The ACR122 is a PC-linked contactless smart card reader/writer developed on the 13.56MHz Contactless (RFID) Technology and followed the ISO/IEC18092 Standard for Near Field Communication (NFC),   supporting not only Mifare® ISO 14443 A and B cards but also NFC and FeliCa contactless technologies.
  The ACR122 is a USB Plug and Play device with CCID compliance. It is ideal for both secure personal identity verification and online micro-payment transactions. Typical applications of the ACR122 reader include access control, e-payment, e-ticketing for events and mass transit, toll road fare collection and network authentication.
  By making use of up to 424 Kbps for NFC Tag access and full USB speed of up to 12 Mbps, the ACR122 can read and write faster and more efficiently. The proximity operating distance of ACR122 is up to 5 cm, depending on the type of contactless tag in use. Operating distance can be extended on request by adding an RF boaster, so the ACR122 is suitable for logistics and supply chain management.
  In order to increase the security level, the ACR122 can be optionally integrated with an ISO7816-3 SAM slot. In addition, the ACR122 is available in module form for easy integration into bigger machines, like POS terminals, physical access devices and vending machines.
  With excellent performance and flexibility, you can experience the convenience and benefits offered by the ACR122.
