Credit card consumption in hotels, hotels or leasing companies is often settled through pre-authorization. Generally speaking, it means to pay a deposit. Uber first applies to the bank to freeze a certain amount, and then deducts the money according to the actual consumption amount after you take the bus. Now many taxi software is such a payment method. For example, the number one car I use, CCB's credit card is bound. At that time, the suggested payment method was "pre-authorization", and hotel reservation and car rental were all such pre-authorization methods.
