<p>PURPOSE:To facilitate a mass-production and to improve a generality by providing a non-volatile memory storing a processing program writing program, mounting the non-volatile memory capable of being electrically erased on a card body, and thereafter writing a processing program therein. CONSTITUTION:In producing an IC card, in a program memory 3, a processing program writing program is previously written, in an area 8 of a program memory 4, a start address in the memory 3 is stored and mounted on a card body 5 to complete the IC card. After the card is completed, when the card body 5 is mounted to the terminal, by the start address, the processing program writing program is read from the memory 3, a processor 2 operates based on this and performs a writing to the program memory 4 of the processing program inputted from a terminal. At this time, in the area 8, a rewriting of the start address is done. Thereby, a mass-production can be done and in the IC card, any processing program can be written any time, so that a generality is improved.</p> |
