Description

  The present invention relates to a product sales data processing device, a program, and a product sales data processing system.

Reduced tax rates may apply under the consumption tax system. The reduced tax rate is a tax rate that is set lower than the standard tax rate according to the nature of the product (including services), such as setting a tax rate lower than the standard tax rate for products such as daily necessities. .
The above reduced tax rates are not uniform, and different tax rates may be applied depending on, for example, the characteristics of each product. That is, in the consumption tax system, a tax rate applied to a product may be different.
Therefore, based on the tax rate setting information that associates tax classifications and tax rates classified by product purchase format, the product tax rate is specified according to the specified product purchase format, and based on the specified tax rate. There is known a merchandise sales data processor configured to calculate a tax amount on merchandise (for example, see Patent Document 1).
In addition, based on the tax rate setting information that associates tax classifications and tax rates classified by product sales points, the product tax rate is specified according to the sales points of the specified product, and the specified tax rate is determined based on the specified tax rate. There is known a product sales data processing device for calculating a tax amount on a product (for example, see Patent Document 2).

In applying the reduced tax rate, a refund system may be adopted when purchasing goods at stores. The refund scheme is to pay the standard tax rate, including products to which the reduced tax rate is applied, and then to return the excess amount paid to the consumer to the products to which the reduced tax rate is applied. It is.
In the case of using the above refund system, personal numbers (my numbers) that are uniquely assigned to each citizen may be used. In other words, when purchasing a product, the consumer's personal number and the refund corresponding to the product to which the reduced tax rate is applied are managed in association with each other, and the refund is given to the consumer who presented the relevant personal number. Things.

If the refund system using personal numbers is introduced as described above, the POS register (product sales data processing device) of the store, for example, will apply a reduced tax rate to any product in one transaction (shopping). It is required that consumers, store staff, and the like can accurately grasp information on the refund, such as the amount of the refund for the product.
However, for example, the merchandise sales data processing devices described in Patent Literature 1 and Patent Literature 2 are designed to appropriately calculate the tax amount corresponding to different tax rates according to the conditions at the time of purchase for each product. I have. That is, the merchandise sales data processing devices described in Patent Literature 1 and Patent Literature 2 do not consider the refund system. For this reason, it is difficult for the merchandise sales data processing devices described in Patent Literature 1 and Patent Literature 2 to appropriately grasp information on refunds.

  The present invention has been made in view of such circumstances, and when a refund system using a personal number is adopted under a consumption tax system to which a reduced tax rate is applied, information on a refund is accurately provided. The purpose is to be able to grasp.

FIG. 4 is a block diagram illustrating a configuration example of the POS register 1. In the figure, blocks corresponding to the configuration shown in FIG. 2 are denoted by the same reference numerals, and description thereof will be omitted.
As shown in FIG. 1, the POS register 1 includes a CPU (Central Processing Unit) 11, a storage unit 12, a RAM (Random Access Memory) 13, a display unit with a touch panel 14, a key operation unit 15, a display unit 16 for customers, It includes a change machine 17, a reader section 18, a printing section 19, a communication section 20, and a drawer 30.
The CPU 11, the storage unit 12, the RAM 13, the display unit with a touch panel 14, the key operation unit 15, the display unit 16 for the customer, the automatic change machine 17, the reader unit 18, the printing unit 19, the communication unit 20, and the drawer 30 are connected to an internal bus and a communication unit. Each is connected via a wire.

  The communication unit 20 communicates with the higher-level device 100 of the POS register 1, for example.

  The storage unit 12 stores programs to be executed by the CPU 11, image data to be displayed on the display unit 14 with a touch panel, and the like.

  The RAM 13 is a memory that expands programs and work areas read from the storage unit 12. The RAM 13 stores, for example, a product master or the like as information on the product taken from the store controller.

FIG. 5 shows an example of a product master (product management information) stored in the RAM 13 of the POS register 1. The product master stores information on each product.
The product master shown in the figure has a structure in which information such as a product name, a unit price, and a refund rate is associated with a product code for each product, for example.

