The commands include amount change information (consisting of an overwrite command, an addition command, a subtraction command, etc. described later), an ID reference command, a balance reference command, and the like.

  The amount change information is a command that causes the value processing unit 28 to increase or decrease the value balance stored in the electronic money storage unit 29 by the amount specified in the amount change information and record the processing history in the log data. Yes, it can be composed of an addition command, a subtraction command, an overwrite command, and the like described below.

The addition command is a command for causing the value processing unit 28 to increase the amount stored in the electronic money storage unit 29 by the amount specified by the parameter accompanying the addition command.
On the other hand, the subtraction command is a command that causes the value processing unit 28 to reduce the amount stored in the electronic money storage unit 29 by the amount specified by the parameter accompanying the subtraction command.
For example, when the value balance stored in the electronic money storage unit 29 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 terminal communication unit 27. Then, the value processing unit 28 executes this subtraction command and updates the balance of the value stored in the electronic money storage unit 29 to 5000 yen-1000 yen = 4000 yen.
The value processing unit 28 performs the same processing for the addition command.

The overwrite command is a command for causing the value processing unit 28 to overwrite the amount stored in the electronic money storage unit 29 with the amount specified by the parameter accompanying the overwrite command.
When the overwrite command is used as the amount change information, the electronic money terminal 8 calculates the value balance after addition / subtraction, 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 stored in the electronic money storage unit 29 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 terminal communication unit 27. Then, the value processing unit 28 executes this overwrite command, and updates the value balance stored in the electronic money storage unit 29 to 4000 yen.

The electronic money terminal 8 may be configured to use the addition / subtraction command described above, or may be configured to use an overwrite command.
Alternatively, an addition / subtraction command and an overwrite command can be combined.
For example, an addition command can be used for charging, an overwrite command can be used for settlement, or an overwrite command can be used for charging, and a subtraction command can be used for settlement.
In this manner, the value processing unit 28 functions as a money amount change information receiving unit that receives money amount change information from the money amount change information transmitting device (the electronic money terminal 8 or the electronic money server 2) via the terminal communication unit 27 or the like. Moreover, it functions as an amount change means for changing the amount stored in the electronic money storage unit 29 using the received amount change information.

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.

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 confirmation log data, and other programs. .
The data storage unit 57 stores a member store database storing member store information, a transaction database storing use log data with the electronic money card 6, and the like.

FIG. 7 is a diagram illustrating an example of a logical configuration of usage log data.
The usage log data includes “electronic money function unit ID”, “transaction amount”, “transaction date / time / minute / second”, “member store ID”, “transaction valid 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 settlement or charge and the amount of settlement or charge 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 “transaction valid flag”, whether or not the money amount changing process is successful in the electronic money card 6 is recorded as flag information. “Valid” is recorded as a flag when the electronic money card 6 is processed with the amount change information, and “invalid” is recorded when the processing with the amount change information is not performed.

When a special abnormal situation occurs such as when the user takes away the electronic money card 6 from the reader / writer unit 39 when reading the value balance after unsuccessful retry or the electronic money card 6 breaks down due to a lightning strike or the like. , Value balance may not be confirmed.
In such an exceptional case, an “exception” is recorded as a transaction valid flag, and the electronic money center handles it individually.

  In the usage log data, as other items, for example, “terminal ID” that is ID information of the electronic money terminal 8 that performed the processing, IC chip ID that is ID information unique to the IC chip, transaction of the electronic money terminal 8 A serial number such as “terminal transaction serial number” can also be recorded.

Next, settlement processing performed by the electronic money card 6 and the electronic money terminal 8 will be described using 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.
The charge process can also be performed in the same procedure.

First, the customer places the electronic money card 6 on the reader / writer unit 39, and the member in charge of the member store inputs the payment amount to the electronic money terminal 8.
When the electronic money card 6 is placed on the reader / writer unit 39, the electronic money terminal 8 detects this and starts communication with the electronic money card 6, and although not shown in the flowchart, the electronic money card 6 has an ID reference command. To request the electronic money card 6 to transmit the electronic money function unit ID.
The electronic money card 6 receives and executes the ID reference command, reads the electronic money function unit ID from the electronic money storage unit 29, and transmits it to the electronic money terminal 8.
The electronic money terminal 8 receives the electronic money function unit ID from the electronic money card 6 and stores it in the RAM 34 (FIG. 5) or the like.

  Next, the electronic money terminal 8 transmits a balance reference command to the electronic money card 6 and requests the electronic money card 6 for the current value balance of the electronic money card 6 (that is, the value balance before the amount change processing). (Step 5).

