The PN532 is the most popular NFC chip, and is what is embedded in
pretty much every phone or device that does NFC. It 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. If you
want to do any sort of embedded NFC work, this is the chip you'll want
NFC (Near Field Communications) is a way for two devices very close to
each other to communicate. Sort of like a very short range bluetooth
that doesn't require authentication. It is an extension of RFID, so
anything you can do with RFID you can do with NFC. You can do more
stuff with NFC as well, such as communicate bi-directionally with cell
Because it can read and write tags, you can always just use this for
RFID-tag projects. We carry a few different tags that work great with
this chip. It can also work with any other NFC/RFID Type 1 thru 4 tag
(and of course all the other NXP MiFare type tags)
The PN532 is also very flexible, you can use 3.3V TTL UART at any baud
rate, I2C or SPI to communicate with it. This chip is also strongly
supported by libnfc , simply plug in an FTDI cable and use the FTDI
serial port device to communicate - this lets you do NFC dev using any
Comes with: the PN532 breakout board including a tuned 13.56MHz
stripline antenna, 0.1" header, 2 jumpers/shunts and a 4050 level
shifter chip. We also toss in a Mifare Classic 1K card! (You can get
more tags from us) New in version 1.3: onboard power LED, 3.3V
regulator and an FTDI header so you can plug in an FTDI friend or FTDI
cable and use with libnfc.
We don\'t have a detailed tutorial up yet but we do have a quickstart
guide that will demonstrate the SPI interface on an Arduino and how to
read the 4-byte ID burned into the card. 
Size: 2" (51mm) x 4.7" (117.7mm) and 0.425" (1.1mm) thick.
