Why is SMS prompt the consumption after pre-authorization of credit card?

The most common function of credit card pre-authorization is the deposit when staying at the hotel. Under normal circumstances, the hotel front desk staff will ask consumers to pay a certain deposit in advance. At this time, cash can be used as the deposit, or pre-authorized deduction can be made by credit card.

Merchants deduct the credit card usage quota, which belongs to the fund freeze, but it is not the actual consumption in the real sense. Most banks will also increase the overdraft limit of 15% on the basis of the actual pre-authorized deduction amount, which is also a preventive guarantee for banks themselves.

3. Proactive confirmation after the credit card transaction is completed: After the check-out and rent withdrawal procedures are completed, the cardholder should also consciously ask or confirm the relevant merchants to cancel the pre-authorization immediately, so as to eliminate possible risks and losses while restoring the quota.

4. Cancel in time and keep the voucher: if you plan to cancel the reservation, you should ask the hotel or agency to go through the pre-authorization cancellation procedures within the specified time limit and ask for the cancellation number as the cancellation voucher. Because after using the pre-authorization, if it is not cancelled in time, the merchant can withdraw money directly and the bank will not refuse to pay.
