I believe so
Barclays are now rolling these cards out in the UK and no doubt other banks will follow.
Also in London "everyone" is using the Oyster card - again details can be picked up by a scanner
And when you have your passport in your pocket at an airport - perfect way for the scoundrels to know your house is empty!
Call me anal /old fashioned but I will not even approve any of my bank details / accounts to be available over the internet - I do not consider it secure! - I'll take the time to visit a branch if need be.
