The scanner is equally able to read bar codes molded in rubber, stamped in metal or embossed in any other material. When the trigger on the reader is pulled, a laser beam is projected across the width of the bumpy code. The light is immediately reflected back to the reader and collected by the CCD array. Compared to the original laser beam, the reflected light is captured at slight angles representative of the differences in height between the bumpy bar code bars and spaces. These angles are then digitized and processed by an onboard digital signal processor chip.
Processing determines the actual differences in height between the bars and spaces.
Using standard bar code symbology look-up tables, a decoder then translates this data into a human readable identifier. Inc. All Rights Reserved.
