JPS6266376A - Card and discriminator for truth and falsehood of card - Google Patents

Abstract

PURPOSE:To decide that a card equipped with no reading means is false even when a card where a transaction processing code and ID information are stored is reproduced by providing the transaction processing card with a reading means for a pattern for truth/falsehood discrimination. CONSTITUTION:When the IC card 1 is set on the card handling mechanism 11 of a terminal equipment, the CPU of the IC card 1 discriminates whether or not a readout command is received from the terminal equipment. When the CPU 12 of the terminal equipment transmits a readout command to the IC card 1, on the other hand, the CPU of the IC card 1 reads the optical pattern 11a of the card handling mechanism 11 of the terminal equipment and transmits the read optical pattern information to the terminal equipment. The CPU 12 of the terminal equipment receives the optical pattern information from the IC card 1 and compares it with optical pattern information in a RAM 14; when both pieces of pattern information conform with each other, the transaction processing of the IC card 1 is carried out and when not, a display and a warning of an illegal card are made.

Description

[Detailed description of the invention] <Industrial application field> The present invention relates to a card and a card authenticity determination device.

<Summary of the Invention> The present invention provides a transaction processing card with a means for reading a pattern for determining authenticity, and a card equipped with the reading means is determined to be "authentic", and a card not equipped with the reading means is determined to be "false". It was designed to do so.

<Prior art> Generally, transaction processing cards such as magnetic cards, IC cards (cards with built-in integrated circuits), and laser cards used in bank automatic teller machines, etc. have a code such as a recited number in addition to a transaction processing code. ID information is stored.

Conventionally, a card authenticity determination device in such an automatic payment machine or the like compares ID information read from the card with ID information input from a numeric keypad or the like to determine the authenticity of the card.

<Problems to be Solved by the Invention> However, in such a method of determining the authenticity of a card, there is a risk that an abuser may read his or her own or another person's transaction processing code or ID information and copy the card. In this case, there is a problem in that the discrimination device discriminates the duplicated card as "authentic" if correct ID information is input at the time of transaction.

SUMMARY OF THE INVENTION In view of the problems of the prior art described above, it is an object of the present invention to provide a card and a card authenticity determination device that can determine the authenticity of a duplicate transaction processing card.

<Means for solving the problem> In order to solve the above MQ problem, the present invention provides a means for reading a pattern for determining authenticity on a transaction processing card, and a card equipped with this reading means is recognized as "authentic". On the other hand, cards that are not equipped with this reading means are determined to be "fake."

<Operation> With the above configuration, the non-inventive system can process transaction processing codes and ID information (
Even if a card with a memorized password (recited number, etc.) is duplicated, the card will be determined to be fake if it is not equipped with a means to read the pattern for determining authenticity.

<Example> Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 1 is an explanatory diagram of an IC card 1 according to an embodiment of the present invention.
It has an optical reader 3 such as e), an IC 2, and a terminal 4 of the optical reader 3.

IC2 includes a central processing unit (CPII), read-only memory (ROM), and random access memory (RAM).
A CPTT execution program as shown in FIG. 3 is stored in the ROM. RAM is an area where ID information such as transaction processing codes and password numbers are stored, and C.
It has a PU work area, etc.

FIG. 2 is a block diagram showing an embodiment of a card transaction device (terminal device) having a card authenticity determination device of the present invention, and includes a card handling mechanism 11. As shown in FIG.

The card handling mechanism 11 includes a terminal connected to the terminal 4 of the card 1, a keyboard into which transaction information and ID information are input,
It has a display screen for displaying a fraudulent card warning, etc., and a card transport mechanism ring, and an optical pattern lla for determining card authenticity is arranged in the card insertion section of the card transport mechanism.

This terminal device further includes a central processing unit (CPTJ) 12, a read-only memory (ROM) 13, a random access memory (RAM) 14, and modulates and demodulates input/output signals to communicate with an external computer (not shown). MODEM/
It has a network control section 15. The ROM 13 stores an execution program as shown in FIG. 4, and the RAM 14 has an area in which the above-described optical pattern information for determining card authenticity is stored, a work area for the CPU 12, and the like.

Below, the CPU of the IC card 1 and the CPU 12 of the terminal device
operate as shown in FIGS. 3 and 4, respectively.

First, when the IC card 1 is set in the card handling machine $11 of the terminal device, in step (hereinafter referred to as ST) 1 of FIG. determine whether In STI 1 of FIG. 4, when the CPU 12 of the terminal device sends a reading command to the IC card 1, the CPU of the IC card 1
As shown in ST2 of FIG. 3, the optical reader [3 reads the optical pattern 11a of the card handling mechanism 11 of the terminal device, and in the next step (ST3), the read optical pattern information is transmitted to the terminal device.

The CPU 12 of the terminal device executes I at 5T12 in FIG.
Receive optical pattern information from C card 1, continue <5T1
3, it is compared with the optical pattern information in the RAM 14. Next, in 5T14, it is determined whether or not the two pattern information match, and if YES, the process proceeds to STI 5 to perform transaction processing for the IC card 1 (5T4 in Figure 3).

To explain this transaction processing, the CPU 1 of the terminal device
2 requests and reads the transaction processing code and ID information from the IC card 1, and sends this ID information and card handling mechanism 11.
ID information entered repeatedly on the keyboard is compared.

If they match, the transaction processing code read from the IC card 1 and the transaction information entered using the keyboard are sent to the M
It is transmitted to an external computer via the ODEM/network control unit 15 and transaction processing is performed.

At 5T14 in FIG. 4, if the patterns do not match, the CPU 12 of the terminal device branches to 5T16,
Display and warn that the IC card 1 is an unauthorized card. In the continuation <5T17, the process instructed by the terminal device staff is performed.

That is, in this embodiment, the terminal device determines authenticity based on whether or not its own optical pattern lla is read by the IC card 1, and the IC card with only the transaction processing code and ID information copied is equipped with a reading device. “False” because it is not
It is determined that In this case, the transaction processing card is not limited to an IC card, but may also be applied to a magnetic card or the like.

In the embodiment described above, the authenticity determination is performed on the terminal device side, but it may be performed on the IC card side instead. In this case, authenticity determination pattern information is stored in advance in the RAM of the IC card 1, and the transaction processing code and ID information are configured not to be transmitted to the terminal device if they do not match the read pattern of the terminal device. If the terminal device does not receive the above data within a predetermined time after transmitting the reading command to the IC card, the terminal device determines that the card is "fake" and does not process the transaction.

<Effects of the Invention> As explained above, in the present invention, since the card is provided with a means for reading the pattern for determining authenticity, accurate determination of authenticity is possible even if the data on the card is duplicated.
