Credit Card

A credit card system is a type of retail transaction settlement and credit system, named after the small plastic card issued to users of the system. A credit card is different from a debit card in that the credit card issuer lends the consumer money rather than having the money removed from an account. It is also different from a charge card (though this name is sometimes used by the public to describe credit cards) in that charge cards require that the balance be paid in full each month. In contrast, a credit card allows the consumer to 'revolve' their balance, at the cost of having interest charged. Most credit cards are the same shape and size, as specified by the ISO 7810 standard.

A user is issued a credit card after an account has been approved by the credit provider (often a general bank, but sometimes a captive bank created to issue a particular brand of credit card, such as American Express Centurion Bank), with which they will be able to make purchases from merchants accepting that credit card up to a preestablished credit limit.

When a purchase is made, the credit card user agrees to pay the card issuer. Originally the user would indicate his/her consent to pay, by signing a receipt with a record of the card details and indicating the amount to be paid, but many merchants now accept verbal authorizations via telephone and electronic authorization using the Internet.

Electronic verification systems allow merchants (using a strip of magnetized material on the card holding information in a similar manner to magnetic tape or a floppy disk) to verify that the card is valid and the credit card customer has sufficient credit to cover the purchase in a few seconds, allowing the verification to happen at time of purchase. Other variations of verification systems are used by ecommerce merchants to determine if the user's account is valid and able to accept the charge.

Each month, the credit card user is sent a statement indicating the purchases undertaken with the card, and the total amount owed. The cardholder must then pay a minimum proportion of the bill by a due date, and may choose to pay the entire amount owed or more. The credit provider charges interest on the amount owed (typically at a much higher rate than most other forms of debt). Some financial institutions can arrange for automatic payments to be deducted from the user's accounts.

Credit card issuers usually waive interest charges if the balance is paid in full each month, but typically will charge full interest on the entire outstanding balance from the date of each purchase if the total balance is not paid.

For example, if a user had a $1,000. outstanding balance for purchases and pays the entire $1,000. there would be no interest charged. If, however, even $1.00 of the total balance remained unpaid, interest would be charged on the full $1,000 from the date of purchase until the payment is received. The precise manner in which interest is charged is usually detailed in a cardholder agreement which may be summarized on the back of the monthly statement.

The credit card may serve as a form of revolving credit, or the user may choose to apply any payments toward recent rather than previous debt. Interest rates can vary considerably from card to card, and the interest rate on a particular card may jump dramatically if the card user is late with a payment on that card or any other credit instrument. As the rates and terms vary, services have been set up allowing users to calculate savings available by switching cards, which can be considerable if there is a large outstanding balance (see external links for some on-line services).

Because profit margins in the credit card industry can be quite high, credit providers often offer incentives such as frequent flier miles, gift certificates, or cash back (typically 1 percent) to try to attract customers to their program.

Low interest credit cards or even 0% interest credit cards are available. The only downside to consumers is that the period of low interest credit cards is limited to a fixed term, usually between 6 and 12 months. However, services are available which alert credit card holders when their low interest period is due to expire. Most such services charge a monthly or annual fee.

Features

As well as convenient, accessible credit, the cards offer consumers an easy way to track expenses, which is necessary both for monitoring personal expenditures and the tracking of work-related expenses for taxation and reimbursement purposes. They have now spread worldwide, and are offered in a huge variety of permutations with differing credit limits, repayment arrangements such as automatic payment from a personal bank account (some cards offer interest-free periods, while others do not but compensate with much lower interest rates), and other perks (such as rewards schemes in which points earned by purchasing goods with the card can be redeemed for further goods and services or credit card cashback).

Some countries such as the United States and the United Kingdom limit the amount for which a consumer can be held liable due to fraudulent transactions as a result of a consumer's credit card being lost or stolen.

Profits and losses

Credit card issuers (banks) cover their costs (including the interest costs for the money that is paid to merchants prior to the bank being paid by customers), and earn profits, by:

• Interchange fees. Interchange fees are charged by the merchant's acquirer to a card-accepting merchant as component of the so-called merchant discount fee. The merchant pays a merchant discount fee that is typically 2 to 3 percent (this is negotiated), which is why some merchants prefer cash, debit cards, or even checks. The majority of this fee, called the interchange fee, goes to the issuing bank, but parts of it go to the processing network, the card brand (American Express, Visa, MasterCard, etc.), and the merchant's acquirer. The interchange fee that applies to a particular merchant is a function of many variables including the type of merchant, the merchant's average ticket dollar amount, whether the cards are physically present, if the card's magnetic stripe is read or if the transaction is hand-keyed, 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 fifteen percent of total revenues.

• Charging interest on outstanding balances. Customers who do not pay in full the amount owed on their monthly statement (the "balance") by the due date (that is, at the end of the "grace period") owe interest ("finance charges"). These customers are known in the industry as "revolvers". Those who pay in full (pay the entire balance) do not. These customers are known in the industry as "transactors" or "deadbeats". Interest charges vary widely from card issuer to card issuer. Often, there are "teaser" rates in effect for initial periods of time (as low as zero percent for, say, six months), whereas rates for those with poor credit can be as much as 29.74 percent (annualized). In the U.S. rules governing interest rates are set at the state level; some banks have chosen to establish their credit card operations in states such as South Dakota that have less restrictive limits on interest rates. See Usury laws.

• Fees charged to customers. The major fees are for (1) late payments; (2) charges that result in exceeding the credit limit on the card (whether done deliberately or by mistake); (3) cash advances and convenience checks (often 3 percent of the amount); (4) transactions in a foreign currency (as much as 3 percent of the amount; a few financial institutions charge no fee for this); and (5) membership fees (annual or monthly), sometimes a percentage of the credit limit.

Credit card companies generally guarantee the merchant will be paid on legitimate transactions regardless of whether the consumer pays their credit card bill. However, credit card companies generally will not pay a merchant if the consumer challenges the legitimacy of the transaction and will fine merchants who have a large number of chargebacks.

In recent times, credit card portfolios have been very profitable for banks, largely due to the booming economy of the late nineties. However in the case of credit cards, such high returns go hand in hand with risk, since the business is essentially one of making unsecured (uncollateralized) loans, and thus dependent on borrowers not to default in large numbers.

In some areas, such as Ireland, governments profit from credit cards through the imposition of a stamp duty or credit card tax. This is usually done where a cheque tax previously existed. This tax is taken automatically from the account, just like a purchase, by the bank on behalf of the government annually. This tax - unlike its cheque counterpart - is payable in arrears so no refund is possible.