  The product code is an identifier (number) uniquely assigned to each product. The product name is the name of the product. The unit price is a price per one corresponding product (or a predetermined unit quantity).

The refund rate is the highest rank stored according to the adoption of the refund system under the consumption tax system, and indicates the refund rate when the corresponding product is purchased at the standard tax rate.
In the drawing, an example is shown in which the refund rate of the product A and the product B is 0%, the refund rate of the product C and the product D is 2%, and the refund rate of the product E is 5%. The refund rate is the difference between the reduced tax rate and the standard tax rate. Therefore, a standard tax rate is set for the products A and B having a refund rate of 0%. In addition, for the products C and D whose refund rates are 2%, reduced tax rates are set by subtracting 2% from the standard tax rates. In addition, a reduced tax rate, which is obtained by subtracting 5% from the standard tax rate, is set for the commodity E whose refund rate is 5%.
As a specific example, the reduced tax rate of the products C and D when the standard tax rate is 10% is 8%. For this reason, if the product C or the product D is purchased at the standard tax rate at the time of purchase, the amount obtained by subtracting the tax-included amount at the 8% tax rate from the tax-included amount at the 10% tax rate (ie, 2% of the foreign tax price). Is a refund.
For example, instead of the refund rate, a reduced tax rate of the corresponding product may be stored. In this case, the refund rate is obtained by subtracting the reduced tax rate from the standard tax rate.

  FIG. 6 shows an example of a receipt issued by the POS register 1 in response to purchase of a product at the store ST. The receipt shown in the figure corresponds to the case where the standard tax rate is 10% and the product master shown in FIG.

The receipt result area AR1 of the receipt shown in FIG. 5 indicates that, among the products shown in the product master of FIG. 5, four products A, two products C, and one product E have been purchased. ing.
In addition, the tax-included price for each product is shown in the accounting result area AR1. Under the refund system, at the time of purchase, products subject to reduced tax rates are also subject to the standard tax rate.
According to the product master in FIG. 5, the unit price of the product A is 100 yen, and the tax-included price of the four products A at the standard tax rate is 440 yen. Further, since the unit price of the product C is 300 yen, the tax-included price of the two products C at the standard tax rate is 660 yen. Further, since the unit price of the product E is 100 yen, the tax-included price of one product E at the standard tax rate is 110 yen.
In this case, the total price of four products A, two products C, and one product E is 1210 yen. Here, it is shown that the deposit is 2,000 yen and the change is 790 yen due to the customer depositing 2,000 yen for payment for the total amount of 1210 yen.

According to the product master of FIG. 5, among the products A, C, and E shown in the receipt of FIG. 6, the product A is a product to which the standard tax rate is applied, and the products C and E have reduced tax rates. It is an applicable product. Therefore, in the transaction result area AR1 of the receipt, a mark indicating that the reduced tax rate is applied is shown on the left side of the product name for the products C and E to which the reduced tax rate is applied. As described above, in the receipt, whether or not the product is eligible for the reduced tax rate can be distinguished for each product based on the presence or absence of the asterisk added to the product name.
In the figure, the mark indicating that the reduced tax rate is applied is an asterisk, but another mark may be used.

Further, in the refund message area AR2 under the accounting result area AR1, a message to the effect that the products marked with asterisks are the products to which the reduced tax rate is applied and the reduced tax rate is refunded is printed.
In the accounting result area AR1, the refund amount is indicated for each of the products C and E to which the reduced tax rate is applied. The refund amount corresponding to two products C is 12 yen, and the refund amount corresponding to one product E is 5 yen. Since the product A is a product to which the standard tax rate is applied, the refund amount column indicates that there is no refund. In the figure, a horizontal line indicates that there is no refund. In indicating that there is no refund, for example, "0 (yen)" may be described.
Then, in the accounting result area AR1, the total refund amount in this transaction is also shown. In this case, the total refund amount is 17 yen, which is the sum of the refund amount of 12 yen corresponding to two products C and the refund amount of 5 yen corresponding to one product E.

