When I go somewhere and pay for something and use my Debit Card....they always ask Debit or Credit? Credit, they swipe it, I sign the paper and i go on. Debit, I put in my pin number then they give me my receit. What is the difference in running my card as Debit or Credit besides just having to type in my pin #? Does the transaction go to the Bank the same? Why not just run them all as credit so u do not have to put ur pin in?
