Credit cards are divided into credit cards and quasi-credit cards. Credit card refers to the credit card issued by the bank, which gives the cardholder a certain credit limit, within which the cardholder can spend first and then repay. A quasi-credit card refers to a quasi-credit card issued by a bank. The cardholder deposits a certain amount of reserve fund according to the regulations. When the balance of the reserve fund account is insufficient to pay, it can be overdrawn within the prescribed credit limit. Credit cards generally refer to credit cards.
