Credit card, also called debit card, is a credit certificate issued by commercial banks or credit card companies to qualified consumers. It is in the form of a card with the name, expiration date, number and cardholder's name printed on the front, and a magnetic stripe and signature strip on the back. Consumers with credit cards can go to special commercial service departments for shopping or spending, and then the bank will settle accounts with merchants and cardholders, and cardholders can overdraw within the prescribed limit.
