Credit card


This article is about the payment system. For The Price Is Right game, see Credit Card (pricing game).
A credit card is part of a system of payments named after the small plastic card issued to users of the system. The issuer of the card grants a line of credit to the consumer (or the user) from which the user can borrow money for payment to a merchant or as a cash advance to the user. A credit card is different from a charge card, where a charge card requires the balance to be paid in full each month. In contrast, credit cards allow the consumers to 'revolve' their balance, at the cost of having interest charged. Most credit cards are issued by local banks or credit unions, and are the same shape and size, as specified by the ISO 7810 standard

How credit cards work

Credit cards are issued after an account has been approved by the credit provider, after which cardholders can use it to make purchases at merchants accepting that card.

When a purchase is made, the credit card user agrees to pay the card issuer. The cardholder indicates his/her consent to pay, by signing a receipt with a record of the card details and indicating the amount to be paid or by entering a Personal identification number (PIN). Also, many merchants now accept verbal authorizations via telephone and electronic authorization using the Internet, known as a 'Card/Cardholder Not Present' (CNP) transaction.

Electronic verification systems allow merchants 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. The verification is performed using a credit card payment terminal or Point of Sale (POS) system with a communications link to the merchant's acquiring bank. Data from the card is obtained from a magnetic stripe or chip on the card; the latter system is in the United Kingdom and Ireland commonly known as Chip and PIN, but is more technically an EMV card.

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. These will typically involve the cardholder providing additional information, such as the security code printed on the back of the card, or the address of the cardholder.

Each month, the credit card user is sent a statement indicating the purchases undertaken with the card, any outstanding fees, and the total amount owed. After receiving the statement, the cardholder may dispute any charges that he or she thinks are incorrect (see Fair Credit Billing Act for details of the US regulations). Otherwise, the cardholder must pay a defined minimum proportion of the bill by a due date, or may choose to pay a higher amount up to the entire amount owed. The credit provider charges interest on the amount owed if the balance is not paid in full (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 bank accounts, thus avoiding late payment altogether as long as the cardholder has sufficient funds.

Canada
The Government of Canada maintains a database of the fees, features, interest rates and reward programs of nearly 200 credit cards available in Canada. This database is updated on a quarterly basis with information supplied by the credit card issuing companies. Information in the database is published every quarter on the website of the Financial Consumer Agency of Canada (FCAC).

Information in the database is published in two formats. It is available in PDF comparison tables that break down the information according to type of credit card, allowing the reader to compare the features of, for example, all the student credit cards in the database.

The database also feeds into an interactive tool on the FCAC website.[24] The interactive tool uses several interview-type questions to build a profile of the user's credit card usage habits and needs, eliminating unsuitable choices based on the profile, so that the user is presented with a small number of credit cards and the ability to carry out detailed comparisons of features, reward programs, interest rates, etc.

History

The concept of using a card for purchases was described in 1887 by Edward Bellamy in his utopian novel Looking Backward. Bellamy used the term credit card eleven times in this novel.[25]

The modern credit card was the successor of a variety of merchant credit schemes. It was first used in the 1920s, in the United States, specifically to sell fuel to a growing number of automobile owners. In 1938 several companies started to accept each other's cards. Western Union had begun issuing charge cards to its frequent customers in 1914.[citation needed] Some charge cards were printed on paper card stock, but were easily counterfeited.

The Charga-Plate was an early predecessor to the credit card and used during the 1930s and late 1940s. It was a 2 1/2" x 1 1/4" rectangle of sheet metal, similar to a military dog tag, that was embossed with the customer's name, city and state (no address). It held a small paper card for a signature. It was laid in the imprinter first, then a charge slip on top of it, onto which an inked ribbon was pressed.[26] Charga-Plate was a trademark of Farrington Manufacturing Co. Charga-Plates were issued by large-scale merchants to their regular customers, much like department store credit cards of today. In some cases, the plates were kept in the issuing store rather than held by customers. When an authorized user made a purchase, a clerk retrieved the plate from the store's files and then processed the purchase. Charga-Plates speeded back-office bookkeeping that was done manually in paper ledgers in each store, before computers.

