Abstract

An IC card includes a card reader interface for receiving data from a card reader, a microprocessor for decoding, decrypting and categorizing the data or converting the data into displaying format, an electrically erasable programmable read only memory for storing the data, a display screen, a display driver for driving the display screen, and a solar battery for providing power, whereby it is unnecessary for a user to look for a card read in order to read the data stored in the IC card.

Claims

1. An IC card with a display screen comprising:

a card reader interface for receiving data from a card reader;

a microprocessor for decoding, decrypting and categorizing said data or converting said data into displaying format;

an electrically erasable programmable read only memory for storing said data;

a display screen;

a display driver for driving said display screen; and

a solar battery for providing power.

2. The IC card with a display screen as claimed in claim 1, wherein said data stored in said electrically erasable programmable read only memory is selected by contact switches.

3. The IC card with a display screen as claimed in claim 1, wherein said solar battery is connected with a secondary cell.

4. The IC card with a display screen as claimed in claim 1, wherein said electrically erasable programmable read only memory has a character producing program for converting said data into English or Chinese characters for showing in said display screen.
