Pre-authorization is to complete the deduction. There will be a document after pre-authorization, depending on whether the transaction type on the document is "Pre-authorization Complete" or "Pre-authorization Confirmation". If so, the user's account will return to normal the next day at most. In one case, the consumption directly paid by the hotel to consumers is part of the deposit, and the pre-authorization has not been revoked. It takes a relatively long time to unfreeze the pre-authorization cancellation, which varies according to different banks.

Precautions for pre-authorization of credit cards are as follows:

A, carefully check the pos machine to sign the bill.

When swiping a card for pre-authorization, you should carefully check the receipt issued by the pos machine. If the card is pre-authorized, it will be clearly marked in the column of transaction type, and then signed after confirmation.

Second, open the SMS notification function.

It is suggested that cardholders must open the credit card SMS notification function to keep abreast of their consumption at a glance. In the process of use, if there is any problem, contact the issuing bank in time.

Third, take the initiative to confirm after the credit card transaction is completed.

After the check-out and rent withdrawal procedures are completed, the cardholder should also consciously ask or confirm the relevant merchants to immediately revoke the pre-authorization, restore the quota, and eliminate possible risks and losses.

Four, the revocation should be carried out in a timely manner, and keep the certificate.

If you intend to cancel the reservation, you should ask the hotel or agency to go through the pre-authorization cancellation procedures within the prescribed time limit, and ask for the cancellation number as the cancellation certificate. Because after using pre-authorization, if it is not cancelled in time, merchants can directly draw the money away, and banks generally will not refuse to pay.
