MFRC522 is the highly integrated RFID card reader which works on non-contact 13.56 MHz communication, is designed with low power consumption, low cost and compact size read and write chip, is the best choice in the development of smart meters and portable hand-held devices. The module comes along with an RFID Card, RFID Tag and connector pins. It can
MF RC522 use the advanced modulation system, fully integrated at 13.56MHz with all kinds of positive non-contact communication protocols. MFRC522 support Mifare series higher speed non-contact communication, duplex communication speed up to 424 kb/s. As a new family member in 13.56MHz RFID family, MF RC522 has many similarities to MF RC5200 and MF RC530 and also has more new features.
This module can fit directly into handheld devices. The module uses a 3.3V power supply and can communicate directly with any CPU board by connecting through SPI protocol, which ensures reliable work, good reading distance.
