How much does it cost a business to accept a debit card as payment?
It varies. Larger merchants have the best deals. Small ones the worst. About 30 cents per transaction and 2.5-3.25% of the dollar amount.
Exactly how much it costs big U.S. banks to process a Visa or MasterCard debit card transaction has long been murky – until the Federal Reserve surveyed the industry a few months ago and came up with a figure of 12 cents per swipe.
No charge at most US stores that have machines that take credit/debit.
