Dual Interface Card:

Dual Interface Card is a microprocessor card which has one chip with contactless & contact interfaces. It can be used at banking, transportation, healthcare, ID, Government and other areas that need larger memory and higher security than a standard contactless & contact memory card.

Thanks mature chip technologies from players like NXP, Infineon, ST, FUDAN, HuaHong etc and related OS & solution suppliers. After years’ experiences of production & development, now we are proudly ready to support your project of Dual Interface Card with superb and stable quality for mass production.

We hava 2 ways to help you on Dual Inter-face Card supply.

1. Chip consign and OEM Card making service. If you already defined the chip model & source likes from NXP, we can help you on card making. You are welcome to consign chips to our facility for card’s building.

Here after are the typical Dual Interface chips from NXP JCOP series:
