Description

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

In the past, a so-called tax exemption system exempts the consumption tax and other taxes imposed on the goods when a business operator who operates an export goods sales floor (duty-free shop) sells goods to non-residents such as foreign tourists. exists.

In such a tax exemption system, commodities subject to tax exemption are classified into consumables and general commodities.

By the way, with the revision of the tax exemption system law in 2018, it became possible to change the category of general goods to the category of consumables and exempt them from taxation. However, conventionally, in order to change the category of general goods to the category of consumables, it was necessary to cancel all sales registration processing for all target products and start over.

The problem to be solved by the present invention is to provide a sales data processing device and program capable of efficiently changing the classification of general goods to the classification of consumable goods.

The sales data processing device according to the embodiment exempts tax exemption based on the total amount of the purchased products classified as general goods and consumables from among the purchased products. A condition judgment unit that judges whether the conditions are satisfied, and a tax exemption processing unit that performs tax exemption processing to exempt the tax for the target product of the category judged by the condition judgment unit to satisfy the conditions for tax exemption. a designation unit that designates a target product classified as a general product among the target products; a designation determination unit that determines whether the target product is designated by the designation unit; and a classification change unit that changes the classification of the target product determined to be designated by the designation determination unit to the classification of the consumables.

In the embodiment, a POS (Point Of Sales) system used in an export goods sales area (duty-free shop) that sells sales items for daily life to non-residents such as foreign tourists by a certain method. will be explained. The embodiment will be described using a POS terminal installed in a duty-free shop as an example of a sales data processing device.

FIG. 1 is a schematic configuration diagram of a POS system 1 according to an embodiment. As shown in FIG. 1, the POS system 1 includes one or a plurality of (two in the figure) POS terminals 2 installed in a duty-free shop, and these POS terminals 2 connected to a network such as a LAN (Local Area Network). 3 is an information processing device for centralized control, and includes a server 4 installed in the backyard of a duty-free shop, for example.

The server 4 is in charge of controlling the POS system 1 as a whole. The server 4 stores a product master (described later with reference to FIG. 3), a tax exemption category file (described later with FIG. 4), and a tax exemption set value file (described later with FIG. 5). The server 4 transmits the product master, the tax exemption classification file, and the tax exemption setting value file to each POS terminal 2 . The server 4 receives, aggregates, and manages product information and payment information of products for which payment has been processed at each POS terminal 2 .

The POS terminal 2 is arranged at the checkout place inside the duty-free shop. The POS terminal 2 is a terminal for performing transaction processing based on the product code entered by the operator (cashier).

The POS terminal 2 performs transaction processing related to sales of products sold in the store. As the operator operates the POS terminal 2, the POS terminal 2 executes sales registration processing and payment processing for the merchandise to be sold. The sales registration process is to acquire the product code by optically reading the code such as the bar code attached to the product to be sold or by imaging the code, and create the product master based on the acquired product code. This refers to the process of reading product information (product name, price, tax exemption classification code, etc.) of the product from the product, displaying the read product information of the product, and storing the product information in the product information section 331 (see FIG. 2). . Settlement processing is based on the product information stored in the product information unit 331 along with the sales registration processing, displaying the total amount and tax amount related to the transaction, and calculating and displaying the change based on the deposit received from the customer. processing, processing for instructing the change dispenser to issue change, processing for issuing a receipt on which product information and payment information (total amount, deposit amount, amount of change, etc.) are printed. A combination of sales registration processing and settlement processing is called transaction processing.

Next, hardware of the POS terminal 2 will be described. FIG. 2 is a block diagram showing the hardware configuration of the POS terminal 2. As shown in FIG. As shown in FIG. 2, the POS terminal 2 includes a CPU (Central Processing Unit) 31, a ROM (Read Only Memory) 32, a RAM (Random Access Memory) 33, a memory section 34, and the like. The CPU 31 is the controlling subject. The ROM 32 stores various programs. The RAM 33 develops programs and various data. The memory unit 34 stores various programs. The CPU 31 , ROM 32 , RAM 33 and memory section 34 are connected to each other via a bus 35 . The CPU 31 , ROM 32 and RAM 33 constitute a control section 300 . That is, the control unit 300 executes control processing of the POS terminal 2, which will be described later, by the CPU 31 operating according to the control program stored in the ROM 32 and the memory unit 34 and developed in the RAM 33. FIG.

