Hidden costs

Merchants pay a negotiated fee -- typically 1-3% for larger merchants and 3-6% for smaller merchants -- to process credit payments. They must also bear the cost of providing a point-of-sale solution to enable the acceptance of card transactions and other card services related expenses. Credit card issuers understand full well that if card holders were aware of and made to pay these additional costs with their purchases it would tend to discourage credit card usage. As a consequence, businesses who accept credit cards often must sign a "merchant agreement" or contract with the acquirer that stipulates that they are not allowed to offer different prices for card and non-card transactions (sometimes referred to as surcharging) despite the additional costs to the business for accepting the cards. The prohibition on surcharging or cash discounts is enforced by law in some countries, although some governments are beginning to lift this restriction (see below).[citations needed]
Some critics have observed that this results in what is effectively a hidden expense on all transactions conducted by merchants who accept credit cards since they must build the cost of transaction fees into their overall business expense. Furthermore, cash and other non-credit card using customers are in effect made to subsidize credit card user purchases. The cost of the convenience and protections enjoyed by card holders and the profits taken from transaction fees by the card industry (which has come to rely increasingly on this revenue stream over the years) is in part borne by the non-card purchaser. Critics further note that the customers most likely to pay in cash are probably the least able to afford the additional expense, the argument going that card holders are more likely to be affluent and non-card holders less so.[citations needed]
In response, others point out that credit cards can pay for themselves through an overall increase in sales, allowing the business owner to retain his existing price structure and offsetting the hidden extra expenses. Partly this is because accepting credit cards allows sales from customers who choose not to carry cash or a checkbook. Credit cards may also increase customer satisfaction and lead to more repeat sales due to their enhanced convenience, and time savings during the purchase process for both customers and employees decreases the realized cost.[citations needed]
One counterargument to the cash subsidization argument is that there are also costs to the merchant in other forms of payment. For cash payments these include frequent trips to the bank or use of an armored delivery service, theft, and employee error, such that cash is actually not cheaper for the merchant than credit cards. This argument may be specious, however, considering that many merchants would offer a discount for cash-paying customers were they allowed, and indeed, do so where it is legal. The fact that laws exist or have existed that prohibit such practices and that the major card issuers strongly discourage such practices can be taken as an indicator that cash transactions do not have as much cost associated with them as credit card transactions.[citations needed]
To illustrate, some companies offer incentives or bonus coupons for using cash, such as Canadian Tire Money. Australia is currently acting to reduce this by allowing merchants to apply surcharges for credit card users.
In the United Kingdom, merchants won the right through The Credit Cards (Price Discrimination) Order 1990[22] to charge customers different prices according to the payment method, but few merchants do so (the most notable exceptions being budget airlines, travel agents and UK government agencies, such as the DVLA). The United Kingdom is the world's most credit-card-intensive country, with 67 million credit cards for a population of 59 million people.[23]
In the United States, until 1984 federal law prohibited surcharges on card transactions. Although the federal Truth in Lending Act provisions that prohibited surcharges expired that year, a number of states have since enacted laws that continue to outlaw the practice; California, Colorado, Connecticut, Florida, Kansas, Massachusetts, Maine, New York, Oklahoma, and Texas have laws against surcharges. Regardless of what state one resides in or purchases a product, however, both Visa and MasterCard have publicly stated that surcharges on credit card transactions are against the rules. [24]
There also exists an economic argument that credit card use increases the "velocity" of money in an economy. The result, according to the quantity theory of money, is an effective increase in the money supply, as more money is flowing through the economy at a given time.
