Introduction to RC522 chip:

MF RC522 is a highly integrated read and write card chip used in 13.56MHz non-contact communication. It is a low voltage, low-cost, and small size non-contact read and write card chip launched by for NXP company for the “three meters” application. It is a good choice for the development of intelligent instruments and portable handheld devices. MF RC522 utilizes advanced modulation and demodulation concepts, fully integrating all types of passive non-contact communication methods and protocols at 13.56MHz. Supports 14443A compatible transponder signals. The digital part handles ISO14443A frames and error detection. In addition, it also supports fast CRYPTO1 encryption algorithm and validates MIFARE series products. MFRC522 supports faster contactless communication in the MIFARE series, with a bidirectional data transmission rate of up to 424kbit/s. As a new member of the 13.56MHz high integration read-write card series chip family, MF RC522 shares many similarities with MF RC500 and MF RC530, as well as many characteristics and differences. It adopts SPI mode for communication with the host, which is conducive to reducing wiring, reducing PCB board volume, and reducing costs.

Introduction to RFID module:

The MF522-AN module adopts the MFRC522 original chip design card reading circuit, which is convenient to use and low in cost. It is suitable for users who need to design/produce RF card terminals in equipment development, card reader development, and other applications. This module can be directly loaded into various card reader molds. The module adopts a voltage of 3.3V and can directly communicate with any CPU motherboard of the user through a few simple lines of SPI interface, ensuring stable and reliable operation of the module and long card reading distance.
