A credit card is a payment card, usually issued by a bank, allowing its users to purchase goods or services, or withdraw cash, on credit. Using the card thus accrues debt that has to be repaid later. Credit cards are one of the most widely used forms of payment across the world.
A regular credit card is different from a charge card, which requires the balance to be repaid in full each month, or at the end of each statement cycle. In contrast, credit cards allow consumers to build a continuing balance of debt, subject to interest being charged at a specific rate. A credit card also differs from a charge card in that a credit card typically involves a third-party entity that pays the seller, and is reimbursed by the buyer, whereas a charge card simply defers payment by the buyer until a later date. A credit card also differs from a debit card, which can be used like currency by the owner of the card.
As of June 2018, there were 7.753 billion credit cards in the world. In 2020, there were 1.09 billion credit cards in circulation in the United States, and 72.5% of adults (187.3 million) in the country had at least one credit card.
