Overseas pre-authorization is used to verify your credit card and does not constitute consumption.

You can understand it as verifying whether your credit card can be used normally. It is not an actual deduction, but a frozen limit. The limit will be automatically restored in 7-30 days and will not be entered into the bill.

Pre-authorization refers to the behavior of cardholders making purchases in hotels, hotels or rental companies. Consumption and settlement are not completed at the same time. Special units request authorization from the card issuer in advance through POS.
