Proximity Security System (Keyless Entry)
Posted December 9, 2012 by Chris
“For our final project, we designed and built an RFID-based proximity security system for use with Cornell Identification cards, which have been RFID-embedded since fall of 2003. The idea for this project was sort of spawned from our general interest in RFID technologies and the near-simultaneous occurance of Lab 2 and the antiquated lock system at our fraternity house breaking.”

I doubt the actual student ID is encoded on the card, that will be abstracted back in the campus-wide security management system.
The unique card-ID is assigned to the student ID when issued, and used as normally with the look-up performed to confirm the card ID being ‘valid’ in contenxt of the lock being accessed.
If the card is lost or damaged the student requests a new card – the old one is deleted/invalidated, and a new card issued – with the new card number associated with the same student ID… and yes you may be able to assign multiple cards under a single student ID – but that’s a function of the campus-wide security control system.
Cheers

…of course…
You could spoof multiple cards having the same ‘card number’ – which will have student ‘X’ appearing all over the campus simultaneously!
