(Embodiment)
An information processing device, an information processing method, and a program according to an embodiment of the present invention will be described in detail with reference to the drawings. The same or corresponding parts in the drawings are designated by the same reference numerals. The following description will be given using an example in which the information processing device of the present invention is applied to an information processing system 1 shown in FIG.

In information processing system 1, as shown in FIG. 1, information terminal 100 and information processing device 300 are connected to each other so that they can communicate with each other via network 210. In the illustrated example, there is a single information terminal 100, but there may be multiple information terminals 100. Furthermore, by incorporating the functions of information processing device 300 into information terminal 100, it is possible for information terminal 100 to function as information processing device 300 as well. However, for ease of understanding, this embodiment will be described distinguishing between information terminal 100 and information processing device 300.

As shown in FIG. 1, the information terminal 100 is an information terminal connected to a network 210 such as the Internet. The information terminal 100 is an information terminal (a so-called computer) such as a credit card company's mobile phone, smartphone, tablet, or PC (Personal Computer), and is capable of sending and receiving various data to and from the information processing device 300 via the network 210. Note that the information terminal 100 is not limited to a credit card company terminal and may be, for example, a store information terminal. The information terminal 100 generates transaction information such as sales and returns and transmits it to the information processing device 300.

The information processing device 300 is an information terminal such as a mobile phone, smartphone, tablet, or PC, and is capable of sending and receiving various data to and from the information terminal 100 via the network 210. The information processing device 300 provides a service that performs payment processing, such as sales and returns, based on transaction information received from the information terminal 100.

Next, the configuration of the information terminal 100 will be described with reference to Figure 2. As mentioned above, since there are multiple information terminals 100, the other information terminals 100 also have at least the same configuration.

As shown in FIG. 2, the information terminal 100 includes a memory unit 110, a control unit 120, an input/output unit 130, a communication unit 140, and a system bus (not shown) that interconnects these units.

The storage unit 110 includes a ROM (Read Only Memory) and a RAM (Random Access Memory). The ROM stores the program 111 executed by the CPU (Central Processing Unit) of the control unit 120, as well as various data (not shown) required in advance to execute the program 111.

Program 111 is a program that executes the transaction information transmission process described below, and is pre-stored in storage unit 110. Specifically, program 111 is a program for generating a transaction screen, which is an input screen for generating transaction information necessary for performing payment processing, and a program for generating transaction information described below based on information entered on the transaction screen.

The control unit 120 is composed of a CPU, an ASIC (Application Specific Integrated Circuit), etc. The control unit 120 operates in accordance with the program 111 stored in the memory unit 110 and executes processing in accordance with the program. The control unit 120 has the following main functional units provided by the program 111 stored in the memory unit 110: a transaction screen generation unit 121, a transaction information generation unit 122, and a transaction information transmission unit 123.

The transaction screen generation unit 121 is a functional unit that generates an input screen for inputting each item included in the transaction information based on user operations on the input/output unit 130. Specifically, the transaction screen generation unit 121 generates an input screen that allows input of information for each item included in the transaction information shown in FIG. 3, such as transaction type and transaction amount (Japanese yen). Note that the transaction screen may be generated so that items included in the transaction information, such as transaction type and original transaction allocation category, are selectable. Note that the transaction screen generation unit 121 may generate a transaction screen by, for example, reading a transaction screen that has been stored in advance in the memory unit 110.

The transaction information generation unit 122 is a functional unit that generates the transaction information shown in Figure 3 based on the information entered into the transaction screen generated by the transaction screen generation unit 121. Specifically, the transaction information generation unit 122 determines whether or not there are any input errors in the information entered into the transaction screen, and if there are no input errors, extracts the entered information and generates the transaction information shown in Figure 3. Input errors are determined to have occurred, for example, when letters are entered in an input field where numbers should be entered, or when there are too few or too many digits in an input field that should be six digits. The criteria for determining whether or not there is an input error may be set in advance by the user.

