Some of the folks who commented on the experiment pointed out that it 
would be POSSIBLE (but not easy) to figure out that ID tag # 1234578
actually belongs to Ole Jacobsen. Given this knowledge, you could,
using your own RFID reader equipment, theoritically follow my 
movements (or maybe that's not the right term) in this building.
In order to prevent any such skimming/tracking, you can "hide" your
RFID card and only unhide it if/when you present yourself at the 
microphone or "sign" the e-bluesheet.
