  • Description
  • More

ACM1252U-Z2 is a small NFC reader module developed based on 13.56 MHz contactless technology, for fast and easy integration to embedded systems.

The ACM1252U-Z2 supports ISO 14443 Type A and B cards, and MIFARE®, FeliCa, and ISO 18092–compliant NFC tags.

It also supports other NFC devices with an access speed of up to 424 Kbps and proximity operating distance of up to 30 mm (depending on tag type used).

ACM1252U-Z2 also has an anti-collision feature that ensures only one card is accessed when multiple cards are presented simultaneously.

It is PC/SC-compliant and firmware upgradeable.

Its small size allows it to be integrated to compact machines.

It can be used with a detachable micro-USB cable that allows it flexibility to be located far from the USB host interface.
