Abstract

The utility model provides an IC card with a display function, and belongs to the smart card field. The IC card with the display function comprises a communication unit for receiving an external data signal through a communication interface and demodulating and decoding the data signal to obtain internal storage data, the data signal generating voltage of a preset magnitude through the communication unit; a control unit which is connected with the communication unit and used for receiving the internal storage data and displaying the internal storage data on a bi-stable state display screen, the electric power source of the control unit being the voltage generated by the communication unit; and the bi-stable state display screen connected with the control unit and used for displaying the internal storage data. The IC card provided by the utility model can display for a long time without any need of built-in batteries, and a user can conveniently read information stored in the IC card at any time.
