Contactless card is also called radio frequency card, it is a new technology developed in recent years, combined radio frequency identification technology and IC card technology, solved the problem of no power and contactless, it is an important improvement in electronic device area.

Our contactless card has adopted the most advanced American AIT process. The annual capacity for contactless card is 25 million pcs.
