Description

Embodiments of the present invention relate to an information processing device, an information processing program, and an information processing method.

In payments relating to commercial transactions, multiple tax types such as "tax-inclusive method, tax rate 8%,""tax-inclusive method, tax rate 10%,""tax-exclusive method, tax rate 8%," and "tax-exclusive method, tax rate 10%" may be applied to multiple products in a single transaction.
On the other hand, as payment methods become more diverse, the payment amount of one transaction may be divided among several payment methods. For example, the remaining amount after applying discounts from point services may be paid in cash. Or, when the balance of a prepaid card is insufficient to cover the payment amount, the remaining amount may be paid by prepaid card and the remaining amount may be paid by electronic money.

In tax processing, the processing method may differ depending on the payment method. In such a case, tax processing becomes very complicated for a transaction in which multiple products with different taxation types are mixed and the payment amount is shared among multiple payment methods.
For these reasons, it was desirable to simplify tax treatment in such situations.

An example of an embodiment will be described below with reference to the drawings. Note that in this embodiment, a point-of-sale (POS) terminal device having a function as an information processing device will be described as an example.
FIG. 1 is a block diagram showing the main circuit configuration of a POS terminal device 100 according to this embodiment.
The POS terminal device 100 performs processing for selling products to customers in a store.

The POS terminal 100 is a so-called face-to-face type, and is mainly operated by store clerks. The POS terminal 100 is installed inside the store facing the workspace for store clerks. Customers usually wait in a waiting space that is set up separately from the workspace. Therefore, in the following, the workspace side and waiting space side will be referred to as the store clerk side and customer side, respectively, based on the POS terminal 100.

The POS terminal device 100 includes a processor 1, a main memory unit 2, an auxiliary memory unit 3, a store clerk touch panel 4, a keyboard 5, a fixed scanner 6, a handheld scanner 7, a credit card reader 8, a proximity communication unit 9, a card reader/writer 10, a receipt printer 11, a change unit 12, a customer touch panel 13, a communication unit 14, and a transmission path 15. The processor 1, the main memory unit 2, the auxiliary memory unit 3, the store clerk touch panel 4, a keyboard 5, a fixed scanner 6, a handheld scanner 7, a credit card reader 8, a proximity communication unit 9, a card reader/writer 10, a receipt printer 11, a change unit 12, a customer touch panel 13, and a communication unit 14 are connected to the transmission path 15.

The processor 1, main memory unit 2, and auxiliary memory unit 3 are connected via a transmission line 15 to constitute a computer for executing information processing relating to the control of the POS terminal 100.
The processor 1 corresponds to the central part of the computer. The processor 1 controls each part of the POS terminal 100 to realize various functions of the POS terminal 100 by executing information processing based on information processing programs such as an operating system, middleware, and application programs stored in the main storage unit 2 and the auxiliary storage unit 3.

The main memory unit 2 corresponds to the main memory portion of the computer. The main memory unit 2 includes a non-volatile memory area and a volatile memory area. The main memory unit 2 stores the above-mentioned information processing program in the non-volatile memory area. The main memory unit 2 may also store data required for the processor 1 to execute various information processes in the non-volatile or volatile memory area. The main memory unit 2 uses the volatile memory area as a work area where data is appropriately rewritten by the processor 1.

The auxiliary memory unit 3 corresponds to the auxiliary memory portion of the computer. The auxiliary memory unit 3 includes well-known storage devices such as an EEPROM (electrical erasable programmable read-only memory), a HDD (hard disk drive), or an SSD (solid state drive). The auxiliary memory unit 3 stores data used by the processor 1 in performing various information processing operations, and data generated by the processing in the processor 1. The auxiliary memory unit 3 may also store the information processing programs. A part of the storage area of the auxiliary memory unit 3 is used as a setting table TA. The setting table TA is a data table that records various user settings related to the operation of the POS terminal device 100. The setting table TA may be stored in the main memory unit 2.

The store clerk-side touch panel 4 is provided facing the store clerk. The store clerk-side touch panel 4 displays a screen for presenting information to the store clerk. The store clerk-side touch panel 4 also inputs instructions by the store clerk touching the screen.
The keyboard 5 has many keys for easy operation by the store clerk from the store side. The keyboard 5 inputs instructions by the store clerk by pressing these keys.

