Pre-authorization cancellation of Jiangsu bank savings card

The money returned to the bank card in the pre-authorization requires the merchant to cancel the authorization.

Bank cards are frozen (pre-authorized) by hotels and other businesses, and after the specific amount is confirmed after consumption, it is equivalent to a "deposit". If you don't want to spend, the balance will be returned to the bank card;

If the bank cannot unfreeze, even if the pre-authorization is not cancelled, the merchant who swiped the card can be required to cancel the pre-authorization and return the money to the withdrawal account; If there is no consumption, the pre-authorization will be cancelled automatically after one month.
