Electronic coupon storage and retrieval system correlated to highway

Abstract

A system for providing data related to discounted services available near a given location. The system includes a memory storing compressed service data representative of a plurality of services in various locations categorized by type of service and compressed coupon data representative of discounts available for the services. The system also includes a book of coupons corresponding to the discounted services wherein the coupon data includes identifying numbers which identify locations of coupons within the coupon book corresponding to the discounts available for the services. A data entry circuit receives and compresses input data identifying a desired category of services and the given location and a microprocessor, receiving and responsive to the compressed input data, selectively retrieves the service data and coupon data from the memory. The retrieved service data represents one or more selected services in the desired category near the given location and the retrieved coupon data represents the discounts available for the selected services including the identifying numbers of the coupons. The microprocessor then expands the retrieved service data and coupon data into a user-readable form and a display displays the expanded retrieved service data and coupon data.