Figure 3 is an explanatory diagram showing an example of transaction information. As shown, the transaction information includes the transaction type, transaction amount (Japanese yen), merchant number, terminal processing serial number, member number, rate designation date, and original transaction allocation category. There are two transaction types: "sales" and "returns," which indicate the type of transaction. The transaction amount (Japanese yen) indicates the amount to be paid. The merchant number indicates a number used to identify the purchase store. The terminal processing serial number indicates the processing serial number assigned to each information terminal 100 at the card company. Even if there are multiple information terminals 100, each information terminal 100 is assigned a unique number. The member number indicates the credit number to be used for payment. The rate designation date indicates the date of the rate to be used for payment. Specifically, as shown, if the rate designation date is "2021/2/1," it specifies that payment will be made at the rate of February 1, 2021. The original transaction allocation category is set to "0," "1," or blank to indicate whether past transaction information will be allocated. The allocation of past transaction information will be described later. Note that the rate designation date and original transaction allocation category may not be entered. Furthermore, the transaction amount (Japanese yen) is set to "Japanese yen" in this embodiment because it is assumed that the purchase will be made in Japan and then returned. However, if the information processing system 1 is applied to a transaction overseas, the currency used will be that of the overseas country. Furthermore, although the illustrated example omits information regarding the currency of the country in which the payment will be made, the transaction information also includes information regarding the currency used, indicating the currency of the country in which the payment will be made. For example, if a person residing in the United States, as the first country, purchases goods worth 5,000 yen in Japan, as the second country, and then returns goods worth 2,500 yen, the transaction information shown in Figure 3 is generated.

Returning to Figure 2, the transaction information transmission unit 124 is a functional unit that transmits the transaction information generated by the transaction information generation unit 122 to the information processing device 300 via the communication unit 140.

The input/output unit 130 is composed of a keyboard, mouse, camera, microphone, LCD display, organic EL (Electro-Luminescence) display, etc., and is a device for inputting and outputting various types of data.

The communication unit 140 is a device that enables the information terminal 100 to communicate with the information processing device 300 via the network 210.

These functional units work together to enable the information terminal 100 to perform the function of generating transaction information and transmitting it to the information processing device 300.

The above is the configuration of the information terminal 100. Next, the configuration of the information processing device 300 will be explained with reference to Figure 4. As shown in Figure 4, the information processing device 300 includes a memory unit 310, a control unit 320, an input/output unit 330, a communication unit 340, and a system bus (not shown) that interconnects these units.

The memory unit 310 includes a ROM (Read Only Memory), a RAM (Random Access Memory), etc. The ROM stores a program 311 executed by the CPU (Central Processing Unit) of the control unit 320, past transaction information 312, rate information 313, and various data (not shown) required in advance to execute the program 311.

Program 311 is a program for executing the settlement processing described below. Specifically, program 311 is a program for realizing the functions of the original transaction allocation classification determination unit 321, transaction information allocation unit 322, rate acquisition unit 323, and sales return processing unit 324 described below, and is stored in advance in memory unit 310.

Past transaction information 312 is a database that stores transaction information received from information terminal 100 during past payment processes. Specifically, past transaction information 312 includes the transaction type, transaction amount (Japanese yen), affiliated store number, terminal processing serial number, member number, rate designation date, original transaction allocation category, and the date and time of payment. Each time a payment process is performed, past transaction information 312 is updated and new transaction information is stored.

Rate information 313 is accumulated information on exchange rates that change daily, and is a database of daily exchange rates that associates dates with exchange rates. Rate information 313 associates the rates of multiple countries with dates. Each time the date is updated and the exchange rate for that day is determined, rate information 313 is transmitted from another information terminal via network 210 and stored in memory unit 310.

The control unit 320 is composed of a CPU, an ASIC (Application Specific Integrated Circuit), etc. The control unit 320 operates in accordance with the program 311 stored in the memory unit 310 and executes processing in accordance with the program. The control unit 320 has the following main functional units provided by the program 311 stored in the memory unit 310: a primary transaction allocation classification determination unit 321, a transaction information allocation unit 322, a rate acquisition unit 323, and a sales return processing unit 324.

