1. The use of credit cards to pay hotel deposits is completed through the credit card pre-authorization business. The so-called credit card pre-authorization refers to the card issuer or its agency making a special appointment. Before the merchant debits the money, confirm the transactions that allow the frozen amount. That is to say, hotels and other merchants can swipe a credit card pre-authorization when the cardholder checks in. This amount will occupy the original limit of the credit card, and the credit card pre-authorization will be settled when the cardholder leaves the hotel.
2. If the cardholder makes other consumption at the hotel and confirms that he wants to pay the consumption with a credit card, the hotel will deduct a certain amount from the frozen pre-authorized amount according to the actual consumption. If the amount is not enough, the hotel will deduct the amount from the credit card. The amount will be deducted from the amount, and the above process is called pre-authorization to complete the transaction.
Extended information
Authorization
The merchant and bank confirm that the credit card is valid, and contact the bank to request authorization according to the contract signed with the card issuer. Authorization is to further confirm the cardholder's identity and the amount that can be used. Authorization is generally made when the usage amount specified in the contract is exceeded.
After receiving the authorization notice, the card-issuing bank will issue an authorization instruction based on the deposit balance of the cardholder's deposit account and the bank's agreement to allow overdraft, and reply whether it agrees to conduct the transaction.
