【Introduction to RC522 chip】
MF RC522 is a highly integrated read-write card chip used in 13.56MHz contactless communication. It is a low-voltage, low-cost, small-volume non-contact read-write card chip launched by NXP for the ""three tables"" application. It is a good choice for the research and development of smart meters and portable handheld devices. MF RC522 utilizes advanced modulation and demodulation concepts and fully integrates all types of passive contactless communication methods and protocols at 13.56MHz. Support 14443A compatible transponder signals. The digital part handles ISO14443A frames and error detection. In addition, it also supports the fast CRYPTO1 encryption algorithm and verifies the MIFARE series of products. MFRC522 supports higher-speed contactless communication of MIFARE series, with bidirectional data transmission rate up to 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 te points and differences. The communication between it and the host adopts SPI mode, which is beneficial to reduce the connection, reduce the volume of the PCB board, and reduce the cost.

【Introduction to RFID Module】
The MF522-AN module uses Philips MFRC522 original chip to design the card reader circuit, which is easy to use and low in cost. It is suitable for users of advanced applications such as device development and card reader development, and users who need to design / produce RF card terminals. This module can be directly loaded into various card reader molds. The module adopts a voltage of 3.3V, and can be directly connected to any CPU motherboard of the user through a few lines of SPI interface, which can ensure the stable and reliable operation of the module and the distance of card readi