The original transaction allocation category determination unit 321 is a functional unit that determines the value of the original transaction allocation category included in the transaction information received from the information terminal 100 during the settlement process described below. Specifically, the original transaction allocation category determination unit 321 determines whether the value of the original transaction allocation category included in the transaction information received from the information terminal 100 is "0", "1", or "other (including blank)". Note that if the value of the original transaction allocation category included in the transaction information received from the information terminal 100 is neither "0" nor "1", i.e., "other (including blank)", the original transaction allocation category determination unit 321 also determines whether the transaction type included in the transaction information received from the information terminal 100 is "returned goods".

The transaction information allocation unit 322 is a functional unit that allocates transactions from past transaction information 312 that correspond to transactions indicated by transaction information received from information terminal 100. For example, for a return transaction of 5,000 yen with membership number ZZZZZZZZZZZZZZZZZZ at member store number YYYYYY and rate specified date N/N/N, the transaction information allocation unit 322 allocates the corresponding sales transaction from past transaction information 312 based on the member store number, membership number, transaction amount (Japanese yen), and rate specified date. In other words, allocation refers to extracting past transaction information that matches each item of the received transaction information. If past transaction information that matches each item of the received transaction information does not exist and extraction is not possible, allocation fails; if past transaction information that matches each item of the received transaction information can be extracted, allocation is successful.

The rate acquisition unit 323 is a functional unit that acquires the exchange rate for the rate-specified date indicated in the transaction information received from the information terminal 100 from the rate information 313. The rate acquisition unit 323 may also acquire the exchange rate for the rate-specified date from an external source via the network 210.

The sales/returns processing unit 324 is a functional unit that performs settlement for transactions of the type indicated by the transaction category included in the transaction information received from the information terminal 100. Specifically, if the transaction category included in the transaction information is "sales," the sales/returns processing unit 324 performs settlement processing corresponding to sales; if the transaction category is "returns," the sales/returns processing unit 324 performs settlement processing corresponding to returns.

The input/output unit 330 is composed of a keyboard, mouse, camera, microphone, LCD display, organic EL (Electro-Luminescence) display, etc., and is a device for inputting and outputting various types of data.

The communication unit 340 is a device that enables the information processing device 300 to communicate with other information terminals via the network 210.

By having these functional units work together, the information processing device 300 is able to flexibly specify exchange rates even in special cases during payment processing.

The above is the configuration of the information processing device 300. Next, the operation of the information processing system 1 will be described. First, the operation of the information terminal 100 will be described. Figure 5 is a flowchart showing an example of a transaction information transmission process executed by the information terminal 100. The transaction information transmission process is initiated when a user operates the input/output unit 130.

When the transaction information transmission process shown in FIG. 5 is started, the control unit 120 first uses the function of the transaction screen generation unit 121 to generate a transaction screen, which is an input screen that allows the user to enter information for each item, such as the transaction type and transaction amount (Japanese yen) (step S101). Note that in step S101, as described above, the transaction screen may be generated by reading a transaction screen that has been stored in advance in the memory unit 110.

After executing the processing of step S101, the control unit 120, using the function of the transaction information generation unit 122, determines whether or not there is an input error in the information entered on the transaction screen (step S102). Specifically, in the processing of step S102, an input error is determined to have occurred if something other than a number is entered in an input field where a number is expected, if an item requiring input is left blank, or if the number of digits in an input field is insufficient or excessive. As described above, the criteria for determining whether or not an input error has occurred are set in advance by the user for each item. Note that in the processing of step S102, an input error may be determined to have occurred if a predetermined period of time has passed, for example, if no input is made for more than 15 minutes.

