A credit card is a small plastic card issued to users as a system of
payment. It allows its holder to buy goods and services based on the
holder's promise to pay for these goods and services. The issuer of
the card creates a revolving account and 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.
The credit cards allow the consumers a continuing balance of debt, subject to interest being charged.
Credit cards are issued by a credit card issuer, such as a bank or credit union,
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 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 not present transaction (CNP).
