Of course, credit cards have also opened online banking. There are several ways to open them:

First of all, you have to log in to the bank, personal online banking.

Then you have to log in the credit card you need to open under the credit card and credit card registration tab.

Then you have to click on the credit card > payment management > online payment management > under the label,

Finally, enter the card verification code and validity period according to the prompt, and select (turn on/off) the RMB online payment function of the credit card.
