This module can be directly loaded into the various reader molds, very convenient. It is very easy to use as there are tones of library and examples, especially using Arduino. It is based on the MF522-AN module and ready with the RFID antenna built in. MFRC522 are similar to MFRC500 or MFRC530 , but also have the characteristics and differences. Communication between it and the host SPI mode helps to reduce the connection narrow PCB board volume, reduce costs.

MFRC522 supports MIFARE series of high-speed non-contact communication, two-way data transmission rate up to 424kbit/s. It supports rapid CRYPTO1 encryption algorithm, terminology validation MIFARE products. The digital part of to handle the ISO14443A frames and error detection. 14443A compatible transponder signals.
