Abstract: An interactive, customer-accessible data processing system embodied in a programmed personal computer that induces customers of a restaurant, store or other business to enter information about themselves into the system. The information, which may include names, addresses, dates and answers to survey questions, is entered into data fields displayed on a display screen. The system enables a business to generate promotional messages tailored to customers based on the customer-entered information. For example, a business can readily generate birthday offer letters to customers based on their name, address, and birth date simply by selecting an option provided by the system. To induce customers to enter the necessary information, the system flashes an incentive message on the computer display screen. The message may offer to enter a customer into a drawing or other contest in return for the customer entering the necessary information into the system.
