The reference value of the above is read from the storage unit 310, the reference value of the exchange rate read out, and the exchange rate between the specified type of ordinary currency and the local currency are determined based on various conditions, and the determined exchange rate is determined. Is output to the calculation unit 334.

If the amount acquired by the amount acquisition unit 333 is the amount of the ordinary currency before the exchange, the calculation unit 334 calculates the amount to be deducted from the balance of the ordinary currency based on the amount of the ordinary currency before the exchange. If the amount acquired by the amount acquisition unit 333 is the amount of the exchanged local currency, the calculation unit 334 will use the ordinary currency based on the amount of the exchange rate between the regional currency and the ordinary currency output from the rate determination unit 332. Calculate the deduction amount to the balance of. The calculation of the amount to be added to the balance of the local currency is the same as the process of step B12 described above.

Next, the instruction unit 335 issues a payment instruction for designating the ordinary currency management information and the amount of subtraction to the balance of the ordinary currency calculated by the calculation unit 334 (step B23). The payment instruction is an instruction to subtract the balance of the ordinary currency associated with the designated ordinary currency management information.

The update unit of the electronic money management device 51 receives the payment instruction and performs payment processing when the deduction amount to the balance of the ordinary currency corresponding to the ordinary currency management information is equal to or less than the balance corresponding to the ordinary currency management information ( Step D22). Here, the update unit updates the balance of the account corresponding to the managed currency management information based on the subtraction amount specified by the payment instruction. If the amount deducted from the balance of the ordinary currency corresponding to the ordinary currency management information exceeds the balance corresponding to the ordinary currency management information, the update unit does not perform payment processing and notifies the management device 30 of an error. conduct.

After the payment processing is completed, the local currency management device 40 transmits a completion notification notifying the completion of the payment processing to the management device 30.

Upon receiving the payment completion notification in the management device 30, the instruction unit 335 gives a charge instruction to the local currency management device 40 to specify the local currency management information and the additional amount of the local currency (step B24).

After the charge instruction is given by the control unit 330, steps C21, B25 and A26 are performed. Steps C25, B25 and A26 correspond to steps C11, B14 and A14, respectively.

<Charging process of local currency using credit card>
FIG. 7 is a sequence diagram showing a local currency charge process using a credit card executed by the currency charge system 1.

First, the currency charging device 11 acquires the local currency management information from the code attached to the admission ticket of the user's World Expo (step A31).

Next, when the user inserts the credit card into the card reader 104, the card reader 104 acquires the ordinary currency management information from the credit card (step A32).

Subsequently, when the input of the authentication information (for example, the password) is received through the display operation unit 101 (step A33), the control unit 140 makes an authentication request for designating the received authentication information and the ordinary currency management information (step A33). Step A34).

When the management device 30 receives the authentication request from the currency charging device 11, the management device 30 encrypts the authentication information specified by the authentication request and the ordinary currency management information (step B31), and transfers the encrypted information to the credit management device 52. Send.

Subsequently, the credit management device 52 decrypts the encrypted information and performs an authentication process based on the decrypted information (step E31). When it is determined that the credit card can be used as a result of the authentication process, the authentication completion notification is transmitted to the currency charging device 11 via the management device 30.

The processing after the charge request (step A35) by the currency charging device 11 is derived from the difference in the characteristics of the use of electronic money and the use of credit cards, that is, whether to manage the balance or the available amount. Except for this, it is the same as steps A25, A26, B21 to B25, D22, and C21 in the charging process of the local currency using electronic money.

The local currency charge process using the debit card is the same as the process shown in FIG. 6, except that the debit management device 53 executes the payment process and the authentication process.

<Charging process of local currency using code information>
Except for the following points, it is the same as the charge processing of local currency using electronic money.
(1) In step A22, the currency charging device 11 acquires the ordinary currency management information by reading the code information displayed on the display unit of the user terminal. (2) The code management device 54 executes the payment process.

When charging the local currency using the code information, the method is not necessarily limited to the method in which the currency charging device 11 reads the code information from the user terminal.

