how to get hex code off of RFID Tag HELP

My group has purchased an id-20 RFID Reader. We have connected it to a BASIC STAMP 2 microcontroller (and the serial computer interface which comes along with it.) we have also downloaded this rfid code reader program http://www.settorezero.com/wordpress/so … id-reader/. however we do not know how to get the microcontroller to interface with the computer to get the tag codes. We do not have an arduino so many similary questions that i have seen do not apply to us. Does anyone know how to get the tags without the usb drive from sparkfun/ an arduino microcontroller. Unfortunately without the tag codes we cannot start our programming.

Thanks for any help!!
