A method for graphically guiding visitors of a building to a shortest path using an integrated reader and access control is provided. The method includes receiving a user's identification code, receiving a user's destination location, uploading 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.
