Description

[Technical Field]

[0001] An embodiment of the present invention relates to a product sales data processing device and a program. [Background technology]

[0002] Traditionally, there has been a so-called tax exemption system in place that exempts businesses that operate export goods sales outlets (duty-free shops) from paying consumption tax and other taxes on products and other items sold to non-residents, such as foreign tourists.

[0003] To qualify for this tax exemption system, the total sales amount of the goods in the tax-exempt category must be equal to or greater than a specified amount.

[0004] However, in order to know whether the total sales amount of the goods in the tax-exempt category has reached the predetermined amount, the total amount must be calculated separately. Summary of the Invention [Problem to be solved by the invention]

[0005] The problem to be solved by the present invention is to provide a product sales data processing device and program that can output whether or not a product to be sold is tax-exempt. [Means for solving the problem]

[0006] A product sales data processing device according to an embodiment includes an input means, a registration means, a determination means, and a display control means. The input means receives an input of a product code that can identify a product. The registration means registers the product corresponding to the product code received by the input means as a product for sale. The determination means determines whether the total price of the products registered by the registration means exceeds an amount set by a tax exemption system that exempts the products from tax. The display control means displays a tax exemption status indicating whether the products registered by the registration means are exempt from tax, depending on the determination result of the determination means.

[0013] The control unit 400 is connected to a storage unit 405 , a controller 406 , and a communication I / F 407 via a bus line 404 .

[0014] The controller 406 is connected to an operation unit 408, a display unit 409, and a printer 410. The controller 406 controls each of the connected units based on commands from the control unit 400. The operation unit 408 is a keyboard, a mouse, etc. for inputting operations. The display unit 409 is a liquid crystal display, etc. The printer 410 is a printing device that prints out various types of information.

[0015] The communication I / F 407 is connected to the POS terminal 2 and the like via the in-store network 3 .

[0016] 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 a control program PR1 and a product master M. The control program PR1 is a program for enabling the store server 4 to perform characteristic functions.

[0017] The product master M is a database that stores information about each product. 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 goods sold to non-residents such as foreign tourists from taxes. The tax-free categories include "consumables," "general goods," and "non-tax-free." "Consumables" include food, beverages, medicines, cosmetics, and other consumable goods. "General goods" are tax-free goods that are used for everyday life other than consumables. For example, "general goods" include products such as home appliances, clothes, and bags. "Non-tax-free" means goods that are not tax-free. Note that the above-mentioned tax-free categories are merely examples, and other categories may be used.

[0018] 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 includes a control unit 200 for controlling each unit. As shown in FIG. 4, the control unit 200 includes 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 for storing various programs and data. The RAM 203 is a storage medium for temporarily storing various programs and rewriting various data. In addition, a portion of the RAM 203 is used to store a sales product registration table T.

[0019] 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 stores product codes, product names, prices, and tax-free categories in association with each other.

[0020] The control unit 200 is connected to a storage unit 205 , a controller 206 , and a communication I / F 207 via a bus line 204 .

[0021] 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 is also equipped with 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 during the product sales data registration process.

[0022] 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 product name and price 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 the store clerk. The second display unit 210 displays various information mainly for the customer. 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.

[0023] 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.

[0024] The scanner 212 is a laser hand scanner, an optical reading vertical scanner, etc. The scanner 212 optically reads codes such as barcodes and two-dimensional codes attached to products.

[0025] The passport reader 213 is a reader device that reads information held in a passport. In the embodiment, the passport reader 213 has an optical character recognition (OCR) function that optically reads character strings written on a passport.

[0026] The card reader / writer 214 is a device that reads and writes information stored in the storage medium of the card.

[0027] The communication I / F 207 is connected to the store server 4 and the like via the in-store network 3 .

[0028] The storage unit 205 is, for example, a storage device such as an HDD or SSD. The storage unit 205 stores a control program PR2 and a product master M. The control program PR2 is a program for enabling the POS terminal 2 to perform characteristic functions. The product master M is a product master M stored in the storage unit 405 of the store server 4 and transmitted thereto.

[0029] Next, a description will be given of the characteristic functions of each device in the POS system 1. Here, Fig. 6 is a block diagram showing the characteristic functional configuration of each device in the POS system 1.

