Long bar codes are commonly used in a variety of applications including, utilities bills, document processing and packaging. these long codes are a challenge for full area imagers to read due to their narrow field of view and shorter depth of field. the quickscan qm2131 imager's extra-wide field of view and extra-long scan line makes reading long bar codes in closer distances much easier. the sharp and highly visible scan line makes the scanner more user-friendly to use, while the enhanced depth of field enables bar codes to be read at an intuitive distance. the stylish design is the signature of the quickscan series, completing a consistent family appearance. featuring datalogic's star 2.0 cordless system for narrow band 433 mhz radio communications, the qm2131 linear imager provides secure radio communications with no risk of interference from wi-fi infrastructure and very low sensitivity to obstacles like concrete walls, wood or metal shelves.
