Introduction - If you have any usage issues, please Google them yourself
MF RC522 supports all layers of ISO/IEC14443A/B and the classic MIFARE protocol, as well as standards compatible with this standard. Supports high-speed MIFARE, contactless communications, baud rates. The internal transmitter does not need to add an active circuit to directly drive an antenna near the operating distance (up to 100mm). The receiver section provides a robust and efficient demodulation and decoding circuit for ISO14443A compatible transponder signals. The digital part of ISO14443A frames and error detection (parity CRC). In addition, it supports fast CRYPTO1 encryption algorithms for validating MIFARE products. The host communication mode has 8 bit parallel and SPI mode, and the user can select different modes according to different requirements, which provides great flexibility for the design of the reader / terminal.
