a credit card, also known as a debit card, is a credit certificate issued by a commercial bank or credit card company to a consumer with qualified credit. 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.

The credit card stipulated in the relevant laws of our country (Interpretation of the NPC Standing Committee on the Provisions on Credit Cards) refers to the electronic payment card issued by commercial banks or other financial institutions with all or some functions such as consumer payment, credit loan, transfer settlement, cash deposit and withdrawal. On December 1, 217, the Standard for English Translation and Writing in Public Service Field was officially implemented, stipulating that the English name of the CreditCard standard is Credit Card.
