And a collision detection circuit 18 for detecting a collision of data such as response signals transmitted from the plurality of IC cards when the plurality of IC cards are electromagnetically coupled.
[0008]
FIG. 2 is a block diagram showing the configuration of the above-described IC card 2. The IC card 2 includes an IC chip 21 including a CPU 22, a ROM 23, and an electrically writable / erasable memory 24, a wireless circuit 25, It comprises the above-mentioned antenna AT2.
[0009]
Now, in the electronic money charge system configured as described above, when the IC card 2 is placed on the terminal device 1, the antenna AT2 of the IC card 2 and the antenna AT2 of the terminal device 1 are electromagnetically coupled, Power is supplied from the terminal device 1 to the IC card 2. When power is supplied, the CPU 22 of the IC card 2 transmits a response signal to the terminal device 1 via the wireless circuit 25 and the antenna AT2.
[0010]
When receiving the response signal via the antenna AT1, the radio circuit 19 and the decoding circuit 17 in the gate circuit 15, the CPU 11 of the terminal device 1 executes the authentication algorithm for transferring the value information stored in the SAM 14, Then, the predetermined amount of value information is transmitted to the IC card 2 side and stored in the memory 24 of the IC card 2. In this manner, the IC card 2 is charged with the value information.
In this way, shopping or the like is performed using the IC card 2 charged with the value information by the terminal device 1, and when the remaining amount of the IC card 2 is exhausted, the IC card 2 is charged with the value information again.
[0011]
FIG. 3 is a block diagram showing the configuration of the electronic money charge system according to the present invention, and shows an example of a bus fare payment system using the IC card 2. In FIG. 3, terminal devices 1A and 1B for charging the IC card 2 with the value information are installed at the office of the bus company, and each of the terminal devices 1A and 1B stores the value information in the IC card 2A based on the authentication algorithm of the SAM 14. Charge. The IC card 2A charged with the value information is supplied to the bus user in exchange for cash. Further, a terminal device 1C is installed at a bus company headquarters, which is a location where bus drivers gather, and the terminal device 1C charges value information to the IC card 2B based on an authentication algorithm of the SAM 14. The IC card 2B charged with the value information is supplied to a bus driver. Each of the terminal devices 1A to 1C is connected to a center 3 installed in the head office, and the value information charged to the IC card from each of the terminal devices 1A to 1C is centrally managed by the center 3.
[0012]
By the way, the memory 24 of the IC card 2 to which the value information is charged is divided into two areas 24A and 24B. Here, in the IC card 2A possessed by the bus user, the area information 24A of the memory 24 is charged with the value information from the terminal device 1A or the terminal device 1B. Further, in the IC card 2B possessed by the driver, the value information is charged from the terminal device 1C to the area 24B of the memory 24.
[0013]
Prior to the operation of the bus, the bus driver places his / her IC card 2B on the terminal device 1C and charges the value information from the terminal device 1C to the area 24B of the memory 24 of the own IC card 2B as described above. I do. The value information charged to the IC card 2B is, for example, several tens of times (for example, 30,000 yen) the limit (for example, 1,000 yen) of the value information to be charged to the IC card 2A possessed by the user.
Here, a terminal device 1D as shown in FIG. 4 for deducting a bus fee from the user's IC card 2A is installed in the operated bus. This terminal device 1D is configured similarly to the terminal device 1 of FIG. 1 for charging value information to the IC card 2A, and the user places his / her own IC card 2A on the terminal device 1D when the user gets off the bus. Then, based on the authentication algorithm of the SAM 14, the terminal device 1D withdraws the amount corresponding to the bus fare from the value information in the area 24A of the memory 24 of the user's IC card 2A as shown in FIG.
[0014]
If there is no value information on the user's IC card 2A, the driver places his / her own IC card 2B on the user's IC card 2A placed on the terminal device 1D. . Then, the respective antennas AT2 of the IC cards 2A and 2B and the antenna AT1 of the terminal device 1D are electromagnetically coupled, and power is supplied from the terminal device 1D to the respective IC cards 2A and 2B, so that the respective IC cards 2A and 2B. , The response signals indicating the unique card numbers are transmitted at the same time. Therefore, the transmission data of the IC cards 2A and 2B collide, and the collision of the data is detected by the collision detection circuit 18 of the terminal device 1D and transmitted to the CPU 11.
[0015]
In this case, the CPU 11 of the terminal device 1D recognizes that a plurality of IC cards are wirelessly connected to the terminal device 1D, and individually identifies the card numbers of the IC cards based on the collision data detected by the collision detection circuit 18. The designated IC card 2 is returned with information indicating whether or not the value information is charged in the area 24B of the memory 24 of the designated IC card 2. When the IC card 2 is identified from the return information as the driver's IC card 2B in which the value information is charged in the area 24B, the CPU 11 of the terminal device 1D determines the memory of the IC card 2B based on the authentication algorithm of the SAM 14. The value information charged in the 24 area 24B is reduced by a predetermined amount. At this time, the CPU 11 of the terminal device 1D designates the card number of the user's IC card 2A and similarly stores the value information for the predetermined amount in the area 24A of the memory 24 of the IC card 2A based on the authentication algorithm of the SAM 14. Charge.