The fixed scanner 6 has a reading window facing the store clerk. The fixed scanner 6 captures an image of a product held in front of the reading window, and recognizes barcode information represented by the barcode formed on the product through image processing. The fixed scanner 6 then outputs the image to the processor 1. Note that the fixed scanner 6 may also be another type of well-known device that optically reads barcodes using reflection of laser light. The fixed scanner 6 may also be a well-known device that has a function of identifying a product using object recognition technology from an image of the product itself obtained by capturing an image of the product.
The handy scanner 7 is held by a store clerk and optically reads a barcode placed in front of a reading port of the handy scanner 7. The handy scanner 7 outputs barcode information represented by the read barcode to the processor 1.

The credit card reader 8 reads card information from a credit card.
The near-field communication unit 9 performs near-field wireless communication with a wireless tag that has come into close proximity to obtain data stored in the wireless tag. The near-field communication unit 9 also writes arbitrary information to the wireless tag through the near-field wireless communication.
The card reader/writer 10 reads card data recorded on predetermined cards such as membership cards and prepaid cards, etc. The card reader/writer 10 also writes any data onto the membership cards.

The receipt printer 11 prints an image of a receipt, invoice, sales slip, or other certificate on receipt paper. The receipt printer 11 discharges the receipt paper with the image printed thereon to the outside through a receipt discharge port.
The change unit 12 counts the value of coins inserted through the coin insertion slot and stores them in an internal storage. The change unit 12 discharges coins stored in the storage slot to a coin tray through the coin discharge port. The change unit 12 counts the value of banknotes inserted through the banknote insertion slot and stores them in an internal storage. The change unit 12 discharges banknotes stored in the storage slot from the banknote discharge port. The banknote discharge port holds the discharged banknotes with a portion of them exposed to the outside.
The customer-side touch panel 13 is provided facing the customer side. The customer-side touch panel 13 displays a screen for presenting information to the customer. The customer-side touch panel 13 also inputs instructions by touching the screen by the customer.

The communication unit 14 performs communication processing for the processor 1 to send and receive various data to and from any device, such as a POS server, via the communication network 200. A LAN (local area network) is typically used as the communication network 200. However, in addition to a LAN, the Internet, a VPN (virtual private network), a public communication network, a mobile communication network, etc., can also be used as the communication network 200, either alone or in appropriate combination. A well-known device conforming to the communication method of the communication network 200 can be used as the communication unit 14.
The transmission path 15 includes an address bus, a data bus, a control signal line, etc. The transmission path 15 transmits data and signals exchanged between each unit connected thereto.

The basic hardware of the POS terminal 100 may be, for example, the hardware of another existing POS terminal. In this case, the transfer of the POS terminal 100 is generally performed in a state in which an information processing program describing the information processing described below is stored in the main storage unit 2 or the auxiliary storage unit 3. However, the hardware of the POS terminal 100 and the information processing program may be transferred separately in a state in which the above-mentioned information processing program is not stored in the main storage unit 2 or the auxiliary storage unit 3. Then, the information processing program may be written in the main storage unit 2 or the auxiliary storage unit 3 in response to an operation by an administrator of the POS terminal 100, etc. Alternatively, the hardware of the POS terminal 100 and the above-mentioned information processing program may be transferred separately in a state in which an information processing program other than the above-mentioned information processing program is stored in the main storage unit 2 or the auxiliary storage unit 3. Then, the separately transferred information processing program may be written in the main storage unit 2 or the auxiliary storage unit 3 in a form that replaces the information processing program already stored therein. The information processing program can be transferred by recording it on a removable recording medium such as a magnetic disk, magneto-optical disk, optical disk, or semiconductor memory, or by communication via a network.

Next, the operation of the POS terminal 100 configured as above will be described.
When the operating mode of the POS terminal 100 is set to a mode for setting various operating conditions, the processor 1 accepts instructions from the operator regarding the setting items and setting contents, and updates the setting table TA in accordance with the instructions. The setting items that can be set at this time are enable/disable of detail printing and full printing/specified printing. Detail printing refers to printing of tax details, which will be described later, on receipts. Full printing refers to printing tax details on all receipts. Specified printing refers to printing of tax details on receipts only if printing is specified.