First, the currency charging device 11 acquires local currency management information from the admission ticket for the World's Fair. Then, when the amount of the ordinary currency before the exchange or the amount of the local currency after the exchange is specified through the display operation unit 101, the control unit 140 receives the local currency management information and the amount of the ordinary currency before the exchange or after the exchange. Code information including one of the amounts of the local currency of is generated, and the generated code information is displayed on the display operation unit 101.

Next, the user starts the application on the user terminal on which the predetermined application is installed, and reads the code information displayed on the display operation unit 101. Here, the predetermined application is an application necessary for using the service using the code information. In addition, the ordinary currency management information is stored in the user terminal on which the predetermined application is installed.

Next, when the type of ordinary currency is input to the user terminal, the user terminal makes a charge request to the management device 30. Here, the charge request is one of the type of ordinary currency, the local currency management information included in the code information, and the amount of ordinary currency before exchange or the amount of local currency after exchange included in the code information. And the ordinary currency management information stored in the user terminal are specified.

In the subsequent processing, the charge completion notification is sent not to the currency charging device 11 but to the user terminal that made the charge request, and the processing corresponding to step A26 is executed in the user terminal. The same process as when the charging device 11 reads the code information is performed.

<Payment processing using local currency>
When the payment terminal 21 acquires the price information of goods and services in the local currency from a barcode reader (not shown) and acquires the local currency management information from the admission ticket of the World Expo through the reader (not shown), it makes a payment request. This is performed for the management device 30. The settlement request specifies price information and local currency management information.

When the instruction unit 335 of the management device 30 receives the payment request, the instruction unit 335 issues a payment instruction to the local currency management device 40 to specify the price information and the local currency management information specified by the payment request. The settlement instruction is an instruction to subtract the balance of the account associated with the designated local currency management information based on the price information.

In the local currency management device 40, the update unit 430 performs payment processing when the price indicated by the price information included in the payment instruction is equal to or less than the balance corresponding to the local currency management information. The settlement process is a process of subtracting the balance corresponding to the local currency management information based on the price indicated by the price information. After that, the local currency management device 40 notifies the payment terminal 21 that the payment process has been completed via the management device 30. When the payment terminal 21 receives the notification of the completion of the payment process, the notification unit outputs a voice or the like to notify the user and the clerk of the completion of the payment process. If the price indicated by the price information included in the settlement instruction exceeds the balance corresponding to the local currency management information, the update unit 430 does not perform the settlement process and notifies the management device 30 of an error.

<Refund processing from local currency to electronic money>
FIG. 8 is a sequence diagram showing a refund process from the local currency to the electronic money executed by the currency charge system 1.

In the currency charging device 11, the code reader 103 acquires the local currency management information when the code information of the admission ticket for the World Expo is held over the code reader 103 by the user (step A41).

Subsequently, the control unit 140 requests the local currency management device 40 to refer to the balance of the account corresponding to the local currency management information acquired in step A41 (step A42).

When the regional currency management device 40 receives the balance reference request, the balance associated with the regional currency management information specified by the reference request is read (step C41), and the read balance is sent to the currency charging device 11. Notice.

Subsequently, the control unit 140 causes the display operation unit 101 to display the balance notified from the local currency management device 40 (step A43).

Next, when the user holds a predetermined screen of the electronic money compatible card or the user terminal over the reader / writer 102, the reader / writer 102 displays the ordinary currency management information stored in the electronic money compatible card or the user terminal. Acquire (step A44).

Then, when the type of the ordinary currency after the exchange and the amount of the local currency before the exchange or the amount of the ordinary currency after the exchange are specified through the display operation unit 101, the control unit 140 tells the management device 30. Request a refund (step A45). Here, the control unit 140 specifies the type of the ordinary currency after the exchange, the local currency management information, the ordinary currency management information, and the designated amount of the ordinary currency after the exchange or the amount of the local currency before the exchange. Make a refund request.

