A method and system for allowing the setting of reservations and the pre-authorization of credit to purchase a desired service for which a reservation is made. A customer accesses a reservation system that is integrated with a credit authorization system. The customer may make a reservation and substantially simultaneously become pre-authorized to pay for services to be provided at the reservation by one of any number of credit providers. Pre-authorized credit and reservation information is then supplied to the service provider in advance of services being provided, expediting the overall transaction time and allowing for a secure and cardless transaction procedure. The reservation and preauthorization information are typically stored upon the reservation system and then passed to the point-of-sale systems, but other types of input/output storage devices could be used to perform this function.