The RAM 33 has a product information section 331 . The product information section 331 stores product information (product name, price, tax exemption classification code (see FIG. 3), etc.) of the product acquired from the product master F1.

The memory unit 34 is composed of an HDD (Hard Disc Drive), a flash memory, or the like, and maintains stored contents even when the power is turned off. The memory unit 34 includes a control program unit 341, a product master F1, a tax exemption classification file F2, and a tax exemption setting value file F3. The product master F1, the tax exemption classification file F2, and the tax exemption setting value file F3 are downloaded from the server 4. FIG. The control program section 341 stores a program for controlling the POS terminal 2 .

Next, the data configuration of the product master F1 will be described. The product master F1 stores the product information of the product in association with the product code that identifies the product. The product master F1 also stores the tax exemption category of the product in association with the product code.

FIG. 3 is a diagram showing an example of the data structure of the product master F1. As shown in FIG. 3, in the product master F1, the product name, product price (unit price), classification code (classification 1 code, classification 2 code), tax exemption classification code 342, dangerous goods classification code, etc. are set. Dangerous Goods Classification Codes are assigned to products that require careful handling, such as sprays that are prohibited from being carried on board an aircraft.

Products are classified by a plurality of classification codes, and the plurality of classifications are constructed hierarchically.

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

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

Next, the tax exempt classification file F2 will be described. FIG. 4 is a diagram showing an example of the data structure of the tax exempt classification file F2. As shown in FIG. 4, in the tax exemption classification file F2, tax exemption classification names are set in association with tax exemption classification codes. The tax exemption category names are "consumables", "general goods", and "not subject to tax exemption". “Consumables” are tax-exempt items that are exempted from taxes on items sold to non-residents such as foreign tourists. classified. "General goods" are also goods subject to tax exemption, and are classified into goods used in ordinary life other than consumables, such as home electric appliances, bags, and clothing. "Exempt from tax exemption" is a non-tax exempt item that is not eligible for tax exemption. The tax exemption classification code of "consumables" is "01". The tax exemption classification code of "general goods" is "02". The tax exemption classification code of "not subject to tax exemption" is "03". The tax exemption classification code 342 of the product master F1 stores one of "01", "02", and "03". Consumables that are exempted from duty are packed and sealed together. General goods exempted from duty are not packed together.

Next, the tax exemption setting value file F3 will be explained. FIG. 5 is a diagram showing an example of the data configuration of the tax exemption set value file F3. As shown in FIG. 5, in the tax exemption setting value file F3, setting values of conditions for tax exemption (that is, tax exemption can be obtained) are set in association with tax exemption category codes. The set value is a guideline for sales registration as tax exempt in each category. In the example shown in FIG. 5, the set value for the consumables with the tax exemption classification code "01" is that the total amount (excluding tax) of the target product is 5,000 yen or more and 500,000 yen or less. That is, if the total amount of the consumables is 5,000 yen or more and 500,000 yen or less, the consumables are tax exempt. In addition, the set value for general goods with the tax exemption classification code "02" is that the total amount (excluding tax) of the target goods is 5,000 yen or more. In other words, if the total amount of the general goods is 5,000 yen or more, the general goods are tax exempt.

Returning to the description of FIG. Also, the POS terminal 2 is connected via a bus 35 and a controller 44 to an operation unit 36, an operator display unit 37 which is a liquid crystal display device having a touch panel on the display surface, a customer display unit 38, a printer 39, a code reader, and so on. 40, passport reader 41, card reader/writer (R/W) 42, etc. are connected.

The operation unit 36 is a keyboard including touch keys provided on the operator display unit 37 and the customer display unit 38 . The operation unit 36 includes a closing key K1, a tax exemption key K2, a special packing key K3, a designation key K4, an enter key K5, and a tax exemption enter key K6.

