RC522 SPI 13.56MHz RFID Reader/Writer Soldered:With Soldered Pin Arduino compatible interfaceRC522 is a highly integrated RFID card reader which works on non contact 13. 56MHz communication. Designed by NXP, as a low power consumption, low cost and compact size read and write chip, it is the best choice in the development of smart meters and portable hand held devices. NFC (Near Field Communications) is a way for two devices very close to each other to communicate. Sort of like a very short range bluetooth that doesn't require authentication.