If it is determined in step S102 that an input error has occurred (step S102; No), the control unit 120 simply terminates the transaction information transmission process. On the other hand, if it is determined in step S102 that no input error has occurred (step S102; Yes), the control unit 120 uses the function of the transaction information generation unit 122 to generate transaction information based on the information entered on the transaction screen (step S103). Specifically, in the processing of step S103, the control unit 120 extracts information corresponding to the transaction type, transaction amount (Japanese yen), affiliated store number, terminal processing serial number, member number, rate designation date, and original transaction allocation category entered on the transaction screen, and generates transaction information as shown in Figure 3.

After executing the processing of step S103, the control unit 120, using the function of the transaction information transmission unit 124, transmits the transaction information generated in the processing of step S103 to the information processing device 300 (step S104), and terminates the transaction information transmission processing. As a result, the generated transaction information is transmitted to the information processing device 300.

Next, the operation of the information processing device 300 will be described. Figure 6 is a flowchart showing an example of payment processing executed by the information processing device 300. Execution of the payment processing is initiated by receiving transaction information from the information terminal 100. Note that the payment processing may also be initiated by a user operating the input/output unit 330. In this case, for example, the user may select which of multiple pieces of transaction information received from the information terminal 100 the payment processing should be based on. The step in which the information processing device 300 receives transaction information from the information terminal 100 via the network 210 corresponds to a payment information receiving step, and the communication unit 340 having the function of executing this corresponds to a payment information receiving means.

When the settlement process begins, the control unit 320 first determines whether the original transaction allocation category is "1" using the function of the original transaction allocation category determination unit 321 (step S201). Specifically, in the processing of step S201, the control unit 320 checks the original transaction allocation category item included in the transaction information received from the information terminal 100 and determines whether its value is "1".

If it is determined in the processing of step S201 that the original transaction allocation category is not "1" (step S201; No), the control unit 320 uses the function of the original transaction allocation category determination unit 321 to determine whether the original transaction allocation category is "0" (step S202). In the processing of step S202, similar to the processing of step S201, the original transaction allocation category item included in the transaction information received from the information terminal 100 is checked and it is determined whether the value is "0".

If it is determined in the processing of step S202 that the original transaction allocation category is not "0" (step S202; No), the control unit 320 uses the function of the original transaction allocation category determination unit 321 to determine whether the transaction type is "returned goods" (step S203). Specifically, in the processing of step S203, the control unit 320 checks the transaction type item included in the transaction information received from the information terminal 100 and determines whether the information for that item is "returned goods."

If the processing in step S201 determines that the original transaction allocation category is "0" (step S202; Yes), or if the processing in step S203 determines that the transaction type is "returned goods" (step S203; Yes), the control unit 320 uses the function of the transaction information allocation unit 322 to allocate past transaction information (step S204). Specifically, in the processing in step S204, the transaction corresponding to the transaction indicated by the transaction information received from the information terminal 100 is allocated from the past transaction information 312.

After executing the processing of step S204 in FIG. 6, the control unit 320 determines whether allocation was successful or not using the function of the transaction information allocation unit 322 (step S205). Specifically, the processing of step S205 determines whether a transaction corresponding to the transaction indicated by the transaction information received from the information terminal 100 in the processing of step S204 was allocated from the past transaction information 312, i.e., whether past transaction information corresponding to the received transaction information was able to be extracted from the past transaction information 312.

If it is determined that allocation was successful in the processing of step S205 (step S205; Yes), that is, if past transaction information corresponding to the received transaction information can be extracted from past transaction information 312, the control unit 320 uses the function of the rate acquisition unit 323 to acquire the exchange rate for the date indicated by the settlement rate date in the extracted past transaction information from rate information 313 (step S206). Note that if allocation was successful in the processing of step S205, the settlement rate date in the allocated past transaction information and the rate designation date included in the received transaction information will be the same, and therefore the exchange rate for the date indicated by the rate designation date included in the transaction information received from information terminal 100 may be acquired in the processing of step S206.