The electronic money card 6 receives and executes the balance reference command, reads the current value balance from the electronic money storage unit 29, and transmits it to the electronic money terminal 8 (step 10).
The electronic money terminal 8 receives the value balance from the electronic money card 6 and stores it in the RAM 34 (step 15).
Thus, the electronic money terminal 8 is provided with the 1st balance acquisition means which acquires the balance before transmitting money amount change information from a money terminal.
Next, the electronic money terminal 8 generates amount change information for reducing the value corresponding to the settlement amount and transmits it to the electronic money card 6 (step 20).
As described above, the electronic money terminal 8 includes an amount change information generation unit that acquires the amount related to the change and generates the amount change information, and an amount change information transmission unit that transmits the amount change information to the money terminal. ing.

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 payment amount and update it.
When the update of the value balance is successful, the electronic money card 6 sends a predetermined notification to the electronic money terminal 8 to give a response to the electronic money terminal 8 that the amount change processing is completed. If the amount change processing is completed, a predetermined notification is transmitted to the electronic money terminal 8 to respond (step 25).

After transmitting the money amount change information to the electronic money card 6, the electronic money terminal 8 waits for a response from the electronic money card 6 for a predetermined time.
When the electronic money terminal 8 receives a response from the electronic money card 6 within a predetermined time (that is, when a predetermined notification is received from the electronic money card 6), the electronic money terminal 8 determines that the amount change processing has been successful with the electronic money card 6. (Step 30; Y). Then, the electronic money terminal 8 generates usage log data by setting the transaction valid flag to “valid” (step 35) and stores it in the data storage unit 44.
As described above, the electronic money terminal 8 includes a notification receiving unit that receives notification from the money terminal that the amount has been changed based on the amount change information.

When there is no response from the electronic money card 6 within a predetermined time, the electronic money terminal 8 transmits the amount change information to the electronic money card 6 again and performs a retry.
If there is no response from the electronic money card 6 even after retrying, the electronic money terminal 8 recognizes whether or not the money amount change processing has been performed on the electronic money card 6 (step 30; N).
The retry can be configured to be performed a plurality of times, or can be configured not to perform the retry.

As described above, when the electronic money terminal 8 recognizes that it is unknown whether or not the money amount change process has been performed on the electronic money card 6, it transmits a balance reference command to the electronic money card 6, Request for notification of the value balance (step 40).
At this time, the electronic money terminal 8 can notify the person in charge of confirming the value balance by display or voice.
As described above, the electronic money terminal 8 includes the second balance acquisition means for acquiring the current balance from the money terminal when there is no response from the electronic money card 6 (when a predetermined notification is not received). Yes.
The electronic money card 6 receives and executes a balance reference command from the electronic money terminal 8, reads the value balance from the electronic money storage unit 29, and transmits it to the electronic money terminal 8 (step 45).

The electronic money terminal 8 receives the current value balance from the electronic money card 6 and compares it with the value balance before processing stored in step 15.
As a result of the comparison, if the current value balance is smaller than the value balance stored in step 15, the electronic money terminal 8 determines that the amount change processing by the reduction is successful in the electronic money card 6.
On the other hand, when the current value balance and the value balance stored in step 15 are the same, the electronic money terminal 8 determines that the amount change processing in the electronic money card 6 has been unsuccessful.
As described above, the electronic money terminal 8 has the balance acquired by the first balance acquisition unit (value balance before sending the amount change information), the balance acquired by the second balance acquisition unit (current value balance), And a determination means for determining whether or not the money amount change by the money amount change information has been performed at the money terminal based on the comparison result by the comparison means.

Next, the electronic money terminal 8 performs value balance confirmation processing, generates usage log data, and stores it in the data storage unit 44 (step 50).
The electronic money terminal 8 sets the transaction valid flag of the usage log data to “valid” when the amount change processing is successful, and to “invalid” when it is unsuccessful.
Further, for example, if the value balance cannot be confirmed because the user has taken away the electronic money card 6 or the like, “exception” is set.

As described above, the electronic money terminal 8 compares the value balance before sending the amount change information with the value balance after sending the amount change information to determine whether or not the amount change process has been performed on the electronic money card 6. Can be confirmed.
In the above example, if the amount change processing was unsuccessful, the usage log data with the transaction valid flag set to “invalid” was generated and the processing was terminated, but the amount change processing was unsuccessful. It can also be configured to retry further when it is confirmed.
In this way, when the electronic money terminal 8 determines that the amount change has not been performed, the amount change information transmission unit transmits the amount change information to the money terminal again (that is, retry). Can also be configured.

