When I went to the hotel, I only swiped my debit card once when I checked in, but I didn't swipe it when I checked out. Will the deposit be refunded to my card?

It will be returned. I suggest going to the bank to check the detailed consumption list and see the balance.

If it is prepaid, the account will not go to the hotel account. After the guest leaves, the hotel can manually deduct the actual consumption on the POS machine, and the actual consumption is in the hotel account.

Completing the online connection also unfreezes the remaining balance, and the unfreezing time depends on the operation speed of the bank. The rest of the balance was in the card from beginning to end.