Further, under the refund system supported by the present embodiment, the upper limit of the refund for a certain period (for example, one year) is specified. For example, if the sum of the reimbursed sums of products that have been applied in a year and the reduced tax rate is applied simply exceeds the upper limit, only the reimbursement will be made up to the upper limit and no further refund will be received. That is. When the upper limit of the refund is specified in this way, the consumer wants to know whether or not the accumulated amount of the refund has reached the upper limit.
Therefore, in the receipt of the present embodiment, a total refund amount information area AR3 for notifying the consumer of whether the total refund amount up to the present has reached the upper limit amount is provided. In the refund accumulation information area in FIG. 7, the total refund amount for the current year up to the current shopping and the upper limit amount are shown. The consumer can see at a glance whether or not the accumulated refund amount exceeds the upper limit amount by looking at the accumulated refund amount information area AR3.
If the total refund amount exceeds the upper limit amount, the total refund amount information area AR3 indicates not only the total refund amount and the upper limit amount but also exceeds the upper limit amount. A message notifying the consumer of the fact may be displayed. As an example of such a message, for example, a sentence having a content such as “the cumulative total of the refund amounts has exceeded the upper limit amount” can be included in the total refund amount information area AR3.

Further, under the refund system corresponding to the present embodiment, in order to receive a refund, it is necessary to present a personal number when purchasing a product. Specifically, a customer who intends to purchase a product to which the reduced tax rate is applied presents a personal number to a clerk operating the POS register 1. The clerk inputs the personal number presented by the customer into the POS register 1. As a mode of inputting a personal number, for example, a clerk may look at a personal number card or the like presented by a customer and input a numerical value of the personal number printed on the personal number card by key operation or the like. Further, an operation of reading the personal number stored in the IC chip provided in the personal number card by the reader / writer of the reader unit 18 may be performed. Alternatively, when a personal number is described on a personal number card by a bar code or a two-dimensional code, the personal number is input by reading the bar code or the two-dimensional code of the personal number card by the code reader of the reader unit 18. It is possible.
By inputting the personal number in this manner, the POS register 1 associates the information on the refund for each product to which the reduced tax rate is applied in the settlement process with the personal number, and transmits the information to the refund management server 200. be able to.

In response to the input of the personal number in this manner, the POS register 1 of the present embodiment prints the input personal number on a receipt. That is, in the receipt of FIG. 6, a personal number area AR4 is provided, in which the personal number input corresponding to the current transaction is shown.
However, since the personal number is important personal information, it may not be preferable to display the numerical values of all digits. Therefore, in the present embodiment, as shown in the figure, only some of the digits of the personal number are shown, and other digits are replaced with characters such as "X". And mask (conceal) them.

  The number of digits to be masked for the personal number printed in the personal number area AR4 may be set by operating the POS register 1. Further, whether or not the personal number area AR4 itself should be provided may be set. Alternatively, the personal number may be encrypted by a predetermined encryption algorithm, and the coded value may be printed in the personal number area AR4.

  In the present embodiment, the receipt as described above is issued (that is, the information regarding the refund amount is output), so that, for example, the customer, who is a consumer, Yes, it is possible to determine whether the cumulative total of the refunds has reached the upper limit. In other words, information on the refund can be accurately grasped.

In the receipt, whether or not the reduced tax rate is to be applied may be distinguished for each product by an aspect other than the mark.
Specifically, for example, in the columns indicating the products and quantities in the receipt result area AR1 of the receipt, products that are not eligible for the reduced tax rate, such as "standard tax rate products" and "products to which the reduced tax rate is applied", and the application of the reduced tax rate Print the item name that distinguishes it from the target product. Then, in the area corresponding to the “standard tax rate product”, the product name and the number of purchases are printed for each product among the purchased products that are not applicable to the reduced tax rate, and the purchase price is printed in the area corresponding to the “product with the reduced tax rate applied”. For each product to which the reduced tax rate is to be applied, a line with the product name and the number of purchases is printed. As described above, even if the products to which the reduced tax rate is not applied and the products to which the reduced tax rate is applied are divided on a region basis, the two are clearly distinguished.

