1. Hotels, guesthouses and banks are all units with members, so the first way of cooperation is to discount or give priority to cards. 2. For those who stay in the hotel for more than 3 days, they can provide some local tourism, investment, travel guidance and car rental convenience. 3. Bank customers can rent a car free of deposit when the deposit reaches a certain amount, because the most worrying thing about renting a car is the deposit. A bank account is a deposit. These convenient conditions are equivalent to the introduction of a value-added service by banks, hotels, guesthouses and other enterprises, which is a bargaining chip for cooperation. Because they don't have to pay any price for it, they just need to add a paragraph to the leaflet.