In the management device 30, the management information acquisition unit 331 acquires the local currency management information and the ordinary currency management information specified in the refund request. Then, the amount acquisition unit 333 acquires the amount specified in the refund request (step B41). Here, the amount acquisition unit 333 acquires the amount of the ordinary currency after the exchange or the amount of the local currency before the exchange.

Next, the calculation unit 334 calculates the amount of subtraction to the balance of the local currency and the amount of addition to the balance of the ordinary currency (step B42). Upon receiving the refund request, the rate determination unit 332 receives the refund request, and based on the type of the ordinary currency specified by the refund request, the exchange associated with the ordinary currency corresponding to the specified exchanged ordinary currency type. The reference value of the rate is read from the storage unit 310, and the exchange rate between the specified type of ordinary currency and the local currency is determined based on the read exchange rate reference value and various conditions. Then, the rate determination unit 332 outputs the determined exchange rate to the calculation unit 334. If the amount acquired by the amount acquisition unit 333 is the amount of the local currency before the exchange, the calculation unit 334 calculates the amount to be deducted from the balance of the local currency based on the amount of the local currency before the exchange, and determines the rate. The amount to be added to the balance of the ordinary currency is calculated based on the exchange rate between the local currency and the ordinary currency output from the part 332 and the amount of the local currency before the exchange. If the amount acquired by the amount acquisition unit 333 is the amount of the ordinary currency after the exchange, the calculation unit 334 indicates the exchange rate between the local currency and the ordinary currency output from the rate determination unit 332, and the exchange rate after the exchange. The amount to be deducted from the balance of the local currency is calculated based on the amount of the ordinary currency, and the amount to be added to the balance of the ordinary currency is calculated based on the amount of the exchanged ordinary currency.

Next, the instruction unit 335 gives a refund instruction to the local currency management device 40 to specify the local currency management information and the amount to be deducted from the balance of the local currency calculated by the calculation unit 334 (step B43). The refund instruction is an instruction to subtract the balance of the local currency associated with the designated local currency management information based on the subtraction amount.

In the local currency management device 40, the update unit 430 receives the refund instruction, and if the deduction amount to the balance of the local currency corresponding to the local currency management information is less than or equal to the balance corresponding to the local currency management information, the refund process is performed. (Step C42). Here, the update unit 430 updates the balance of the account corresponding to the local currency management information based on the subtraction amount specified by the refund instruction. When the refund process is completed, the electronic money management device 51 sends a refund completion notification to the management device 30 to notify that the refund process is completed. If the amount deducted from the balance of the local currency corresponding to the local currency management information exceeds the balance corresponding to the local currency management information, the update unit 430 does not perform refund processing and notifies the management device 30 of an error. I do.

Upon receiving the refund completion notification from the local currency management device 40, the instruction unit 335 of the management device 30 sends the electronic money management device 51 the ordinary currency management information and the additional amount of the ordinary currency calculated by the calculation unit 334. A designated refund instruction is given (step B44). The refund instruction is an instruction to add the balance of the ordinary currency associated with the designated ordinary currency management information.

In the electronic money management device 51, when the renewal unit receives the refund instruction, the renewal unit executes the refund process based on the refund instruction (step D41). Here, the update unit updates the balance of the account corresponding to the managed currency management information specified by the refund instruction based on the additional amount specified by the refund instruction.

When the refund process is completed, the electronic money management device 51 transmits a refund completion notice notifying the management device 30 that the refund process is completed.

When the management device 30 receives a refund completion notification from the electronic money management device 51, the control unit 330 refunds the amount of deduction to the balance of the local currency, the amount of the ordinary currency before the exchange, the currency type of the ordinary currency, and the like. The information regarding the processing is stored in the storage unit 310 in association with the local currency management information and the ordinary currency management information (step B45). Then, the control unit 330 sends a refund completion notification to the currency charging device 11.

When the currency charging device 11 receives the refund completion notification, the control unit 140 causes the display operation unit 101 to display a screen notifying that the refund processing from the local currency to the ordinary currency is completed (step A46).

