Description

An embodiment of the present invention relates to a product sales data processing device and a program.

Traditionally, there has been a so-called tax exemption system that exempts businesses operating export goods sales outlets (duty-free shops) from paying consumption tax and other taxes on items sold when they sell such items to non-residents, such as foreign tourists.

To qualify for this tax exemption system, the total sales amount of the tax-exempt items must be equal to or exceed a certain amount.

However, to know whether the total sales amount of the tax-exempt items reached the required amount, a separate calculation had to be made.

The problem that this invention aims to solve is to provide a product sales data processing device and program that can output whether or not a product for sale is tax-free.

A product sales data processing device according to an embodiment includes an input means, a registration means, a calculation means, a determination means, and a display control means. The input means accepts input of a product code capable of identifying a product. The registration means registers the product of the product code accepted by the input means as a product for sale. The calculation means calculates a total price of the products for sale registered by the registration means for each tax-free category related to a tax-free system. The determination means determines whether the total price of the products registered by the registration means for each tax-free category calculated by the calculation means satisfies the tax-free condition for each tax-free category defined in the tax-free system for tax exemption. The display control means causes a display unit to display information indicating whether or not the tax is exempt for each tax-free category according to the determination result of the determination means each time the input of the product code is accepted by the input means.

Embodiments of a product sales data processing device and a program will be described in detail below with reference to the attached drawings. Note that the embodiment described below is one embodiment of the product sales data processing device and program, and does not limit the configuration or specifications. The product sales data processing device of this embodiment is an example of application to a POS (Point Of Sales) terminal installed in a store such as a duty-free shop, which processes product sales data related to the registration and settlement of products in one transaction.

Figure 1 is an explanatory diagram showing an example of the configuration of a POS system 1 according to this embodiment. The POS system 1 includes a POS terminal 2 and a store server 4. The POS system 1 connects the POS terminal 2 and the store server 4 via an in-store network 3. The in-store network 3 is, for example, a LAN (Local Area Network) that connects the various devices installed in the store.

The POS terminal 2 is a product sales data processing device used to process product sales data in stores such as duty-free shops where products can be sold without paying taxes. The store server 4 is an information processing device that provides overall management of the POS terminals 2 installed in the store.

Next, we will explain the hardware configuration of the POS terminal 2 and the store server 4.

First, the hardware configuration of the store server 4 will be described. FIG. 2 is a block diagram showing the hardware configuration of the store server 4.

The control unit 400 is connected to the memory unit 405, the controller 406, and the communication I/F 407 via the bus line 404.

The controller 406 is connected to an operation unit 408, a display unit 409, and a printer 410. The controller 406 controls each connected unit based on commands from the control unit 400. The operation unit 408 is a keyboard, mouse, etc. for inputting operations. The display unit 409 is a liquid crystal display, etc. The printer 410 is a printing device that prints various information.

The communication I/F 407 connects to the POS terminal 2 etc. via the in-store network 3.

The storage unit 405 is, for example, a storage device such as a hard disk drive (HDD) or a solid state drive (SSD). The storage unit 405 stores the control program PR1 and the product master M. The control program PR1 is a program for implementing the characteristic functions of the store server 4.

The product master M is a database that stores information about each product. Here, FIG. 3 is an explanatory diagram showing an example of the product master M. The product master M stores information about each product. The product master M stores a product code, a product name, a price, and a tax-free category in association with each other. The product code is identification information that can identify a product. The product name is the name of the product. The price is the price of the product. The tax-free category is a category related to the tax-free system that exempts products sold to non-residents such as foreign tourists from taxes. The tax-free categories include "consumables", "general goods", and "non-tax-free". "Consumables" include foods, beverages, medicines, cosmetics, and other consumable products. "General goods" are goods that are tax-free and are used for everyday life other than consumables. For example, "general goods" include products such as home appliances, clothes, and bags. "Non-tax-free" are goods that are not tax-free. Note that the above-mentioned tax-free categories are only examples, and other categories may be used.

