Radio frequency Identification (RFID) is a wireless identification technology that uses radio waves to identify the presence of RFID tags. We need to bring the RFID tags near to the reader to read the unique identifier number associated with that RFID tag as it has a microchip with radio antenna mounted on a substrate which carries a unique 12-byte identifier. RFID Reader has a transceiver and antenna mounted on it to read the data of the RFID tag and transmit the same to the microcontroller or the PC. It can communicate with your PC with either RS232 or WEIGAND communication protocols. The form of communication is selected by SEL pin. If SEL pin is selected HIGH then form of communication is RS232 and if SEL pin is pulled LOW then form of communication is WEIGAND. Usually, the RS232 is selected because it’s popular so SEL pin is pulled HIGH. You can use RFID tags in auto Attendance system, Item Identification system, Automatic payment mechanism, medical tags etc.
