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 list, and go through the "pre-authorized completion" procedure according to your actual consumption situation to check out again. Some banks call it "pre-authorization confirmation".
"Pre-authorization Confirmation" is a new list issued by the hotel. The hotel will let you swipe your card before signing. After deducting the actual consumption amount from the pre-authorized amount, the remaining frozen funds will be unfrozen. At this time, the amount of the credit card is the real fee paid to the hotel.