When the POS terminal 100 is started up in the registration and settlement mode, the processor 1 performs the information processing described below in accordance with an information processing program stored in the main storage unit 2 or the auxiliary storage unit 3 .
2 and 3 are flow charts of information processing by the processor 1. Note that the contents of the processing described below are merely examples, and it is possible to change the order of some of the processing, omit some of the processing, or add other processing as appropriate. For example, the processor 1 executes various information processes for various functions that are realized in other existing POS terminal devices not described below, but only the information processes related to the characteristic functions of this embodiment are illustrated and described below.

In ACT 1, the processor 1 checks whether or not it is the start of registration. If the processor 1 cannot determine that it is the start of registration, it determines NO and proceeds to ACT 2.
In ACT 2, the processor 1 checks whether or not a recall instruction for a past transaction has been issued. If the processor 1 cannot confirm the instruction, it determines NO and returns to ACT 1.
Thus, in ACT1 and ACT2, the processor 1 waits for registration to start or for a callback to be instructed.

In response to a request from a customer, the store clerk starts a predetermined operation for registering the product that the customer wishes to purchase as a product to be traded. In response to this, the processor 1 determines YES in ACT 1 and proceeds to ACT 3.
As ACT 3, the processor 1 executes a registration process. The registration process is a process for registering the product that the customer is about to purchase as a product that is the subject of the transaction in response to an operation by a store clerk. The registration process may be, for example, a process similar to a process performed by another existing POS terminal device. Note that the products that are the subject of registration in the registration process may include products with different tax types. In this embodiment, one of "tax-inclusive method, tax rate 8%", "tax-inclusive method, tax rate 10%", "tax-exclusive method, tax rate 8%", "tax-exclusive method, tax rate 10%" and "non-taxable" is applied to each product.

As ACT4, the processor 1 executes accounting processing. The accounting processing is processing for calculating the payment amount for the products registered as the subject of the transaction and having the customer pay the payment amount. The payment processing may be, for example, processing similar to processing performed by another existing POS terminal device. The payment method used in the payment processing is a plurality of various payment methods such as cash payment, credit card payment, debit card payment, electronic money payment, code payment, carrier payment, point payment, or voucher payment. Furthermore, it is also possible to divide the payment amount for one transaction and settle it among a plurality of payment methods. Thus, by the processor 1 executing information processing based on the information processing program, the computer with the processor 1 as its central part functions as a payment means.
When the processor 1 completes the settlement, it transmits journal data including the details of the current transaction and the settlement result to a POS server (not shown) from the communication unit 14 over the communication network 200. The journal data is stored in the POS server. The processor 1 may temporarily store the journal data in the main memory unit 2 or the auxiliary memory unit 3, and transmit the journal data for multiple transactions together to the POS server.

On the other hand, if the store clerk needs to call back a past transaction, he/she instructs the call back by a predetermined operation. In response to this, the processor 1 judges YES in ACT2 and proceeds to ACT5.
In ACT 5, the processor 1 performs a call-back process. The call-back process is, for example, a process for responding to a customer's request for return. The call-back process is, for example, a process for reissuing a receipt. The type of process to be performed as the call-back process and the specific manner in which the process is performed are arbitrary and can be determined, for example, by the designer of the POS terminal 100.
In ACT 6, the processor 1 checks whether the callback process has caused the printing of a receipt to be required. If receipt printing is not required, the processor 1 determines NO and returns to the standby state of ACT 1 and ACT 2.

When the processor 1 completes the transaction processing in ACT 4, or if the processor 1 judges YES in ACT 6 because a receipt needs to be printed because the transaction has been corrected due to a return or because a request has been received to reissue the receipt, the processor 1 proceeds to ACT 7 in FIG. 3.
In ACT 7, the processor 1 checks whether or not tax types are mixed for the products that are the subject of the transaction registered in ACT 3 or the products that are the subject of the transaction that was the subject of the recall process in ACT 5. Then, for example, if the tax types applied to at least two of the subject products are different from each other, the processor 1 determines YES and proceeds to ACT 8.

