Abstract: An optical reader for accessing a remote location on a network includes an optical scanning system, a memory system, an output circuit for interfacing to a first computer disposed on the network, and a switching device for switching between a scan mode, a record mode and a playback mode. The optical reader further includes a transmitter for transmitting code information representative of a code to the first computer. In the scan mode, the code information is indicative of information representative of an encoded indicia scanned by the optical scanning system. In the playback mode the code information is indicative of information retrieved from a user-selectable memory in the memory system. The code information is configured to cause the first computer to determine routing information to the remote location, and access the remote location on the network in accordance with the determined routing information.
