Dual interface card

Dual interface card (also known as combination card/dual terminal interface card) is a multi-functional card that has both contact and non-contact interface communication. It integrates the convenience of non-contact IC card and the safety and reliability of contact IC card, making it an excellent carrier for one card and representing the main development direction of IC card in the future.Dual interface card is not only suitable for the city public transportation, highway toll and electronic wallet and other convenient occasions, but also to meet the safety, reliability of more attention to the needs of financial services, e-commerce, card market has become another hot competition.

There are three types of dual interface CARDS:

1. Contactless smart card system and contactless smart card system are only physical combination in one card, two EEPROM, two systems are independent of each other.

2. Contactless smart card system and contactless smart card system operate independently from each other, but share part of the storage space in the card.

3. The contactless smart card system and contactless smart card system are completely integrated. The contactless and contactless running states are the same, and they share one CPU management.Of the three kinds of dual-interface IC CARDS, only the last dual-interface IC card is the real non-contact dual-interface CPU card.