The closing key K1 is operated to end the transaction with one customer. The tax exemption key K2 is operated when the purchased product is subject to the tax exemption system. The special packing key K3 is operated when declaring a change from the classification of general goods to the classification of consumables for the target product. The designation key K4 (designation portion) is operated to designate general goods to be changed to the consumables category. The confirmation key K5 is operated to confirm the change to the category of consumables. The tax exemption determination key K6 is operated to determine the tax exemption category of the purchased product.

The operator display section 37 displays information for the operator. The customer display unit 38 displays information for customers. The printer 39 issues a receipt on which product information and payment information of the product purchased by the customer are printed. The code reader 40 optically or images a symbol such as a bar code attached to the product and inputs the symbol. The POS terminal 2 analyzes the input symbol and obtains a product code that identifies the product. The passport reader 41 is a reader device that reads information held by a passport (passport). In the embodiment, the passport reader 41 has an optical character recognition (OCR) function of optically reading a character string written on a passport. A card reader/writer (R/W) 42 reads customer information and the like necessary for settlement of transactions from a card held by the customer (for example, a credit card or electronic money).

The POS terminal 2 also has a communication interface (I/F) 43 for data communication with the server 4, which is a host device, via the network 3 provided in the store. This communication interface 43 is also connected to the bus 35 .

From here, the functional configuration of the POS terminal 2 will be described. FIG. 6 is a functional block diagram showing the functional configuration of the POS terminal. By following the control program stored in the control program unit 341, the control unit 300 performs a condition determination unit 301, a tax exemption processing unit 302, a designation determination unit 303, a classification change unit 304, a designation prohibition unit 305, and a general goods display unit 306. function as

The condition determination unit 301 determines that the target products classified as general goods and the target products classified as consumables that are subject to tax exemption among the purchased products are tax exempt based on the total amount of the products included in each category. Determine if the conditions are met.

Based on the tax exemption category code stored in the product information unit 331, the condition determination unit 301 determines whether the purchased product satisfies the conditions for tax exemption as a consumable item. That is, the condition determination unit 301 determines that the total amount (excluding tax) is 5,000 yen or more and 500,000 yen or less for the target product (consumable item) whose tax exemption classification code stored in the product information unit 331 is "01". determine if there is If the total amount is 5,000 yen or more and 500,000 yen or less, the condition determination unit 301 determines that the consumables meet the conditions for tax exemption. When the total amount is less than 5,000 yen and when the total amount exceeds 500,000 yen, the condition determination unit 301 determines that the consumables do not meet the conditions for tax exemption.

Also, the condition determination unit 301 determines whether the purchased product satisfies the conditions for tax exemption as a general product based on the tax exemption category code stored in the product information unit 331 . That is, the condition determination unit 301 determines whether the total amount (excluding tax) of the target product (general product) having the tax exemption classification code "02" stored in the product information unit 331 is 5,000 yen or more. do. If the total amount is 5,000 yen or more, the condition judgment unit 301 judges that the general article satisfies the conditions for tax exemption. If the total amount is less than 5,000 yen, the condition determination unit 301 determines that the general goods do not meet the conditions for tax exemption.

In addition, the condition determination unit 301 determines whether the total amount (not including the tax amount) of the target products included in the category of consumables exceeds the maximum amount (500,000 yen) of the conditions for tax exemption for consumables. .

The tax exemption processing unit 302 executes tax exemption processing for exempting the tax amount for the target product of the category determined by the condition determination unit 301 to satisfy the conditions for tax exemption. That is, the tax exemption processing unit 302 executes tax exemption processing for exempting, for example, the commodity tax for the target product of the category determined by the condition determination unit 301 to satisfy the conditions for tax exemption.

The designation determination unit 303 determines whether or not the target product of general goods has been designated by the designation unit (designation key K4). The designation determination unit 303 determines whether the designation key K4 has been operated for the purchased general merchandise.

The category change unit 304 changes the category of the target product determined to be designated by the designation determination unit 303 to the consumables category. The classification change unit 304 changes the classification code "02" stored in the commodity information unit 331 of the general goods determined to be designated by the designation determination unit 303 to "01", which is the consumables section. .