<Refund processing for the amount of credit card that can be used from the local currency>
FIG. 9 is a sequence diagram showing a refund process for the available amount of the credit card from the local currency executed by the currency charge system 1.

In the currency charging device 11, the code reader 103 acquires the local currency management information by holding the code information of the admission ticket for the World Expo over the code reader 103 (step A51).

Subsequently, the currency charging device 11 and the local currency management device 40 perform processing related to the local currency balance inquiry (step W51). Step W51 corresponds to steps A42, C41, and A43 in FIG.

Next, when the user inserts the credit card into the card reader 104, the card reader 104 acquires the ordinary currency management information from the credit card (step A52). Then, the currency charging device 11, the management device 30, and the credit management device 52 perform processing related to credit card authentication (step W52). Step W52 corresponds to steps A33, A34, B31, and E31 in FIG.

The processing after the refund request (step A53) by the currency charging device 11 is derived from the difference in the characteristics of the use of electronic money and the use of credit cards, that is, whether to manage the balance or the available amount. Except, it is the same as steps A45, A46, B41-B45, C42 and D41 in the refund processing from the local currency to the electronic money.

The refund processing from the local currency to the balance of the debit card is the same as the processing shown in FIG. 8 except that the debit management device 53 executes the refund processing and the authentication processing.

<Refund processing from local currency to the account associated with the code information>
Except for the following points, it is the same as the refund process for electronic money.
(1) In step A44, the currency charging device 11 acquires the ordinary currency management information by reading the code information displayed on the display unit of the user terminal. (2) The code management device 54 executes the refund process.

When refunding from the local currency to the account associated with the code information, the method is not necessarily limited to the method in which the currency charging device 11 reads the code information from the user terminal.

First, the currency charging device 11 acquires local currency management information from the admission ticket for the World's Fair. Then, the currency charging device 11 and the local currency management device 40 perform the processing corresponding to steps A42, C41, and A43, that is, the reference processing of the balance of the local currency associated with the acquired local currency management information. Then, when the amount of the local currency before the exchange or the amount of the ordinary currency after the exchange is specified through the display operation unit 101, the control unit 140 receives the local currency management information and the amount of the ordinary currency before the exchange or after the exchange. Code information including one of the amounts of the local currency is generated, and the display operation unit 101 is made to display the generated code information.

Next, the user reads the code information displayed on the display operation unit 101 on the user terminal. Then, the user inputs the type of the exchanged ordinary currency into the user terminal.

After that, the user terminal makes a refund request to the management device 30. Here, the refund request is one of the type of ordinary currency, the local currency management information included in the code information, and the amount of ordinary currency after exchange or the amount of local currency before exchange included in the code information. And specify the ordinary currency management information stored in the user terminal.

In the subsequent processing, the currency charging device 11 manages the ordinary currency except that the refund completion notification is sent to the user terminal that requested the refund and the processing corresponding to step A46 is executed on the user terminal. The same process as when reading information is performed.

In the above description, the ordinary currency management information and the regional currency management information are stored or printed in different media, but the ordinary currency management information and the regional currency management information are stored in the same medium. Alternatively, it may be printed. For example, the ordinary currency management information and the local currency management information may be stored in a user terminal such as a smartphone. In this case, for example, the user terminal stores the ordinary currency management information corresponding to the electronic money account, and the electronic admission ticket for the World Expo is downloaded. Therefore, the user displayed the screen of the user terminal on which the ordinary currency management information corresponding to the electronic money account was displayed and the electronic admission ticket for the World Exposition on the currency charging device 11. By holding the screen of the user terminal over, the currency charging device 11 can acquire the ordinary currency management information and the local currency management information. Therefore, the user can perform the charge procedure to the local currency and the refund procedure from the local currency with one medium.

As described above, the ordinary currency management information and the regional currency management information may be stored in one card. For example, as described above, it is assumed that a card compatible with electronic commerce can also serve as an admission ticket for the World Expo. In this case, for example, it is assumed that the electronic money compatible card is issued as a common card in cooperation with the electronic money business operator and the local currency business operator.

