RDM3600 RFID COMPONENT

These issues are often causes by the simple things.

Have you tried swapping the TX/RX pins around?

Can you take a photo or sketch out your connections between the RFID reader and the Arduino.

Here is a picture. Just power, ground, and a jumper to pin 3 on the Arduino Uno and the antenna that came with the RDM3600. I modified the code to change the RX and TX pins to 3 and 4:

#include <SoftwareSerial.h>

SoftwareSerial RFID(3, 4);

int i;

void setup()

{

  RFID.begin(9600);

  Serial.begin(9600);

  Serial.println("ready");

}

void loop()

{

  if (RFID.available() > 0)

  {

    i=RFID.read();

    Serial.print(i, DEC);

    Serial.println(" next");

     }

  }

I have switched the Rx and Tx pins, in addition to adding the LED function changing digital input pins on the Arduino Uno. I have also bought another RDM6300 board and tried a different Arduino board. Nothing seems to work.

Looking at your wiring it seems you are putting your power pins in a different place to that shown on the guide you linked to.

I was using a WMATA SmartTrip card and some tags I found on Amazon:

I chose the RDM3600 because I can modify the antenna to increase the read range.

Are you trying to use Mifare tags? If so they operate on 13.56MHz.

I've just purchased one of these modules, so I should have a better idea whats going on in a couple of days.

I think my problem is I'm using RFID tags that operate at a higher frequency than the 125kHz that the reader uses.

I ordered some new tags, I will keep you posted.