Next, the hardware configuration of the POS terminal 2 will be described. FIG. 4 is a block diagram showing the hardware configuration of the POS terminal 2. The POS terminal 2 has a control unit 200 for controlling each unit. As shown in FIG. 4, the control unit 200 has a CPU 201, a ROM 202, and a RAM 203. The CPU 201 is connected to the ROM 202 and the RAM 203 via a bus line 204 such as an address bus and a data bus. The CPU 201 centrally controls each unit. The ROM 202 is a storage medium that stores various programs and data. The RAM 203 is a storage medium that temporarily stores various programs and rewrites various data. In addition, a portion of the RAM 203 is used to store the sales product registration table T.

The sales product registration table T stores products for sale. FIG. 5 is an explanatory diagram showing an example of the sales product registration table T. The sales product registration table T stores product information for each product for sale. The product information is stored in association with the product code, product name, price, and tax-free category.

The control unit 200 is connected to the memory unit 205, the controller 206, and the communication I/F 207 via the bus line 204.

The controller 206 is connected to an operation unit 208, a first display unit 209, a second display unit 210, a printer 211, a scanner 212, a passport reader 213, and a card reader/writer 214. The operation unit 208 is a keyboard, a mouse, etc. for inputting operations. The operation unit 208 also has a closing key 2081 and a tax-free mode key 2082. The closing key 2081 is a key for completing the registration of products for sale and calculating the total sales amount. The tax-free mode key 2082 is a key for setting the tax-free mode. Here, the tax-free mode is a mode for determining whether or not a transaction is eligible for tax exemption in the product sales data registration process.

The first display unit 209 and the second display unit 210 are, for example, display devices such as liquid crystal displays. The first display unit 209 and the second display unit 210 display various information such as the name and price of the product registered by the product sales data processing, the total amount of a transaction for which payment has been declared, and the amount of change. The first display unit 209 displays various information mainly for store clerks. The second display unit 210 displays various information mainly for customers. The first display unit 209 and the second display unit 210 may be equipped with a touch panel. In this case, the touch panel functions as the operation unit 208.

The printer 211 is a printing device that prints receipts, journals, etc. The printer 211 prints receipt information on paper such as roll paper and outputs a paper receipt.

Scanner 212 may be a laser hand scanner or an optical reading vertical scanner. Scanner 212 optically reads codes such as bar codes and two-dimensional codes attached to products.

The passport reader 213 is a reader device that reads information held on a passport. In the embodiment, the passport reader 213 has an optical character recognition (OCR) function that optically reads character strings written on the passport.

The card reader/writer 214 is a device that reads and writes information stored in the card's storage medium.

The communication I/F 207 connects to the store server 4 etc. via the in-store network 3.

The memory unit 205 is, for example, a storage device such as an HDD or SSD. The memory unit 205 stores a control program PR2 and a product master M. The control program PR2 is a program for implementing the characteristic functions of the POS terminal 2. The product master M is the product master M stored in the memory unit 405 of the store server 4 and transmitted to the memory unit 205.

Next, we will explain the characteristic functions of each device in the POS system 1. Here, Figure 6 is a block diagram showing the characteristic functional configuration of each device in the POS system 1.

First, we will explain the characteristic functions of the store server 4.

The CPU 401 of the control unit 400 loads the control program PR1 in the storage unit 405 onto the RAM 403, and operates according to the control program PR1 to generate the functional units shown in FIG. 6 on the RAM 403. Specifically, the control unit 400 includes a communication control unit 4001 as a functional unit.

The communication control unit 4001 controls the communication I/F 407 to communicate via the in-store network 3. For example, the communication control unit 4001 periodically transmits the product master M to the POS terminal 2.

Next, we will explain the characteristic functions of the POS terminal 2.

The CPU 201 of the control unit 200 loads the control program PR2 in the storage unit 205 into the RAM 203 and operates according to the control program PR2 to generate the functional units shown in FIG. 6 on the RAM 203. Specifically, the control unit 200 includes, as functional units, a communication control unit 2001, an input control unit 2002, a mode control unit 2003, a product registration unit 2004, a tax exemption control unit 2005, a display control unit 2006, and an accounting processing unit 2007.

