Print Friendly, PDF & Email

MFRC522 is applied to the highly integrated read and write 13.56MHz contactless communication card chip, NXP launched by the company for the “table” application of a low-voltage, low-cost, small size of non-contact card chip, smart meters and portable handheld devices developed better choice. The MFRC522 use of advanced modulation and demodulation concept completely integrated in all types of 13.56MHz passive contactless communication methods and protocols. In addition, support rapid CRYPTO1 encryption algorithm, terminology validation MIFARE products. MFRC522 support MIFARE series of high-speed non-contact communication, two-way data transmission rate up to 424kbit/s.
