The RC522 RFID card is a small size card with low power consumption that can read and write for labels operating at a frequency of 13.56 MHz, which is the NFC frequency.
It can be easily used with the combined multi microcontroller platform, especially Arduino. It has a communication speed of 424 kbit / s. RFID supports different types of encryption types. Supported card types are mifare1 S50, mifare1 S70 mifare ultralight, mifare pro and mifare desfire.
Not: It does not support RFID cards running at 125 KHz frequency. It only supports cards running at a frequency of 13.56 MHz. NFC modules can be used with NFC cards as they work with this frekans.
