Credit card pre-authorization is equivalent to paying a deposit for consumption, but it is more convenient than paying a deposit because the cardholder does not have to actually come up with money. Compared with cash and debit cards, the advantages are very obvious.

Take a hotel as an example. The cardholder swipes the card at the hotel front desk for pre-authorization when checking in, and only freezes a certain overdraft limit on the cardholder's card. The actual consumption deduction and settlement will be made when the cardholder leaves the hotel. Not all POS can do credit card pre-authorization transactions. UnionPay only allows a few industries such as hotels and car rentals to activate this function.
