What we tried for our experiment was simple: you turn in your RFID card at the end of the meeting, and it is randomly re-used for the next one, i.e., a new number is assigned each meeting. Unfortunately, we only got a relatively small fraction of RFID badges back, if I recall correctly, as people presumably forgot to turn them in.
