A system and method of maintaining a bar code reader which bypasses a point-of-sale terminal coupled to the bar code reader. The system includes a maintenance computer, and a connection path between the maintenance computer and the bar code reader which bypasses a point-of-sale terminal connected to the bar code reader. The maintenance computer obtains bar code performance data from the bar code data over the connection path, determines the operating status of the bar code reader, and provides the operating status to a technician operating the maintenance computer.
