What exactly does credit card blocking mean?

The hotel blocks a portion of your credit card balance to ensure that booking cancelation/no-show fees can be charged (if applicable).

Please note that when the amount is blocked, it is not charged: the funds are reserved for some time, but they remain on your account.

Many users are confused because when funds are blocked on their credit card, they receive the same SMS notification as when the credit card is charged. To enquire about the balance of your credit card, please contact the customer service of your bank.
