Please use CCB credit card for pre-authorization transaction. Can you receive the SMS notification?

The credit card pre-authorization transaction you mentioned in your question generally refers to the credit card transaction when you book a hotel room (that is, freezing a certain amount). This is a reservation service that allows hotels to reserve rooms for you. When you make pre-authorization transaction, you will receive SMS notification.

However, when you complete this authorization, your actual settlement amount is within a certain range of the previous pre-authorization amount, and you will not receive formal SMS notification. The scope of domestic transactions and overseas transactions is different:

Overseas transactions-115%; Domestic transactions-102%.
