Introduction:

The ACR122U is a PC-linked contactless smart card reader/writer developed on the 13.56 MHz contactless technology. It is the world’s first CCID-compliant contactless card reader/writer that follows both ISO 14443 and ISO 18092. This device is designed to support  ISO 14443 Type A and B cards and NFC tags.

By making use of up to 424 kbps for NFC tag access and full USB speed of up to 12 Mbps, ACR122U can read and write faster and more efficiently. Furthermore, ACR122U is also PC/SC compliant which allows inter-operability across different applications and platforms. You can experience the convenience in using ACR122U, with its compact size and the various features it offers, for applications such as payment, access control, time and attendance, and mass transit.
