PROBLEM TO BE SOLVED: To provide a noncontact IC card with display function capable of displaying information in the IC card with a simple structure without being affected by carried place. SOLUTION: A power supplier 3 obtains a power from an electromagnetic guide wave from a reader/writer which is received by a receiving antenna 1, and supplies this to each part. Then, an I/O control part 7 controls the communication with the reader/writer according to a command from the reader/writer, and at the same time, if the received command is a data displaying instruction, it controls a line driver 8 and a column driver 9 to display data on a ferroelectric liquid crystal panel 10. |