Further, not only the magnitude relationship between the current value balance and the stored value balance, but also the amount difference can be confirmed.
In this case, the electronic money terminal 8 checks whether or not the current value balance is equal to the value balance subtracted from the value balance stored in step 15, and if it is equal, the money amount change process has been successful. If it is not equal, it is recognized as unsuccessful.

Although the above example was the case of payment, the electronic money terminal 8 and the electronic money card 6 perform the same processing in the case of charging.
In the case of charging, when comparing the value balance before processing stored in step 15 and the current value balance, if the current value balance is greater than the value balance stored in step 15, The electronic money terminal 8 determines that the amount change process by the increase has been performed on the electronic money card 6, and if these are equal, it determines that the amount change process by the amount change information was unsuccessful.

FIG. 9 is a flowchart for explaining a procedure in which the electronic money terminal 8 transmits usage log data to the electronic money server 2.
The electronic money terminal 8 connects a communication line to the electronic money server 2 at a predetermined time about once a day. Then, the usage log data accumulated in the data storage unit 44 since the previous transmission is transmitted to the electronic money server 2 (step 55).
The electronic money server 2 receives the usage log data from the electronic money terminal 8 and stores it in the data storage unit 57 (step 60).
As described above, the electronic money server 2 accumulates the usage log data in the data storage unit 57 for a certain period (for example, one month), and then totalizes the total charge amount and the total settlement amount for each member store. (Step 75).

FIG. 10 is a flowchart for explaining a procedure for the electronic money server 2 to perform a counting process in step 75 of FIG.
The electronic money server 2 performs the following processing for each member store.
First, the electronic money server 2 reads the usage log data of the member store from the data storage unit 57 using the member store ID of the member store to be counted (step 95).

Then, the electronic money server 2 checks the transaction validity flag of the read usage log data (step 100).
When the transaction valid flag is “valid” (step 100; valid), the electronic money server 2 aggregates the usage log data as a fund settlement target (step 105).
When the transaction valid flag is “invalid” (step 100; invalid), the electronic money server 2 processes the usage log data as not being subject to fund settlement (step 110).

Further, when the transaction valid flag is “exception” (step 100; exception), the electronic money server 2 performs exception processing such as classifying the usage log data into an exception directory (step 115).
The usage log data classified in this directory is individually handled by, for example, a person in charge of the electronic money center.

As described above, after processing the usage log data, the electronic money server 2 confirms whether or not processing has been performed for all the usage log data of the member store (step 120).
If there is still unprocessed usage log data (step 120; N), the electronic money server 2 returns to step 95 to process the usage log data. On the other hand, when all the usage log data have been processed (step 120; Y), the electronic money server 2 ends the aggregation process of the member store.

The following effects can be obtained by the present embodiment described above.
(1) The electronic money terminal 8 compares the value balances of the electronic money card 6 and the mobile phone 7 before and after sending the amount change information, so that a response that the amount change information has been executed is a response to the electronic money card 6 and the mobile phone 7. Even if not, it can be confirmed whether or not the electronic money card 6 or the mobile phone 7 has executed the money amount change information.
(2) The electronic money terminal 8 confirms whether or not the money amount change information has been executed even if there is no response after the money amount change processing from the electronic money card 6 or the mobile phone 7 and the usage log data cannot be generated. Can be recorded in the data.
(3) The electronic money server 2 can check the transaction validity flag of the usage log data, and can make the amount of money change information executed even if there is no response as a target for fund settlement.

(Modification)
Next, a modification of the present embodiment will be described.
FIG. 11 is a diagram for explaining the configuration of the electronic money system 1 according to the present modification.
The electronic money system 1 according to the present embodiment includes a headquarter server 60 operated by the headquarters of each member store. The headquarter server 60 constitutes a POS system (Point Of Sales System) together with the POS unit 62 incorporated in the electronic money terminal 8, and collects information such as sales from each member store.

The electronic money terminal 8 includes a POS unit 62, an electronic money module 61, a reader / writer unit 39, and the like.
The POS unit 62 gives various instructions such as an amount change instruction, an ID reference instruction, and a balance reference instruction to the electronic money module 61, and the electronic money module 61 responds to these instructions with an amount change information and an ID reference command. Then, a balance reference command or the like is generated and transmitted to the electronic money card 6 via the reader / writer unit 39.

