RFID PN532 Mini

The PN532 is very powerful, and can pretty much do it all, such as read and write to tags and cards, communicate with phones (say for payment processing), and 'act' like a NFC tag. It can work with any NFC/RFID Type 1 thru 4 tag and has a read range of up to 5cm. You can use either I2C or SPI for communication protocol. This module has built in level shifter so you can safely use 5v logic for communication.
