Description

The present invention relates to a data change device, a data change method, a data change program, a reader / writer, a data transfer method, and a data transfer program , for example, a terminal that communicates with an electronic money card.

In recent years, an electronic money system has been constructed, and settlement with electronic money is widely performed.
In the electronic money system, an electronic money card owned by a user and a store terminal provided in the store are used.
The electronic money card stores an amount of money information called “value” and has an IC chip having a function of increasing / decreasing this amount using amount change information (addition / subtraction command). It has a function to send money amount change information.

When the user pays for the product, the change amount information for reducing the value for the price is transmitted from the store terminal to the electronic money card, and the amount of the value stored in the electronic money card is reduced.
In addition, the user can pay the store, send the amount change information for increasing the value of the price to the electronic money card, and increase the amount of value stored in the electronic money card. This process is called charging.

The store terminal records and accumulates the contents of such processing as usage log data, and transmits it to the electronic money server all at once later.
The electronic money server aggregates usage log data transmitted from the store terminals of each store, and performs fund settlement between stores.
In this way, in the electronic money system, the correspondence between the value and the currency is taken, and the value can be used as a substitute for the currency.
As described above, as a technique for making a payment using the value stored in the IC chip, for example, there is the following service providing method.
JP 2000-250994 A

Here, the configuration of the store terminal is shown in FIG.
As shown in the figure, the store terminal 8 is configured by using a host terminal 2, a command module 3, and a reader / writer 4.
The reader / writer 4 is provided with an installation surface for the electronic money card 6. When the electronic money card 6 is placed or held over the installation surface, the IC chip of the reader / writer 4 and the electronic money card 6 is wirelessly connected. Connected by.

The host terminal 2 issues an amount change request to the command module 3, for example, “Subtract 100 yen” or “Add 2000 yen”.
In response to the request from the upper terminal 2, the command module 3 generates amount change information and transmits it to the reader / writer 4.

The reader / writer 4 receives the amount change information from the command module 3 and transmits it to the IC chip of the electronic money card 6 wirelessly.
The electronic money card 6 executes the amount change information transmitted from the reader / writer 4 to increase or decrease the amount of value stored in itself.

Conventionally, the above processing is performed according to the procedure shown in the flowchart of FIG. The following operations of the electronic money card are performed by an IC chip built in the electronic money card.
First, the shop terminal 8 monitors the installation of the electronic money card 6 in the reader / writer 4 and performs a detection process when the electronic money card is installed (step 5).
Thereafter, the command module 3 repeats the following card checking operation in steps 10 to 30 every A [ms] (A is about 50 to 200), and checks the connection of the electronic money card 6 every A [ms]. .

First, the command module 3 sends a response request (Request Response) to the reader / writer 4 (step 10). When the reader / writer 4 receives a response request from the command module 3, the reader / writer 4 acknowledges the command module 3 (Step 15) and makes a response request to the electronic money card 6 (Step 20).
The command module 3 confirms that the reader / writer 4 has received the response request.

When the electronic money card 6 receives a response request from the reader / writer 4, the electronic money card 6 responds (step 25), and when the reader / writer 4 receives a response from the electronic money card 6, the electronic money card 6 responds to the command module 3 (step 30). ).
The command module 3 can recognize that the electronic money card 6 is wirelessly connected to the reader / writer 4 by receiving a response from the reader / writer 4.
The following steps 35 to 55 are the same.
The store terminal 8 confirms the connection of the electronic money card 6 every A [ms] as described above, and assumes that the electronic money card 6 is connected during that time.

Then, when the upper terminal 2 makes a money amount change request to the command module 3 while the connection of the electronic money card 6 is confirmed (step 60), the command module 3 acknowledges the upper terminal 2 (step 65). .
Then, the command module 3 generates amount change information for performing the requested addition / subtraction, and transmits it to the reader / writer 4 (step 70).
When the reader / writer 4 receives the money amount change information from the command module 3, the reader / writer 4 acknowledges the command module 3 (step 75) and transmits the money amount change information to the electronic money card 6 (step 80).

When the electronic money card 6 receives the amount change information from the reader / writer 4, the electronic money card 6 executes this to increase or decrease the amount of value stored by itself, and when the amount change processing is completed, the amount change processing is completed in the reader / writer 4. A response to this effect is made (step 85).
When receiving a response from the electronic money card 6, the reader / writer 4 sends a response to the command module 3 to the same extent (step 90).

The command module 3 recognizes that the amount change processing has been performed by the response from the reader / writer 4, and responds to that effect to the upper terminal 2 (step 95).
Upon receiving the response from the command module 3, the upper terminal 2 acknowledges the command module 3 (step 100).
As described above, the upper terminal 2 recognizes that the money amount change process has been successful in the electronic money card 6 by the response from the command module 3.
In the above example, the consent operation is performed in step 100 or the like. However, this consent operation may or may not be performed.

