I am also wondering as to what a big problem this is...stolen cards being used at gas stations. Boy, I just grabbed a guy's wallet...let's run and gas up rather than use the card to stock up at Walmart. And, if the card hasn't been reported stolen, the merchant's liability is nil so long as it was inserted and the magnetic strip read and an approval was generated, not just inputted by hand as on a website...But, in the eyes of the bean-counters, better that someone gets robbed and injured than even $30 be diverted from the CEO's coke and hooker fund.
