A better idea?  How about only permitting contactless transactions only after a card
has been swiped through the machine first?   This means the user is "authorising" contactless 
purchases only on machines they "trust".  Such authorisation would only last a set period
of time.   This could be useful for places you make regular transactions, not ad hoc
usage anywhere.  I do not use credit cards at all, so I may be mislead.