Since the command module 3 confirms the connection of the electronic money card 6 at a time interval of A [ms], the electronic money is within A [ms] after the command module 3 confirms the connection to the electronic money card 6. When the card 6 becomes in an unstable communication state due to failure or removal (for example, the timing indicated by “card removal” in FIG. 9), the electronic money card is transmitted although the reader / writer 4 sends the amount change information. No response is received from 6.
In such a state where there is no response, the store terminal 8 is in an unconfirmed state in which it cannot be confirmed whether or not the money amount change information has been executed by the electronic money card 6.

  That is, when the electronic money card 6 is removed between step 50 and step 80 in FIG. 9, the amount change information is not delivered to the electronic money card 6, and therefore the amount change processing is not performed on the electronic money card 6. On the other hand, when the electronic money card 6 is removed between step 80 and step 85, the money amount change information is delivered to the electronic money card 6, so that the electronic money card 6 performs addition / subtraction processing.

More specifically, when the command module 3 receives a request for changing the amount from the upper terminal 2 and starts the amount change information transmission process, the card confirmation process is not performed during that time.
In addition, before the money amount change information is transmitted to the electronic money card 6 in the money amount change information transmission process, an overhead pre-processing is included, and when the time is B [ms], it is about A + B [ms]. There is a time when the card is not verified.

Thus, depending on the removal timing of the electronic money card 6, there are cases where the money amount changing process is performed or not, and the store terminal 8 recognizes whether or not the money amount changing process is performed on the electronic money card 6. I can't.
Since the electronic money card 6 uses a non-contact type IC chip, such an unconfirmed state is more likely to occur than when a contact type IC card is used, and it is necessary to take some measures.

FIG. 4 is a diagram illustrating an example of a hardware configuration of the command module 3.
The command module 3 has a function that requires confidentiality, such as generating money amount change information or encrypting communication with the electronic money card 6, and is thus made into a black box and incorporated in the store terminal 8. .

The store terminal 8 is configured by connecting a CPU 51, a ROM 52, a RAM 54, a communication control unit 53, a host terminal connection unit 58, a reader / writer connection unit 59, and the like through a bus line.
The CPU 51 performs information processing according to a predetermined program, and controls the store terminal 8 as a whole.
In the present embodiment, the CPU 51 transmits money amount change information to the electronic money card 6 while confirming the connection between the electronic money card 6 and the reader / writer 4, and causes the electronic money card 6 to perform money amount change processing or use it. Log data is generated and stored in the storage unit 55, or usage log data stored in the storage unit 55 is transmitted to the electronic money server.

A procedure for the money amount changing process between the upper terminal 2 and the electronic money card 6 configured as described above will be described with reference to the flowchart of FIG .
Note that the same steps as those in the conventional example of FIG. 9 are given the same step numbers, and in order to avoid complication of the drawings in the flowchart, a notification of consent (step 15 in FIG. 9) and a response (steps in FIG. 9). 25) will be omitted.

First, a store accountant operates the host terminal 2 to start detection processing of the electronic money card 6.
Then, the store terminal 8 prompts the user to place the electronic money card 6 by, for example, blinking the electronic money card installation surface of the reader / writer 4.
The command module 3 makes a response request to the electronic money card 6 at a predetermined time interval after the detection processing of the electronic money card 6 starts, and the electronic money card 6 responds to this when installed in the reader / writer 4. .
As a result, the command module 3 detects the connection of the electronic money card 6 and notifies the host terminal 2 that the electronic money card 6 has been installed. In this way, card detection processing of the electronic money card 6 is performed (step 5).

When the electronic money card 6 is subjected to card detection processing, the command module 3 makes a response request to the reader / writer 4 to confirm whether the electronic money card 6 is still installed in the reader / writer 4 (step 10). ).
When the reader / writer 4 receives a response request from the command module 3, the reader / writer 4 acknowledges the command module 3 and makes a response request to the electronic money card 6 (step 20).

  The electronic money card 6 responds to a response request from the reader / writer 4, and the reader / writer 4 responds to the command module 3 when a response is received from the electronic money card 6 (step 30).

As in the conventional example, the command module 3 and the reader / writer 4 repeat the above card checking operation every A [ms] to confirm that the state in which the electronic money card 6 is installed in the reader / writer 4 is maintained. Confirm every [ms] (step 35 to step 55, etc.).
If the connection of the electronic money card 6 cannot be confirmed by this card confirmation operation, the command module 3 continues the card confirmation operation, while the host terminal 2 detects that the command module 3 detects the electronic money card 6. Wait for a predetermined time.
Then, when the predetermined time has elapsed, the upper terminal 2 commands the command module 3 to stop the card check operation, and the command module 3 stops the card check operation.
Even before the predetermined time elapses, the person in charge can manually interrupt and allow the command module 3 to end the card checking operation.
Note that the command module 3 can notify the host terminal 2 that the connection of the electronic money card 6 has not been confirmed, and the host terminal 2 can thereby be configured to stop processing.

