1. When a pre-authorization transaction occurs, the cardholder can log in to the online bank of the issuing bank at any time to inquire about the pre-authorization of the credit card. Credit card pre-authorization refers to the transaction in which the card issuer or its agent confirms the permitted frozen amount before the deduction of the special merchant.

Second, you can also call the credit card center for pre-authorization. If the "pre-authorization" is not cancelled in time, the bank will automatically cancel the frozen quota after 30 to 45 days. It is worth noting that during this period, the frozen part of the "pre-authorization" fund amount cannot be used.

3. A bank employee explained that when the consumer makes a formal settlement of the "pre-authorization", the "pre-authorization" will be cancelled, and the funds frozen by the "pre-authorization" will automatically enter the cardholder's account and generally return to the account within 24 hours.

Fourth, the pre-authorization amount can be found on the credit card online, and generally it will not be displayed immediately. Banks have their own bookkeeping dates, which can be found as early as one day after pre-authorization, and 3 or 4 days later. If it is foreign pre-authorization, the time will be longer.
