It is not uncommon to have an attendant posted at badge in locations. Such that... this wouldn't really be hard to put a stop to. And that is assuming you couldn't just spot it in the data.
As I said in other response, I have no doubt these things can and will get gamed. I don't like the seeming escalation that is implied by this, though. Why start down that slope, if we can avoid it? (Valid to argue that the start down that pat was the badge readers, I think. But at some point, the last step has to stop being justification for the next.)
