Abstract
A method of accessing a remote location on a network using an optical reader. The optical reader includes an optical scanning system, a programmable memory system and an output circuit and is user-switchable between a scan mode, a record mode and a playback mode. The optical reader transmits a code to a first computer disposed on the network. When the optical reader is in the scan mode, the code is indicative of information extracted from an encoded indicia just scanned by the optical scanning system. When the optical reader is in the playback mode, the code is indicative of information retrieved from a user-selectable memory in the programmable memory system. The information in the user-selectable memory was previously stored in the user-selectable memory after being extracted from an encoded indicia scanned by the optical scanning system when the reader was in the record mode. In response to the first computer receiving the code from the optical reader, a second computer disposed on the network is accessed. A lookup operation is performed at the second computer to match the code received from the optical reader with a routing information for a remote location on the network. The …
