I've never actually found a machine to try my card out upon. But the 
Oyster pads in London require the card to be pretty much out of a wallet 
and touching the surface. Similarly the RFID cards used on the buses in 
Nottingham. The technology is dozens of order of magnitude away from 
scanning the bus pass in the passenger's pocket as he gets on board.
