the idea is old as dirt, and some millions of people had it before you. credit card swipes cost you between 2.4 and 4.5%, depending on the cards, the provider, and the amounts, plus potentially a fixed small amount per swipe. of course, a 2% cash back card cost more than 2% to swipe; and a 3% cash back card cost more than 3% to swipe; those guys are not morons.
