Parallax RFID 28340 card

I currently have an RFID 28340 card. I am looking for how to program an arduino one. I have the USB host shield but I don't know how to program the arduino to read the tags. Maybe they have some basic program to start?

Google on Parallax RFID 28340 gives this: RFID Card Reader - USB - Parallax

Thank you for responding, I already visited this page but they don't have information about programming this board in Arduino
