ABSTRACT:
Barcode imaging and laser scanning systems are disclosed having at least one processor storing barcode decoding algorithms each corresponding to a respective symbology. The at least one processor causes at least one LED and/or a projected laser beam of the barcode imaging system to blink by rapidly turning it off and on one time or several times whenever a successful decode occurs. In the laser scanning system, the at least one processor causes a projected laser beam to be blinked by turning a laser beam system off and on one time or several times whenever a successful decode occurs. The act of blinking the at least one LED and/or the projected laser beam in the barcode imaging system or the act of blinking the projected laser beam in the laser scanning system provides a visual indication to a user of a successful decode. The act of blinking can also be used to visually indicate other information to a user. The act of blinking can be replaced by the act of changing the brightness of the at least one LED and/or projected laser beam in the barcode scanning systems.