The communication control unit 2001 controls the communication I/F 207 to communicate via the in-store network 3. For example, the communication control unit 2001 periodically receives the product master M from the store server 4.

The input control unit 2002, which is an input means, accepts input of a product code from the scanner 212 or the like. Alternatively, the input control unit 2002 accepts input of a product code from the operation unit 208. Alternatively, the input control unit 2002 accepts input to set the tax-free mode from the tax-free mode key 2082. Furthermore, the input control unit 2002 accepts input to end the registration of products for sale and calculate the total sales amount from the closing key 2081.

The mode control unit 2003 controls mode changes. Specifically, when the input control unit 2002 receives an input to set the POS terminal 2 to the tax-free mode, the mode control unit 2003 sets the POS terminal 2 to the tax-free mode. Then, when the product sales data registration process in the tax-free mode is completed, the mode control unit 2003 sets the POS terminal 2 to the normal mode. The normal mode is a mode in which the product sales data registration process does not determine whether or not a transaction is eligible for tax exemption.

The product registration unit 2004, which is a registration means, registers the product with the product code accepted by the input control unit 2002 as a product for sale in the sales product registration table T. When the input control unit 2002 accepts the product code of a product for sale, the product registration unit 2004 reads information associated with the product code from the product master M. The product registration unit 2004 then registers the read information relating to the product for sale as product information in the sales product registration table T. In this way, the product registration unit 2004 registers the product with the product code accepted by the input control unit 2002 as a product for sale.

When the tax-free mode is set, the tax-free control unit 2005 judges whether the product to be sold is subject to tax-free. Specifically, the tax-free control unit 2005 calculates the total sales amount of the products to be sold registered in the sales product registration table T for each tax-free category. Then, the tax-free control unit 2005, which is the judgment means, judges whether the total sales amount of the products in the tax-free category is within the range of the tax-free standard amount. In other words, the tax-free control unit 2005 judges whether the total sales amount of the products in the tax-free category exceeds the lower limit of the tax-free standard amount. In addition, the tax-free control unit 2005 judges whether the total sales amount of the products in the tax-free category exceeds the upper limit of the tax-free standard amount. When the total sales amount of the products in the tax-free category is within the range of the tax-free standard amount, the tax-free control unit 2005 judges that the products in the corresponding tax-free category are subject to tax-free. On the other hand, when the total sales amount of the products in the tax-free category is outside the range of the tax-free standard amount, the tax-free control unit 2005 judges that the products in the corresponding tax-free category are not subject to tax-free. Here, the tax-free standard amount is a threshold amount set by the tax-free system for exemption from tax. In other words, the tax-free standard amount is an amount that serves as a benchmark for whether or not to exempt products in the tax-free category from tax. A different tax-free standard amount can be set for each tax-free category. For example, the tax-free standard amount is set in advance to 5,000 yen to 500,000 yen for consumables and 10,000 yen for general goods. The tax-free control unit 2005 then calculates the tax-free amount for each tax-free category.

The tax exemption control unit 2005 also calculates the general goods tax exemption amount, the consumable goods tax exemption amount, the general goods tax exemption remaining amount, the consumable goods tax exemption remaining amount, the total tax exemption amount, and the tax exemption amount. The tax exemption control unit 2005 then displays the calculated amounts on the first display unit 209 and the second display unit 210. This allows the store clerk and the customer to understand the tax exemption status. The general goods tax exemption amount is an amount indicating the tax exemption amount for products in the tax exemption category of general goods. The consumable goods tax exemption amount is an amount indicating the tax exemption amount for products in the tax exemption category of consumable goods. The general goods tax exemption remaining amount is an amount indicating the remaining amount up to the tax exemption standard amount for general goods required to be eligible for tax exemption. In other words, the general goods tax exemption remaining amount is the amount obtained by subtracting the total sales amount of products in the tax exemption category from the tax exemption standard amount. The consumable goods tax exemption remaining amount is an amount indicating the remaining amount up to the tax exemption standard amount for consumable goods required to be eligible for tax exemption. In other words, the remaining amount applicable to tax-free consumables is the tax-free standard amount minus the total sales amount of products in the tax-free category. The total tax-free amount is the total amount applicable to tax-free in all tax-free categories. The tax-free amount is the amount that is exempt from tax. The tax-free amount is the sum of the tax-free amount for products in the tax-free category of general goods and the tax-free amount for products in the tax-free category of consumable goods.

