Er.... it depends on which type of RFID reader you are using. Generally there are 2 types of RFID reader, the famous one uses Weigand format, and some uses UART/RS232.
If Weigand, not much help can be given.
If UART/RS232, basically is just sending the tag ID. Mostly is ASCII. I have never uses Proteus before, but if it allow you to input ASCII code or value into RX pin of PIC, you should be able to do it.
