The present invention relates to a universal advertising and payment system and method for retail store applications including point of sale transactions, and window display transactions. Additionally, the present invention relates to transacting e-mail, e-commerce, and e-business and for communicating voice and data. Furthermore, the present invention relates to a universal advertising and payment system and method for networking, monitoring and effectuating e-mail, e-commerce, and e-business and controlling vending locations and equipment. The system can effectuate electronic commerce and interactive advertising at the point of sale in this instance in retail stores as a point of sale device and in storefront window displays. Vending locations and equipment includes point of sale systems, property management systems, management information systems, and retail stores including credit card processing terminals and retail store window display areas. In addition, vending equipment can include copiers, phones (public, private, cellular), facsimile machines, printers, data-ports, laptop print stations, notebook computers, palmtop computers (PALM PILOT), microfiche devices, projectors, scanners, cameras, modems, communication access, personal data assistants (PDA's), pagers, and other vending machines, personal computers (PC), PC terminals (NET PC), and network computers (NC). Vending locations and equipment can be networked to each other through a first network, programmable and accessible by a PC, server, point of sale (POS) system, property or management information system (PMS/MIS), and networked to a second network.
