Crime pays, but I wonder if they get 2% rebate?

Why is it that my credit card company has the ability to determine an odd credit card transaction triggering a phone call to me in which I verify their presumption.  Wouldn't it seem more logical when these oddities arise to prompt the cashier for two forms of ID?

Not that I am too worried about it since it will all just be washed away and passed on to the hard working honest people who pay for things with legitimate money.
