  ADVANTAGE OF THE INVENTION According to this invention, it can recover efficiently by performing retry when there is no response after transmitting money amount change information to a money terminal.

(1) Outline of Embodiment After transmitting money amount change information to an electronic money card, the electronic money terminal transmits retry information to the electronic money card when there is no response.
When the electronic money card receives the amount change information, the electronic money card responds by performing the amount change process. On the other hand, when the retry information is received, the electronic money card confirms whether or not the amount change processing has already been performed. If the amount change processing has been performed, the electronic money card responds without performing the amount change processing. If the change process has not been performed, the money amount change process is performed and a response is made.

The electronic money terminal repeatedly transmits retry information to the electronic money card until the retry is successful during the retry period.
The retry period includes a first period and a second period following the first period, and the electronic money terminal does not accept a retry stop request in the first period, and in the second period, Stop retry by request to stop.

Value is electronic data associated with a monetary value in the electronic money system 1 and has an amount as an attribute, and an increase or decrease in the amount causes a transfer of exchange value similar to that of currency.
At the time of charging, the price for the charged amount is collected from the customer, and this is distributed to the member stores according to the value settlement amount, so that the value and the currency are matched.
The concept of value can also include exchange value that can be exchanged for goods and services such as points.

When the electronic money card 6 receives the money amount change information from the electronic money terminal 8, the electronic money card 6 performs the money amount changing process using the received information, and sends a completion response to the electronic money terminal 8 that the money amount changing process is completed. This response is made by sending a completion notification from the electronic money card 6 to the electronic money terminal 8.
Further, when the electronic money card 6 receives the retry information from the electronic money terminal 8, the electronic money card 6 confirms whether or not the amount change processing is completed. If the amount change processing is completed, the electronic money card 6 can change the value balance. If the amount change processing is not completed, the completion response is sent to the electronic money terminal 8 after the amount change processing is performed on the value balance.

If the electronic money terminal 8 does not receive a completion response for a predetermined time after sending the money amount change information to the electronic money card 6, the electronic money terminal 8 determines that it is unknown whether or not the money amount change process has been performed on the electronic money card 6. Trial information is generated and transmitted to the electronic money card 6.
The electronic money terminal 8 waits for a completion response for a predetermined time after transmitting the retry information to the electronic money card 6. When there is a completion response, the electronic money terminal 8 ends the process, and when there is no completion response, The retry information is transmitted to the electronic money card 6 again.
The electronic money terminal 8 repeats the above retry process until a completion response is received during a preset retry period.

In this way, the electronic money terminal 8 includes retry information transmitting means for transmitting retry information to the money terminal (electronic money card 6) when a response (completion response) is not received within a predetermined time. I have.
If the electronic money terminal 8 does not receive a response to the effect that the amount change processing is completed within a predetermined time after transmitting the retry information, the response receiving means responds during the retry period (completion response). ), The retry information is repeatedly transmitted to the money terminal (electronic money card 6).

The retry period is composed of a first period followed by an indefinite second period. The first period is set in advance in the electronic money terminal 8 such as 10 seconds, for example.
The electronic money terminal 8 is provided with a stop accepting unit that accepts a request for stopping the retry process from a person in charge of operation by using a stop button or the like, for example, but during the first retry period, a stop request is issued. Even if it is received, the retry is continued without executing this, and in the second period, the stop request is received and the retry process is stopped.

As described above, by providing a period (first period) in which the stop request is not accepted after the retry process is started, the retry process can be reliably performed at least a predetermined number of times.
In addition, by providing an indefinite period (second period) for accepting the stop request, the retry process can be continued while the person in charge of operation or the customer determines that it is necessary.

The electronic money terminal 8 automatically shifts to a retry period when there is no completion response to the money amount change information. At that time, the electronic money terminal 8 performs a retry process by display or voice. To the person in charge and the customer to prevent the customer from taking the electronic money card 6 by misunderstanding that the amount change processing has been completed.
Further, the electronic money terminal 8 stores the processing content with the electronic money card 6 as usage log data, and transmits it to the electronic money server 2 by batch processing, for example, once a day.

The EEPROM 25 is a ROM capable of writing and erasing information. Information stored in the EEPROM 25 is maintained even when power is not supplied to the electronic money card 6.
The EEPROM 25 stores an electronic money program for causing the electronic money card 6 to function as an electronic money card, as well as an electronic money function unit ID which is ID information for identifying a value balance, log data, and IC chip. An electronic money storage unit 29 for storing various data such as is formed.

