How to use the hotel POS machine, what are the pre-authorization, consumption and freezing? According to the pre-authorization when collecting the deposit, how to confirm the consumption when checking out? thank you Pre-authorization is to temporarily freeze the money in your account and authorize the hotel to deduct the room rate when it is not received; Consumption means withdrawing money directly from your account. Pre-authorization is required when collecting the deposit, and another list will be issued when checking out, indicating that the pre-authorization is completed. If the pre-authorization is unsuccessful, you will be prompted to spend money, and the pre-authorization triple sheet will be returned to the customer or torn up in person, because the bank is cash with documents, and the hotel can't receive money without bills. So if you don't check out at the front desk, there is no guarantee that the pre-authorized triple order will be processed, and the hotel can deduct all the money at any time.
