ACR122U

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 not only MIFARE® and ISO 14443 Type A and B cards but also FeliCa and NFC tags. By making use of up to 424 Kbps read/write speed for NFC tag access and up to 12 Mbps for USB full speed, ACR122U can efficiently read from and
write to various contactless cards/tags. It is also PC/SC-compliant which allows interoperability 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.
