Abstract
A hand-held, dual-mode barcode scanner for two dimensional barcodes. A supplemental switch activatable by the user changes the function being performed by the scanner. In one implementation, the barcode data is used to reprogram the scanner's logic when the supplemental switch is activated. The preferred embodiment employs a light-activated switch that is turned on by the user placing his/her finger/thumb over an opening in the scanner case. An infrared-activated version of the switch is also shown.