In ACT 8, the processor 1 checks whether multiple payment methods were used in combination in the payment of the transaction that was the subject of the payment process in ACT 4 or the recall process in ACT 5. Then, for example, if multiple payment methods were used in the transaction, the processor 1 determines YES and proceeds to ACT 9.
In ACT 9, the processor 1 checks whether detailed statement printing is enabled. For example, the processor 1 refers to the setting table TA, and if "enabled" is recorded as the detailed statement printing setting, the processor 1 judges the result to be YES and proceeds to ACT 10.
Thus, the processor 1 proceeds to ACT 10 when mixed tax types, mixed payment methods, and detailed statement printing are enabled.

In ACT 10, the processor 1 checks whether the setting is for full printing. For example, the processor 1 refers to the setting table TA, and if it is confirmed that the “designated printing” is set, the result is NO, and the process proceeds to ACT 11.
In ACT 11, the processor 1 checks whether the transaction that was the subject of the payment process in ACT 4 or the recall process in ACT 5 is a business transaction. A business transaction is a transaction in which a customer purchases a product for business purposes. For example, if a predetermined condition is not met during the registration process in ACT 3 or the accounting process in ACT 4, such as the vendor card being read by the card reader/writer 10, the processor 1 determines NO and proceeds to ACT 12. A vendor card is a type of membership card, and is issued to a customer who conducts a business transaction.

In ACT 12, the processor 1 checks whether or not a statement has been specified. For example, the processor 1 displays a confirmation screen on at least one of the clerk's touch panel 4 and the customer's touch panel 13, and receives an instruction as to whether or not to print a statement. The clerk or customer instructs whether or not to print a statement by a predetermined operation, such as touching a button displayed on the confirmation screen. Then, in response to the instruction to print a statement, the processor 1 judges the answer to be YES and proceeds to ACT 13.
In ACT 10, if the processor 1 confirms that "print all" is set by referring to the setting table TA, for example, the processor 1 judges "YES" and proceeds to ACT 13. In ACT 11, if the processor 1 confirms that the transaction is a business transaction, the processor 1 judges "YES" and proceeds to ACT 13.

In ACT 13, the processor 1 calculates the pro rata tax amount. The pro rata tax amount is the tax amount obtained by prorating the tax amount for each taxation type to each payment method. Specifically, the processor 1 calculates the pro rata tax amount, for example, as follows. In the following example, we will use a transaction involving five items, totaling 61,395 yen, including one item with a displayed price of 11,111 yen when the "tax-exclusive method, tax rate 8%" is applied, one item with a displayed price of 15,321 yen when the "tax-exclusive method, tax rate 10%" is applied, one item with a displayed price of 12,222 yen when the "tax-inclusive method, tax rate 8%" is applied, one item with a displayed price of 15,321 yen when the "tax-inclusive method, tax rate 10%" is applied, and one item with a displayed price of 5,000 yen when the "tax-exempt" method is applied. The transaction will be paid for by "point payment" and "discount coupon payment" for 500 yen each, with the remaining amount being paid by "cash payment".

First, processor 1 calculates the total tax amount for each taxation type before calculating the pro rata tax amount. For example, in the above example, processor 1 calculates 888 yen for "tax-exclusive method, tax rate 8%" by [11,111 x 0.08], 1,532 yen for "tax-exclusive method, tax rate 10%" by [15,321 x 0.1], 905 yen for "tax-inclusive method, tax rate 8%" by [12,222 x 0.08 ÷ 1.08], and 1,392 yen for "tax-inclusive method, tax rate 10%" by [15,321 x 0.1 ÷ 1.10]. In this way, processor 1 executes information processing based on the information processing program, and the computer with processor 1 as its core functions as a first calculation means for calculating the total tax amount for products to which a taxation type is applied.

