Smart card

A smart card is a chip attached to or embedded in CPU cards, logic encryption cards, RFID labels and other smart cards (or IC cards). It contains a microprocessor, an input/output interface and a memory (e.g., EEPROM), which performs data operation, access control and storage functions. We have four product series in this product line: NFC tag, logic encryption card, CPU card and reader. They are widely used in public transport cards, access control cards, student ID cards and membership cards.

With our technological capability development and R&D capabilities in EEPROM, and responding to the needs of the downstream market, we have developed smart cards by extending the EEPROM business to the application side. Supported by China's sophisticated integrated circuit supply chain, Giantec provides global customers and markets with highly cost-effective security and identification chip solutions. Our products are well received by customers around the world for their stability and reliability, and are clearly differentiated in the market.
