Instead of just showing it, old-fashioned hotels will use a card press, that is, imprint, which will record all the credit card information (including the embossed card number), so it can be used instead of the authorization letter as a mortgage. However, its disadvantage is that it is impossible to know the balance on the card, and if you are not skilled in operation, the card will be crushed, so it is only used in some old-fashioned hotels in Europe and the United States~

The more common method now is to swipe pre-authorization, that is, card Authorization, or card verification, but some Americans are still used to calling it imprint. After swiping, the corresponding amount will be frozen as a deposit, but the money will not be transferred. When checking out, the card will be swiped again for pre-authorization to complete the authorization complete. The fees payable will be deducted from the frozen amount, and the balance will be unfrozen. If the payment is made with another card or cash, the hotel will contact the bank to unfreeze. It will not be unfrozen. No problem, the pre-authorization will be automatically unfrozen within 30 days~
