Can I use a credit card when shopping in the supermarket?

You can use a credit card when shopping in a supermarket. As long as the supermarket supports credit card checkout, you can use a credit card. 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.

according to article 6 of the measures for the administration of bank cards, credit cards are divided into debit cards and quasi-credit cards according to whether or not the reserve fund is deposited with the issuing bank. Credit card refers to a credit card in which the issuing bank gives the cardholder a certain credit line, and the cardholder can spend first and then repay. Quasi-credit card refers to a credit card in which the cardholder must first deposit a certain amount of reserve fund according to the requirements of the issuing bank, and when the balance of the reserve fund account is insufficient to pay, it can be overdrawn within the credit limit stipulated by the issuing bank.

After the cardholder applies for opening the card service with exceeding credit limit, the card-issuing bank can only provide the card service with exceeding credit limit once in a billing cycle, and can only charge the over-limit fee once in a billing cycle.
