IC card and IC card reader.

摘要

An IC card includes an integrated circuit composed of a transmitter/receiver, a processor, a memory, and a display controller; a display, and control switches for successively switching data displayed on the display. Desired data stored in the memory can be displayed on the display by a command delivered through the transmitter/receiver or actuation of the control switches. An IC card reader for reading the IC care includes signal transmitting and receiving circuits for transmitting signals to and receiving signals from the IC card, and a control unit for displaying the stored data on the display of the IC card dependent on processed results.