Then, the electronic money module 61 transmits to the POS unit 62 the response indicating whether or not the money amount change process has been successful, the electronic money function unit ID, the value balance, etc. returned from the electronic money card 6 in response to these commands. To do.
That is, the electronic money module 61 functions as an intermediary unit for processing performed by the POS unit 62 on the electronic money card 6.
In this way, by separating the POS unit 62 that issues an instruction and the electronic money module 61 that generates a command, security-related information such as a secret key can be sealed in the electronic money module 61, and the safety of the system can be increased. Can be increased.

The electronic money module 61 generates and stores usage log data and later-described confirmation log data for processing with the electronic money card 6 and transmits them to the electronic money server 2 at predetermined intervals.
The usage log data generated in this modified example is obtained by removing the item “transaction valid flag” from FIG. 7, and includes “electronic money function unit ID”, “transaction amount”, “transaction date / time / minute / second”, “member store”. ID "and other items.

Further, the electronic money module 61 generates confirmation log data that is required and transmits it to the electronic money server 2 when there is no response after sending the money amount change information to the electronic money card 6 and the retry fails.
The content of the confirmation log data that is required is obtained by setting a confirmation flag indicating that confirmation is required in addition to the same content as the usage log data according to the present modification.
In this way, the electronic money terminal 8 records, in the electronic money module 61, log data that records the amount of money related to the money amount change information and whether or not a notification indicating that the money amount has been changed has been received from the electronic money card 6. First log data transmission means for generating (utilization log data and confirmation log data required) and transmitting it to a predetermined server (in this case, the electronic money server 2) is provided.

On the other hand, if there is no response after the electronic money module 61 transmits the amount change information to the electronic money card 6 and the retry fails, the POS unit 62 transmits the amount change information before and after transmission as in the previous embodiment. The subsequent value balances are compared, and confirmation log data is generated and stored.
The contents of the confirmation log data are the same as the use log data shown in FIG. 7, and are “electronic money function unit ID”, “transaction amount”, “transaction date / time / minute / second”, “member store ID”, “transaction valid flag”. "And other items.
Since the communication line is connected to the headquarter server 60, the POS section 62 transmits confirmation log data to the headquarter server 60 every predetermined period.
As described above, the electronic money terminal 8 generates the confirmation log data in the POS unit 62 in correspondence with the confirmation log data required, and transmits the second log data to the predetermined server (here, the headquarter server 60). Means.
The POS unit 62 can also be configured to transmit confirmation log data directly to the electronic money server 2 as a predetermined server.
As described above, the predetermined server that is the transmission destination of the log data (use log data and confirmation log data that is required) and the predetermined server that is the transmission destination of the confirmation log data can be configured to be different servers. However, it can also be configured to be the same server.

  As described above, the electronic money module 61 generates the confirmation log data that is required, and the confirmation log data is generated by the POS unit 62. However, the electronic money module 61 does not generate the confirmation log data. This is because the POS unit 62 is an intermediary unit between the electronic money card 6 and the POS unit 62 determines whether or not the transaction is successful.

The headquarter server 60 collects the confirmation log data transmitted from the POS unit 62 of each member store into one data and transmits it to the electronic money server 2 every predetermined period.
In this way, by collecting the confirmation log data into one data, the load on the electronic money server 2 can be reduced.
In this way, the headquarter server 60 functions as an aggregation server that aggregates a plurality of confirmation log data into one log data.

Here, operations of the POS unit 62 and the electronic money module 61 will be described in more detail.
First, the POS unit 62 receives an input of a charge amount and a settlement amount from a person in charge.
Then, the POS unit 62 causes the electronic money module 61 to read the current value balance of the electronic money card 6.
The POS unit 62 stores the current value balance, that is, the value balance before sending the amount change processing information.

Thereafter, the POS unit 62 instructs the electronic money module 61 to transmit the amount change information.
When there is a response from the electronic money card 6 within a predetermined time, the POS unit 62 ends the process, and the electronic money module 61 generates usage log data.

When there is no response from the electronic money card 6 within a predetermined time, the POS unit 62 causes the electronic money module 61 to retry, and when the retry is successful, the POS unit 62 ends the processing, and the electronic money module 61 Generates usage log data.
If the retry is unsuccessful, the POS unit 62 instructs the electronic money module 61 to inquire about the value balance of the electronic money card 6.

