Interchange fees are supposedly charged by Visa and MasterCard in order to cover the cost of processing a credit or debit card transaction. These fees continue to rise even though processing costs have decreased. Nearly $50 billion in interchange fees were charged by credit and debit card networks in 2008 — coming out of the bottom lines of small businesses, charities and government balance sheets. Of these fees, 80 percent of these fees went to just ten large banks.