Further, the CPU 21 stores information indicating whether or not the money amount change processing is completed by the money amount change information received from the electronic money terminal 8 as log data in the EEPROM 25, and when the retry information is received, the money amount change information has already been received. Used to confirm whether or not
This is because the customer may remove the electronic money card 6 from the electronic money terminal 8 at the time of retry, so that the memory is retained even when the power supply to the electronic money card 6 is interrupted. It is.

FIG. 3 is a block diagram schematically showing a functional configuration of the electronic money card 6 formed when the CPU 21 executes the electronic money program.
The electronic money storage unit 29 formed in the EEPROM 25 stores an electronic money function unit ID, a value balance, log data, and the like.

The value balance is the balance of the value currently stored, and the electronic money card 6 has a settlement capability corresponding to this balance.
As described above, the electronic money storage unit 29 functions as an amount storage unit that stores the amount of money as electronic data (value).
The log data is log data in which processing contents communicated with the electronic money terminal 8 and the electronic money server 2 are recorded.

The value processing unit 28 is an information processing unit that executes various commands.
The commands include amount change information, retry information, ID reference command, balance reference command, and the like.
The amount change information is a command that causes the value processing unit 28 to perform the amount change process.
When executing the amount change process, the value processing unit 28 increases or decreases the value balance by the amount specified by the amount change information, sends a completion response to the electronic money terminal 8, and creates log data.
In this way, the value processing unit 28 performs the amount change process on the amount stored in the electronic money storage unit 29 using the amount change information received from the electronic money terminal 8, and a response that the amount change process is completed. It functions as a money amount changing means.

By the way, the amount change information can be configured using, for example, an addition command, a subtraction command, an overwrite command, or the like.
The addition command is a command for increasing the value balance by the amount specified by the parameter accompanying the addition command.
On the other hand, the subtraction command is a command for reducing the value balance by the amount specified by the parameter accompanying the subtraction command.
For example, when the value balance is 5000 yen and the settlement amount is 1000 yen, the electronic money terminal 8 generates a subtraction command for reducing 1000 yen and transmits it to the electronic money card 6.
In the electronic money card 6, the value processing unit 28 executes this subtraction command to update the value balance to 5000 yen-1000 yen = 4000 yen. The same applies to the addition command.

The overwrite command is a command for overwriting the value balance with the amount specified by the parameter accompanying the overwrite command.
When using the overwrite command as the amount change information, the electronic money terminal 8 calculates the value balance after settlement and charging, and causes the value processing unit 28 to overwrite the value balance in the electronic money storage unit 29 with this amount.
For example, consider a case where the value balance is 5000 yen and the settlement amount is 1000 yen.
The electronic money terminal 8 reads the current value balance of 5000 yen from the electronic money card 6 and calculates a balance of 5000 yen-1000 yen = 4000 yen after settlement.
Then, the electronic money terminal 8 generates an overwrite command for overwriting the value balance to 4000 yen and transmits it to the electronic money card 6.
In the electronic money card 6, the value processing unit 28 executes this overwrite command and updates the value balance to 4000 yen.

  The amount change information may be configured by an addition command and a subtraction command, may be configured by using an overwrite command in the case of charge, a subtraction command in the case of payment, or an addition command in the case of charge. Use and subtraction may be configured using an overwrite command, or charging and settlement may be configured to use an overwrite command.

Retry information is an amount change information accompanied by a retry parameter indicating that it is related to a retry, and is composed of an overwrite command, an addition command, a subtraction command, etc., similar to the amount change information. Yes.
That is, for example, when an addition command is used as the amount change information, the retry information is obtained by attaching a retry parameter to the addition command.
An operation method is also possible in which an addition command is used for the amount change information and an overwrite command is used for the retry information.

When the value processing unit 28 receives retry information (amount change information accompanied by a retry parameter), the value processing unit 28 executes the amount change information in a retry mode.
That is, the value processing unit 28 confirms whether or not the amount change process has been completed. If the amount change process has already been completed, the value processing unit 28 sends a completion response to the electronic money terminal 8 without performing the amount change process. If the amount change process has not been completed, the amount change process is performed and a completion response is sent to the electronic money terminal 8.

  As described above, the value processing unit 28 confirms whether or not the amount change processing is completed for the amount stored in the electronic money storage unit 29. If it is confirmed that it has not been completed, it has a function as retry means for performing a money amount change process and sending a response that the money amount change process is completed.

