Generally, it is not necessary to open it specially. Just enter the credit card number in the blank column similar to the "card number" after the payment window appears, and then follow the prompts to enter the relevant information of yourself and the credit card, and bind the random password received by the mobile phone to complete the payment. Need to be reminded that some merchants do not support credit card payment. If you insist on using a credit card, you need to pay a handling fee, which will be listed when you pay.

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.