The currency charge system 1 of the present embodiment may perform refund processing from the local currency to cash.

Further, at the time of charging the local currency using the ordinary currency and refunding from the local currency to the ordinary currency, the management device 30 of the currency charge system 1 calculates the charge fee and the refund fee, and uses the calculated charge fee and the refund fee as the calculated charge fee and the refund fee. Based on this, charge instructions, refund instructions, payment instructions, payment instructions and refund instructions can be given.

<Determination of exchange rate>
Next, an example of a method of determining the exchange rate between the ordinary currency and the local currency by the rate determination unit 332 will be described. In this specification, the exchange rate is defined as the ratio of the amount of ordinary currency to the amount of local currency. For example, when the exchange rate between the Japanese currency and the local currency is "1", the Japanese currency "100 yen" and the local currency "100 BPC" are exchanged. When the exchange rate between the US currency and the local currency is "0.01", the US currency "1 dollar" and the local currency "100 BPC" are exchanged.

(A) Weather The weather information acquisition unit 340 acquires the current weather information from the server that provides the weather information via the network W. The weather information is, for example, "The weather as of 12:00 on May 1, 2025 is sunny", "The weather as of 12:00 on May 2, 2025 is cloudy and strong wind", and so on. The date and time correspond to the weather.

The rate determination unit 332 sets the exchange rate lower than the reference value of the exchange rate when the weather information on the date and time when the charge request of the local currency is received includes information indicating bad weather such as rain, snow, and strong wind. If the weather information on the date and time when the refund request to the ordinary currency is received includes information indicating bad weather, the exchange rate can be used as the reference value of the exchange rate.

Lowering the exchange rate is advantageous to those who charge when charging local currencies. For example, suppose that the reference value of the exchange rate between the Japanese yen and the local currency BPC is "1". If the exchange rate between Japanese yen and local currency BPC is determined to be "1", you can charge "100 BPC" using "100 yen". If the exchange rate between Japanese yen and local currency BPC is determined to be "0.8", which is lower than the standard value, "125 BPC" can be charged using "100 yen". In addition, if the exchange rate is increased, it is advantageous for those who request a refund when returning the local currency to the ordinary currency and refunding it. For example, if the exchange rate between Japanese yen and local currency BPC is determined to be "1", "100 BPC" can be refunded as "100 yen". If the exchange rate between Japanese Yen and local currency BPC is determined to be "1.25", "100 BPC" can be refunded as "125 Yen".

The rate determination unit 332 can determine the exchange rate in favor of the person who charges the local currency when charging the local currency using ordinary currency when the weather is bad, so that even in bad weather, the exchange rate can be set for the World Expo. Visitors can be encouraged and the use of local currencies can be encouraged.

(B) Money Business Campaign The period designation unit of each management device 51 to 54 designates a predetermined period. For example, suppose company A, which is a credit company, sets a campaign period from "April 13 to May 13, 2025" in order to encourage the use of the credit card provided by company A. Then, when the period of "April 13, 2025 to May 13, 2025" is input to the credit management device of the company A, the period designation unit designates the input period as a predetermined period. The predetermined period may be composed of discontinuous periods such as "every Tuesday in May 2025", "during May 2025 and from 12:00 to 20:00", and the like. ..

The rate determination unit 332 of the management device 30 acquires a predetermined period designated by the period designation unit from the credit management device of the company A. Then, in the rate determination unit 332, the ordinary currency management information specified in the charge request is the information managed by the credit management device of the company A, and the date and time when the charge request is received is the acquired predetermined period. When included in, the exchange rate can be lower than the reference value of the exchange rate. The rate determination unit 332 included the date and time when the refund request from the local currency to the ordinary currency was received within a predetermined period, and the ordinary currency management information was the information managed by the credit management device of the company A. Even so, the exchange rate can be used as the reference value of the exchange rate.

