Abstract

PROBLEM TO BE SOLVED: To obtain a method for confirming data for identifying an IC card realizing the speedy reproduction of the IC card by reading data for identification stored in a memory, recording the IC card after converting to ciphered data and reading/deciphering this recorded ciphered data at the time of confirming data for identification, so as to confirm data for identification. SOLUTION: Data for identification stored in the memory of the IC chip of the IC card are read by an IC memory reading means 7. After converting read data for identification to ciphered data by a ciphering means, they are sent to a code recording and writing means 11 through a control means 14 and recorded in the state of a bar code as a code for mechanically reading on the side surface part of a card substrate by using laser. When the necessity of confirming data for identification arises, the code for mechanically reading recorded in the IC card is read by a reading means. Next, ciphered data for identification are sent to a deciphering means 10 to be deciphered.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to an IC for an IC card.
The present invention relates to a method for confirming identification data stored in a memory of a chip. In particular, individual IDs such as personal identification information and card identification information stored in the memory of the IC chip are stored.
The present invention relates to a method for confirming identification data which is effective when identification data individually provided for each C card cannot be read due to a failure or the like.

[0002]

2. Description of the Related Art In recent years, chip cards in which IC chips such as microcomputers and memories are mounted or built-in,
Research on cards called memory cards, microcomputer cards, and electronic cards (hereinafter referred to as IC cards) has been made.

[0003] Such an IC card has a larger storage capacity than a conventional magnetic card. Therefore, in the case of a bank, the history of deposits and savings is stored instead of the bankbook, and in the case of credits, the history of shopping and the like is stored. Has been used. These IC cards are usually configured by embedding a modularized version of all electrical elements including an IC chip and a circuit pattern in a recess formed in a card base material. The module is provided with an IC chip provided with control means including a CPU and storage means including a memory, and connection terminal electrodes for electrically and mechanically connecting to an external data processing device. The connection terminal electrodes of the module are embedded in the recesses formed in the material so as to be exposed on the card surface.

[0004] In addition to the above-mentioned contact type IC card, a non-contact type IC card is known. This non-contact type IC card has a module configured by connecting an IC chip and a coil for transmitting and receiving a signal in a non-contact manner with an external processing device, built in the IC card. By providing a control means comprising a CPU and a storage means comprising a memory capable of storing various data as in the case of a contact type IC card, signals can be exchanged without contacting an external processing device. It was done.

[0005] Usually, in the memory built in these contact-type or non-contact-type IC cards, the manufacturer of the IC card stores them in the memory in order to identify each IC card by product management or the like. There is a case where card identification information or personal identification information such as a personal identification number or an ID number which is set arbitrarily by an IC card user and used as collation information when confirming the identity of the IC card user is stored. Especially I
When using a C card, first, for security reasons, IC
PIN or ID to confirm the identity of the card user
The personal identification information corresponding to the number is input to the IC card from the input device, and is compared with the personal identification information registered in advance in the memory of the IC card, and the entered personal identification information and the registered personal identification information are compared. In many cases, a system that can perform the subsequent processing by the IC card only when the information matches the information is adopted.

[0006] Of the individual information, the card identification information is stored in the memory of the IC card during the manufacturing process of the IC card, and the personal identification information is stored in the memory of the IC card before shipment to the IC card user after the product is shipped. Is generally stored in the storage means of the IC card at the stage. And usually,
In order to maintain the security of the IC card, the card identification information and the personal identification information once stored in the memory are systematized so that they cannot be easily read. Preventing.

However, the IC chip embedded or embedded in the IC card breaks down or is damaged for some reason during the manufacturing process, and becomes a defective product in the product inspection before shipment, and the shipment of the IC card is stopped. Manufacturing needs may arise. In some cases, the card identification information stored in the memory provided in the IC chip cannot be read due to the failure or damage of the IC chip. Even if it is desired to immediately remanufacture an IC card in which the IC card is stored in the memory, the card identification information of the IC card cannot be easily confirmed, and there is a risk that the efficiency of the IC card manufacturing process will be hindered. . In particular, when a large number of defective IC cards are found in the inspection process during the production of a large number of IC cards, it takes time and time to check the card identification information of each defective IC card from the material data. There is a risk that problems such as delay in delivery may occur.

Further, after the IC card is shipped or passed to an IC card user, the IC chip embedded or built in the IC card for any reason may be damaged or damaged.
There is a case where reading of personal identification information stored in a memory provided in an IC chip becomes impossible. Also in this case, when the IC card is remanufactured, the personal identification information and the card identification information are immediately read from the memory provided on the IC chip, and the IC card cannot be remanufactured. It is necessary to confirm information by examining records at the issuer,
There is a problem that it takes time and remanufacturing time.

[0009]
