ABSTRACT:
According to a portable electronic apparatus processing system of this invention, when an IC card receives instruction data, it checks if a function code can be completely input. If the function code is not completely input, the IC card sets data "FF" (hexadecimal code) as the function code, and outputs it to an IC card reader/writer. When the IC card reader/writer outputs an instruction to the IC card, it appends sequential number data to the instruction. The IC card executes processing corresponding to the supplied instruction. When the IC card outputs the processed result to the IC card reader/writer, it appends the sequential number data from the IC card reader/writer to the processed result and outputs it.
