Abstract
A method for modifying program in EEPROM of an IC smart card system. First, save the operating program of IC smart card system in a ROM, the operating program has a function of Add Command. Next, increase the content of the command code before formatting the IC smart card, wherein the increased command code and the actual content are saved in an EEPROM. Then, formatting the IC smart card to define the file segment of the EEPROM, and finally input personal data in the IC card to complete the card activating procedure. By using the program modification method, the time for the IC card producing is reduced and the efficiency is improved when there are small changes of the functions of the IC card.
Claims17
A method of modifying an operating program of an Integrated Circuit Card (ICC), comprising:
- saving the operating program of the Integrated Circuit Card in a ROM, wherein the operating program can add a command code;
- adding the command code before pre-personalization of the IC card, wherein the command code and the content being saved in a non-volatile memory of the IC card;
- formatting the IC card in order to define a file segment of the non-volatile memory;
- and
- proceeding a personalization of the IC card.
A method of modifying an operating program of an Integrated Circuit Card (ICC), comprising:
- saving the operating program of the Integrated Circuit Card in ROM, wherein the operating program can add a command code;
- adding the command code by using a computer which being connected to an Interface Device (IFD) of the IC card, the command code and content being saved in the Electrically Erasable and Programmable ROM (EEPROM) of the IC card;
- formatting the IC card in order to define a file segment of the EEPROM, wherein the file segment is located behind the command code and the content;
- and
- proceeding the personalization of the IC card.