If the payment amount for the payment method subject to the tax type is SAA, the total tax amount for the tax type is TAA, and the total payment amount for the transaction is SAB, then the pro rata tax amount is calculated as [SAA x TAA / SAB]. However, in this embodiment, the calculation result using the above formula is rounded off. Any excess or shortfall in the tax amount resulting from this is adjusted by increasing or decreasing the calculation result for the payment method with the largest SAA.
The SAA and SAB are the same for all tax types: for "point payment", SAA = 500; for "discount coupon payment", SAA = 500; for "cash payment", SAA = 60,395 and SAB = 61,395.

In the case of "tax exclusive, tax rate 8%", TAA = 888. Thus, processor 1 calculates the pro rata tax amounts as 7 yen for "point payment", 7 yen for "discount coupon payment", and 874 yen for "cash payment". At this time, the above formula gives 7.2 yen, 7.2 yen, and 873.5 yen, which are rounded off to 7 yen, 7 yen, and 874 yen, and the total is 888 yen, so no adjustment is required.

In the case of "tax exclusive method, tax rate 10%", TAA = 1,532. Thus, processor 1 calculates the pro rata tax amount as 12 yen for "point payment", 12 yen for "discount coupon payment", and 1,508 yen for "cash payment". At this time, the above formula results in 12.4 yen, 12.4 yen, and 1,507.0 yen, which are rounded off to 12 yen, 12 yen, and 1,507 yen, for a total of 1,531 yen, leaving a shortfall of 1 yen. Therefore, processor 1 adds this 1 yen to the total, 1,508 yen, and determines the pro rata tax amount for "cash payment".

In the case of "tax-inclusive method, tax rate 8%," TAA = 905. Thus, processor 1 calculates the pro rata tax amounts as 7 yen for "point payment," 7 yen for "discount coupon payment," and 890 yen for "cash payment." Note that in this case, the above formula results in 7.3 yen, 7.3 yen, and 890.2 yen, which are rounded off to 7 yen, 7 yen, and 890 yen, for a total of 904 yen, leaving a shortfall of 1 yen. Therefore, processor 1 adds this 1 yen to the total, 891 yen, and determines the pro rata tax amount for "cash payment."

In the case of "tax-inclusive method, tax rate 10%", TAA = 1,392. Thus, processor 1 calculates the pro rata tax amount as 11 yen for "point payment", 11 yen for "discount coupon payment", and 1,370 yen for "cash payment". At this time, the above formula results in 11.3 yen, 11.3 yen, and 1,369.3 yen, which are rounded off to 11 yen, 11 yen, and 1,369 yen, for a total of 1,391 yen, leaving a shortfall of 1 yen. Therefore, processor 1 adds this 1 yen to the total, 1,370 yen, and determines the pro rata tax amount for "cash payment".

In this way, the processor 1 calculates the pro rata tax amount. Thus, by the processor 1 executing information processing based on the information processing program, the computer with the processor 1 as its central part functions as a second calculation means that individually calculates the amount of the total tax amount for each tax type to be applied to each of the multiple payment methods as the pro rata tax amount.

By the way, it would be useful to know how much of each payment these pro rata tax amounts are taxed on. Therefore, processor 1 will also calculate the pro rata payment amount here. The pro rata payment amount is the payment amount for each payment method pro rata for each tax type.

If the total displayed price of the products subject to the applicable tax type is denoted as ATA and the pro rata tax amount calculated as above is denoted as TAB, then the pro rata payment amount is calculated as [SAA x ATA ÷ SAB] for tax types that are tax-inclusive, and as [SAA x ATA ÷ SAB + TAB] for tax types that are tax-exclusive. However, in this embodiment, the calculation result using the above formula is rounded off. Any excess or shortfall in the payment amount that results from this is adjusted by increasing or decreasing the calculation result for the payment method with the largest SAA.

In the case of "tax exclusive, tax rate 8%", ATA = 11,111. Thus, processor 1 calculates the pro rata settlement amounts as 90 yen for "point payment", 90 yen for "discount coupon payment", and 10,931 yen for "cash payment". At this time, the above formula results in 90.4 yen, 90.4 yen, and 10,930.0 yen, which are rounded off to 90 yen, 90 yen, and 10,930 yen, for a total of 11,110 yen, leaving a shortfall of 1 yen. Processor 1 therefore adds this 1 yen to the total, 10,931 yen, and determines this to be the pro rata settlement amount for "cash payment".

