1. Cancellation proactively: pre-authorization will be returned approximately 1-2 days later.

2. Automatic cancellation: If a certain amount of pre-authorization is swiped after entering the store, if the merchant does not pre-authorize the transaction when leaving the store, the transaction will be canceled (some hotels will save trouble by swiping the card again when leaving the store) ), then the pre-authorized amount can only wait for automatic cancellation (generally, the time period for automatic cancellation of pre-authorization is generally 30-45 days, and this part of the frozen amount will occupy the original limit of the credit card).

Legal basis: Article 3 of the "Measures for the Supervision and Administration of Credit Card Business of Commercial Banks"_Commercial banks operating credit card business shall protect the legitimate rights and interests of customers and the security of relevant information in accordance with the law.