The ID reference command is a command for causing the value processing unit 28 to read the electronic money function unit ID. When the ID reference command is input, the value processing unit 28 obtains the electronic money function unit ID from the electronic money storage unit 29. Read and output.
The balance reference command is a command for causing the value processing unit 28 to read the value balance, and when the balance reference command is input, the value processing unit 28 reads the value balance from the electronic money storage unit 29 and outputs it.

This usage log data is transmitted to the electronic money server 2 by batch processing performed by the CPU 31.

Here, the usage log data will be described.
The usage log data includes “electronic money function unit ID”, “transaction amount”, “transaction date / time / minute / second”, “member store ID”, “response flag”, and other items.
In the “electronic money function unit ID”, the electronic money function unit ID of the electronic money card 6 processed by the electronic money terminal 8 is recorded.
In “Transaction Amount”, the amount of payment processing or charge processing and the amount of payment processing or charge processing are recorded.

In “transaction date / time / minute / second”, the year / month / day / hour / minute / second when the electronic money terminal 8 performed processing with the electronic money card 6 is recorded.
In the “member store ID”, a member store ID which is ID information of the member store in which the electronic money terminal 8 is installed is recorded.

In the “response flag”, whether or not a completion response is received from the electronic money card 6 is recorded as flag information.
When the electronic money terminal 8 receives a completion response from the electronic money card 6 by the amount change process or the retry process, it sets the “response flag” to “complete” and sets the retry period without receiving these. If stopped, set to “Incomplete”.

FIG. 6 is a diagram illustrating an example of a hardware configuration of the electronic money server 2.
The electronic money server 2 is configured by connecting a CPU 51, a ROM 52, a RAM 54, a communication control unit 53, a storage unit 55, and the like through a bus line.
The CPU 51 is a central processing unit that performs various types of information processing according to a predetermined program. In the present embodiment, usage log data is received from the electronic money terminal 8 and totalization processing is performed.

The ROM 52 is a read-only memory, and stores basic programs and parameters for operating the electronic money server 2.
The RAM 54 is a readable / writable memory, and provides a working memory for the CPU 51, loads and stores programs and data stored in the storage unit 55, and the like.
The communication control unit 53 is a control unit for communicating with the electronic money terminal 8.

The storage unit 55 is configured by using a large-capacity storage device such as a hard disk, and includes a program storage unit 56 that stores various programs, a data storage unit 57 that stores data, and the like.
The program storage unit 56 stores an OS that is a basic program for causing the electronic money server 2 to function, a program for analyzing and summing usage log data, and other programs.
The data storage unit 57 stores a member store database storing member store information, a use log data database of use log data received from the electronic money terminal 8, and the like.

The electronic money server 2 aggregates the usage log data stored in the usage log data database about once a month, for example.
When the usage log data is totaled, the electronic money server 2 totals those whose “response flag” is set to “complete”.
Aggregation is performed by summing the amounts charged for each member store and summing the amounts settled by value.
The amount charged by the member store is settled to the electronic money center from the member store, and the settled amount is settled to the member store from the electronic money center.
Regarding the usage log data whose “response flag” is “incomplete”, the electronic money center deals individually.

Next, a procedure in which the electronic money terminal 8 causes the electronic money card 6 to perform the money amount changing process will be described with reference to the flowchart of FIG.
The following processing is performed in cooperation with the CPU 21 of the electronic money card 6 and the CPU 31 of the electronic money terminal 8.
In the following, a case where the settlement process is performed will be described as an example.

First, the customer places the electronic money card 6 over the reader / writer unit 39 so that the electronic money card 6 and the electronic money terminal 8 can perform wireless communication.
On the other hand, the person in charge of the member store inputs the payment amount to the electronic money terminal 8.
Next, the electronic money terminal 8 detects the electronic money card 6, starts wireless communication with the electronic money card 6, and performs pre-processing on the electronic money card 6 (step 5).
In this pre-processing, the electronic money terminal 8 transmits an ID reference command, a balance reference command, and the like to the electronic money card 6, and the electronic money function unit ID of the electronic money card 6 and the current value balance are transmitted from the electronic money card 6. (That is, the value balance before the amount change process) is acquired and stored in the RAM 34 (FIG. 5) or the like.

Next, the electronic money terminal 8 generates amount change information for reducing the value balance by the payment amount and transmits it to the electronic money card 6 (step 10).
The electronic money card 6 receives the amount change information from the electronic money terminal 8 and uses this to reduce the value balance stored in the electronic money storage unit 29 by the amount of payment.
When the money amount change process is completed, the electronic money card 6 transmits a completion response to the electronic money terminal 8 and responds to the electronic money terminal 8 (step 15).