The concept of paying different merchants using the same card was invented in 1950 by Ralph Schneider and Frank X. McNamara, founders of Diners Club, to consolidate multiple cards. The Diners Club, which was created partially through a merger with Dine and Sign, produced the first "general purpose" charge card, and required the entire bill to be paid with each statement. That was followed by Carte Blanche and in 1958 by American Express which created a worldwide credit card network.

Bank of America created the BankAmericard in 1958, a product which, with its overseas affiliates, eventually evolved into the Visa system. MasterCard came to being in 1966 when a group of credit-issuing banks established MasterCharge; it received a significant boost when Citibank merged its proprietary Everything Card, launched in 1967, into Master Charge in 1969. The fractured nature of the U.S. banking system meant that credit cards became an effective way for those who were traveling around the country to move their credit to places where they could not directly use their banking facilities. In 1966 Barclaycard in the UK launched the first credit card outside of the U.S.

There are now countless variations on the basic concept of revolving credit for individuals (as issued by banks and honored by a network of financial institutions), including organization-branded credit cards, corporate-user credit cards, store cards and so on.

In contrast, although having reached very high adoption levels in the US, Canada and the UK, it is important to note that many cultures were much more cash-oriented in the latter half of the twentieth century, or had developed alternative forms of cash-less payments, such as Carte bleue or the Eurocard (Germany, France, Switzerland, and others). In these places, the take-up of credit cards was initially much slower. It took until the 1990s to reach anything like the percentage market-penetration levels achieved in the US, Canada, or the UK. In many countries acceptance still remains poor as the use of a credit card system depends on the banking system being perceived as reliable.

In contrast, because of the legislative framework surrounding banking system overdrafts, some countries, France in particular, were much faster to develop and adopt chip-based credit cards which are now seen as major anti-fraud credit devices.

The design of the credit card itself has become a major selling point in recent years. The value of the card to the issuer is often related to the customer's usage of the card, or to the customer's financial worth. This has led to the rise of Co-Brand and Affinity cards - where the card design is related to the "affinity" (a university, for example) leading to higher card usage. In most cases a percentage of the value of the card is returned to the affinity group.

Collectible credit cards

A growing field of numismatics (study of money), or more specifically exonumia (study of money-like objects), credit card collectors seek to collect various embodiments of credit from the now familiar plastic cards to older paper merchant cards, and even metal tokens that were accepted as merchant credit cards. Early credit cards were made of celluloid plastic, then metal and fiber, then paper, and are now mostly plastic.

Hidden costs

In the United Kingdom, merchants won the right through The Credit Cards (Price Discrimination) Order 1990[30] to charge customers different prices according to the payment method. The United Kingdom is the world's most credit-card-intensive country, with 67 million credit cards for a population of 59 million people.[31]

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.

Controversy

Credit card debt has soared, particularly among young people. Since the late 1990s, lawmakers, consumer advocacy groups, college officials and other higher education affiliates have become increasingly concerned about the rising use of credit cards among college students. The major credit card companies have been accused of targeting a younger audience, in particular college students, many of whom are already in debt with college tuition fees and college loans and who typically are less experienced at managing their own finances.

A 2006 documentary film titled Maxed Out: Hard Times, Easy Credit and the Era of Predatory Lenders deals with this subject in detail.[27] The nonprofit group Americans for Fairness in Lending works with Maxed Out to educate Americans about credit card abuse.

