This RFID kit makes it possible to read and describe all RFID tags that work on the 13.56MHz frequency. The MF RC522 uses advanced modulation and demodulation integrated in the 13.56MHz contactless chips. This module also supports ISO14443A frames and error detection together with the fast CRYPTO1 encryption algorithm.
