Do RFID key cards track the user through entry ways?

At work we use RFID tags to enter the building and each floor. The tags double as photo ID, I always wondered if they are used (or can be used) to keep track of staff movements.

I always assumed that they were tied to a staff ID when issued. But another staff member thinks they are generic access i.e. all cards are copies (for each access level) and they just stick your picture on the front.

My question is: What is standard industry practice? I'm sure my scenario is technically feasible, but whether it is widely used is another question.