  The electronic money terminal 8 does not receive the completion response because the electronic money card 6 fails to receive the money amount change process, or the money amount change process is completed but the completion response transmission fails. Therefore, in FIG. 7, step 15 is indicated by a dotted line. The same applies to step 30 and step 50 below.

After transmitting the money amount change information to the electronic money card 6, the electronic money terminal 8 waits for a completion response from the electronic money card 6 for a predetermined time.
When a completion response is received from the electronic money card 6 during a predetermined period (step 20; Y), the electronic money terminal 8 generates and stores usage log data in which the “response flag” is set to “complete” ( Step 70), the process ends.

On the other hand, when a completion response is not received from the electronic money card 6 within a predetermined time (step 20; N), the electronic money terminal 8 transmits retry information to the electronic money card 6 (step 25).
Further, the electronic money terminal 8 starts measurement of the first period, and does not accept a retry stop request during this period.

  When the electronic money card 6 receives the retry information from the electronic money terminal 8, the electronic money card 6 confirms whether or not the money amount changing process is completed in step 15. If it is transmitted to the terminal 8 and the amount change process is not completed, the retry information is executed to perform the amount change process, and a completion response is transmitted to the electronic money terminal 8 (step 30).

After transmitting the retry information to the electronic money card 6 in step 25, the electronic money terminal 8 waits for a completion response from the electronic money card 6 for a predetermined time.
When a completion response is received from the electronic money card 6 during a predetermined time (step 35; Y), the electronic money terminal 8 generates and stores usage log data in which the “response flag” is set to “complete” ( Step 70), the process ends.

On the other hand, when the completion response is not received from the electronic money card 6 within a predetermined time (step 35; N), the electronic money terminal 8 determines whether or not the first period has elapsed since the retry was started. Judgment is made (step 40).
If the first period has not elapsed (step 40; N), the electronic money terminal 8 returns to step 25 and transmits retry information to the electronic money card 6 without accepting the stop request (step 25). ).
When the first period has elapsed (step 40; Y), the electronic money terminal 8 shifts to the second period, makes it possible to accept a retry stop request, and sends retry information to the electronic money. Transmit to the card 6 (step 45).

  Upon receiving the retry information from the electronic money terminal 8, the electronic money card 6 confirms whether or not the amount change processing has already been completed by the amount change processing in step 15 or the retry processing in step 30, and the amount change processing Is completed, a completion response is transmitted to the electronic money terminal 8, and if the amount change process is not completed, retry information is executed to perform the amount change process, and a completion response is sent to the electronic money terminal 8. Is transmitted (step 50).

After transmitting the retry information to the electronic money card 6 in step 45, the electronic money terminal 8 waits for a completion response from the electronic money card 6 for a predetermined time.
When a completion response is received from the electronic money card 6 during a predetermined time (step 55; Y), the electronic money terminal 8 generates and stores usage log data in which the “response flag” is set to “complete” ( Step 70), the process ends.

On the other hand, when the completion response is not received from the electronic money card 6 within a predetermined period (step 55; N), the electronic money terminal 8 confirms whether or not a retry stop is requested from an operator or the like ( Step 60).
When the stop is not requested (step 60; N), the electronic money terminal 8 returns to step 45 and transmits retry information to the electronic money card 6 (step 45).
When the stop request is made (step 60; Y), the electronic money terminal 8 stops the retry process, prints a confirmation receipt (described later) (step 65), and further sets the “response flag” to “incomplete”. ”Is generated and stored (step 70), and the process ends.

The above is a case where payment is made with the electronic money card 6, but the electronic money terminal 8 also performs a retry in the same manner when charging the electronic money card 6.
That is, the electronic money terminal 8 transmits the money amount change information for charging to the electronic money card 6 and then waits for a completion response from the electronic money card 6. If not received, retry information is sent repeatedly.
When retrying charging, the electronic money terminal 8 does not accept a stop request in the first period and accepts a stop request in the second period.
If the electronic money terminal 8 receives the completion response, the electronic money terminal 8 generates usage log data with the “response flag” set to “completed”. If the electronic money terminal 8 does not receive the completion response, the electronic money terminal 8 sets the “response flag” to “not yet”. Use log data that is “completed” is generated.

Next, the confirmation receipt will be described with reference to FIG.
The electronic money terminal 8 prints a confirmation receipt when the retry is stopped. As shown in FIG. 8, the confirmation receipt includes “settlement amount”, “value balance before settlement”, “electronic money function unit ID”, “terminal ID”, and other items.

