This is a Raspberry Pi NFC HAT based on the PN532 operating in the 13.56MHz frequency range. It supports three communication interfaces: I2C, SPI, and UART. NFC (Near Field Communication) is a wireless technology allowing contactless point-to-point data communication between devices within a short distance of 10 cm. It is widely used in applications such as access control systems, smart tickets, meal cards etc. Based on the popular NFC controller PN532 with multi-interface options, this HAT will easily enable NFC functions for your Raspberry Pi project. The board comes bundled with a single MIFARE Classic 1K NFC Card.
