This RC-522 NCF RFID module, as its name implies, is based on a RC- 522 chip and used for 13,56MHz near field communication. The module is equipped with onboard antenna, thus no external antenna coil is needed. It is compatible with SPI, IIC and UART interface for communication. With NFC library support for Arduino, it is quite convenient for development of products with NFC functions.
Features:
- Effective communication distance of 1 cm
- Supports switching of SPI, IIC and UART interface