Subsequently, an example of a processing procedure executed by the POS register 1 in accordance with the accounting of one transaction including the purchase of a product to which the reduced tax rate is applied will be described with reference to the flowchart of FIG.
Step S101: As described above, when the consumer receives a refund in accordance with the purchase of a product to which the reduced tax rate is applied under the refund system supported by the present embodiment, the consumer (customer) Needs to present a personal number to the store when purchasing a product.
Therefore, the customer presents his / her personal number when having the clerk at the POS register 1 check the purchased merchandise. For this purpose, for example, the customer gives his personal number card to the clerk. The clerk can read the personal number from the IC card by the reader / writer of the reader unit 18 if the personal number card provided by the customer has an IC card in which the personal number is recorded. If the personal number code is printed on the personal number card given by the customer, the code number of the reader unit 18 reads the personal number as a code. In addition, if the personal number card given by the customer does not have an IC chip and the code is not printed, the store clerk can input a numerical value for each digit of the personal number written on the personal number card, for example, An operation of setting the number is performed by operating the key operation unit 15.
The POS register 1 inputs the personal number read by the reader / writer or the personal number input by the numeral as described above.

When inputting the personal number, for example, a function key for declaring the input of the personal number (that is, a declaration of the application of the refund) is provided on the product registration screen, and the POS is operated in response to the operation of the function key. The register 1 may be set to a state in which the input of the personal number can be accepted.
For the POS register 1, for example, as for the method of inputting the personal number, one of the reading by the reader / writer and the input by the number is made valid, or both are made valid. The setting by operation may be made possible.

  Step S102: After the personal number is input, the POS register 1 waits for a product registration operation to be performed. The product registration operation is an operation of inputting a product code of a product corresponding to a certain item, and an operation of inputting a purchase quantity. That is, depending on the product registration operation, an item as a product and the number of purchased products of the corresponding item are specified.

  Step S103: When the product registration operation is performed, the POS register 1 stores the current product, the product code specified by the recording operation, and the purchase quantity in association with each other to be included in the settlement information. As a result, the registration of one product in the current transaction is performed.

Step S104: Next, the POS register 1 determines whether or not the product registered in step S103 is a product to which the reduced tax rate is applied. This determination can be made by, for example, referring to the product master (FIG. 5) and determining whether the refund rate associated with the same product code as the registered product is greater than 0%.
Step S105: If it is determined in step S104 that the product is a product to which the reduced tax rate is to be applied, the POS register 1 calculates a refund amount for the product registered in step S102. To calculate the refund amount K, the unit price indicated by the product master for the registered product is T, the number of purchases specified in the product registration operation is N, and the refund rate indicated by the product master for the registered product is R (for example, If it is 2%, it is determined as R = 0.02) by the following equation. Here, the unit price T, the purchase quantity N, and the refund rate R are examples of refund amount calculation information.
K = T × N × R
Then, the POS register 1 calculates the refund amount K calculated in accordance with the current product registration operation as described above with the total refund amount obtained in accordance with the registration of the product to which the reduced tax rate has been applied in the current transaction. To be integrated.
The refund amount of the registered product calculated in step S105 and the total refund amount updated by the integration are included in the settlement information.

Step S106: If it is determined in step S104 that the product registered this time is not applicable to the reduced tax rate, or after the processing in step S105, the POS register 1 determines whether or not a subtotal operation has been performed.
If it is determined that the subtotal operation is not performed, the POS register 1 returns the process to step S102. Good for this, the product registration process corresponding to the product registration operation under the same transaction is subsequently performed. In addition, every time registration is performed for a product to which the reduced tax rate is applied, calculation of the refund amount and accumulation of the total refund amount are performed.

