The RC522 RFID module is a 13.56 MHz RFID reader/writer based on the MFRC522 IC from NXP. It uses the SPI protocol for communication and is commonly used in contactless communication applications. The module includes one RFID card and one key fob tag compliant with the ISO/IEC 14443 Type A standard. It's ideal for access control systems, attendance tracking, and embedded projects using microcontrollers like Arduino, ESP32, and Raspberry Pi.
