ABSTRACT:
The present invention aims to provide an IC card, requiring no special additional devices, not causing a liquid leakage of an aqueous electrolyte, requiring no battery, and capable of displaying information easily and cheaply by internally generated electric power and remaining the information even after the voltage is stopped applying. An IC card of the present invention has an electric power generator capable of generating electric power by an external stimulus and a display driven by the generated electric power so as to display information. The IC card of the present invention preferably have aspects of that the electric power generator is a piezoelectric transducer, a nonvolatile memory for storing information displayed on the display is provide, the nonvolatile memory is a ferroelectric memory, the display is formed by an electrochromic display device, and the electrochromic display device is an all solid-state electrochromic display device.
