RFID Card Reader/Detector Module Kit 13.56Mhz (RC522)
Item # 13071
13.56 Mhz RFID Reader-Writer Kit
Standard 3V MIFARE reader solution

MF RC522 is used in highly integrated 13.56MHz contactless communication card chip to read and write, of NXP for “three” and the application launched a low voltage, low cost, small size, non-contact card chip to read and write, intelligent instruments and portable handheld devices developed better. The MFRC522 reader supports ISO/IEC 14443 A/MIFARE mode.

The MFRC522’s internal transmitter is able to drive a reader/writer antenna designed to communicate with ISO/IEC 14443 A/MIFARE cards and transponders without additional active circuitry. The receiver module provides a robust and efficient implementation for demodulating and decoding signals from ISO/IEC 14443 A/MIFARE compatible cards and transponders. The digital module manages the complete ISO/IEC 14443 A framing and error detection (parity and CRC) functionality.
interface Protocol: Serial Peripheral Interface (SPI) up to 10 Mbit/s

As 13.56MHz highly integrated card reader series chip new family, the MF RC522 MF RC500 MF RC530 there are many similarities, but also have many of the characteristics and differences. Communication between it and the host SPI mode, helps to reduce the connection, reduce PCB board volume and reduce costs
