A card issued by a financial company giving the holder an option to borrow funds, usually at point of sale. Credit cards charge interest and are primarily used for short-term financing. Interest usually begins one month after a purchase is made and borrowing limits are pre-set according to the individual's credit rating.
Credit card is a device used to obtain consumer credit at the time of purchasing an article or service. Credit cards may be issued by a business, such as a department store or an oil company, to make it easier for consumers to buy their products. Alternatively credit cards may be issued by third parties, such as a bank or a financial services company, and used by consumers to purchase goods and services from other companies.
There are two types of cards : credit cards and charge cards. Credit cards such as Visa and MasterCard allow the consumer to pay a monthly minimum on their purchases with an interest charge on the unpaid balance. Charge cards, such as American Express, require the consumer to pay for all purchases at the end of the billing period.
The growth of credit cards has had an enormous impact on the economy ; changing buying habits by making it much easier for consumers to finance purchases and by lowering savings rates (because consumers do not need to save money for larger purchases). Oil companies, car makers, and retailers have also used the cards to market their goods and services, using credit as a way of encouraging consumers to buy. Concern has been voiced over widespread distribution of bank credit cards to consumers who may not be able to pay their bills; costly losses and theft of cards; inaccurate (and damaging) credit records; high interest rates on unpaid balances; and excessive encouragement of consumer debt that has cut savings in the United States.

Credit card fraud is a wide-ranging term for theft and fraud committed using a credit card or any similar payment mechanism as a fraudulent source of funds in a transaction. The purpose may be to obtain goods without paying, or to obtain unauthorized funds from an account. Credit card fraud is also an adjunct to identity theft. According to the Federal Trade Commission, while identity theft had been holding steady for the last few years, it saw a 21 percent increase in 2008. However, credit card fraud, that crime which most people associate with ID theft, decreased as a percentage of all ID theft complaints for the sixth year in a row.
