Does that mean there is no challenge/response protocol in this system? Hard to believe - except that even more pissweak security mechanisms seem to be regularly attempted by people who should know better. I guess nothing happens until the proximity sensor changes from a selling feature to do-not-buy feature. It might be possible to develop signalling strategies that detect a repeater signal. It might also be possible to backrev a good old entry button (or an off switch) into the key. Paywave could also add a button or some contacts to enable the card response.