On the other hand, if the existence of the electronic money card 6 is confirmed at intervals of A [ms], the upper terminal 2 makes a money amount change request to the command module 3 (step 60).
This amount change request includes, for example, “settlement of 300 yen”, the distinction between settlement and charge, and the amount to be increased or decreased.

When the command module 3 receives an amount change request from the upper terminal 2 (that is, when an amount change request from the upper terminal 2 is detected), the command module 3 requests a response to the reader / writer 4 regardless of the interval of A [ms]. (Step 205).
Upon receiving this, the reader / writer 4 acknowledges the command module 3 and requests the electronic money card 6 for a response (step 210).
When there is a response from the electronic money card 6 to this response request, the reader / writer 4 responds to the command module 3. This response process is the same as steps 10 to 30.

As described above, the command module 3 includes a confirmation unit that detects that the request reception unit (a function of receiving a money amount change request from the host terminal 2) has received a money amount change request and performs a card check operation.
In addition to the function of performing the card confirmation operation at the A [ms] interval (first card confirmation function), the command module 3 uses this as a trigger to confirm the card when there is a money amount change request. A function for performing an operation (second card confirmation function) is provided.

When the connection of the electronic money card 6 cannot be confirmed by this card confirmation operation, the command module 3 notifies the upper terminal 2 to that effect, and the upper terminal 2 stops the processing.
On the other hand, when the connection of the electronic money card 6 is confirmed, the command module 3 starts the money amount change information transmission process.

The command module 3 performs various pre-processing in the amount change information transmission process, and then transmits the amount change information to the reader / writer 4 (step 70).
The reader / writer 4 receives the money amount change information from the command module 3 and accepts it to the command module 3, and transmits the money amount change information to the electronic money card 6 (step 80).

The electronic money card 6 receives the amount change information from the reader / writer 4 and executes it, and after changing the value, responds to the reader / writer 4 (step 85).
Upon receiving the response from the electronic money card 6, the reader / writer 4 responds to the command module 3 (step 90), and the command module 3 receives this response and responds to the upper terminal 2 (step 95). Then, the upper terminal 2 receives this response and gives consent to the command module 3.

  As described above, in the present embodiment, after the command module 3 receives the money amount change request from the upper terminal 2 in step 60, before the command module 3 starts the money amount change information transmission process, the second Since the card confirmation function confirms the connection of the electronic money card 6 separately from the card confirmation every A [ms], the time from when the card is confirmed until the money amount change information is delivered to the electronic money card 6 This can be shortened compared with the case of only the card confirmation operation for every [ms], and the probability of occurrence of unconfirmed processing can be reduced.

According to the embodiment described above, the following effects can be obtained.
(1) In the conventional example, the money amount change request of the upper terminal 2 and the card check operation of the command module 3 are independent and not synchronized. In this embodiment, the money amount change request of the upper terminal 2 is triggered. Since the command module 3 performs the card confirmation operation, the period during which the unconfirmed process may occur can be made shorter than in the conventional example.
(2) For this reason, the probability of occurrence of unconfirmed processing can be reduced, and the operation of the electronic money system can be further stabilized.
(3) This can be dealt with by newly rewriting the program of the command module 3, and it is not necessary to modify the electronic money card 6 that is widely distributed in general. Since the electronic money business operator grasps the location and operation status of the command module 3, the program can be easily updated.

(Modification 1)
Next, a first modification of the present embodiment will be described using the flowchart of FIG.
In this modification, in the amount change transmission process, the card confirmation process is performed immediately before the command module 3 transmits the amount change information to the reader / writer 4.
The command module 3 performs the card confirmation process immediately before sending the amount change information, thereby further shortening the time until the card confirmation process and the electronic money card 6 receive the amount change information.

Steps 10 to 60 are the same as in FIG.
When the command module 3 receives an amount change request from the upper terminal 2 in step 60, the command module 3 starts an amount change information transmission process.
The money amount change transmission process is composed of a series of processes of pre-processing before sending money amount change information, sending money amount change information, and post-processing after that, as described in FIG. When the preprocessing is completed, the command module 3 makes a response request to the reader / writer 4 (step 305).

When the reader / writer 4 receives a response request from the command module 3, it accepts the command module 3 and then issues a response request to the electronic money card 6 (step 310).
When the electronic money card 6 receives this response request and responds to the reader / writer 4, the reader / writer 4 responds to the command module 3 (step 315).

