The PN532 is a highly integrated transmission module for contactless communication at 13.56 MHz including microcontroller functionality based on an 80C51 core with 40 Kbytes of ROM and 1 Kbytes of RAM. The PN532 combines a modulation and demodulation concept completely integrated for different kinds of contactless communication methods and protocols at 13.56 MHz with an easy-to-use firmware for the different supported modes and the required host controller interfaces.
It works as RFID reader/writer,1443-A card or a virtual card and also supports NFC with Android phone. It is also compatible with Arduino.
