RFID module RC522+2 tags (keychain and card)

Features :

RC522 chip
MF RC522 is applied to the highly integrated read and write 13.56MHz contactlesscommunication card chip, launched by the company for the "table" application of a low-voltage, low-cost, small size of the non-contact card chip to read and write, smart metersand portable handheld devices developed better choice. The MF RC522 use of advancedmodulation and demodulation concept completely integrated in all types of 13.56MHz passivecontactless communication methods and protocols. 14443A compatible transponder signals.
The digital part of to handle the ISO14443A frames and error detection. In addition,fast support CRYPTO1 encryption algorithm, terminology validation For products. MFRC522support For series of high-speed non-contact communication, two-way data transmission rateup to 424kbit/s. As new members of the 13.56MHz reader card series of highly integratedchip family, MF RC522 MF RC500 MF RC530 There are a lot of similarities, but also havemany of the characteristics and differences. Communication between it and the host SPImode helps to reduce the connection narrow PCB board volume, reduce costs.

RFID module
The MF522-AN module the the original MFRC522 chip design circuit card reader, easy to use,
low cost, and applies to the user equipment development, the reader and the development ofadvanced applications, the need for the user RF card terminal design/production. Thismodules can be directly loaded into the various reader molds. Utilizes a voltage of 3.3V, through the SPI interface simple few lines directly with any user CPU motherboard  connected communication can ensure that the module is stable and reliable work, distancecard reader;
