It's been my impression that the way you're supposed to verify the ID
of a credit card user is by checking the signature. I've heard of
banks telling businesses not to demand separate ID. On the other
hand, I can easily believe that Blockbuster came up with the ID idea
all by themselves.

I was in England last week where I noticed that the banks are
switching all UK credit cards to chip+pin technology. We'll see. For
that matter, French cards have all been chip+pin for years. Any idea
what their fraud rates are like? The French card machines will do
magstripe with a signature, but it's mostly us foreigners who need it.
