> I mean with the amount of stolen card details routinely traded and used successfully (at least for a while) and with how little crime like that is investigated or punished in some jurisdictions, I dunno...

There's a huge difference between me using your credit card to buy stuff off Amazon (chance of success: somewhere between "doubtful" and "near-definite" depending mostly on geographical factors and your particular bank), and me walking around with a hacked card reader and stealing money out of your account by dialing in phony transactions directed to my account (chance of success: somewhere between "zero" and "also zero, but with a decimal point followed by more zeroes").