The “settlement amount” is an amount related to settlement. In the case of charge, this item is “charge amount”, and the amount related to charge is printed.
The “value balance before settlement” is the value balance before the electronic money card 6 performs the amount change processing, and is read from the electronic money card 6 by the electronic money terminal 8 in step 5 of FIG.
In the case of charge, this item is “value balance before charge”, and the amount before the amount change processing is printed.
The “electronic money function unit ID” is the electronic money function unit ID of the electronic money card 6, and the “terminal ID” is the terminal ID of the electronic money terminal 8.

The confirmation receipt can be used for confirming whether or not the money change information has been executed by the electronic money card 6 by an operator in the following manner.
First, when a confirmation receipt is printed on the electronic money terminal 8, the person in charge of the operation confirms the value balance of the electronic money card 6 before the amount change processing based on the “value balance before settlement” described therein.
Then, the person in charge of the operation operates the electronic money terminal 8 to read the current value balance from the electronic money card 6 and compares it with the value balance printed on the confirmation receipt.

In the case where the two match by comparison, the person in charge of the operation determines that the amount change processing has not been performed on the electronic money card 6, and the current value balance is smaller than the value balance before the amount change processing by the amount of payment. The electronic money card 6 determines that the money amount change process has been performed. Thereafter, the person in charge of the operation performs a procedure in accordance with the business rules.
Further, the customer can refer to the contents described in the confirmation receipt when making an inquiry to the electronic money center.
In the present embodiment, the electronic money terminal 8 has printed the value balance before the amount change processing on the confirmation receipt, but may present it by other methods such as displaying it on a display device.

According to the embodiment described above, the following effects can be obtained.
(1) The electronic money terminal 8 can retry when the money change information is transmitted to the electronic money card 6 and there is no response from the electronic money card 6.
(2) In the retry period, by providing a first period in which the suspension is not accepted and a second period in which the suspension is accepted following the first period, the electronic money terminal 8 performs the retry at least once. It can be carried out.
(3) By making the second period indefinite, the operator and the customer can retry as many times as desired.
(4) When retrying is stopped, in order to print the value balance before sending the amount change information on the confirmation receipt, the operator inquires the value balance of the electronic money card 6 to inquire the electronic money card 6 It is possible to confirm whether or not the money amount change process has been performed.

(Modification 1)
Next, a modification of the present embodiment will be described.
The electronic money terminal 8 according to the present embodiment automatically inquires the value balance of the electronic money card 6 when the retry is not successful in the first period.
Then, the electronic money terminal 8 determines whether or not the electronic money card 6 has performed the amount change process by comparing the value balance before the amount change information is transmitted with the value balance after the retry stop. If the change process is not performed, the money amount change information is transmitted to the electronic money card 6 again.

FIG. 9 is a flowchart for explaining a procedure by which the electronic money terminal 8 of the first modification causes the electronic money card 6 to perform the money amount changing process.
Note that the same step numbers are assigned to the same processes as those in the flowchart of FIG. 7 to simplify the description.
Steps 5 to 40 are the same as those in the above-described embodiment.
The electronic money terminal 8 reads the value balance from the electronic money card 6 in step 5, but in this way, the electronic money terminal 8 receives the value change information from the money terminal (electronic money card 6) before sending the amount change information. First money acquisition means for acquiring the money stored in the money terminal is provided.

The electronic money terminal 8 of the present modification prints a confirmation receipt after the first period has elapsed in step 40 (step 65). The print contents are the same as those shown in FIG.
Next, the electronic money terminal 8 transmits a balance reference command to the electronic money card 6 and requests transmission of a value balance (step 75).

The electronic money card 6 receives a balance reference command from the electronic money terminal 8. Then, the electronic money card 6 executes the balance reference command, reads the value balance from the electronic money storage unit 29, and transmits it to the electronic money terminal 8 (step 80).
As described above, the electronic money terminal 8 includes second amount acquisition means for acquiring the amount stored by the money terminal from the money terminal (electronic money card 6) after stopping the transmission of the retry information.

The electronic money terminal 8 receives the value balance from the electronic money card 6 and displays it on the display device.
In this way, the electronic money terminal 8 presents the amount acquired by the first amount acquisition unit by printing it on the confirmation receipt, and presents it by displaying the amount acquired by the second amount acquisition unit on the display device. There is provided an amount presentation means.