In response to this command, the electronic money module 61 reads the value balance of the electronic money card 6 and transmits it to the POS unit 62 and generates confirmation log data that is required.
On the other hand, the POS unit 62 receives the current value balance from the electronic money module 61, and compares the value balance before sending the amount change information with the current value balance. Then, in the same manner as in the previous embodiment, it is confirmed whether or not the money amount change information has been executed in the electronic money card 6, and confirmation log data in which the result is recorded is generated.
The transaction valid flag of the confirmation log data is set to “valid” when the execution of the amount change information can be confirmed, and set to “invalid” when the execution of the amount change information can be confirmed, and the value balance can be confirmed. If not, it is set to “Exception”.

The usage log data and the confirmation log data required as described above are transmitted from the electronic money module 61 to the electronic money server 2, and the confirmation log data is transmitted to the electronic money server 2 via the headquarter server 60.
The confirmation log data may be directly transmitted from the POS unit 62 to the electronic money server 2.

FIG. 12 is a flowchart for explaining a procedure in which the electronic money terminal 8 transmits various log data to the electronic money server 2.
First, the electronic money terminal 8 (electronic money module 61) connects to the electronic money server 2 and transmits usage log data and confirmation log data requiring confirmation to the electronic money server 2 (step 130).
The electronic money server 2 receives the usage log data and the confirmation log data required from the electronic money terminal 8 and stores them in the data storage unit 57 (step 135). As described above, the electronic money server 2 includes the first log data receiving unit.

Next, the electronic money terminal 8 (POS unit 62) transmits the confirmation log data to the headquarter server 60, and the headquarter server 60 transmits it to the electronic money server 2 (step 140).
The electronic money server 2 receives the confirmation log data from the electronic money terminal 8 via the headquarter server 60 and stores it in the data storage unit 57 (step 145). As described above, the electronic money server 2 includes the second log data receiving unit.
Then, the electronic money server 2 performs a totaling process using the use log data, the confirmation log data required, and the confirmation log data stored in the data storage unit 57 (step 150).
Note that any of the usage log data, the confirmation log data requiring confirmation, and the confirmation log data may be transmitted to the electronic money server 2 first.

FIG. 13 is a flowchart for explaining a procedure for the electronic money server 2 to perform aggregation processing.
The electronic money server 2 performs the following processing for each member store.
First, the electronic money server 2 reads the use log data of the member store to be processed using the member store ID from the data storage unit 57 (step 180), and totalizes it as a fund settlement target (step 185). .
Then, the electronic money server 2 checks whether or not all usage log data for the member store has been processed. If there is usage log data that has not been processed yet (step 190; N), the electronic money server 2 proceeds to step 180. Go back and count the usage log data.

When all usage log data has been processed (step 190; Y), the electronic money server 2 reads the log data required for confirmation of the member store (step 195).
Next, the electronic money server 2 searches the data storage unit 57 for confirmation log data corresponding to the read necessary log data (step 200).
This search can be performed using, for example, the electronic money function unit ID and the transaction date and time as the key. As described above, the electronic money server 2 includes a search unit.

The electronic money server 2 confirms the transaction valid flag of the retrieved confirmation log data, and if it is “valid” (step 205; valid), the confirmation log data required is counted as a fund settlement target (step 210), If it is “invalid” (step 205; invalid), the necessary confirmation log data is processed out of the fund settlement target (step 215).
If the transaction valid flag is “exception” (step 205; exception), the electronic money server 2 performs exception processing such as classifying it into an exception directory (step 220), and is responsible for the electronic money center. Deal with them individually.
As described above, the electronic money server 2 includes a confirmation unit that confirms the confirmation log data requiring confirmation using the confirmation log data.

  Next, the electronic money server 2 confirms whether or not all the necessary confirmation log data regarding the member store has been processed. If there is necessary confirmation log data that has not yet been processed (step 225; N), the step Returning to 195, the processing is continued, and when all the necessary confirmation log data has been processed (step 225; Y), the aggregation processing is terminated.

As described above, by providing the POS system with the confirmation log data generation function, even when the confirmation log data is generated in the electronic money module 61, it is determined whether or not the transaction based on the confirmation log data is valid. be able to.
In this embodiment, the transaction validity is confirmed by the POS unit 62. However, the electronic money server 2 may be configured to confirm this.
In this case, the electronic money server 2 receives the electronic money function unit ID, the transaction date / time minute / second, and the value balance before and after sending the money amount change information from the POS unit 62, and the electronic money function unit ID and the transaction date / time. Corresponding to the log data required for confirmation in minutes and seconds, it is confirmed whether or not the money amount change information has been executed in the electronic money card 6 by comparing the value balance before and after sending the money amount change information.