[0030] First, the characteristic functions of the store server 4 will be described.

[0031] The CPU 401 of the control unit 400 loads the control program PR1 stored in the storage unit 405 into the RAM 403 and operates in accordance with 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.

[0032] The communication control unit 4001 controls the communication I / F 407 to perform communication via the in-store network 3. For example, the communication control unit 4001 transmits the product master data M to the POS terminal 2 periodically.

[0033] Next, the characteristic functions of the POS terminal 2 will be described.

[0034] The CPU 201 of the control unit 200 loads the control program PR2 in the storage unit 205 into the RAM 203 and operates in accordance with the control program PR2 to generate the functional units shown in Fig. 6 on the RAM 203. Specifically, the control unit 200 has, 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.

[0035] The communication control unit 2001 controls the communication I / F 207 to perform communication via the in-store network 3. For example, the communication control unit 2001 receives the product master data M from the store server 4 periodically.

[0036] 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 from the closing key 2081 to complete the registration of the products to be sold and calculate the total sales amount.

[0037] 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 merchandise 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 merchandise sales data registration process does not determine whether or not a transaction is eligible for tax exemption.

[0038] The product registration unit 2004, which is a registration means, registers the product with the product code received by the input control unit 2002 as a product for sale in the sales product registration table T. When the input control unit 2002 receives 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. Then, the product registration unit 2004 registers the read information related 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 received by the input control unit 2002 as a product for sale.

[0039] When the tax-free mode is set, the tax-free control unit 2005 determines whether or not the products for sale are eligible for tax-free exemption. Specifically, the tax-free control unit 2005 calculates the total sales amount of the products for sale registered in the sales product registration table T for each tax-free category. Then, the tax-free control unit 2005, which is a determination means, determines whether or not the total sales amount of the products in the tax-free category is within the range of the tax-free standard amount. That is, the tax-free control unit 2005 determines whether or not the total sales amount of the products in the tax-free category is above the lower limit of the tax-free standard amount. The tax-free control unit 2005 also determines whether or not the total sales amount of the products in the tax-free category is above the upper limit of the tax-free standard amount. If 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 determines that the products in the corresponding tax-free category are eligible for tax-free exemption. On the other hand, if 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 determines that the products in the corresponding tax-free category are not eligible for tax-free exemption. Here, the tax-free threshold amount is a threshold amount set by the tax-free system for exempting taxes. In other words, the tax-free threshold amount is an amount that serves as a benchmark for determining whether or not to exempt products in the tax-free category from tax. A different tax-free threshold amount can be set for each tax-free category. For example, the tax-free threshold amount is set in advance to 5,000 to 500,000 yen for consumables in the tax-free category, and 10,000 yen for general goods in the tax-free category. Then, the tax-free control unit 2005 calculates the tax-free amount for each tax-free category.

[0040] Furthermore, the tax exemption control unit 2005 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. Then, the tax exemption control unit 2005 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 the amount indicating the tax exemption amount for products in the tax exemption category of general goods. The consumable goods tax exemption amount is the amount indicating the tax exemption amount for products in the tax exemption category of consumable goods. The general goods tax exemption remaining amount is the 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 the 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 tax-free amount for consumables is the amount obtained by subtracting the total sales amount of products in the tax-free category from the tax-free standard amount. The total tax-free amount is the total amount of the amounts eligible for tax-free exemption in all tax-free categories. The tax-free amount is the amount exempt from tax. The tax-free amount is the total amount 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 consumables.

[0041] The display control unit 2006 displays various screens on the first display unit 209 and the second display unit 210. The display control unit 2006, which is a display control means, displays, for example, a first product registration screen on the first display unit 209, which is mainly viewed by store clerks. 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, according to the determination result of the tax exemption control unit 2005 in the product sales data registration process set to tax exempt mode.

[0042] 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, number of items, discount, amount, and tax-free category for each product. The product name field displays the product name. The unit price field displays the price of the product. The number of items field displays the number of items sold. The discount field displays the discount amount or discount rate when the price of the product is discounted. The amount field displays the amount obtained by multiplying the price of the product by the number of items sold. The tax-free category field 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, and product D is a product that is not eligible for tax exemption.