The display control unit 2006 causes various screens to be displayed on the first display unit 209 and the second display unit 210. The display control unit 2006, which is a display control means, causes, for example, the first product registration screen to be displayed on the first display unit 209 which is mainly seen by the store clerk. Here, FIG. 7 is an explanatory diagram showing an example of the first product registration screen G1. The first product registration screen G1 is a screen that displays the tax exemption status, which indicates whether or not the product to be sold is exempt from tax, depending on the determination result of the tax exemption control unit 2005 in the product sales data registration process set to tax-free mode.

The first product registration screen G1 is broadly divided into a product list display area G11, a tax-free information display area G12, and a total display area G13. The product list display area G11 is an area that displays product information of products registered in the sales product registration table T. The product list display area G11 has columns that display the product name, unit price, points, discount, amount, and tax-free category for each product. The product name displays the product name. The unit price displays the price of the product. The points display the number of points sold. The discount displays the discount amount or discount rate when the price of the product is discounted. The amount displays the amount obtained by multiplying the price of the product by the number of points sold. The tax-free category displays the tax-free category of the product. The product list display area G11 shown in FIG. 7 indicates that product A and product B are general goods, product C is a consumable product, and product D is a product that is not subject to tax exemption.

The display control unit 2006 then displays the tax-free status, which indicates whether or not the product is exempt from tax, in the product list display area G11 for each product registered in the sales product registration table T. The display control unit 2006 also displays the tax-free status in the product list display area G11 in different display modes depending on whether or not the product is exempt from tax. The different display modes of the tax-free status in the product list display area G11 include, for example, changing the color, adding a character string, displaying an animation, adding a mark, changing the font, changing the display size, and the like. The first product registration screen G1 shown in FIG. 7 displays "tax-free" for products that are tax-free and "taxable" for products that are not tax-free, as a display mode that allows identification of whether or not the product is tax-free. The first product registration screen G1 shown in FIG. 7 indicates that products A and B are tax-free products.

The tax exemption information display area G12 is an area that displays information related to tax exemption for products registered in the sales product registration table T. The tax exemption information display area G12 includes a general goods tax exemption amount column G121, a consumable goods tax exemption amount column G122, a tax exemption amount column G123, and a tax exemption amount column G124. The general goods tax exemption amount column G121 and the consumable goods tax exemption amount column G122 are columns that display the amount of tax exemption for each tax exemption category.

The general goods tax exemption amount column G121 is a column that displays the general goods tax exemption amount or the general goods tax exemption remaining amount. The display control unit 2006 displays the tax exemption status indicating whether the general goods tax exemption amount or the general goods tax exemption remaining amount is subject to tax exemption in the general goods tax exemption amount column G121. The display control unit 2006 also displays the tax exemption status in the general goods tax exemption amount column G121 in different display modes depending on whether the product is exempt from tax. That is, when a product with a tax exemption category of general goods is subject to tax exemption, the display control unit 2006 displays the general goods tax exemption amount in the general goods tax exemption amount column G121 together with the message "tax exempt". On the other hand, when the total amount of the products with a tax exemption category of general goods does not exceed the tax exemption standard amount and is not exempt from tax, the display control unit 2006 displays the general goods tax exemption remaining amount in the general goods tax exemption amount column G121 together with the message "tax exemption remaining". The general goods tax-free amount column G121 shown in FIG. 7 displays "tax-free 11,000 yen." Note that the display manner of the different tax-free status in the general goods tax-free amount column G121 is not limited to the above, and may be a change in color, addition of text, animation, addition of a mark, change in font, change in display size, etc.

