I would like to point out that the merchant pays most of these fees, not the consumer. The average american uses a credit card about 1.5 times a day. There is a very complex fee structure in Credit Cards, per transaction, a % of each transaction, monthly terminal fees and more. On the consumer side, there are monthly fees, signup fees, cashback bonuses, and the big one Interest Fees. (This is where banks make most of the money.)