[0016]
In this way, the value information is transferred from the driver-specific IC card 2B to the user's IC card 2A, and the user can pay the bus fare using the IC card 2A thereafter. When the value information is transferred from the driver-specific IC card 2B to the user's IC card 2A, the user pays the predetermined amount for the transferred value information.
[0017]
As described above, when the terminal device 1D having the same configuration as the terminal devices 1A and 1B for charging the IC card 2 with the value information is installed in the bus as a withdrawal machine, and the remaining amount of the bus user's IC card 2A is insufficient. By superposing the IC card 2A and the driver's IC card 2B on the terminal device 1D, the value information is transferred from the driver's IC card 2B to the bus user's IC card 2A. It was made. As a result, the bus user does not have to go to the bus office and charge the value information using the terminal device 1A or 1B every time the balance is exhausted on his or her IC card 2A, thereby improving the convenience of the bus user. improves.
Here, it is conceivable that a bus acquaintance has a driver's acquaintance and a driver who charges the IC card 2A owned by the acquaintance with value information free of charge. When transferring the value information from the hand-only IC card 2B to the user's IC card 2A, the transferred value information is subtracted from the IC card 2B. With this configuration, it is possible to prevent the driver from being improperly charged.
When transferring the value information of the driver's IC card 2B to the user's IC card 2A, the terminal device 1D does not subtract the value information corresponding to the transferred amount from the value information of the driver's IC card 2B. You can also.
[0018]
In the above-described embodiment, the example in which the IC card 2 is used to pay the bus fare is described. However, the terminal device 1D is installed in the store, and the value is stored in the area 24B of the memory 24 for the store clerk. If the user is shopping at a store by supplying the IC card 2B charged with the information and there is no value information in the user's IC card 2A at the time of payment, the clerk uses the terminal device 1D. Value information can also be transferred from the user IC card 2B to the user IC card 2A.
[0019]
That is, when there is no remaining amount in the user's IC card 2A, the IC card 2A and the clerk's IC card 2B are placed on the terminal device 1D. Then, the terminal device 1D similarly transfers the value information of the area 24B in the memory 24 of the IC card 2B dedicated to the clerk to the area 24A in the memory 24 of the user's IC card 2A. As a result, the user can continue using the IC card 2A thereafter. Therefore, in this case, the user does not need to go to a specific management place and charge the value information with the charging machine installed at the place, and the convenience for the user is improved. When the value information is transferred from the clerk's IC card 2B to the own IC card 2A by the terminal device 1D, the user pays the amount of the transferred value information to the clerk.
[0020]
【The invention's effect】
As described above, according to the present invention, when a wireless connection with a plurality of IC cards is detected, the terminal device transmits value information charged in a predetermined charge area of the first IC card. Since the transfer to the charge area of the second IC card is made, for example, when the user of the bus runs out of balance in his or her own IC card, his / her IC card is placed on the terminal installed in the bus. If placed together with the first IC card for the driver, the value information can be transferred from the first IC card, so that it is not necessary to go to the bus office every time and charge the value information by the charging machine in the office, The convenience for bus users can be improved.
In this case, the area of the IC card in which the value information is charged is divided into first and second areas, and the value information of the first area of the first IC card is stored in the second area of the second IC card. Since the transfer is performed, the terminal device can transfer the value information by accurately identifying the IC card to which the value information is to be transferred and the IC card to which the value information is to be transferred.
Further, in an electronic money charging system comprising an IC card, a first terminal device for charging value information to a wirelessly connected IC card, and a second terminal device for charging value information to a wirelessly connected IC card. When the second terminal device detects a wireless connection with a plurality of IC cards, the value information charged in the predetermined charge area of the first IC card is charged to the second non-contact IC card. Since the terminal is moved to the area, for example, the first IC card dedicated to the bus driver is mounted together with the second IC card of the user on the second terminal device installed as a fare reduction machine in the bus. If the value is transferred from the first IC card to the second IC card, and the value information is lost on the IC card, the bus user can operate the bus. There is no need to charge the value information by the charge machine of the business office and went to the place, as well as the convenience of the bus user is improved. Also, if a second terminal device is installed in the store as a charge reduction machine, and a first IC card dedicated to a store clerk is placed on the second terminal device together with the user's second IC card, Since the value transfer is similarly performed from the first IC card to the second IC card, the user needs to charge the IC card using a charging machine installed at a specific management place when the remaining balance is exhausted. And the convenience of the user is similarly improved.
In this case, the charge area of the IC card is divided into a first area and a second area, and the second terminal device transmits the value information of the first area of the first non-contact IC card to the second non-contact IC card. Is transferred to the second area, the second terminal device can also appropriately identify the IC card to which the value information is to be transferred and the IC card to which the value information is to be transferred, and transfer the value information.
Further, when transferring the value information of the first IC card to the second IC card, the value information of the first card is debited, so that unauthorized charging by the bus driver can be prevented.