[0043] The display control unit 2006 then displays the tax-exempt status, indicating whether or not a product is tax-exempt, 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-exempt status in the product list display area G11 in different display modes depending on whether or not the product is tax-exempt. Different display modes for the tax-exempt status in the product list display area G11 include, for example, changing the color, adding text, displaying animation, adding a mark, changing the font, or changing the display size. The first product registration screen G1 shown in FIG. 7 displays "Tax-exempt" for products that are tax-exempt and "Taxable" for products that are not tax-exempt, as a display mode that allows users to identify whether or not a product is tax-exempt. The first product registration screen G1 shown in FIG. 7 indicates that products A and B are tax-exempt.

[0044] 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.

[0045] The general goods tax exemption amount field G121 is a field that displays the general goods tax exemption amount or the remaining applicable general goods tax exemption amount. The display control unit 2006 displays the tax exemption status, which indicates whether the general goods tax exemption amount or the remaining applicable general goods tax exemption amount is eligible for tax exemption, in the general goods tax exemption amount field G121. The display control unit 2006 also displays the tax exemption status in the general goods tax exemption amount field G121 in different display modes depending on whether the product is exempt from tax. That is, when a product in the tax exemption category of general goods is eligible for tax exemption, the display control unit 2006 displays the general goods tax exemption amount in the general goods tax exemption amount field G121 together with the message "Tax exempt." On the other hand, when the total amount of the products in the tax exemption category of general goods does not exceed the tax exemption threshold amount and therefore is not exempt from tax, the display control unit 2006 displays the remaining applicable general goods tax exemption amount in the general goods tax exemption amount field G121 together with the message "Tax exemption remaining." The general goods tax-exempt amount field G121 shown in Fig. 7 displays "Tax-free 11,000 yen." Note that the display manner for different tax-exempt statuses in the general goods tax-exempt amount field G121 is not limited to the above, and may include changing the color, adding text, displaying with animation, adding a mark, changing the font, changing the display size, etc.

[0046] The consumables tax-exemption amount field G122 is a field that displays the consumables tax-exemption amount or the remaining applicable consumables tax-exemption amount. The display control unit 2006 then displays the tax-exemption status, which indicates whether the consumables tax-exemption amount or the remaining applicable consumables tax-exemption amount is eligible for tax exemption, in the consumables tax-exemption amount field G122. The display control unit 2006 also displays the tax-exemption status in the consumables tax-exemption amount field G122 in different display modes depending on whether the product is exempt from tax. That is, if a product in the tax-exemption category is eligible for tax exemption, the display control unit 2006 displays the consumables tax-exemption amount in the consumables tax-exemption amount field G122 together with the message "Tax-exempt." On the other hand, if the total amount of the products in the tax-exemption category does not exceed the tax-exemption threshold amount and therefore is not exempt from tax, the display control unit 2006 displays the remaining applicable consumables tax-exemption amount in the consumables tax-exemption amount field G122 together with the message "Tax-exempt." The consumables tax-exemption eligible amount field G122 shown in Fig. 7 displays "3,001 yen remaining until tax-exemption." Note that the display manner for different tax-exempt statuses in the consumables tax-exemption eligible amount field G122 is not limited to the above, and may include changing the color, adding text, displaying with animation, adding a mark, changing the font, changing the display size, etc.

[0047] The tax exemption amount field G123 is a field that displays the tax exemption amount for all products that are eligible for tax exemption. The tax exemption amount field G123 shown in Figure 7 displays "11,000 yen." The tax exemption amount field G124 is a field that displays the total amount of tax that is exempt for one transaction. The tax exemption amount field G124 shown in Figure 7 displays "-850 yen."

[0048] 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 price 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.

