London Underground have a contactless system too, but it isn't used much. As
I remember it had a similar problem, but they may have changed that.

You take out your wallet with the card in and wave it over a palm-sized

withdraw a token. 

Muggers and pickpockets keep a close eye out to see how fat your wallet is
and where you keep it ...