Another controversial area is the universal default feature of many North American credit card contracts. When a cardholder is late paying a particular credit card issuer, that card's interest rate can be raised, often considerably. With universal default, a customer's other credit cards, for which the customer may be current on payments, may also have their rates and/or credit limit changed. This universal default feature allows creditors to periodically check cardholders' credit portfolios to view trade, allowing these other institutions to decrease the credit limit and/or increase rates on cardholders who may be late with another credit card issuer. Being late on one credit card will potentially affect all the cardholder's credit cards. Citibank voluntarily stopped this practice in March 2007 and Chase stopped the practice in November 2007.[28] The fact that credit card companies can change the interest rate on debts that were incurred when a different rate of interest was in place is similar to adjustable rate mortgages where terms of a contract are changed after the contract has been formed (i.e. after the transaction is completed and the debt incurred).

Another controversial area is the trailing interest issue. Trailing interest is the practice of charging interest on the entire bill no matter what percentage of it is paid. U.S Senator Carl Levin raised the issue at a U.S Senate Hearing of millions of Americans whom he said are slaves to hidden fees, compounding interest and cryptic terms. Their woes were heard in a Senate Permanent Subcommittee on Investigations hearing which was chaired by Senator Levin who said that he intends to keep the spotlight on credit card companies and that legislative action may be necessary to purge the industry.[29]

In the United States, some have called for Congress to enact additional regulations on the industry; to expand the disclosure box clearly disclosing rate hikes, use plain language, incorporate balance payoff disclosures, and also to outlaw universal default. At a congress hearing around March 1, 2007, Citibank announced it would no longer practice this, effective immediately. Opponents of such regulation argue that customers must become more proactive and self-responsible in evaluating and negotiating terms with credit offerers. Some of the nation's influential top credit card issuers, who are among the top fifty corporate contributors to political campaigns, successfully opposed it.

Credit card numbering

Main article: Credit card number

The numbers found on credit cards have a certain amount of internal structure, and share a common numbering scheme.

The card number's prefix, called the Bank Identification Number, is the sequence of digits at the beginning of the number that determine the bank to which a credit card number belongs. This is the first six digits for MasterCard and Visa cards. The next nine digits are the individual account number, and the final digit is a validity check code.

In addition to the main credit card number, credit cards also carry issue and expiration dates (given to the nearest month), as well as extra codes such as issue numbers and security codes. Not all credit cards have the same sets of extra codes nor do they use the same number of digits

Redlining

Credit Card redlining is a spatially discriminatory practice among credit card issuers of providing different amounts of credit to different areas, based on their ethnic-minority composition, rather than on economic criteria, such as the potential profitability of operating in those areas.[

Credit cards as funding for entrepreneurs

Credit cards are a creative, yet often risky way for entrepreneurs to acquire capital for their start ups when more conventional financing is unavailable. It is rumoured that Larry Page and Sergey Brin's start up of Google was financed by credit cards to buy the necessary computers and office equipment, more specifically "a terabyte of hard disks".[33] Similarly, filmmaker Robert Townsend financed part of Hollywood Shuffle using credit cards.[34] Director Kevin Smith funded Clerks in part by maxing out several credit cards. Actor Richard Hatch also financed his production of Battlestar Galactica: The Second Coming partly through his credit cards. Famed hedge fund manager Bruce Kovner began his career (and, later on, his firm Caxton Associates) in financial markets by borrowing from his credit card.


Credit cards in ATMs

Many credit cards can also be used in an ATM to withdraw money against the credit limit extended to the card, but many card issuers charge interest on cash advances before they do so on purchases. The interest on cash advances is commonly charged from the date the withdrawal is made, rather than the monthly billing date. Many card issuers levy a commission for cash withdrawals, even if the ATM belongs to the same bank as the card issuer. Merchants do not offer cashback on credit card transactions because they would pay a percentage commission of the additional cash amount to their bank or merchant services provider, thereby making it uneconomical.

Many credit card companies will also, when applying payments to a card, do so at the end of a billing cycle, and apply those payments to everything before cash advances. For this reason, many consumers have large cash balances, which have no grace period and incur interest at a rate that is (usually) higher than the purchase rate, and will carry those balance for years, even if they pay off their statement balance each month
