While I applaud the general thrust
of Kevin's post, I think it's wrong to see credit card fraud as the fault of careless people leaving their credit cards around. More than that, even if that was the case, I assume there's some point to the whole signature verification thing. But in any case I've been the victim of people using my cards a few times. I think once a new card was stolen from the mail. The rest of the times I think it was all online purchases and I have no idea how they got the information.
