US Patent 9412231 Method and apparatus for integrated customer tracking and browsing

A system and method for tracking customer activity without need for an extensive interconnecting network. The system includes a plurality of gaming devices that are communicatively isolated from one another. Information, including tracked customer activity, bonus requirements, and in one embodiment, personal information, is stored on a memory device communicable with the gaming devices. This allows implementation of an incentive program at reduced cost because the service devices themselves need not be networked together.
