PN532 NFC/RFID controller breakout board - v1.6 Air monitoring for Raspberry Pi 91" OLED Display: Provides real-timeThe 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 to use! NFC (Near Field Communications) is a way for two devices very close to each other to communicate.
