Adafruit PN532 NFC/RFID controller breakout board Microcontroller ENABLE pin so you canThe 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.
