An embodiment of the present invention will be described with reference to FIG.

A magnetic head 2, an electromagnet 3, a fraudulent mark stamping machine 4, and a card stopper 5 are sequentially arranged from the front on the card running surface 1 of the collating machine. In addition, a control unit 6 and a control circuit 7 are arranged separately from these.

The card is inserted into the card running surface 1, the magnetic information of the magnetic stripe is read by the magnetic head 2, and the magnetic information is sent to the control unit 6. The control unit 6 checks with the card management company using the communication line. That is, when used in a terminal, the terminal sends the magnetic information of the magnetic stripe to the card management company online and checks the validity of the card based on the transmitted magnetic information of the magnetic stripe.

The card management company sends the contents of the magnetic information to the control unit 6. The control unit 6 sends a signal to the microchip 8 of the control circuit 7, and the microchip 8 sends a signal to each of the drivers 9, 10, 11 so that each of the drivers 9, 10,.
11 operates the electromagnet 3, the improper mark stamping machine 4, and the card stopper 5.

If the card is valid, that is, a positive card, the card stopper 5 is lowered by a signal from the driver 11 and normal traveling is performed to send the card to a normal processing position.

[0015] However, if the card is lost or stolen, non-transactional information is transmitted to the terminal online, and the terminal informs the card management company that the card is not valid, ie, reports that there is an unauthorized card. And inform the user that the card is not valid.

If the card is lost or stolen, the information is sent to the control unit 6, and the control unit 6 sends the information to the microchip 8 of the control circuit 7, and the microchip 8 sends the information to the drivers 9, 10, and 11. The driver 9 operates the electromagnet to destroy the magnetic information of the magnetic stripe while the driver 11 stops the card without lowering the card stopper 5 by sending a signal. Activate 4 and engrave, for example, "Not available".

As described above, when used improperly, not only is the magnetic information of the magnetic stripe destroyed, but also a mark such as "cannot be used" is imprinted on the card, so that an invalid card, that is, an invalid card can be used. This has the effect of disappearing.

Generally, when a card is used in a terminal of the information means, the terminal transmits the magnetic information of the magnetic stripe to the card management company online. The card management company checks the validity of the card based on the contents of the magnetic stripe transmitted online. Then, as described above, if the card is a fraudulent card, the information indicating that the transaction is not possible is transmitted online to the terminal so that the transaction is not established.

Even when the terminal is not online with the card management company, the terminal manages the invalid information received from the card management company, and when the card is used, the invalidity in the terminal is determined offline based on the invalid information. Checking the sex. Here, as in the case of online, after checking the validity, information on whether or not the transaction is available is published in a journal, and the card user is contacted to terminate the transaction.