In the case of "tax exclusive, tax rate 10%", ATA = 15,321. Thus, processor 1 calculates the pro rata settlement amounts as 125 yen for "point payment", 125 yen for "discount coupon payment", and 15,071 yen for "cash payment". At this time, the above formula results in 124.7 yen, 124.7 yen, and 15,071.4 yen, which are rounded off to 125 yen, 125 yen, and 15,071 yen, and the total is 15,321 yen, so no adjustment is necessary.

In the case of "tax-inclusive method, tax rate 8%," the ATA = 12,222. Thus, processor 1 calculates the pro rata settlement amount as 100 yen for "point payment," 100 yen for "discount coupon payment," and 12,023 yen for "cash payment." Note that in this case, the above formula results in 99.5 yen, 99.5 yen, and 12,022.9 yen, which are rounded off to 100 yen, 100 yen, and 12,023 yen, and the total is 12,223 yen, resulting in an excess of 1 yen. Processor 1 therefore subtracts this 1 yen to obtain 12,022 yen, which is the pro rata settlement amount for "cash payment."

In the case of "tax-inclusive method, tax rate 10%", ATA = 15,321. Thus, processor 1 calculates the pro rata settlement amounts as 125 yen for "point payment", 125 yen for "discount coupon payment", and 15,071 yen for "cash payment". At this time, the above formula results in 124.7 yen, 124.7 yen, and 15,071.4 yen, which are rounded off to 125 yen, 125 yen, and 15,071 yen, and the total is 15,321 yen, so no adjustment is necessary.

In the case of "tax exemption," ATA = 5,000. Thus, processor 1 calculates the pro rata settlement amount as 41 yen for "point payment," 41 yen for "discount coupon payment," and 4,918 yen for "cash payment." At this time, the above formula results in 40.7 yen, 40.7 yen, and 4,918.5 yen, which are rounded up or down to 41 yen, 41 yen, and 4,919 yen, for a total of 5,001 yen, resulting in an excess of 1 yen. Processor 1 therefore subtracts this 1 yen to obtain 4,918 yen, which is the pro rata settlement amount for "cash payment."

Note that, for both the pro rata tax amount and the pro rata settlement amount, the rounding method and the method of adjusting for excess or deficiency are merely examples, and may be determined as appropriate by, for example, the designer of the POS terminal device 100. For example, if the shortfall or excess is 2 yen or more, it is preferable to adjust multiple pro rata tax amounts or multiple pro rata settlement amounts.

In ACT 14, the processor 1 prints a detailed receipt. The detailed receipt is a receipt that shows the pro rata tax amount and the pro rata settlement amount in addition to the information shown on a general receipt such as that printed by other existing POS terminals.

FIG. 4 shows an example of a portion of a detailed receipt.
In FIG. 4, the area equivalent to the general receipt described above is omitted, and only the area following it is shown.

Processor 1 displays the product price and tax amount for each tax type in area ARA. In the first line of area ARA, Processor 1 displays the total of the displayed prices of the products subject to the transaction as the subtotal. Therefore, the subtotal does not include the tax amount for products to which tax-exclusive applies, but includes the tax amount for products to which tax-inclusive applies. In lines 2 to 12 of area ARA, Processor 1 displays the total of the displayed prices of the products for each tax type and the tax amount, as well as the total amount of tax-exclusive. In line 13 of area ARA, Processor 1 displays the total amount of all taxes. In line 14 of area ARA, Processor 1 displays the amount obtained by adding the tax-exclusive amount to the subtotal amount displayed in line 1 as the total amount. Therefore, this total is the total payment amount.