On the other hand, if it is determined in the processing of step S203 that the transaction type is not "return" (step S203; No), or if it is determined in the processing of step S205 that allocation has failed (step S205; No), that is, if past transaction information corresponding to the transaction information received in step S205 cannot be extracted from past transaction information 312, the control unit 320 uses the function of the rate acquisition unit 323 to acquire the exchange rate on the day the payment processing was executed, i.e., today's rate (the rate on the day of processing) (step S207). Note that each time the date is updated and the exchange rate for that day is determined, it is registered in rate information 313 from another information terminal via network 210. Therefore, the today's rate in step S207 can be acquired from rate information 313, but it may also be acquired from another information terminal via network 210.

Furthermore, if the processing of step S201 determines that the original transaction allocation category is "1" (step S201; Yes), the control unit 320 uses the function of the rate acquisition unit 323 to acquire the exchange rate for the date indicated by the rate designation date included in the received transaction information from the rate information 313 (step S208).

After executing the processing of step S207 or step S208, the control unit 320, using the function of the sales return processing unit 324, settles the transaction type indicated by the transaction category included in the transaction information received from the information terminal 100 (step S209), and terminates the settlement processing. Specifically, in step S209, if the transaction category included in the transaction information received from the information terminal 100 is "sales," the control unit 320 processes the sales amount indicated by the transaction amount (Japanese yen) using the specified exchange rate route. On the other hand, if the transaction category is "returns," the control unit 320 processes the refund of the amount indicated by the transaction amount (Japanese yen) using the specified exchange rate route. Furthermore, in the processing of step S209, the transaction information received from the information terminal 100 is registered in the past transaction information 312. At that time, the item name of the rate designation date included in the transaction information received from the information terminal 100 is changed to the item "settlement rate date." The settlement rate date indicates the date of the exchange rate used in the settlement processing. Note that step S209 corresponds to the settlement step, and the function of the sales return processing unit 324 that executes the processing of step S209 corresponds to the payment method.

Specifically, an example will be described in which transaction information shown in Figure 3 is received from information terminal 100. As mentioned above, the transaction information shown in Figure 3 is transaction information generated when a person residing in the United States (a first country) purchases goods worth 5,000 yen in Japan (a second country) and then returns goods worth 2,500 yen. In other words, the transaction information shown in Figure 3 is transaction information for a partial return corresponding to the previous 5,000 yen sales.

Upon receiving the transaction information shown in FIG. 3, the information processing device 300 executes the settlement process shown in FIG. 6. Because the original transaction allocation category in the received transaction information is "1," step S201 returns "Yes," and step S208 obtains the exchange rate for February 1, 2021, the rate designation date for the transaction information shown in FIG. 3. Then, step S209 in FIG. 6 executes the settlement process corresponding to the return transaction type shown in FIG. 3, resulting in a return of 2,500 yen at the exchange rate for February 1, 2021. Conventionally, when making a return settlement, the exchange rate at the time of the sales settlement was used only if the transaction amount (Japanese yen), affiliated store number, and membership number included in the received transaction information matched the previous transaction information corresponding to the return settlement. However, in special cases such as partial returns, the transaction amount (Japanese yen) in the received transaction information did not match the previous transaction information, and the exchange rate at the time of the sales settlement was not specified. According to the information processing device 300 of this embodiment, the value of the original transaction allocation category allows settlement to be made using the exchange rate on the rate specification date without having to allocate past transaction information. Therefore, exchange rates can be flexibly specified even in special cases such as partial returns.

Next, an example will be described in which the transaction information shown in Figures 7(A), (B), and (C) is received in this order. Specifically, the transaction information shown in Figure 7(A) is an example of a case in which a sales payment of 250 yen was made in the past and transaction information for a return payment was generated corresponding to that, but transaction information for a return payment of 2,500 yen was mistakenly generated, i.e., an example of transaction information indicating an erroneous return transaction. The transaction information shown in Figure 7(B) is an example of transaction information for offsetting the erroneous return transaction indicated by the transaction information shown in Figure 7(A) (transaction information for a sales payment corresponding to the erroneous return shown in Figure 7(A)). The transaction information shown in Figure 7(C) is an example of transaction information for a return transaction corresponding to a sales payment of 250 yen made in the past.

