Before using credit card for online payment, the online payment function must be enabled in advance. If you have more than one credit card in your name, each credit card needs to have an online payment function separately. Online payment function is not needed for professional payment, fast payment and online payment of overseas websites.
Access: Log in to credit card online banking and click "Online Payment" → "Online Payment Function Application".
You can also turn on your mobile phone: log in to the credit card mobile banking and enter "online payment" → "online payment function application".
