The MF522-AN module is based on the original Philips MFRC522 chip and is designed as a cost-effective, easy-to-use RFID card reader. It is suited for both user equipment development and advanced applications where RF card terminals are needed. The module is adaptable for integration into various reader molds and operates using a 3.3V power supply. It communicates reliably with CPUs through an SPI interface, ensuring stable operation over a card reading distance.