The consumables tax-free amount column G122 is a column that displays the consumables tax-free amount or the remaining amount applicable for tax-free consumables. The display control unit 2006 then displays the tax-free status indicating whether the consumables tax-free amount or the remaining amount applicable for tax-free consumables is subject to tax-free in the consumables tax-free amount column G122. The display control unit 2006 also displays the tax-free status in the consumables tax-free amount column G122 in different display modes depending on whether the product is exempt from tax. That is, when a product classified as a consumable is subject to tax-free, the display control unit 2006 displays the consumables tax-free amount in the consumables tax-free amount column G122 together with the message "tax-free". On the other hand, when the total amount of the products classified as consumables is not exempt from tax because it does not exceed the tax-free standard amount, the display control unit 2006 displays the remaining amount applicable for tax-free consumables in the consumables tax-free amount column G122 together with the message "tax-free". The consumables tax-free amount field G122 shown in FIG. 7 displays "3,001 yen remaining until tax-free." Note that the display manner of the different tax-free status in the consumables tax-free amount field G122 is not limited to the above, and may be a change in color, addition of text, animation, addition of a mark, change in font, change in display size, etc.

The tax exemption amount column G123 is a column that displays the tax exemption amount for all products that are eligible for tax exemption. The tax exemption amount column G123 shown in FIG. 7 displays "11,000 yen." The tax exemption amount column G124 is a column that displays the total amount of tax that is exempt for one transaction. The tax exemption amount column G124 shown in FIG. 7 displays "-850 yen."

The total display area G13 is an area that displays the total price of the products registered in the sales product registration table T. The total display area G13 includes a total product number display field, a total amount display field, a deposit display field, and a billing balance display field. The total product number display field is a field that displays the total number of products registered in the sales product registration table T. The total amount display field is a field that displays the total amount of the products registered in the sales product registration table T. The deposit display field is a field that displays the amount deposited by the customer. The billing balance display field is a field that displays the remaining amount of the bill.

Alternatively, the display control unit 2006, for example, displays the second product registration screen on the second display unit 210 which is mainly viewed by the customer. Here, FIG. 8 is an explanatory diagram showing an example of the second product registration screen G2. The second product registration screen G2 includes a tax-free information display area G21, a product display area G22, and a total display area G23. The tax-free information display area G21 is an area for displaying information related to tax-free of products registered in the sales product registration table T. Since the display area of the tax-free information display area G21 is narrow, the display control unit 2006 scrolls and displays information related to tax-free of products registered in the sales product registration table T. That is, the display control unit 2006 scrolls and displays, for example, "General goods tax-free amount Tax-free 11,000 yen Consumable goods tax-free amount Remaining tax-free 3,001 yen Total tax-free amount 11,000 yen Tax-free amount -850 yen". The product display area G22 is an area that displays the product name of the most recent product registered in the sales product registration table T. The total display area G23 is an area that displays the total price of the products registered in the sales product registration table T.

The display control unit 2006 scrolls the display because the display area of the second display unit 210 is small. However, the display method is not limited to this, and the display control unit 2006 may display a screen that is the same as the tax-free information display area G12 of the first product registration screen G1 on the second display unit 210.

The accounting processing unit 2007 executes accounting processing. Here, accounting processing includes processing for receiving the price excluding the tax-free amount and processing for printing a receipt indicating that the price has been received.

Next, the product sales data registration process executed by the POS terminal 2 will be described. Here, FIG. 9 is a flow chart diagram showing an example of the product sales data registration process executed by the POS terminal 2 of the embodiment.

First, when the mode control unit 2003 of the POS terminal 2 detects pressing of the tax-free mode key 2082, it sets the mode to tax-free mode (step S1).

Next, the product registration unit 2004 of the POS terminal 2 determines whether or not a product code is input (step S2). If a product code is not input (step S2; No), the product registration unit 2004 of the POS terminal 2 proceeds to step S15.

On the other hand, if a product code is entered (step S2; Yes), the product registration unit 2004 of the POS terminal 2 extracts information associated with the entered product code from the product master M (step S3).