Following the area ARA, the processor 1 forms areas ARB, ARC, and ARD in this order.
In the area ARB, Processor 1 displays the pro rata settlement amount and the pro rata tax amount calculated as described above for "point payment". In the first line of the area ARB, Processor 1 displays the settlement amount to which "point payment" is applied. In the second and third lines of the area ARB, Processor 1 displays the pro rata settlement amount and the pro rata tax amount calculated for "tax-exclusive method, tax rate 8%". In the fourth and fifth lines of the area ARB, Processor 1 displays the pro rata settlement amount and the pro rata tax amount calculated for "tax-exclusive method, tax rate 10%". In the sixth and seventh lines of the area ARB, Processor 1 displays the pro rata settlement amount and the pro rata tax amount calculated for "tax-inclusive method, tax rate 8%". In the eighth and ninth lines of the area ARB, Processor 1 displays the pro rata settlement amount and the pro rata tax amount calculated for "tax-inclusive method, tax rate 10%". Processor 1 displays the calculated pro rata settlement amount for "non-taxable" in the 10th line of area ARB. Processor 1 displays the calculated pro rata tax amount for "non-taxable" in the 10th line of area ARB as 0 yen.
In area ARC, processor 1 displays the pro rata settlement amount and pro rata tax amount calculated as described above for "discount coupon payment" in the same layout as area ARB.
In area ARD, processor 1 displays the pro rata settlement amount and pro rata tax amount calculated as described above for "cash payment" in the same layout as area ARB.

Then, processor 1 generates image data representing an image of such a detailed receipt and instructs receipt printer 11 to print a receipt based on that image data. Following the instructions from processor 1, receipt printer 11 prints the image represented by the image data onto receipt paper. This prints a detailed receipt. In this way, processor 1 executes information processing based on the information processing program, and the computer with processor 1 as its central part functions as an output means that outputs the pro rata tax amount by having the receipt printer print a detailed receipt, which is a receipt showing the pro rata tax amount along with the details of the transaction.

In ACT 15, the processor 1 checks whether or not a receipt needs to be issued. For example, if the conditions for issuing a receipt are met, the processor 1 judges YES and proceeds to ACT 16. For example, during the registration process in ACT 3, the transaction process in ACT 4, and the callback process in ACT 5 in FIG. 2, the processor 1 judges YES if a receipt is instructed to be issued by a predetermined operation on either the clerk's touch panel 4 or the customer's touch panel 13. Alternatively, for example, in ACT 15, the processor 1 waits for a designation of whether or not a receipt needs to be issued by a predetermined operation on either the clerk's touch panel 4 or the customer's touch panel 13, and judges YES if a designation that a receipt needs to be issued is made. Alternatively, the processor 1 may unconditionally judge YES, for example, regardless of the instruction of the clerk or the customer. The circumstances under which ACT 15 is judged to be YES may be determined as appropriate by, for example, the designer of the POS terminal device 100.

In ACT 16, the processor 1 prints a detailed receipt. The detailed receipt is a receipt that shows the pro rata tax amount and the pro rata settlement amount in addition to the information shown on a general receipt such as that printed by other existing POS terminals.

FIG. 5 is a diagram showing an example of a portion of a detailed receipt.
In FIG. 5, a portion of the area equivalent to the general receipt described above is shown, and an area showing the pro rata tax amount and the pro rata settlement amount is shown.

The processor 1 forms the area ARE in which an image shown on a typical receipt is formed, followed by areas ARF, ARG, and ARH in that order. The areas ARF, ARG, and ARH show the same information as the areas ARB, ARC, and ARD in FIG.
The processor 1 then generates image data representing an image of such a detailed receipt, and instructs the receipt printer 11 to print a receipt based on that image data. The receipt printer 11 prints the image represented by the image data on receipt paper in accordance with the instructions from the processor 1. This prints a detailed receipt.

When the printing of the detailed receipt is completed, the processor 1 returns to the standby state of ACT1 and ACT2 in FIG. 2. Note that if the conditions for issuing a receipt are not met, for example, the processor 1 judges NO in ACT15 in FIG. 3 and returns to the standby state of ACT1 and ACT2 in FIG. 2 without executing ACT16.

If there is no mixture of tax types for the products that are the subject of the transaction registered in ACT 3 in FIG. 2 or the products that are the subject of the transaction that is the subject of the recall process in ACT 5, processor 1 judges NO in ACT 7 in FIG. 3. If multiple payment methods are not mixed in the payment process in ACT 4 in FIG. 2 or the payment of the transaction that is the subject of the recall process in ACT 5, processor 1 judges NO in ACT 8 in FIG. 4. If "invalid" is recorded as the setting for detail printing in setting table TA, processor 1 judges NO in ACT 9. Processor 1 also judges NO if it is specified in ACT 12 that detail printing should not be performed. In either of these cases, processor 1 proceeds to ACT 17.

