Working Principle of RDM 6300 RFID Reader

The RDM 6300 works using radio frequency identification technology. When an EM4100 RFID card or tag is brought near the reader antenna, the module emits a 125KHz electromagnetic field.

The passive RFID tag absorbs energy from this field and responds by transmitting its unique identification number. The RDM6300 decodes this data and sends it through the serial UART interface to a microcontroller such as Arduino, ESP8266, or other embedded platforms.

The microcontroller can then compare the received ID with stored values to allow or deny access, log attendance, or trigger actions.
