Abstract
Abstract An improved portable terminal system is described employing linked data files to present related information on a configurable display device. The portable terminal uses a machine coded reader to read machine coded data on an item and to register such information in a corresponding collection file. The system retrieves associated data files and presents such files in the form of a link if such information is determined to be non-essential. Thus, non-essential data may be presented as optional available data which may be accessed with a simple election command.
