Can I swipe my savings card at the hotel?

No Only credit cards can pre-authorize consumption.

The credit card was pre-authorized when you checked in at the hotel, and you didn't pay it, but temporarily frozen this part of the credit limit. Pay for the room by swiping your card when you leave the hotel. Pre-authorization will unfreeze pre-authorization funds after the hotel checkout operation. If the hotel is closed, the bank will automatically unfreeze it within a certain period of time (20-45 days).
