What's the difference between online credit cards and traditional credit cards?

If you use an online credit card, you can only use it online.

In fact, online credit cards have no cards, only account numbers and passwords.

Usually a sub-account attached to a traditional credit card account.

The credit limit of online credit cards is generally low.

In order to avoid unnecessary losses of cardholders, some banks usually transfer the actual money of credit cards to online bank cards before spending, that is, how much they spend. For example, if they want to spend money in 500 yuan, they only transfer it to 500 yuan in the online bank card before spending money.
