PN532 NFC/RFID Controller Shield based on a PN532 chip is used for field communication close to 13.56MHz. This shield is equipped with an antenna onboard, so there is no external antenna coil. It is compatible with SPI, IIC, and UART interfaces to communicate. When using it, directly stack it onto UNO R3 control board.