First, upon receiving the transaction information shown in FIG. 7(A), the information processing device 300 executes the settlement process shown in FIG. 6. Because the original transaction allocation category in the received transaction information is "0," a "No" determination is made in step S201 and a "Yes" determination is made in step S202. Then, in the process of step S204, an attempt is made to allocate from past transaction information 312 the transaction corresponding to the transaction in the received transaction information shown in FIG. 7(A). As described above, the transaction information shown in FIG. 7(A) is transaction information for a return settlement of 2,500 yen that was mistakenly generated after a previous sales settlement of 250 yen. Therefore, in the process of step S204 of FIG. 6, the following transaction information is attempted to be allocated from past transaction information 312: affiliated store number "222222," member number "4222XXXXXX111111," transaction amount "2,500," settlement rate date "the day on which a sale of 250 yen was made," and transaction type "sales," which are the same as the respective items in the transaction information shown in FIG. 7(A). However, as mentioned above, the transaction information shown in FIG. 7(A) is transaction information indicating a mistaken return transaction, and therefore the corresponding transaction, i.e., the past sales payment of 2,500 yen, does not exist in past transaction information 312. Therefore, in the processing of step S204 in FIG. 6, the corresponding transaction is not allocated, and the processing of step S205 returns No.

Next, step S207 in Figure 6 is executed, and today's rate is obtained as the exchange rate. In this example, the date on which the payment process was performed is February 1, 2021. As a result, in step S209, a return transaction of 2,500 yen will be performed at today's exchange rate (the exchange rate on February 1, 2021).

Next, when the transaction information shown in FIG. 7(B) is received, the information processing device 300 executes the settlement process shown in FIG. 6 again. Because the original transaction allocation category in the received transaction information is "1," a Yes determination is made in step S201, and in the processing of step S208, the exchange rate for February 1, 2021, which is the rate specification date in the transaction information shown in FIG. 7(B), i.e., the exchange rate on the date the transaction (settlement) of the transaction information shown in FIG. 7(A) was made, is obtained. Then, in the processing of step S209 in FIG. 6, a sales process of 2,500 yen is performed. As a result, the offset of the transaction shown in the transaction information in FIG. 7(A) is performed at the same exchange rate.

As described above, when making a return payment, the exchange rate at the time of the sales payment was used only if the items included in the received transaction information, such as the transaction amount (Japanese yen), affiliated store number, and membership number, matched the past transaction information corresponding to the return payment. Furthermore, unlike returns, there is typically no corresponding past transaction for sales payments, so the exchange rate on the day of the sales payment was used without referencing past transaction information. Therefore, when making an erroneous return transaction and offsetting the erroneous return, the exchange rate on the day of each transaction was previously used, and the exchange rate at the time of offsetting could not be flexibly specified. The information processing device 300 according to this embodiment makes it possible to offset using the exchange rate on the day the erroneous return transaction was made, allowing for flexible exchange rates to be specified even in special cases.

Next, when the transaction information shown in FIG. 7(C) is received, the information processing device 300 executes the settlement process shown in FIG. 6 again. Because the original transaction allocation category in the received transaction information is "0," a No determination is made in step S201 and a Yes determination is made in step S202. Then, in the processing of step S204, an attempt is made to allocate from past transaction information 312 the transaction corresponding to the transaction in the received transaction information shown in FIG. 7(C). As described above, the transaction information shown in FIG. 7(C) is transaction information for a return transaction corresponding to a past sales settlement of 250 yen. Therefore, in the processing of step S204 of FIG. 6, the transaction information of the affiliated store number "222222," member number "4222XXXXXX111111," transaction amount "250," settlement rate date "the day when a sale of 250 yen was made," and transaction type "sales," which are the same as the respective items in the transaction information shown in FIG. 7(C), is allocated from past transaction information 312. That is, in the processing of step S204 in FIG. 6, transaction information corresponding to a past sales settlement of 250 yen is retrieved from past transaction information 312. Therefore, in the processing of step S204 in FIG. 6, the corresponding transaction is retrieved, and the processing of step S205 returns Yes.

