A card identification system comprises generally a card reader head composed of a light generating unit, a main circuit A/D convertion unit, a transmitter/receiver rack, a MF keyboard decode unit, a LCD unit and a CPU, and a reader device composed of a MF keyboard decode unit, a LCD unit, a EEPROM unit, a CPU and a driver device thereof. This disclosure is characterized in adapting an infrared ray scanning method to the card reader head therein to precisely detect a symbol on a identification card which can be unlimitedly made from a variety of materials. The identification code marked on the card may be made by printing or perforating a symbol or sticking up a tape, or a sticker thereon.