[0049] Alternatively, the display control unit 2006 may, for example, display a second product registration screen on the second display unit 210, which is primarily viewed by customers. 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 exemption information display area G21, a product display area G22, and a total display area G23. The tax exemption information display area G21 is an area for displaying information related to tax exemption for products registered in the sales product registration table T. Because the display area of ​​the tax exemption information display area G21 is narrow, the display control unit 2006 scrolls and displays the information related to tax exemption for the products registered in the sales product registration table T. That is, the display control unit 2006 scrolls and displays, for example, "General goods tax exemption eligible amount Tax exemption 11,000 yen Consumables tax exemption eligible amount Remaining tax exemption 3,001 yen Total tax exemption amount 11,000 yen Tax exemption 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.

[0050] 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 on the second display unit 210 a screen identical to the tax-exempt information display area G12 of the first product registration screen G1.

[0051] The accounting processing unit 2007 executes accounting processing, which includes processing for receiving the payment with the tax-free amount exempted, and processing for printing a receipt indicating that the payment has been received.

[0052] Next, a description will be given of the merchandise sales data registration process executed by the POS terminal 2. Here, Fig. 9 is a flowchart illustrating an example of the merchandise sales data registration process executed by the POS terminal 2 according to the embodiment.

[0053] First, when the mode control unit 2003 of the POS terminal 2 detects that the tax-free mode key 2082 has been pressed, it sets the mode to tax-free mode (step S1).

[0054] 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.

[0055] On the other hand, if a product code is input (step S2; Yes), the product registration unit 2004 of the POS terminal 2 extracts information associated with the input product code from the product master M (step S3).

[0056] 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).

[0057] Next, the tax exemption control unit 2005 of the POS terminal 2 calculates the total sales amount of the tax exempt category of the merchandise registered in the sales merchandise registration table T (step S5).

[0058] 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). That is, 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.

[0059] If a product in the tax-free category registered in the sales product registration table T becomes 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).

[0060] 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 item 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 field G121 in a display mode that makes it possible to identify that the item is tax exempt. Alternatively, the display control unit 2006 displays the consumables tax exemption amount in the consumables tax exemption amount field G122 in a display mode that makes it possible to identify that the item is tax exempt.

[0061] 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).

[0062] Next, the display control unit 2006 of the POS terminal 2 displays the tax exemption amount in the tax exemption amount column G124 (step S10).

[0063] Next, the display control unit 2006 of the POS terminal 2 causes the second display unit 210 to display the information related to tax exemption that has been 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 information related to tax exemption 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 information related to tax exemption on the second display unit 210 earlier than steps S8 to S10.

[0064] On the other hand, if a 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 identifiable that the product is not subject to tax exemption (step S12).

[0065] Next, the display control unit 2006 of the POS terminal 2 displays the remaining tax exemption amount in a display mode that makes it possible to identify that the item is not subject to tax exemption (step S13). That is, the display control unit 2006 displays the remaining general goods tax exemption amount in the general goods tax exemption amount field G121 in a display mode that makes it possible to identify that the item is not subject to tax exemption. Alternatively, the display control unit 2006 displays the remaining consumable goods tax exemption amount in the consumable goods tax exemption amount field G122 in a display mode that makes it possible to identify that the item is not subject to tax exemption.

[0066] Next, the display control unit 2006 of the POS terminal 2 causes the second display unit 210 to display the information related to tax exemption displayed in step S13 (step S14). Note that the timing when the display control unit 2006 causes the second display unit 210 to display the information related to tax exemption is not limited to this timing, and may be the same as step S13. Alternatively, the display control unit 2006 may display the information related to tax exemption on the second display unit 210 earlier than step S13.

[0067] 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.

[0068] If 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 receiving the price with the tax-free amount exempted (step S16).

[0069] With the above, the POS terminal 2 ends the product sales data registration process.

[0070] As described above, in the POS terminal 2 according to 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 the information in the sales product registration table T. The tax exemption control unit 2005 then determines whether the total sales amount of the products registered in the sales product registration table T exceeds the amount specified by the tax exemption system. The display control unit 2006 then displays the tax exemption status, indicating whether the product for sale is exempt from tax, on the first product registration screen G1 according to the determination result of the tax exemption control unit 2005. Therefore, the POS terminal 2 according to this embodiment can output whether the product for sale is tax exempt. This allows the store clerk to announce to the customer whether the product is tax exempt. Furthermore, the customer himself can recognize whether the product is tax exempt.
