The RDM6300 RFID Reader is the type of RFID module with a 125 kHz frequency,

About Project:

The RDM6300 125 kHz EM4100 RFID Card ID Reader Module is specifically manufactured to read and write data from 125 kHz compatible tags. It can be utilized in surveillance systems for workplaces and residences, personal authentication, access management, digital toys as well as other output control systems.

RFID board utilizes an advanced RF receiver circuit and built-in MCU architecture, integrated with a high-efficiency decoding algorithm, to look through the EM4100 and all the compatible cards. Any microcontroller with UART serial peripheral can be utilized to operate with this RFID reader.

Then connect Arduino to the laptop and upload the code. Then just open the serial monitor at a baud rate of 9600 as well as scan the RFID tag on the Module’s Antenna. The respective tag number will be printed on the serial monitor.
