The freezing deposit depends on the hotel's regulations, which generally range from a few hundred to a few thousand.

If the hotel cancels the freeze, the credit card will be unfrozen the next day; if not, you will need to wait 30 working days for it to be automatically unfrozen.

Credit card pre-authorization refers to a transaction in which the card issuer or its agency confirms the permission to freeze the amount before the special merchant debits the money. The pre-authorization will occupy the card's credit limit and will be canceled when the customer settles the pre-authorization. If the customer does not make settlement within 30 days of the pre-authorization, the pre-authorization will be cancelled.

Credit card pre-authorization means that the merchant freezes a portion of the cardholder's funds before consumption. After the consumption is completed, the cardholder signs, and the merchant can officially deduct this part of the funds. The reason for this is to ensure that the cardholder's credit card has enough money for current consumption.
