How long will it take for the bank card pre-authorization to arrive?

If you swipe your card at the domestic POS of China Merchants Bank Card for pre-authorization, you can swipe your card again at the settled POS when you leave the hotel, and immediately cancel the pre-authorization. If you leave the hotel without canceling the pre-authorization, and the hotel does not settle accounts with the bank after 30 days of pre-authorization, then our system will automatically cancel the pre-authorization transaction and the funds will be automatically returned to your account (no SMS will be sent). 2. If you need to return the funds relatively quickly, you must complete the "pre-authorization cancellation" transaction and the funds will be returned to your account at the same time. You can dial 95555 to enter the manual service and provide your card number, transaction date, amount, merchant name, merchant contact number, contact address and other information, and then the staff will follow up.