The person in charge compares the value balance printed on the confirmation receipt (that is, the value balance before sending the amount change information) with the value balance displayed on the display device, so that the amount change process has been performed on the electronic money card 6. It can be determined whether or not.
At this point in time, the customer may consider that the payment has been completed and may remove the electronic money card 6 from the reader / writer unit 39. Therefore, if the amount change processing is not performed, the person in charge sends the electronic money card to the customer. 6 can be instructed to be installed in the reader / writer unit 39 again.

  In this modification, the value balance before sending the amount change information is printed on the confirmation receipt, and the value balance after stopping the retry is displayed on the display device. However, this may be reversed, or both are printed. Alternatively, both may be displayed on the display device, or may be presented by other methods such as voice.

  In this way, the electronic money terminal 8 displays the value balance, the value balance before sending the amount change information acquired in step 5 (hereinafter referred to as the previous balance), and the value balance after stopping the retry (hereinafter referred to as the following) The balance is compared, and it is determined whether or not the money amount change process has been performed on the electronic money card 6 as follows.

  That is, the electronic money terminal 8 compares the difference between the previous balance and the subsequent balance. If there is a difference (in this case, the subsequent balance is smaller than the previous balance), the electronic money card 6 performs the amount change process. If it is determined that there has been no difference (in this case, the previous balance and the subsequent balance have the same amount), it is determined that the amount change processing has not been performed on the electronic money card 6.

When there is no difference in the value balance (step 85; N), the electronic money terminal 8 shifts the processing to step 10 and transmits the amount change information to the electronic money card 6 again.
On the other hand, when there is a difference in the value balance (step 85; Y), the electronic money terminal 8 generates usage log data indicating that the amount change processing has been performed (step 70), and ends the processing.
In this way, the electronic money terminal 8 transmits the amount change information to the money terminal (electronic money card 6) again when the amounts acquired by the first amount acquisition means and the second amount acquisition means are equal. .
In this case, the amount change information transmitted from the electronic money terminal 8 to the electronic money card 6 may be retry information.

In addition, when the process is shifted from step 85 to step 10, the process may return to step 85 again.
In this case, for example, an infinite loop from Step 10 to Step 85 can be performed until the person in charge of the operation requests a stop.
It is also possible to count the number of times the loop from step 10 to step 85 is performed, and to stop when the predetermined number is reached.

  When the electronic money terminal 8 receives a completion response from the electronic money card 6, the electronic money terminal 8 generates use log data in which the “response flag” is set to “complete”, and stops the retry process without receiving the completion response. In this case, usage log data in which the “response flag” is set to “incomplete” is generated (step 70), and the process is terminated.

In this modification, when there is no difference in the value balance in step 85, the process automatically proceeds to step 10, but this may be configured to proceed to step 10 according to the judgment of the person in charge of the operation. .
In this case, if the person in charge of the operation determines that the amount change processing is not performed on the electronic money card 6 based on the difference between the previous balance and the subsequent balance, the processing of the electronic money terminal 8 proceeds to step 10 by his / her own judgment. Select whether to end or end.

In the modified example described above, the following effects can be obtained.
(1) When the retry is not successful, the electronic money terminal 8 can compare the previous balance and the subsequent balance by inquiring about the value balance. It can be determined whether or not the above has been performed.
(2) When it is determined by the value balance inquiry that the amount change process has not been performed on the electronic money card 6, the electronic money terminal 8 can cause the electronic money card 6 to perform the amount change process again. .
(3) Since the previous balance and the subsequent balance are presented to the person in charge of the operation using a confirmation receipt or display device, the person in charge of the operation can make necessary explanations to the customer and perform procedures in accordance with the business rules. Can do.

(Modification 2)
In this modification, the electronic money terminal 8 inquires about the value balance of the electronic money card 6 when a stop request is made in the second period in the embodiment described above.
The electronic money terminal 8 of this modification example performs the operations from step 5 to step 65 shown in FIG. 7, and then performs the operations from step 75 to step 85 shown in FIG.

That is, the electronic money terminal 8 of the present modification confirms the difference between the previous balance and the subsequent balance by making a balance inquiry of the electronic money card 6 after printing a confirmation receipt after a stop request for the second period is made. From this confirmation result, it is determined whether or not the money amount change process has been performed on the electronic money card 6.
If the electronic money terminal 8 determines that the amount change processing has been performed, the electronic money terminal 8 generates usage log data to that effect and ends the processing. If the electronic money terminal 8 determines that the amount change processing has not been performed, The processing is shifted to 10, and the amount change information is transmitted to the electronic money card 6 again.
