MFRC-522 RC522 RFID RF IC Card Sensor Module Send S50 Fudan Card RF Module keychain For Arduino

Introduction of RC522 chip：

MF RC522 is applied to 13.56MHz contactless communication high integrated card reader chip is "three table" Application of the launch of a low voltage, low cost, small volume of the contactless card chip reader, intelligent instrument and portable handheld devices is a better choice for the development of. MF RC522 takes advantage of the advanced modulation and demodulation concepts, and fully integrates all types of passive contactless communications and protocols under the 13.56MHz. Supports 14443A compatible transponder signals. The digital part deals with ISO14443A frames and error detection. In addition, we also support fast CRYPTO1 encryption algorithm, which is used to validate MIFARE products. MFRC522 supports the MIFARE series of more high-speed contactless communications, bidirectional data transmission rate of up to 424kbit/s. As a new member of the 13.56MHz high integration reader and card family, there are many similarities between MF RC522 and MF RC500 and MF RC530, but they also have many characteristics and differences. It uses the SPI mode to communicate with the host computer, which is beneficial to reduce the connection, reduce the volume of the PCB board and reduce the cost.