If the condition determination unit 301 determines that the consumable item exceeds the upper limit of the condition, the designation disabling unit 305 prohibits the change of classification to the consumable item. If the condition determination unit 301 determines that the consumable item exceeds the upper limit (500,000 yen) of the condition, the designation prohibition unit 305 disables the operation of the designation key K4, for example, and It is not possible to change the classification to When the condition determination unit 301 determines that the consumable item exceeds the upper limit (500,000 yen) of the condition, the designation disabling unit 305 disables the operation of the designation key K4, for example, and disallows the operation of the general item. It is not possible to change the classification to consumables.

The general product display section 306 displays target products classified as general products among the purchased products. The general goods display section 306 displays target goods classified as general goods among the purchased goods when the special packaging key K3 is operated.

From here, the control executed by the control unit 300 of the POS terminal 2 will be described. In the following embodiments, as an example, it is assumed that three products, product A, product M, and product N, are purchased. Merchandise A is classified as consumables with a tax exemption classification code of "01". Merchandise M and merchandise N are classified as general goods with a tax exemption classification code of "02". In addition, the price of the product A, the product M, and the product N in the embodiment is the tax-included price.

FIG. 7 is a flow chart showing the flow of control processing of the POS terminal. The control unit 300 determines whether the product code has been acquired based on the input from the code reader 40 (S11). If it is determined that the product code has been acquired (Yes in S11), the control unit 300 executes product sales registration processing based on product information obtained by searching the product master F1 based on the acquired product code. , the product information of the product (including the tax exemption classification code of the product) is stored in the product information section 331 (S12). Then, the control unit 300 returns to S11.

If it is determined that the product code has not been input (No in S11), the control unit 300 determines whether the closing key K1 provided on the keyboard 21 for declaring the end of the transaction has been operated. (S13). If it is determined that the closing key K1 has been operated (Yes in S13), the control unit 300 performs settlement processing for calculating the total amount, the amount of change, etc. for the transaction based on the product information stored in the product information unit 331. (S14). The settlement process executed in S14 is a settlement process for calculating the total amount including the amount of tax such as consumption tax imposed on the product purchased by the customer.

Then, the control unit 300 prints the product information, payment information, etc. of the product for which payment processing has been performed on a receipt paper to issue a receipt (S15). Then, the control unit 300 transmits product information (transaction number, transaction date and time, register number, product code, unit price, points, etc.) and payment information (total amount, tax amount, change amount, etc.) of the processed product to the server 4. (S16). Then, the control unit 300 returns to S11.

If it is determined that the closing key K1 has not been operated (No in S13), the control section 300 determines whether the tax exemption key K2 has been operated (S21). If it is determined that the operation has been performed (Yes in S21), the control unit 300 assumes that the tax exemption process has been declared and executes the tax exemption process shown in FIG. 8 (S22). Then, the control unit 300 returns to S11. If it is determined that the tax exemption key K2 has not been operated (No in S21), the control section 300 returns to S11.

Next, the tax exemption process executed at S22 will be described. FIG. 8 is a flow chart showing the flow of control processing related to the tax exemption processing of the POS terminal 2. As shown in FIG. As shown in FIG. 8, the control unit 300 drives the passport reader 41 to determine whether the passport information has been read (S31). It waits until it is read (No in S31), and when it is determined that the information on the passport has been read (Yes in S31), the control unit 300 selects consumables based on the product information stored in the product information unit 331. For classified target products and target products classified as general products, the total amount of the target products is calculated for each category (S32).

Next, the condition determination unit 301 classifies consumable goods and general goods based on the total amount calculated in S32 and the conditions for tax exemption of consumable goods and general goods stored in the tax exemption setting value file F3. , it is determined whether the conditions for tax exemption are met (S33). If the consumables and/or general goods meet the conditions for tax exemption (Yes in S33), the tax exemption amount is calculated for the category that satisfies the conditions (S34). Then, the control unit 300 displays a tax exemption confirmation screen that displays the total amount (excluding tax) for each category of consumable goods and general goods for the purchased target product (S35).

