BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a non-contact storage medium compatible device, and more particularly to prevention of erroneous transaction with another non-contact storage medium.

[0002]

2. Description of the Related Art In an automatic ticket vending machine, a prepaid card may be used for purchase. A magnetic card is generally used as the prepaid card. For example, when purchasing a ticket, the user first inserts the prepaid card into the card insertion slot. Then, the automatic ticket vending machine takes in the prepaid card by the transport mechanism and transfers it to the internal data reading section. Here, a predetermined magnetic data reading process or the like is performed, a designated ticket is issued, and at the same time, the data of the prepaid card is rewritten to perform a reduction process. Then, the magnetic card is returned again using the transport mechanism.

However, in such an automatic ticket vending machine, the user needs to insert the prepaid card into the insertion slot each time, which makes the purchase operation troublesome. In addition, the prepaid card may be clogged internally due to, for example, a failure of the transport mechanism of the automatic ticket vending machine.

Therefore, in recent years, automatic ticket vending machines and the like compatible with non-contact cards have been proposed. This is, for example, when a non-contact card type prepaid card is placed in the communication area formed around the automatic ticket vending machine, the automatic ticket vending machine and the prepaid card communicate with each other and perform predetermined processing. Is.

That is, the user does not need to insert the prepaid card into the automatic ticket vending machine, and can purchase a ticket by simply approaching the automatic ticket vending machine with the prepaid card stored in a bag or the like. Becomes The balance rewriting process of the prepaid card is also performed in a contactless communication state. Further, in such an automatic ticket vending machine corresponding to a non-contact card, there is no need to carry out the operation of transporting the inserted card, and there is an advantage that clogging of the prepaid card can be avoided.

Incidentally, such a device compatible with a contactless card is also applied to ATMs and automatic ticket gates in banks.

[0007]

The conventional non-contact card compatible device has the following problems. When the contactless card is inserted into the communication area of the automatic ticket vending machine or the like, the predetermined communication is started only by this and the ticket issuing operation is performed. Therefore, for example, if another user intrudes into the communication area with a non-contact card type prepaid card, there is a problem that an interference situation occurs with the prepaid card owned by the other person and an erroneous transaction is performed. is there. If a wrong transaction is made,
The remaining amount of money is reduced from the prepaid card of another person.

The problem of erroneous transaction due to such interference also occurs in ATMs and automatic ticket gates for contactless cards. For example, in dealing with ATMs, there is a risk of interference between a plurality of cards owned by the user as well as interference by another person's card. That is, communication is performed with a card different from the card intended by the user, and transaction processing is performed for another account.

Therefore, an object of the present invention is to provide a non-contact storage medium compatible device capable of preventing erroneous transactions due to interference with other non-contact cards.

[0010]

In a non-contact storage medium compatible device according to the present invention, a receiving section and a receiving section which receive communication data transmitted from a non-contact storage medium as a communication target in a communicable area. It is characterized in that it is provided with an identification code discriminating means for discriminating an identification code included in the communication data and a display section for displaying the identification code discriminated by the identification code discriminating means.

[0011]

In the non-contact storage medium compatible device according to the present invention, the identification code determining means determines the identification code included in the communication data. Then, this identification code is displayed on the display unit. Therefore, it is possible to clearly understand the non-contact storage medium which is the current communication target. That is, when another non-contact storage medium enters the communicable area to cause an interference state, the interference state can be surely recognized.

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a non-contact storage medium compatible device according to the present invention will be described by taking a ticket vending machine as an example. First, FIG. 1 shows the appearance of this automatic ticket vending machine. A ticket is discharged from the issuing port 70 according to the selection and pressing of the purchase button 71. Further, the automatic ticket vending machine is provided with an antenna 4, and communication with a prepaid card which is a non-contact storage medium is performed through the antenna 4. A predetermined display is displayed on the display unit 2 under display control.

FIG. 2 shows a block diagram of the hardware of the automatic ticket vending machine. Bus line 10 has CPU 12, ROM
14, RAM16 is connected. CPU12 is ROM14
Control each part according to the program stored in.
An interface 18 and a display control circuit 24 are connected to the bus line 10. The display control circuit 24 controls the display on the screen of the display 2. The interface
Mechanism control circuit connected to bus line 10 via 22
28 controls ticket ejection processing from the issuing port 70 (see FIG. 1) and other mechanisms.

The bus line 10 further has an interface.
A transmission / reception control circuit 26 is connected through 20. The transmission / reception control circuit 26 controls transmission / reception of signals from the antenna 4. When a non-contact type prepaid card is inserted in the communication area of the automatic ticket vending machine, electromagnetic field coupling occurs between the antenna 4 and the antenna of the prepaid card, and data is transmitted and received. That is, the user can purchase the ticket without inserting the prepaid card into the automatic ticket vending machine.

