System for navigating a visitor to a destination location in a building

摘要

An integrated reader and access control device is provided for graphically guiding visitors of a building to a destination location along a shortest path. The device comprises: a means for receiving a user's identification code, and a user's destination location; a processing means for accessing a current floor plan of a location, determining non-accessible areas in the location based on the user's identification code, and computing a shortest path from a present location to the destination location, wherein the shortest path circumvents the non-accessible areas; and an output means for graphically displaying the shortest path on a map of the building. An access control device may be placed at each access point of a building. A visitor may be provided with an access card programmed with a unique card number and a destination location. The non-accessible areas may be restricted areas based on an access level of a visitor.