When the campaign period is specified by the money operator of the ordinary currency, the rate determination unit 332 charges the period when the local currency is charged by using the service provided by the money operator who specified the period. The exchange rate can be determined to the advantage of the person. Therefore, the use of services provided by money businesses can be promoted, and the use of local currencies can be promoted.

(C) In the storage unit 310 of the event management device 30, information about the event to be held at the World Expo is stored in association with the date. In the storage unit 310, for example, when an event commemorating the United States of America is held on July 4, 2025, the US dollar, which is the currency of the United States of America, and July 4, 2025 are stored in association with each other. It may have been.

The rate determination unit 332 indicates that the date when the charge request is received corresponds to the event date and the type of ordinary currency before exchange specified by the charge request is associated with the event date. The exchange rate can be lower than the reference value of the exchange rate. Further, the rate determination unit 332 indicates that the date when the refund request is received corresponds to the event date, and the type of ordinary currency after exchange specified by the refund request is associated with the event date. Even so, the exchange rate can be determined as the reference value of the exchange rate.

That is, on the date of the event, the exchange rate can be determined to favor the charge of the local currency from the particular common currency associated with the event. Therefore, on the day of the event, it is possible to encourage those who use a specific ordinary currency to visit the World's Fair. It can also promote the use of local currencies.

(D) The counting unit 341 of the number of visitors management device 30 is the number of local currency management information sent from the currency charging device 11, the mobile currency charging device 12, and the user terminal to the management device 30 together with the charge request, that is. , Count the number of money media used to charge local currencies. Here, the number of local currency management information is not the total number of charge requests received by the management device 30.

When the number counted by the counting unit 341 is equal to or less than the threshold value for a predetermined number of days, the rate determining unit 332 can lower the exchange rate when the charge request is received to be lower than the reference value of the exchange rate. Further, the rate determination unit 332 can use the exchange rate when the refund request is received as the reference value of the exchange rate even if the number counted by the counting unit 341 is equal to or less than the threshold value for a predetermined number of days.

Since the number counted by the counting unit 341 can be considered to correspond to the number of visitors to the World Expo, the rate determination unit 332 charges the local currency using the ordinary currency when the number of visitors continues to be small. The exchange rate can be determined to the advantage in some cases. Therefore, even if the number of visitors to the World Expo continues to be small, it is possible to encourage visitors to the World Expo and increase the number of visitors. It can also promote the use of local currencies.

(E) Total usage of local currency The payment information acquisition unit 342 of the management device 30 acquires the price information (that is, the payment amount) specified by the payment request sent from the payment terminal 21 to the management device 30. The total payment amount calculation unit 343 of the management device 30 calculates the total amount of the payment amount acquired by the payment information acquisition unit 342 on a daily basis.

When the total settlement amount is equal to or less than the threshold value for a predetermined number of days, the rate determination unit 332 can lower the exchange rate when the charge request is received to be lower than the reference value of the exchange rate. Further, the rate determination unit 332 can use the exchange rate at the time of receiving the refund request as the reference value of the exchange rate even if the total settlement amount is equal to or less than the total amount threshold value for a predetermined number of days.

In this way, if the usage amount of the local currency continues to be low, the rate determination unit 332 can determine the exchange rate so as to be advantageous when charging the local currency using the ordinary currency. .. Therefore, the use of local currencies can be promoted.

(F) In the rate determination unit 332 of the amount management device 30 of the currency charging device, the deposit unit 111 accepts the deposit of cash in the ordinary currency (for example, US dollars) before the exchange, and the currency charging device 11 determines the type of the ordinary currency. When a charge request for specifying (here, US dollars) is sent, the rate determination unit 332 acquires the amount of money stored in the storage unit 130 of the currency charging device 11 for each type of ordinary currency.

Then, when the amount of currency corresponding to the type of ordinary currency (here, US dollars) specified by the charge request is equal to or less than the lower limit, the rate determination unit 332 determines the ordinary currency (here, US dollars). The exchange rate from dollars) to local currencies can be determined to be smaller than the reference value. The lower limit threshold value referred to here is a value that serves as a guide when determining whether or not cash replenishment is necessary.

