Product Description of RFID Writer Reader Module
RFID is non-contact object recognition technology. it can recognize automatically the target. we can get relevant data through rf signals. many interactive projects are made by it and need to use RFID to achieve object recognization. RFID module is based on MFRC522. it is a highly integrated reader or writer. it is contactless communication. frequency is 13.56MHz. it is contactless communication. which is using MIFARE high transfer speeds up to 848 kbit in both directions. MCU is embedded in this module. we can be sending a command via the interface and the can use it. the operation of RFID is very easy. Embedded MCU has done many works. RFID module is an SPI interface on the board.
there are various host interfaces on this module:
it has an SPI interface.
it has Serial UART
