The NFC/RFID Shield for Arduino is based on the PN532 chip and is designed for field communication at 13.56 MHz. It comes with an onboard antenna and is compatible with SPI, IIC, and UART interfaces for communication. This Shield must be stacked directly onto the VMA100 UNO control board to function.
