Seeedstudio RFID 125KHz module-UART software?

I am attempting to use a Seeedstudio 125KHz RFID reader to read my animal pit tags. They are small glass tags and have an 18 digit ID code. I was wondering if anyone has successfully done something similar and could help me out? I have tried to modify several codes I found online but none seem to work for me.

this is the code I have been using:

int data1 = 0; void setup() { Serial.begin(9600); } void loop() { if (Serial.available() > 0) { // read the incoming number on serial RX data1 =; // display incoming number Serial.println(data1, DEC); } }

thanks Don

I don't know if you can read the tags, however, I do now that your code will not work! The Tag is not one digit. Read this…