FIG. 9 is a diagram showing an example of the tax exemption confirmation screen G1. As shown in FIG. 9, the tax exemption confirmation screen G1 displays an area M1 for displaying information on general goods, an area M2 for displaying information on consumables, and an area M3 for displaying information on tax exemption amounts. The area M1 displays the total price (including tax) of the target products classified as general products. The area M1 displays a message as to how much more general goods must be purchased to meet the conditions for tax exemption as general goods. In the example of FIG. 9, it is displayed that the total price (including tax) of general goods (product M and product N) is 4000 yen. In addition, in the example of FIG. 9, a message is displayed indicating that if an additional 1,129 yen (excluding tax) worth of general goods is purchased, the conditions for tax exemption as general goods are met.

The area M2 displays the total amount (excluding tax) of the target products classified as consumables. The area M2 displays how much more consumables must be purchased to meet the conditions for tax exemption as consumables. In the example of FIG. 9, it is displayed that the total amount (including tax) of the consumables (product A) is 10000 yen. Also, in the example of FIG. 9, a message is displayed indicating that the consumables have already met the conditions for tax exemption.

An area M3 displays the sum of the tax exemption amount for general goods and the tax exemption amount for consumables. In the example of FIG. 9, general goods do not meet the conditions for tax exemption, but consumables meet the conditions for tax exemption. Therefore, the total tax exemption amount (741 yen) of the tax exemption amount for general goods (0 yen) and the tax exemption amount for consumables (741 yen) is displayed in the area M3.

The tax exemption confirmation screen G1 also displays a special packing key K3 and a tax exemption determination key K6.

Returning to the description of FIG. Next, the control unit 300 determines whether the tax exemption confirmation key K6 has been operated (S36). When it is determined that the tax exemption confirmation key K6 has not been operated (No in S36), the control section 300 determines whether the special packaging key K3 has been operated (S51). If it is determined that the special packaging key K3 has been operated (Yes in S51), the condition determination unit 301 determines that the total amount (excluding tax) of the target products classified as consumables is the maximum amount of the conditions for tax exemption ( 500,000 yen) is exceeded (S52). When the condition determination unit 301 determines that the upper limit of the conditions for tax exemption is not exceeded (No in S52), the general goods display unit 306 displays the target goods classified as general goods among the purchased goods and the designated goods. A package selection screen displaying the key K4 is displayed (S53).

FIG. 10 is a diagram showing an example of the package item selection screen G2 displayed by the general item display unit 306 in S53. As shown in FIG. 10, the package selection screen G2 includes an area M4 for displaying the product name of the purchased general item, an area M5 for displaying the unit price of the target item, and an area M5 for displaying the target item. a designation key K4 to change the classification of consumables, a non-designation key K7 operated when not changing to the consumables classification, and a confirmation key K5 for confirming the classification change from general goods to consumables. By operating the designation key K4, the operator changes the tax exemption category of the target product associated with the operated designation key K4 from general goods to consumables.

In the case of FIG. 10, product M and product N are displayed as target products of general products. In the case of the embodiment, the tax exemption categories of the products M and N are changed to consumables.

Returning to the description of FIG. When the condition determination unit 301 determines that the amount exceeds the upper limit of the conditions for tax exemption (Yes in S52), the general goods display unit 306 displays the target goods classified as general goods among the purchased goods. The selected package selection screen is displayed (S54). In the package selection screen displayed in S54, it is not possible to change the classification to consumables by the designation key K4 in the package selection screen G2. For example, in the package selection screen G2, the designated key K4 is grayed out and cannot be operated (the non-designated key K7 can be operated). Further, for example, even if the designation key K4 is operated on the package selection screen G2, no signal indicating that the designation key K4 has been operated is generated. Further, for example, even if the designation key K4 is operated on the package selection screen G2, the control unit 300 does not receive a signal indicating that the designation key K4 has been operated. The designation disabling unit 305 prohibits the designation unit from changing the classification to consumables in such a process, that is, when the condition determination unit 301 determines that the consumables exceed the upper limit of the conditions for tax exemption. Execute the process to be.

