MF RC522 is a highly integrated read-write card chip used in 13.56MHz contactless communication. It is a low-voltage, low-cost, small-sized non-contact read-write card chip launched by NXP for the application of "three watches". It is a good choice for the development of smart meters and portable handheld devices. MF RC522 utilizes advanced modulation and demodulation concepts and fully integrates all types of passive non-contact communication methods and protocols under 13.56MHz. Supports 14443A compatible transponder signals. The digital part handles ISO14443A framing and error detection. In addition, it also supports a fast CRYPTO1 encryption algorithm, which is used to verify MIFARE series products. MFRC522 supports higher-speed contactless communication of the MIFARE series, and the two-way data transmission rate is as high as 424kbit/s. As a new member of the 13.56MHz high-integration read-write card series chip family, MF RC522 has many similarities with MF RC500 and MF RC530 but also has many characteristics and differences. The communication between it and the host adopts the SPI mode, which is beneficial to reduce the connection, reduce the size of the PCB board, and reduce the cost. ?Introduction to RFID Module? The MF522-AN module adopts the Philips MFRC522 original chip to design the card reading circuit, which is easy to use and low in cost. It is suitable for users of equipment development, card reader development, and other applications, and users who need to design/produce RF card terminals. This module can be directly loaded into various card reader molds. The
