It's simple. You need to activate the online consumption function of your credit card. This requires the bank to open this function. You can consult the service hotline of the bank.

If banks have additional requirements for online consumption. For example, you need to purchase a digital certificate. You also need the corresponding purchase to ensure the security of online transactions.

Theoretically speaking. As long as the online consumption function is enabled, all credit cards or debit cards can be consumed online. This is the same as ATM withdrawal. But you need to go to the bank to activate this function.
