RDM6300 125KHz EM4100 RFID Card Reader Module is designed for reading code from 125KHz card compatible read-only tags and read/write card. It can be applied in office/home security, personal identification, access control, anti-forgery, interactive toy and production control systems etc. RDM6300 Series non contact RFID module, use the advanced RF receiving circuit and embedded MCU design, combing with high efficient decoding algorithm, to finish the data receive of EM4100 and all the compatible cards. 

One of the coolest part of IoT project must be the identification technology, 125Khz RFID module UART is the most popular RFID module. By connecting this RFID module to Arduino or Raspberry Pi, you are able to build projects that can be used in office/home security, personal identification, access control, anti-forgery, interactive toy and production control systems etc.

This module is easy to use, serial port connect to arduino MCU after power up, when RFID card enter into card reading range, this module will send the card number to arduino by UART You can further connect relay arduino shield to your arduino in order to enable the simple door keeper controlling system.
