A debit card should work just like a credit card. Debit cards use to have a big advantage of just punching in your pin while with a credit, you had to wait for the receipt to print out then sign it. I think most large retailers let you sign it on a touchpad. I prefer the credit card, so I can be lazy and make payments at the end of the month. Probably not the best method, but I do have the money in my bank account (for payments) so I'm not entirely worried.