  Step S107: If it is determined in step S106 that the subtotal operation has been performed, the POS register 1 performs the settlement process using the settlement information in which the result of the product registration so far is reflected. The clerk performs operations related to settlement using the cash, credit card, and electronic money received from the customer, and the POS register 1 performs settlement processing according to the use of the cash, credit card, electronic money, and the like.

Step S108: When the settlement process is completed, the POS register 1 sends the refund information on the refund obtained in accordance with the product to which the reduced tax rate is applied in the current transaction through the higher-level device 100 to the refund management server. 200. The refund information is, for example, information in which the total refund amount finally obtained in step S105 corresponding to the current transaction is associated with the personal number input in step S101. In addition, the refund information may include, for example, information on a refund amount for each product to which the reduced tax rate is applied in this transaction.
The refund management server 200 manages refund management information in association with each personal number. The refund management server 200 updates the refund management information associated with the same personal information included in the received refund information using the received refund information. At this time, the total refund amount included in the refund management information is updated by adding up the total refund amount included in the received refund information. If the refund information includes information on the refund amount for each product subject to the reduced tax rate purchased in this transaction, such information is added to the refund management information.

Step S109: Next, the POS register 1 acquires the current total refund amount corresponding to the customer of this transaction. For this purpose, the POS register 1 transmits the refund amount accumulation request including the personal number input in step S101 to the refund management server 200 via the host device 100.
The refund management server 200 searches the refund management information associated with the same personal number included in the received refund amount accumulation request, and returns the refund management information included in the searched refund management information. The accumulated amount of money is transmitted to the POS register 1 of the request source. The POS register 1 acquires the received total refund amount.
The total refund amount acquired in this manner reflects the total refund amount corresponding to the current transaction based on the refund information transmitted in step S108. However, if the total refund amount obtained in this transaction is not reflected in the acquired total refund amount due to time lag, etc., the refund amount corresponding to this transaction will be added to the total refund amount acquired in the POS register 1. The sum may be added. As a result, a total refund amount reflecting the total refund amount according to this transaction is obtained.

Step S110: Next, the POS register 1 prints and issues a receipt indicating the accounting result in the current transaction by the printing unit 19. As illustrated in FIG. 6, in the receipt issued in this manner, in the accounting result area AR1, products to which the reduced tax rate is applied and products to which the reduced tax rate is not applied are distinguished by, for example, the presence or absence of an asterisk. , The refund amount for each product and the total refund amount are shown.
A refund message area AR2 is provided on the receipt, and a message related to the refund is printed. The receipt also has a total refund amount information area AR3, on which the total refund amount and the upper limit are printed. Further, a personal number area AR4 is provided on the receipt, and the personal number input in step S101 is printed.

The refund of the refund in the present embodiment is provided on condition that a personal number is presented at the time of purchasing a product to which the reduced tax rate is applied. For this reason, if the personal number is not provided, the general tax rate will be applied uniformly and no refund will be incurred even if the product subject to the reduced tax rate is purchased.
As the receipt issued in this case, for example, the refund amount for each product in the accounting result area AR1 and the total refund amount are not printed. Further, an asterisk for distinguishing a product to which the reduced tax rate is applied from a product not to be applied in the same accounting result area AR1 may or may not be printed. The refund message area AR2, the refund amount total information area AR3, and the personal number area AR4 may not be printed.

  Also, in the process of FIG. 10, an example is shown in which a personal number is input in a stage before registration of a product in order to receive a refund. However, for example, the personal number may be input at a predetermined stage or an arbitrary stage until the settlement is completed. For example, if a personal number is entered during product registration and a declaration to receive a refund is made, if any of the products registered so far are eligible for the reduced tax rate, At this stage, the refund amount for the product may be calculated.

