The Adafruit PN532 NFC / RFID Controller Breakout Boards are the perfect complement to Adafruit's range of RFID tags and cards. Based on the PN352 NFC chip, the most popular chip on the market, these boards are very capable and flexible. They can read and write NFC/RFID Type 1 to 4 tags and cards, they can appear to other devices to actually be a card and they can perform bi-directional communication with mobile phones and tablets.

Talking to the boards is simple, using 3.3V TTL serial communications at any baud rate, I2C or SPI. Because the NFC chip is so popular it is supported by the Open Source package libnfc which will let you control a board via an FTDI cable using any Linux, Mac or Windows computer. Each board has an FTDI header for just this purpose. The boards have a built in 13.56MHz antenna for compatibility with popular cards and tags. Adafruit have produced a tutorial to get you started which has links to useful libraries and other downloads.

Supplied with the PN532 breakout board, 0.1in. header strip, a pair of jumpers, a 4040 level shift chip and an RFID card.
