NFC RFID RC-522 Proximity IC Card Read/Write Module, SPI

The NFC RFID RC-522 Proximity IC Card Read/Write Module, SPI is a highly integrated contactless IC card/tag read/write module ideal for use with Arduino, Raspberry Pi or any micro-controller supporting a SPI interface. It operates at 13.56MHz and a low 3.3V, and is easily controlled via its SPI bus connectors. The MFRC522 supports contactless communication and uses MIFARE higher transfer speeds up to 848 kBd in both directions. It comes in an is easy-to-use, low profile package and provides excellent quality at a budget price.This will suit any microcontroller with an SPI interface.Features Highly integrated analog circuitry to demodulate and decode responsesSupports ISO/IEC 14443 A/MIFARETypical operating distance in Read/Write mode up to 50 mmSupports MF1xxS20, MF1xxS70 and MF1xxS50 encryption in Read/Write modeSupports ISO/IEC 14443 A higher transfer speed communication up to 848 kBdSPI up to 10 Mbit/sFIFO buffer handles 64 byte send and receiveFlexible interrupt modesPower-down by software modeProgrammable timer2.5 V to 3.3 V power supplyCRC coprocessorInternal self-test