  Also, the acquisition of the total refund amount from the refund management server 200 may be performed at a stage before the settlement process is completed, for example, after the personal number is input. In this case, since the total refund amount according to this transaction is not reflected in the accumulated refund amount, the POS register 1 adds the total refund amount to the acquired accumulated refund amount. The total amount of money may be printed in the total refund amount information area AR3.

Hereinafter, a modified example of the present embodiment will be described.
[First Modification]
The refund system supported by this embodiment is applied only to individuals, not to corporations (here, including sole proprietors). Receipts (receipts) are used by corporations as proof of expenses, and are not used by individuals.
Therefore, the POS register 1 of the present embodiment is configured not to issue a receipt in accordance with a transaction involving presentation of a personal number. This prevents a receipt from being issued by mistake when an individual purchases a product to which the reduced tax rate is applied.
Specifically, for example, when the personal number corresponding to the declaration of the application of the refund is input in the accounting (processing from product registration to settlement) corresponding to one transaction, the POS register 1 issues a receipt, for example. Even if the operation of instructing is performed, the operation is invalidated and a receipt is not issued. In this way, if the personal number corresponding to the declaration of the application of the refund is entered, the issuance of the receipt is prohibited. At this time, for example, a message indicating that a receipt cannot be issued because the transaction is an individual transaction may be displayed on the display unit 14 with a touch panel.
For example, if a product that is eligible for the reduced tax rate and a product that is not eligible for the reduced tax rate are purchased in combination, a receipt corresponding to the total number of products that are not eligible for the reduced tax rate will be issued. It may be.

[Second Modification]
In addition, for the transaction for which the personal number has been input, the transaction information can be stored in association with the input personal number. The accounting information may be stored in the POS register 1. For example, it is preferable that the accounting information collected from the POS registers 1 by the host device 100 be integrated and managed.
By managing the accounting information in this way, for example, it is possible to output the purchase results of each customer using the personal number. As an output form of the purchase result, for example, it may be printed on a sheet as a report or the like, or may be output by display. In outputting the purchase result, the result total period may be specified, for example, in units of days, hours, months, first half, second half, and year.
Further, as the above-mentioned purchase results, for example, the purchase results of only the products to which the reduced tax rate is applied may be output. The purchase results of only the products to which the reduced tax rate is applied include, for example, a refund amount or a total refund amount for each purchased product to which the reduced tax rate is applied.

[Third Modification]
In addition, by managing personal numbers presented to receive refunds in association with, for example, customer membership numbers at stores, there is a possibility that useful services related to refunds can be provided to customers. is there.
However, since the personal number is important personal information, it is not preferable that the store uses the personal number without permission of the customer. Therefore, for example, when a customer presents a personal number for the first time at a store, a dialog for allowing the customer to set whether or not to use the personal number as personal information at the store is displayed on the customer display unit. 16 can be displayed. In this dialog, for example, a message such as "Are you sure you want to use your personal number to improve service at the store?" In this case, the display unit 16 for a customer is a display unit with a touch panel. In the dialog, in addition to the above-mentioned message, buttons of “Yes” and “No” are arranged.
The customer who sees the dialog operates the “Yes” button in the dialog if he / she accepts the use of the store's personal number. Thereby, the personal number input this time is managed so as to be associated with the member number of the customer in the member information stored in the higher-level device 100, for example. The member number is also presented from the customer to the clerk by a member card or the like at the time of accounting.
On the other hand, if the customer does not want the store to use the personal number, he operates the "No" button. As a result, the personal number is not associated with the member number.
Regardless of whether or not the customer has accepted the use of the personal number, it is troublesome for the customer to display such a dialog even when the personal number is presented in the next shopping. There is. Therefore, in response to displaying the dialog, a flag indicating that the dialog has been displayed is set in association with the member number of the customer. Then, when the member number and the personal number are presented thereafter, if the flag is set corresponding to the presented member number, the dialog is not displayed. Thereby, the dialog can be displayed only when the customer presents the personal number first.