Next, step S206 in Figure 6 is executed, and the transaction rate allocated in step S205, i.e., the rate on the day when 250 yen was sold, is obtained as the exchange rate. As a result, in step S209, the return processing for 250 yen is performed at the exchange rate on the day when 250 yen was sold. This completes the official return processing.

In this way, the information processing device 300 according to this embodiment includes information on the original transaction allocation category and the rate designation date in the transaction information, and performs processing according to the original transaction allocation category, thereby enabling exchange rates to be flexibly specified even in special cases where exchange rates could not previously be flexibly specified.

(Modification)
It should be noted that the present invention is not limited to the above-described embodiment, and various modifications and applications are possible. For example, the information processing device 300 according to the above-described embodiment does not need to have all of the technical features described above, but may have some of the configurations described in the above-described embodiment so as to solve at least one problem in the prior art. Furthermore, at least a portion of each of the following modifications may be combined.

In the above embodiment, in the processing of step S102 shown in Figure 5, an input error is determined to have occurred if, for example, something other than a number is entered in an input field where a number is expected, if an item requiring input is left blank, or if the number of digits in an input field is insufficient or too many, but this is just one example. For example, it is also possible to set restrictions on the date that can be specified for the rate specification date, such as a limit on the number of days from the current date that can be specified, and to issue an error if the rate specification date is not within the specified date.

Separately, the information processing device 300 may determine whether the rate designation date is one that can be designated. For example, when transaction information is received from the information terminal 100, the settlement process shown in FIG. 6 is executed, but before processing step S201, it may determine whether the rate designation date included in the transaction information is within the designated date. The process of determining whether the rate designation date is within the designated date corresponds to the determination means. If the rate designation date included in the transaction information is within the designated date, the process proceeds to step S201. On the other hand, if the rate designation date included in the transaction information is not within the designated date, a message indicating an error and that the rate designation date should be within the designated date or should not be designated and the transaction should be resent can be sent to the information terminal 100. The process of sending the message indicating the error and that the rate designation date should be within the designated date or should not be designated and the transaction should be resent can be sent to the information terminal 100.

Furthermore, if restrictions are placed on the dates that can be designated as rate designation dates, the exchange rate information for dates beyond the designated date may be periodically deleted from the daily exchange rates stored as rate information 313 so that the exchange rate information remains within the designated date.

In addition, in the above embodiment, an example was shown in which the date of the exchange rate to be used was specified by inputting the rate designation date in the transaction information, but this is just one example, and other information other than a date can be used as long as it can identify the exchange rate to be used. Furthermore, the exchange rate itself may be input instead of the rate designation date. Then, on the information processing device 300 side, in the processing of step S208 in FIG. 6 or step S206 (if the answer in step S202 is Yes), it is sufficient to decide to use the exchange rate indicated in the transaction information rather than obtaining the exchange rate for the rate designation date. This makes it possible to handle cases where rate information 313 is not available or where settlement at a specific exchange rate is desired. The date indicated as the rate designation date or information that can identify the exchange rate to be used corresponds to rate identification information.

Note that the information processing device 100 according to the above embodiment can be realized using a normal computer, rather than a dedicated device. For example, the information processing device 100 that executes the above-described processes may be configured by installing a program for executing any of the above-described processes on a computer from a recording medium that stores the program on the computer. Also, a single information processing device 100 may be configured by multiple computers operating in cooperation with each other.

Furthermore, if the above-mentioned functions are realized by sharing the responsibilities between an OS (Operating System) and an application, or by collaboration between the OS and an application, only the parts other than the OS may be stored on the medium.

It is also possible to superimpose a program onto a carrier wave and distribute it over a communications network. For example, the program may be posted on a bulletin board (BBS, Bulletin Board System) on the communications network and distributed over the network. These programs may then be launched and run under the control of the operating system in the same way as other application programs, thereby enabling the above-mentioned processing to be performed.