If there is no response from the reader / writer 4, the command module 3 reports to the upper terminal 2 that the electronic money card 6 is not connected, and performs transmission stop processing for the amount change information.
On the other hand, when there is a response from the reader / writer 4, the command module 3 generates amount change information and transmits it to the reader / writer 4 (step 70).
The subsequent steps are the same as in FIG.

Next, money amount change information transmission processing performed by the command module 3 will be described using the flowchart of FIG.
The same processes as those in FIG. 6 are denoted by the same step numbers.
First, the command module 3 confirms whether or not the parameters of the upper command included in the money amount change request received from the upper terminal 2 are normal (step 505).

For example, when the upper limit of the value of the electronic money card 6 is 50,000 yen and the charge of 100,000 yen is specified by the parameter, the command module 3 recognizes that the parameter is abnormal.
Further, when the current date and time attached as a parameter included in the money amount change request is clearly wrong, the command module 3 recognizes that the parameter is abnormal.

If it is determined that the parameter is abnormal (step 505; abnormal), the command module 3 performs transmission stop processing (step 540), and stops the amount change information transmission processing.
On the other hand, when it is determined that the parameters are normal (step 505; normal), the command module 3 further checks the data of the electronic money card 6 (step 510).

This process reads the electronic money function unit ID, value balance, log data, and the like from the electronic money card 6 (this reading may be performed at this time or may be performed at the stage of step 5 in FIG. 6). , It may be performed at other timing), and it is performed by confirming that these are appropriate. For example, when the value balance is less than the payment amount, it is determined to be abnormal.
When it is determined that the data of the electronic money card 6 is abnormal (step 510; abnormal), the command module 3 performs a transmission stop process (step 540).

  On the other hand, when it is determined that the data of the electronic money card 6 is normal (step 510; normal), the command module 3 creates, for example, money amount change information and usage log data (for temporary settlement, the electronic money card Data creation processing such as creation of the usage log data after the amount change processing is completed in step 6 is performed (step 515).

Steps 505 to 515 described above are preprocessing that causes overhead.
After completing these preprocessing, the command module 3 makes a response request to the reader / writer 4 (step 305).
When the command module 3 cannot normally receive a response from the reader / writer 4 (step 525; N), the command module 3 performs transmission stop processing (step 540).

On the other hand, when the response is normally received from the reader / writer 4 (step 525; Y), the command module 3 transmits the amount change information to the reader / writer 4 (step 70).
Then, after receiving a response from the reader / writer 4 that the electronic money card 6 has executed the money amount change information, the command module 3 performs post-transmission processing such as determining usage log data (step 535).

  As described above, the money amount change information transmission process includes the pre-process before sending the money amount change information, the transmission of the money amount change information, and the post-process after the transmission. The command module 3 includes confirmation means for performing connection confirmation processing of the electronic money card 6 immediately before transmission of the amount change information.

  In Modification 1, since the card confirmation process is incorporated in the money amount change information transmission process and the card module performs the card confirmation process immediately before the money amount change information is transmitted, the money amount change information from the electronic money card 6 to the card confirmation process. Can be further shortened. As a result, the probability of occurrence of unconfirmed processing can be reduced as compared with the embodiment described above.

(Modification 2)
Next, Modification 2 will be described using the flowchart of FIG.
In the second modification, the reader / writer 4 performs a card confirmation process immediately before the reader / writer 4 transmits the amount change information to the electronic money card 6.
Steps 5 to 70 are the same as those in the embodiment described with reference to FIG.
Upon receiving the money amount change information from the command module 3, the reader / writer 4 acknowledges the command module 3 and makes a response request to the electronic money card 6 (step 405).
The electronic money card 6 responds to a response request from the reader / writer 4 (step 410).

When there is no response, the reader / writer 4 notifies the command module 3 to that effect, and the command module 3 performs a transmission stop process.
When receiving a response from the electronic money card 6, the reader / writer 4 transmits the amount change information to the electronic money card 6 (step 80).
The following is the same as FIG.

  As described above, the reader / writer included in the electronic money terminal 8 receives the money amount change information transmitted by the connection means for connecting to the money terminal (IC chip of the electronic money card 6) by wireless communication and the transmission means of the command module 3. Receiving means, confirming means for confirming that the money terminal is connected by wireless communication before transmitting the received money amount change information to the money terminal, and receiving the received information after performing the confirmation. Transmitting means for transmitting money amount change information to the money terminal.

  In the second modification, since the reader / writer 4 performs the card confirmation process before the reader / writer 4 transmits the money amount change information to the electronic money card 6, the time until the money amount change information is transmitted after the card confirmation process is performed. Can be further shortened, and the probability of occurrence of unconfirmed processing can be further reduced.
