with the transaction data is valid (step S34). If the tax exemption declaration key flag is invalid (step S34; No), the cancellation processing unit 304 determines that the transaction is a normal transaction, and executes cancellation processing on the transaction data to be processed according to the cancellation details input separately (step S34; No). S35), this process ends.

Further, if the tax exemption declaration key flag is valid (step S34; Yes), the cancellation processing unit 304 determines whether the tax exemption flag is valid (step S36).

Here, if the tax exemption flag is invalid (step S36; No), the cancellation processing unit 304 executes cancellation processing on the transaction data to be processed according to the cancellation details input separately (step S37). Next, the cancellation processing unit 304 sends a cancellation instruction including the transaction number, cancellation details, etc. in order to reflect the cancellation process executed in step S37 in the corresponding transaction data (tax-exempt transaction data) stored in the server device 4. The information is transmitted to the server device 4 (step S38), and the process ends.

Thereby, the data management unit 402 of the server device 4 executes the cancellation process of the instructed contents on the target tax-free transaction data (transaction data) in response to the cancellation instruction transmitted from the POS terminal 2.

On the other hand, if the tax exemption flag is valid (step S36; Yes), the cancellation processing unit 304 transmits a condition determination request including the transaction number, cancellation details, etc. to the server device 4 (step S39). When the server device 4 receives the condition determination request, the tax exemption condition determination unit 401 determines whether or not the transaction will be canceled based on the transaction data of the transaction corresponding to the specified transaction number when the cancellation process specified in the cancellation details is performed. Calculate the total amount. In addition, the tax exemption condition determination unit 401 adds up the calculated total amount and the total amount of other transactions including the user ID corresponding to the specified transaction number, and determines whether the tax exemption condition is satisfied based on the total amount. Determine whether Then, the tax exemption condition determination unit 401 transmits the determination result to the POS terminal 2 that made the request. In addition, if the tax exemption conditions of other transactions are not satisfied by performing the cancellation process, the tax exemption condition determination unit 401 sends information (transaction number , cash register number, total amount, etc.) to the requesting POS terminal 2.

Subsequently, the cancellation processing unit 304 determines whether the tax exemption condition is satisfied based on the determination result transmitted from the server device 4 (step S40). Here, if the tax exemption condition is satisfied (step S40; Yes), the cancellation processing unit 304 moves to step S37, and performs cancellation processing on the transaction data to be processed according to the cancellation details.

On the other hand, if the tax exemption conditions are not met (step S40; No), the cancellation processing unit 304 causes the display unit 22 to display a message confirming that the tax exemption conditions are no longer met (step S41), and waits for an input from the operator. Here, if an operation instructing to cancel the cancellation process is input (step S42; No), the cancellation processing unit 304 ends this process.

Further, when an operation instructing execution of cancellation processing is input (step S42; Yes), the cancellation processing unit 304 executes cancellation processing on the transaction data to be processed according to the cancellation details (step S43). Next, the cancellation processing unit 304 sends a cancellation instruction including the transaction number, cancellation details, etc. in order to reflect the cancellation process executed in step S43 in the corresponding transaction data (tax-exempt transaction data) stored in the server device 4. The information is transmitted to the server device 4 (step S44).

Subsequently, the cancellation processing unit 304 determines whether there is a transaction that deviates from the tax exemption conditions based on the determination result of the server device 4 (step S45). Here, if there is no transaction that deviates from the tax exemption conditions (step S45; No), the cancellation processing unit 304 ends this process.

If there is a transaction that deviates from the tax exemption conditions (step S45; Yes), the cancellation processing unit 304 outputs a receipt for the clerk on which information regarding the transaction that deviates from the tax exemption conditions is printed (step S46), and ends this process. .

As described above, when each of the POS terminals 2 of this embodiment performs a tax-free transaction by operating the tax-free declaration key 211, the total amount of the tax-free transaction and the same user stored in the server device 4 are Based on the total amount of other tax exempt transactions, it is determined whether the tax exempt transaction satisfies the tax exemption conditions. Then, each of the POS terminals 2 executes payment processing for the registered product at a tax-exempt price or a tax-inclusive price that is exempt from tax, depending on the determination result. Then, the POS terminal 2 stores transaction data of the tax-free transaction settled in the payment processing in the server device 4 in association with the transaction number and the user ID.

In addition, when each of the POS terminals 2 of this embodiment receives an instruction to cancel a tax-free transaction or a product paid for as a tax-free transaction by operating the cancellation key 214, each of the POS terminals 2 performs a cancellation process according to the cancellation instruction on the transaction to be processed. Run on data. Then, if there is another tax-free transaction in the server device 4 that deviates from the tax-free conditions due to the cancellation process executed by the POS terminal 2, the POS terminal 2 outputs information regarding the other tax-free transaction. For example, the POS terminal 2 outputs the transaction number of a tax-free transaction that does not meet the tax-free conditions, the cash register number of the POS terminal 2 where the tax-free transaction was performed, the total amount, etc.

This allows the operator of the POS terminal 2 to easily confirm other transactions that fall outside of the tax exemption conditions, making it easy to identify the relevant transaction data and the POS terminal 2 where the transaction occurred. be able to. In this way, in the POS terminal 2 of this embodiment, if the transaction data of another transaction stored in another POS terminal 2 falls outside of the tax exemption conditions due to cancellation processing executed by the POS terminal 2, for example, the transaction data of that transaction is It is easy to identify and operate. Therefore, in this embodiment, it is possible to match the transaction data stored in the sales data processing device and the transaction data stored in the server device 4.