Next, the designation determination unit 303 determines whether the designation key K4 has been operated for the purchased general merchandise (S55). If the designation determination unit 303 determines that the designation key K4 has been operated for the purchased general merchandise (Yes in S55), then the control unit 300 determines whether the confirmation key K5 has been operated ( S56). If it is determined that the confirmation key K5 has been operated (Yes in S56), the category change unit 304 changes the target product stored in the product information unit 331 for the general product for which the designation key K4 has been operated. is changed from "02" to "01" (S57). Then, the control unit 300 returns to S32.

If the designation determination unit 303 determines in S55 that the designation key K4 has not been operated for the purchased general merchandise (No in S55), and if the decision key K5 has not been operated in S56. If so (No in S56), the controller 300 returns to S55. If it is determined in S51 that the special packaging key K3 has not been operated (No in S51), the control section 300 returns to S36.

If it is determined in S36 that the tax exemption confirmation key K6 has been operated (Yes in S36), the control section 300 confirms the tax exemption amount calculated in S34 (S37). Then, the control unit 300 displays a determination screen displaying a list of target products for which the tax exemption amount has been determined (S38).

FIG. 11 is a diagram showing an example of the confirmation screen G3 displayed in S38. As shown in FIG. 11, the confirmation screen G3 includes an area M6 for displaying the name of the target product subject to tax exemption, an area M7 for displaying the price of the target product, an area M8 for displaying the number of purchases of the target product, and an area M8 for displaying the number of target products purchased. area M9 for displaying the amount (for example, the amount obtained by subtracting the discount amount from the price of the target product), area M10 for displaying a mark indicating whether or not the conditions for tax exemption are met, area M11 for displaying the tax exemption amount, closing Display key K1.

In the case of the embodiment, in the area M10, the mark "TN" is displayed for general goods that meet the conditions for tax exemption. Consumable goods that meet the conditions for tax exemption are marked with a mark "TC". General goods that do not meet the conditions for tax exemption are marked with the mark “General”. Consumables that do not meet the conditions for tax exemption will be marked with a "cancel" mark.

In the example of FIG. 11, the area M10 displays a mark "TC" indicating that the product A, which is originally a consumable item, satisfies the conditions for tax exemption. Merchandise M and merchandise N are reclassified from general goods to consumable goods in the processing of S57 and satisfy the conditions for tax exemption, so both of them are displayed with the mark "TC" in the area M10. In this embodiment, since both the product M and the product N are changed from general goods to consumable goods, there is no indication of "TN", which is a mark of the target goods that meet the conditions for tax exemption as general goods. do not have.

Returning to the description of FIG. Next, the control unit 300 determines whether or not there is a correction declaration for the target product for which tax exemption has been confirmed in S37 (S39). For example, if you have not yet met the conditions for tax exemption and want to purchase new products to meet the conditions, or if the total amount of consumables (excluding tax) already exceeds 500,000 yen. Therefore, if the consumable goods are excluded from the target and the price is set to 500,000 yen or less, a correction is declared and the correction process is executed. The declaration of correction operates, for example, a correction key (not shown).

If it is determined that a correction declaration has been made (Yes in S39), the control unit 300 performs correction processing to add or remove the designated product from the target products (S44). Then, the process returns to S32, and it is determined whether the condition is satisfied again in S33.

If it is determined that there is no declaration of correction (Yes in S39), the control section 300 determines whether the closing key K1 has been operated (S40). The system waits until it is determined that the close key K1 has been operated (No at S40), and when it is determined that the close key K1 has been operated (Yes at S40), the settlement process for the transaction is executed (S41). In the settlement process of S41, the tax exemption processing unit 302 executes the tax exemption process of exempting the commodity tax described in the area M11, for example, based on the tax exemption amount determined in S37.

Next, the control unit 300 issues a receipt on which product information and payment information are printed for the product for which payment has been processed (S42). The control unit 300 then transmits the product information and payment information of the transaction to the server 4 . Then, the control unit 300 ends the tax exemption process and returns to S11.

According to such an embodiment, it is possible to efficiently change the classification of general goods to the classification of consumables.