Next, the product registration unit 2004 of the POS terminal 2 registers the information extracted from the product master M as product information in the sales product registration table T (step S4).

Next, the tax-free control unit 2005 of the POS terminal 2 calculates the total sales amount of the tax-free category of the products registered in the sales product registration table T (step S5).

Next, the tax exemption control unit 2005 of the POS terminal 2 determines whether the total sales amount of the tax exemption category exceeds the tax exemption threshold amount (step S6). In other words, the tax exemption control unit 2005 of the POS terminal 2 determines whether the products in the tax exemption category registered in the sales product registration table T are eligible for tax exemption.

When a product in the tax-free category registered in the sales product registration table T is eligible for tax exemption (step S6; Yes), the display control unit 2006 of the POS terminal 2 displays in the product list display area G11 in a manner that makes it identifiable that the product is eligible for tax exemption (step S7).

Next, the display control unit 2006 of the POS terminal 2 displays the tax exemption amount in a display mode that makes it possible to identify that the amount is tax exempt (step S8). That is, the display control unit 2006 displays the general goods tax exemption amount in the general goods tax exemption amount column G121 in a display mode that makes it possible to identify that the amount is tax exempt. Alternatively, the display control unit 2006 displays the consumables tax exemption amount in the consumables tax exemption amount column G122 in a display mode that makes it possible to identify that the amount is tax exempt.

Next, the display control unit 2006 of the POS terminal 2 displays the total tax exemption amount in the tax exemption amount column G123 (step S9).

Next, the display control unit 2006 of the POS terminal 2 displays the tax-free amount in the tax-free amount column G124 (step S10).

Next, the display control unit 2006 of the POS terminal 2 causes the second display unit 210 to display the tax-exempt information displayed from step S8 to step S10 (step S11). Note that the timing at which the display control unit 2006 causes the second display unit 210 to display the tax-exempt information is not limited to this timing, and may be the same as steps S8 to S10. Alternatively, the display control unit 2006 may display the tax-exempt information on the second display unit 210 earlier than steps S8 to S10.

On the other hand, if the product in the tax-free category registered in the sales product registration table T is not subject to tax exemption (step S6; No), the display control unit 2006 of the POS terminal 2 displays in the product list display area G11 in a manner that makes it easy to identify that the product is not subject to tax exemption (step S12).

Next, the display control unit 2006 of the POS terminal 2 displays the remaining amount applicable for tax exemption in a display manner that makes it possible to identify that the amount is not subject to tax exemption (step S13). That is, the display control unit 2006 displays the remaining amount applicable for general goods tax exemption in the general goods tax exemption amount column G121 in a display manner that makes it possible to identify that the amount is not subject to tax exemption. Alternatively, the display control unit 2006 displays the remaining amount applicable for consumable goods tax exemption in the consumable goods tax exemption amount column G122 in a display manner that makes it possible to identify that the amount is not subject to tax exemption.

Next, the display control unit 2006 of the POS terminal 2 causes the second display unit 210 to display the tax exemption information displayed in step S13 (step S14). Note that the timing at which the display control unit 2006 causes the second display unit 210 to display the tax exemption information is not limited to this timing, and may be the same as step S13. Alternatively, the display control unit 2006 may display the tax exemption information on the second display unit 210 earlier than step S13.

Next, the input control unit 2002 of the POS terminal 2 determines whether or not pressing of the closing key 2081 is detected (step S15). If pressing of the closing key 2081 is not detected (step S15; No), the input control unit 2002 of the POS terminal 2 proceeds to step S2.

When pressing of the closing key 2081 is detected (step S15; Yes), the accounting processing unit 2007 of the POS terminal 2 executes accounting processing such as processing to receive the amount excluding the tax-exempt amount (step S16).

The POS terminal 2 then completes the product sales data registration process.

As described above, according to the POS terminal 2 of this embodiment, the product registration unit 2004 extracts information associated with the product code received by the input control unit 2002 from the product master M and registers it in the sales product registration table T. Then, the tax exemption control unit 2005 judges whether the total sales amount of the products registered in the sales product registration table T exceeds the amount set by the tax exemption system.
