PROBLEM TO BE SOLVED: To provide an IC card capable of driving a display unit without using a battery.SOLUTION: An IC card 1 includes: an IC chip 20 that has a non-contact interface 21 and contact interface 22 performing data input/output mutually exclusively, and a non-contact OS 23 processing data that is input from the non-contact interface 21 and outputting it to a memory 25; a non-contact communication antenna 2 that receives data in a non-contact manner and transmits the received data to the non-contact interface 21; a pressing button 6 and switch 7 that switch between permitting and restricting data transmission from the non-contact communication antenna 2 to the non-contact interface 21; a control microcomputer 10 that, when the data input/output to/from the non-contact OS 23 via the contact interface 22 is enabled, controls display contents on a display unit 5 on the basis of data obtained from the memory 25; and a power-securing antenna 3 to which power is supplied in a non-contact manner and that transmits the supplied power to the display unit 5 and the control microcomputer 10. |
