The so-called \ "pre-authorization \" means that when the cardholder checks into the hotel, the hotel estimates the consumption amount in advance according to the number of days of stay and the hotel deposit, and requires you to swipe your credit card for \ "pre-authorization \", that is, pay the deposit. Hotel cashier swipes the card 1200 yuan. In fact, the money is still on your card, but it has not been paid to the hotel. It's just that the amount is frozen, and the POS slip is blank, not the proof of bank card deduction.

When you check out, the hotel will destroy the original blank pre-authorized POS sheet, and go through the "pre-authorized completion" procedure again according to your actual consumption situation. (Some banks call it \ \ "pre-authorization confirmation \ \").

In other words, hotels generally destroy pre-authorized POS sheets after check-out, and they will automatically become invalid if they are not destroyed for 30 days.

Even if the hotel is not damaged, you can check whether the bill is included in this 1700 yuan and go to the credit card center to cancel the payment.
