You can read RFID tags Using a RFID reader and an Arduino board. Below you can find the schematic for Connecting a RDM630serial RFID reader to an Arduino board.
Here is the sample code that reads RFID tags from RDM630 serial RFID reader and prints them on the serial port. You can see the results by clicking “Serial Monitor” in Arduino program. The LED blinks when the reader reads a tag.
