M5Stack Mini RFID Unit

M5Stack Mini RFID Unit consists of an MFRC522 chip in a compact package. The MFRC522 operates in the 13.56MHz frequency band and uses the modulation and demodulation principle to interact with the proximity RF card. The M5Stack Mini RFID Unit can realize the card reading and writing device's function, identify and record multiple card information, and encode and authority an RF card. The Mini RFID Unit can establish applications such as an access control system, punching system, warehouse goods storage, and community vehicle access registration.
