    EM-18 RFID reader is one of the commonly used RFID readers to read 125 kHz tags. It provides both UART and Wiegand26 output formats. EM18 RFID development board has TTL output that can be interfaced with any 5V driven microcontroller including Arduino Uno. The onboard buzzer in the module acknowledges the card is read or card error. The onboard DC Jack accepts a 5v to 12V DC adapter. It can be directly interfaced with microcontrollers using UART and with PC using an RS232 converter.

    RFID (radio frequency identification) systems use data strings stored inside RFID tags or transponders) to uniquely identify people or objects when they are scanned by an RFID reader. Because passive tags require a strong RF field to operate, their effective range is limited to an area in close proximity to the RFID reader. Each RFID Card/tag contains a unique identifier that can be read by this RFID Reader Module and transmitted to the host via a simple serial interface.
