UART RFID Reader Module 125kHz RDM6300 w/ Anthenna

RDM6300 125KHz 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 is the update version of RDM630, it has higher sensitivity and longer read range. The pins and output data is 100% compatible with old RDM630 module.

Features

• Support external antenna
• Maximum effective distance up to 50mm
• Less than 100ms decoding time
• UART interface
• Support EM4100 compatible read-only or read/write tags
• Small compact design

Package Included

• 1 x RDM6300 RFID module
• 1 x External antenna with connector

Connect RDM6300 to Arduino   (h-language)

#include <SoftwareSerial.h>
SoftwareSerial RFID(2 , 3); // RX=2 and TX=3

int i;

void setup()
{
  RFID.begin(9600);    // start serial to RFID reader
  Serial.begin(9600);  // start serial to PC 
}

void loop()
{
  if (RFID.available() > 0) 
  {
     i = RFID.read();
     Serial.print(i, DEC);
     Serial.print(" - ");
  }
}