Note that the embodiments described above can be modified and implemented as appropriate by changing part of the configuration or function of each of the devices described above. Therefore, some modified examples of the above-described embodiment will be described below as other embodiments. Note that, below, points that are different from the embodiments described above will be mainly explained, and detailed explanations of points that are common to those already explained will be omitted. Further, the modified examples described below may be implemented individually or in appropriate combinations.

(Modification 1)
In the embodiment described above, when there is a transaction that deviates from the tax exemption conditions due to cancellation processing, a mode has been described in which information regarding the transaction is output. On the other hand, there are existing transactions that will meet the tax exemption conditions as a result of the new payment processing. For example, it is assumed that among the transactions shown in figures (a) to (c) described in FIG. 10, the same user performs transactions (b) and (c) first, and transaction (a) last. In this case, the tax exemption conditions will not be satisfied in the transactions (b) and (c), and the tax exemption conditions will be satisfied in all of (a) to (c) by conducting the transaction (a). In this case, the POS terminal 2 that performs the transaction in (a) cannot easily confirm the transactions in (b) and (c) for which the tax exemption condition has been met.

Therefore, if there is another transaction that satisfies the tax exemption condition due to the newly performed payment processing, the configuration may be such that information regarding the other transaction is output as in the above-described embodiment.

Specifically, the tax exemption condition determination unit 401 of the server device 4 determines whether the tax exemption condition is satisfied in response to a condition determination request transmitted from the tax exemption processing unit 302, as in the above-described embodiment. If the tax exemption condition determination unit 401 determines that the tax exemption condition is satisfied, it determines whether another transaction of the same user for which the tax exemption condition was not satisfied until now has changed to the fulfillment of the tax exemption condition, and if the tax exemption condition has changed to the fulfillment, sends information regarding the other transaction along with the determination result to the requesting POS terminal 2.

On the other hand, when the tax exemption processing unit 302 of the POS terminal 2 performs payment processing (tax exemption processing) in cooperation with the payment processing unit 303, based on the information transmitted from the server device 4, the tax exemption processing unit 302 determines that the tax exemption conditions are established. Determine whether other transactions exist. Then, the tax exemption processing unit 302 displays information regarding other transactions for which the tax exemption conditions have been met or prints out the information as a receipt for a clerk. In other words, the tax exemption processing unit 302 functions as an example of second output control means.

As a result, the operator of the POS terminal 2 can easily confirm other transactions for which tax exemption conditions have been met, making it easy to identify the relevant transaction data and the POS terminal 2 where the transaction occurred. be able to. In this way, in the POS terminal 2 of this modification, if transaction data of another transaction stored in another POS terminal 2 falls under the tax exemption conditions due to tax exemption processing executed by the POS terminal 2, for example, the transaction data is It is easy to identify and operate. Therefore, in this embodiment, it is possible to match the transaction data stored in the sales data processing device and the transaction data stored in the server device 4.

(Modification 2)
In the above-described embodiment, the tax exemption condition determination unit 401 included in the server device 4 determines the tax exemption conditions based on the tax exemption transaction data stored in the server device 4, but the present invention is not limited to this. . For example, by providing each of the POS terminals 2 with a functional unit similar to the tax exemption condition determination unit 401, each of the POS terminals 2 individually determines the tax exemption conditions based on the tax exemption transaction data stored in the server device 4. It may also be a configuration.

In this case, the server device 4 functions, for example, as a database server that stores and manages tax-exempt transaction data, and the tax-exempt condition determination unit 401 included in each POS terminal 2 processes the tax-exempt transaction data stored in the server device 4, etc. , to determine whether the transaction conducted on the own machine satisfies the tax exemption conditions. In this case, the tax exemption condition determining unit 401 of the POS terminal 2 functions as an example of determining means.

In this case, the server device 4 functions, for example, as a database server that stores and manages tax-exempt transaction data, and the tax-exempt condition determination unit 401 included in each POS terminal 2 processes the tax-exempt transaction data stored in the server device 4, etc. , to determine whether the transaction conducted on the own machine satisfies the tax exemption conditions. In this case, the tax exemption condition determining unit 401 of the POS terminal 2 functions as an example of determining means.

(Modification 3)
In the above-described embodiment, each POS terminal 2 is capable of canceling transaction data stored in its own POS terminal 2; however, this is not limited to this, and transaction data stored in other POS terminals 2 is It may also be configured to be able to handle transaction data.

For example, if another transaction executed at another POS terminal 2 deviates from the tax exemption conditions due to the execution of the cancellation process, the cancellation processing unit 304 may cancel the transaction at the other POS terminal 2 based on the cash register number notified from the server device 4. Access 2. Then, the cancellation processing unit 304 invalidates the tax exemption flag of the transaction data whose transaction number does not meet the tax exemption conditions, among the transaction data stored in the transaction management file 262 of the accessed POS terminal 2.

As a result, in the POS terminal 2, if another transaction executed at another POS terminal 2 falls outside the tax exemption conditions due to execution of cancellation processing, the transaction data related to the other transaction can be automatically manipulated. , convenience can be improved. In addition, when operating transaction data, the cancellation processing unit 304 displays a screen on the display unit 22 to prompt the operator to confirm, and when the operation is instructed, it operates on transaction data related to other transactions. Good too.
