The EM18 RFID Reader Module is based on the EM18 RFID Reader Chip. The module can read the unique ID number from RFID Cards and Tags that operate on 125kHz. The read value is then sent as TTL output so that it can be easily read by a microcontroller like Arduino. It is popularly used in Attendance systems, smart access control, and other Card-based entry systems.
Each unit consists of an RFID reader module and an RFID Card. The Reader module can be powered by 5V and the output from it can be read from the Tx pin.