A block diagram of a non-contact type prepaid card is shown in FIG. This prepaid card is also CPU42, ROM
44 and RAM 46, and the transmission / reception control circuit 54 controls transmission / reception from the antenna 56. The prepaid card itself is not provided with a power source, and is supplied with power through the antenna 56 by electromagnetic field coupling with the automatic ticket vending machine. Then, the supplied power is held in the power supply circuit 52, and thereafter, the power supply circuit 52 supplies power to the CPU 42 and the like, and the subsequent processing is executed.

FIG. 4 shows a flowchart of a program stored in the ROM 14 (FIG. 2) of the automatic ticket vending machine. First, the CPU 12 determines whether or not a communication command from the non-contact type prepaid card has been received (step S2). As described above, when the non-contact type prepaid card is inserted into the communication area of the automatic ticket vending machine, electromagnetic field coupling occurs. Then, the communication command is transmitted from the antenna 56 (FIG. 3) of the non-contact type prepaid card. This communication command is received by the antenna 4 (see FIGS. 1 and 2) of the automatic ticket vending machine, and the CPU 12 of the automatic ticket vending machine recognizes that the prepaid card has been inserted into the communication area.

After receiving the communication command, the ID code request command is transmitted from the antenna 4 of the automatic ticket vending machine to the prepaid card (step S4). The prepaid card which has received this ID code request command transmits an ID code signal. It is assumed that the ID code of this prepaid card is "1234". The CPU 12 of the automatic ticket vending machine determines whether or not the ID code signal of "1234" is received (step S6), and when it is received, the process proceeds to step S8.

The ID code signal received by the antenna 4 is
It is displayed on the display unit 2 (FIG. 2) under the control of the display unit control circuit 24 based on the instruction of the CPU 12 (step S
8). That is, the ID code "1234" is displayed on the display unit 2 in FIG. The user of the automatic ticket vending machine visually checks this display and confirms that the ID code is his or her own. After this confirmation, the user selects and inputs the purchase button 71 (step S10), and based on this, the automatic ticket vending machine carries out a sale process such as ticket issuing and reduction of the prepaid card (step S12). Then, the display on the display unit 2 is turned off to end the ticketing transaction processing (step S14).

As described above, the automatic ticket vending machine performs the ticket issuing transaction processing in a state where the automatic ticket vending machine does not contact the prepaid card. Therefore, if another person holds a non-contact type prepaid card and invades the communication area, interference may occur with the other person's prepaid card. In this case, in step S6 of FIG. 4, the automatic ticket vending machine receives the ID code signal of another prepaid card that has entered the communication area.

Now, it is assumed that the ID code of the other person's prepaid card that has intruded is "9876". Based on the ID code signal received in step S6, "9876" is displayed on the display unit 2 (step S8). For this reason, the user of the prepaid card with the ID code "1234" is
Since the D code and the display on the display unit 2 do not match, it is possible to reliably recognize that interference has occurred.

Since it is possible to clearly know the interference state in this way, it is possible to take appropriate measures such as canceling the transaction. That is, if the transaction is made without noticing the interference, after the ticket is issued, the reduction processing is performed on the prepaid card of another person (step S12).
However, in this embodiment, since the ID code is displayed on the display unit 2 (FIG. 1), it is possible to reliably prevent such an erroneous transaction from occurring.

In FIG. 1, for example, a confirmation button may be provided near the display unit 2 (not shown). Step
After the user confirms the ID code in S8 (Fig. 4),
By inputting this confirmation button, the prepaid card to be communicated is confirmed, and thereafter, interference with other cards will not occur. Therefore, it is possible to more completely prevent erroneous transactions.

Although the above embodiment has been described by taking an automatic ticket vending machine as an example, the present invention can be applied to an automatic ticket gate or an ATM in a bank as long as it is a device compatible with a contactless card.
For example, in an ATM or the like, a user may carry a transaction operation while holding a plurality of contactless cards. In such a case, if interference occurs with a card different from the card intended by the user, transaction processing will be performed for another account. Therefore, by displaying the ID code as described above, it is possible to effectively avoid interference and erroneous transactions between these plural cards.

[0024]

In the non-contact storage medium compatible device according to the present invention, the non-contact storage medium which is the current communication target can be clearly grasped. That is, when another non-contact storage medium enters the communicable area and an interference state occurs, the interference state can be surely recognized. Therefore, it is possible to avoid interference with other non-contact storage media and prevent erroneous transactions.
