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
MifareŽ 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 also PC/SC compliant which allows interoperability
for different applications development. 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 212 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.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.
