  • IC card system and method for securing the system
    Patent number: 6283369
    Abstract: A control circuit receives data input by the user through an operable monitor, attaches a data-encoding instruction to the input data, and supplies the instruction-attached input data to an IC card reader/writer. Upon receiving the instruction-attached input data, the IC card reader/writer reads encoding key data stored in an IC card, thereby encoding the data and returning it to the control circuit. The control circuit, in turn, modifies the returned encoded data in the form of communicable data, and supplies a communication circuit with the modified encoded data and an instruction to transmit the data. Upon receiving the modified encoded data and instruction, the communication circuit transmits the modified encoded data to a host computer via a communication line.
