Interchange fee

Bank card associations like Visa and MasterCard require merchants to pay billions of dollars in Interchange fees to banks that issue their credit and debit cards.[18] Card-issuing banks obtain these interchange fees in addition to the enormous revenue they receive from cardholder interest and fees. Interchange fees are the single largest component of the various fees that banks deduct from merchants' credit card sales. Merchants pay their banks fees of 1 to 6 percent of each sale (for large merchants these fees may be negotiated, but will vary not only from merchant to merchant, but also from card to card, with business cards and rewards cards generally costing the merchants more to process), which is why many merchants prefer cash, PIN-based debit cards, or even cheques. Traditionally, interchange fees have been set by the bank card associations and their major card-issuing banks, who are the primary beneficiaries of these fees.

The interchange fee that applies to a particular merchant is a function of many variables including the type of merchant, the merchant's total card sales volume, the merchant's average transaction amount, whether the cards are physically present, if the card's magnetic stripe is read or if the transaction is hand-keyed or entered on a website, the specific type of card, when the transaction is settled, the authorized and settled transaction amounts, etc. For a typical credit card issuer, interchange fee revenues may represent about a quarter of total revenues, but this will vary greatly among credit card issuers. Interchange fees may consume over 50 percent of profits from card sales for some merchants (such as supermarkets) that operate on slim margins. Merchants contend that interchange fees force them to raise prices for everyone; banks contend that interchange fees enable them to offer better cardholder rewards for their best customers.
