How do American hotels collect deposits from their guests? Just copying their credit cards.

This is not just a demonstration. Old-fashioned hotels will use a printer to record all the information of credit cards (including concave-convex card numbers), so they can replace the power of attorney as collateral. But its disadvantage is that it can't know the balance on the card, and it will be pressed if it is not skilled in operation, so it is only used in some old hotels in Europe and America ~

At present, the common practice is to brush pre-authorization, that is, card authorization or card verification, but some Americans still get used to calling it imprint. After brushing, the corresponding amount will be frozen as a deposit, but the money has not been taken away. When checking out, swipe your card again for pre-authorization to complete the authorization, deduct the payable fees from the frozen amount, and unfreeze the balance ~ If you use other cards or cash to settle the bill, the hotel will contact the bank to unfreeze it ~ It's okay if you don't unfreeze it, and it will be unfrozen automatically after 30 days of pre-authorization ~
