Characteristics
Mini-Module RDM6300 125KHz card is designed for code reading 125 kHz / 134.2 kHz read only card compatible tags and read / write card. It can be applied in office / home security, personal identification, access control, anti-forgery, interactive toy and Etc. production control systems

RDM6300 series RFID contactless module, use the advanced RF receiving circuitry and embedded MCU, Combing design with high efficient decoding algorithm, to finish the Receive Data EM4100 and all compatible cards. This is a very popular RFID Card Read module for Arduino users, It can read 125K EM4100 Series RFID Card.

This module is easy to use serial port to connect to Arduino MCU after power, when RFID card enter card read range, this module will send the card number to Arduino by UART You can also connect Arduino Shield relay for its Arduino in order to enable simple Keeper door control system.
