MULTIFUNCTIONAL CARD USE SYSTEM

摘要

PURPOSE:To improve the capability in excluding the wrong use by recording a part of a logic part or a data part of a work processing program in a memory card and connecting and synthesizing both parts at the time of using the memory card to complete a program for a prescribed transaction object work as an executable program. CONSTITUTION:An address and contents (a part of a program or data) to be rewritten of a program 52 peculiar to a work and a table of data length of contents are stored for each work in an IC card 1. The program 52 peculiar to the work is partially rewritten with contents of an IC card non-volatile memory 12. A user inserts the IC card 1 to a transaction device 2 and inputs a card owner password code. After the inputted password code is identified by a microprocessor 11 of the IC card 1, the microprocessor 11 of the IC card 1 sends a synthesizing program of the corresponding work or the address and contents of data to a work program control program 51, and the program 52 peculiar to the work is synthesized there.
