789-ADA Adafruit PN532 NFC/RFID Controller Shield for Arduino + Extras
789-ADA Adafruit PN532 NFC/RFID Controller Shield for Arduino + Extras
US$61.52
We've taken our popular Adafruit PN532 breakout board and turned it into a shield - the perfect tool for any 13.56MHz RFID or NFC application. The Adafruit NFC shield uses the PN532 chip-set (the most popular NFC chip on the market) and is what is embedded in pretty much every phone or device that does NFC. This chipset 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. While the controller has many capabilities, our Arduino library currently only supports reading/writing tags, and does not support phone-to-shield communication, tag emulation (which requires an external 'secure element' only available from NXP) or other more advanced features at this time.