When the amount of money in the currency charging device 11 is insufficient, it is necessary to replenish the currency charging device 11 with cash in order to prevent the shortage of fishing bills. In general, it is often expensive to replenish and collect cash using a transportation company. Since the rate determination unit 332 can determine the exchange rate in favor of the person performing the charge when the charge is performed using the cash of the currency having a small amount of money in the currency charging device 11, the currency. The user is urged to replenish the currency with a small amount of money in the charging device 11. Therefore, since the frequency of replenishing cash to the currency charging device 11 using the transportation company can be reduced, the cost for using the transportation company can be reduced.

Further, in the rate determination unit 332, the amount of currency corresponding to the type of ordinary currency (for example, US dollars) specified by the charge request is smaller than the upper limit threshold, and the ordinary currency is specified by the charge request. Among currencies different from the type of currency, if there is a currency with an existing amount equal to or higher than the upper limit threshold value, the exchange rate from the ordinary currency to the local currency can be determined to be smaller than the reference value. The upper limit threshold value referred to here is a value that serves as a guide for determining whether or not to collect cash.

For example, in the currency charging device 11, it is assumed that the US dollar is below the upper threshold and the euro is above the upper threshold. It is also assumed that the user has US dollars and euros as cash respectively. In this case, it is more advantageous for the user to charge the local currency using the cash of US dollars than to charge the local currency using the cash of the euro.

If there is a currency with a large amount of money in the currency charging device 11, that is, if there is a currency with a high filling rate in the cash storage unit, it is necessary to use a police company to collect the currency with a high filling rate. As mentioned above, it is often costly to replenish and collect cash using a transportation company in general. The rate determination unit 332 is advantageous to the person who charges when there is a currency with a large amount of money in the currency charging device 11 and when the charge is made using cash of a currency other than the currency with a large amount of money. The exchange rate can be determined. Therefore, it is possible to suppress the payment to the currency charging device 11 for the currency having a large amount of money in the currency charging device 11. Therefore, since the frequency of collecting cash from the currency charging device 11 using the transportation company can be reduced, the cost for using the transportation company can be reduced.

(G) In the storage unit 310 of the charge amount management device 30 for each individual of the local currency, the amount added to the balance of the local currency is stored in association with the local currency management information and the ordinary currency management information.

When the rate determination unit 332 receives a refund request from the local currency to the ordinary currency, the exchange rate is exchanged as the amount added to the local currency associated with the local currency management information specified by the refund request is larger. It can be higher than the reference value of the rate. When the rate determination unit 332 receives a charge request from the ordinary currency to the local currency, the rate determination unit 332 can determine the exchange rate as the reference value of the exchange rate.

That is, the rate determination unit 332 determines the exchange rate so as to be advantageous when refunding from the local currency to the common currency for those who have exchanged the common currency for more local currencies. Therefore, the use of local currencies can be promoted.

(H) Individual usage amount of local currency The payment information acquisition unit 342 of the management device 30 sets the price information (that is, the payment amount) and the local currency specified by the payment request sent from the payment terminal 21 to the management device 30. Get management information. The cumulative value calculation unit 344 calculates the cumulative value of the settlement amount for each local currency management information based on the settlement amount acquired by the settlement information acquisition unit 342.

When the rate determination department receives a refund request from the local currency to the ordinary currency, the larger the cumulative value corresponding to the local currency management information specified by the refund request, the higher the exchange rate with respect to the reference value of the exchange rate. can do. When the rate determination unit 332 receives a charge request from the ordinary currency to the local currency, the rate determination unit 332 can determine the exchange rate as the reference value of the exchange rate.

That is, the rate determination unit 332 determines the exchange rate so that the larger the total amount of the local currency used, the more advantageous it is when refunding from the local currency to the ordinary currency. Therefore, the use of local currencies can be encouraged.

(I) The exchange rate at the time of charging and the exchange rate at the time of refund are the same. The reference value of the exchange rate associated with the type may be determined as it is as the exchange rate.
