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 Special Features of 13.56MHZ RFID Reader Writer Module: it is a highly integrated analog circuitry to demodulate and decode responses. it Supports ISO/IEC14443A/MIFARE it is Typical operating distance in Reader/Writer mode for communication to an ISO/IEC14443A / MIFARE is 40~50 mm it Supports MIFARE Classic encryption in Reader/Writer mode it Supports ISO/IEC14443A higher transfer speed communication up to 848kbit/s it is controlled by serial UART interface its baud rate could be 2400 bps ~ 115200 EEPROM is preserved against cut off. it is easy to access by sending commands it has excellent EMC performance its size is 40mm x 50mm its power supply is 4.5V ~ 5.5V. it does not have a parity bit. it has 8 data bits. it has 1 stop bit. its Baud rate could be 2400bps ~ 115200bps
