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 size contactless read-write card chip for "three meters" application. It is a good choice for the research and development of intelligent instruments and portable handheld devices. MF rc522 fully integrates all kinds of passive non-contact communication modes and protocols at 13.56MHz by using advanced modulation and demodulation concepts. Support 14443a compatible transponder signal. The digital part processes iso14443a frame and error detection. In addition, it also supports fast crypto1 encryption algorithm to verify Mifare series products. Mfrc522 supports higher speed contactless communication of Mifare series, with bidirectional data transmission rate up to 424kbit / s. As a new member of 13.56MHz high integration read-write card family, MF rc522 has many similarities with MF RC500 and MF rc530, but also has many characteristics and differences. It uses SPI mode to communicate with the host computer, which is helpful to reduce the wiring, reduce the volume of PCB board and reduce the cost.

[introduction to RFID module]
Mf522-mini module uses rc522 chip to design card reading circuit. The module works at 13.56MHz frequency and meets iso14443a standard. It can support Mifare1 S50, Mifare1 S70, Mifare light, Mifare ultralight and Mifare pro. It is suitable for users of advanced applications such as device development and reader development, and users who need to design / produce RF card terminals. The module can be directly loaded into various reader molds. The voltage of the module is 3.3V, and it can directly communicate with any CPU motherboard of the user through a few simple lines of SPI interface, which can ensure the stable and reliable operation of the module and the long distance of card reading; The module has the characteristics of easy to use, high reliability and small size, which can help customers apply the contactless card to the system conveniently and quickly.
