A smart card is provided to enable a user of a traffic card and an e-ticket card to understand desired information related to the card anytime/anywhere by including an information display device. An information IC chip(101) stores and outputs remainder, mileage, seat number, and time information. A driving IC chip(102) operates the information display device by outputting a control signal based on the information received from the information IC chip. The information display device(103) displays characters, numbers, and symbols by receiving the information and the control signal from the driving IC chip. An interface device(104) is connected to an external device through a connector. A power supply unit(105) supplies power to each component. A switch(106) turns on/off the power and selectively switches the displayed information. The display device is an LCD(Liquid Crystal Display), and includes the first display part displaying the information in the characters or the numbers, and the second display part displaying the information in the symbols. |
