Abstract

PURPOSE:To develop high security effect and to increase an access speed by mounting an IC chip, wherein a signal transmitting/receiving exclusive circuit and a memory capable of writing read/write possible and impossible password function and data memory function at the time of the publishment of a card are fused, in the board of the card. CONSTITUTION:A single IC chip wherein a gate array 2 becoming a data signal transmitting/receiving exclusive circuit and a memory 3 are fused is mounted in the card board 1 of an IC card and sheet-like electromagnetic coils (4A) - (4D) mutually transmitting a data signal between a reader/writer and said coils through electromagnetic force are mounted in said card board 1. A white card 1A is formed at the time of manufacturing and the writing of a password for recovering password function, the allotment of a function password and the allotment of the memory at every function are performed in a card publishing stage and the writing of the function password is performed. The card 1 is inserted in the reader/writer to give the function password and, when said password coincides with the written function password, the reading/ writing of the allotted memory is performed. In case of non-coincidence, the number of errors is counted and, when the count value exceeds a set value, read/write becomes impossible.

(Conventional technology) One of the conventionally known IC carts in the Riko Building has an IC chip that combines a CPU and memory built into a card board. The control circuit that controls procedures etc. is a general-purpose CPU
However, no matter how much effort was made to create a security system that operated under the control of the CPU, it was impossible to protect the secret of its performance, and it was beyond the realm of general-purpose use. In other words, the control element is a combination of general-purpose CPU hardware and software such as I9 security procedures, and is pre-installed at a semiconductor manufacturer or the like.

(Problems to be Solved by the Invention) As described above, conventional IC cards are configured to use the CPU for the identification function to improve security. Although the security effect is higher than that of magnetic cards, which were the mainstream of cards, the use of cards by people on the card manufacturer's side, such as producers of software programs such as security procedures and engineers involved in repairing and modifying systems, is effective. It is not possible to completely prevent the leakage of secrets, and as a result, there is a need for a card with higher security.
