RC522 is a highly integrated read and write 13.56MHz contact-less communication card chip, for applications of a low-voltage, low-cost, small size of the non-contact card chip to read and write, smart meters and portable hand-held devices. The RC522 use of advanced modulation and demodulation concept completely integrated in all types of passive contact-less communication methods and protocols. 14443A compatible transponder signals. It can handle the ISO14443A frames and error detection. In addition, it support rapid CRYPTO1 encryption algorithm, terminology validation products. RC522 support series of high-speed non-contact communication, two-way data transmission rate up to 424kbit/s.