In ACT 17, the processor 1 prints a regular receipt. A regular receipt is a receipt that shows the information shown on a general receipt printed by other existing POS terminals, and does not show the pro rata tax amount or pro rata payment amount.

In ACT 18, the processor 1 checks whether or not it is necessary to issue a receipt. For example, if the conditions for issuing a receipt are met, the processor 1 determines YES and proceeds to ACT 19. The above conditions may be the same as those in ACT 15, or may be different.

In ACT 19, the processor 1 prints a regular receipt. A regular receipt is a receipt that shows the information shown on a general receipt printed by other existing POS terminals, and does not show the pro rata tax amount or the pro rata payment amount.

When the printing of the normal receipt is completed, the processor 1 returns to the standby state of ACT1 and ACT2 in FIG. 2. Note that if the conditions for issuing a receipt are not met, for example, the processor 1 judges NO in ACT18 in FIG. 3 and returns to the standby state of ACT1 and ACT2 in FIG. 2 without executing ACT19.

As described above, the POS terminal device 100 prints a detailed receipt showing the pro rata tax amount for each tax type and each payment method. Therefore, the pro rata tax amount can be easily confirmed from the detailed receipt, and tax processing can be simplified for transactions that involve a mixture of multiple products to which different tax types are applied and in which the payment amount is shared across multiple payment methods.

The POS terminal device 100 also prints a detailed receipt showing the pro rata tax amount for each tax type and each payment method. This allows the pro rata tax amount to be easily confirmed from the detailed receipt, simplifying tax processing for transactions involving a mixture of multiple products to which different tax types are applied and in which the payment amount is shared across multiple payment methods.

The POS terminal device 100 also displays the pro rata payment amount for each tax type and each payment method on the detailed receipt and detailed invoice. This allows the pro rata tax amount to be easily confirmed from the detailed invoice, further simplifying tax processing for transactions involving a mixture of multiple products to which different tax types are applied and in which the payment amount is shared across multiple payment methods.

However, as shown in Figures 4 and 5, the detailed receipt and detailed receipt are significantly longer than the normal receipt and normal receipt. The pro rata tax amount and pro rata payment amount are often unnecessary for many general consumers, and if detailed receipts and detailed receipts are given to such customers, they may feel bothered. In addition, printing detailed receipts and detailed receipts for customers who do not need the pro rata tax amount and pro rata payment amount will waste receipt paper. However, the POS terminal device 100 prints detailed receipts and detailed receipts as necessary according to user settings and user instructions. This makes it possible to prevent customers from being bothered or receipt paper from being wasted. In particular, the POS terminal device 100 prints detailed receipts and detailed receipts when it is determined that the transaction is a business transaction, for example because the vendor card has been read. This makes it easy to print the necessary detailed receipts and detailed receipts.

This embodiment can be modified in various ways as follows.
It may be realized as a self-service or semi-self-service POS terminal device, or as an information processing device that calculates and outputs the pro rata tax amount for a transaction registered and settled at another POS terminal device, or for a transaction registered at another registration device and settled at another settlement device.

It may be possible to print only either the detailed receipt or the detailed invoice. That is, the processor 1 may proceed from ACT 14 to ACT 18 in FIG. 3, for example. Alternatively, the processor 1 may execute a process similar to ACT 17 instead of ACT 14 in FIG. 3, and then proceed to ACT 15.

When it is necessary to print a receipt, the processor 1 may determine whether to print a detailed receipt or a regular receipt separately from determining whether to print a detailed receipt or a regular receipt.

The output of the prorated tax amount is not limited to printing, but can be output using various other output methods, such as sending it to another information terminal or writing it to a storage medium.

The functions realized by processor 1 through information processing can be realized in part or in whole by hardware that executes information processing not based on a program, such as a logic circuit. Each of the above functions can also be realized by combining software control with hardware such as the above logic circuits.
