Arduino + Processing

Hello. I've just posted a related question in the hardware interfacing section (see: RFID Noob), but figured that much of my trouble is software, so I wanted to post here as well.

I have an RFID reader wired and working, but I am unable to do much with the returned IDs. Ultimately I want to associate each ID with something more readable, and find a way to access that ID (or something more readable) from Processing.

The code I am using is closely related to this: http://www.arduino.cc/playground/Learning/PRFID

Any thoughts or suggestions would be greatly appreciated.

Thanks.

Just have a look up table with the IDs in it. Search the look up table for a match. Say you found it in the Nth entry. Then print out the matching Nth string in a string array. Or use the index of the entry in anything you want to trigger.
