Issuers of credit cards make money from cardholder fees and from inter-
est paid on outstanding balances. Not all issuers charge fees. Even
those that do, make most of their money on the interest. They really
LIKE people who pay the minimum each month.
Issuers of charge cards make money from cardholder fees. Some charge
cards actually run at a loss for the company, particularly those that
are free. The primary purpose of such cards is to stimulate business.
Issuers of debit cards may make money on transaction fees. Not all
debit card transactions have fees. Most debit cards exist to stimulate
business for the bank and to offload tellers and back-room departments.
To date, third-party debit cards exist solely to stimulate business.
Providers of such cards make no direct money from their use.
Acquirers make money from transaction charges and discount fees. Unlike
the charges and fees mentioned above, these fees are paid by the ac-
cepter, not (directly) by the cardholder. (Technically, it is not le-
gal for the merchants to pass these charges directly to the consumer.
Some petroleum stations have gotten away with giving a discount for
cash, and it has survived court challenges so far.) Transaction charges
are typically in pennies per transaction, and are sensitive to the type
of communication used for the authorization. Discount fees are a per-
centage of the purchase price and are sensitive to volume and compli-
ance to rules. One way to encourage merchants to follow certain
procedures or to upgrade to new equipment is to offer a lower discount
fee.
Until fairly recently, the only motivation for accepters was to expand
their business by accepting cards. Reduction of fraud was enough rea-
son for many merchants to pay authorization fees, but in many cases, it
isn't worth the cost. (That is, it is cheaper to pay the fraud than to
prevent it.) Recently, electronic settlement has provided merchants
with an added benefit by reducing float on charged purchases. Merchants
can now get their accounts credited much faster than before, which
helps cash flow.
Companies that issue charge cards are real keen on float reduction. The
sooner they can bill you, the sooner they get their money. Credit card
companies are also interested in float reduction, since the sooner they
bill, the sooner they can start charging interest. Debit cards
typically involve little or no float.
Affinity cards usually pay a percentage of purchases to the affinity
organization. Although it may seem obvious to take this money from the
discount fee, this doesn't work since the issuer is not always the
acquirer. The money for this usually comes from the interest paid on
outstanding balances. Essentially, the bank is giving a share of its
profits to an organization in turn for the organization promoting use
of its credit card. The affinity organization is free to use its cut
any way it wishes. An airline will typically put it into the frequent
flyer program (and credit miles to your account). A college may put
the money into the general fund or into a scholarship fund. Lord only
knows what a sports team does with the money!
