A mail order firm receives a request for purchasing an article through Internet and the destination address. The terminal at the mail order firm converts the destination address into latitude and longitude position data to record it on an ID tag with a reader writer. The ID tag is attached to a freight containing the ordered article. A site receiving the freight reads the latitude and longitude position data to print or display the destination address in the language used by the site dealing with the freight. The deliverer can confirm that the present location where the freight is handed agrees with the latitude and longitude position data of the destination with navigating unit and GPS receiver.
