Behind The Many Lines Of A Bar Code

By definition, a “bar code” is optical data which can be read by the scanning device of bar code equipment, which is then interpreted by software. Earlier bar codes used to come in the form of parallel black lines called linear or one-dimensional bar codes. Today, however, bar coding equipment can read all sorts of patterns, such as squares, dots, hexagons or other geometric patterns called two-dimensional matrix codes; and though these symbols are not bars, they are still referred to as bar codes.

The first bar code equipment was used in supermarket and retail stores to automate their checkout and point of sales systems. Bar code equipment has, since, been used in many other industries and for many other applications the world over. In fact, various types of bar codes and bar coding equipment are now available in the global market.

There are many components to bar code equipment; such as optical scanners or bar code readers, which (as the name implies) reads the bar codes scanned from an image utilizing special software, which is actually the same software used in Smartphone platforms. The other components of bar code equipment are the bar code printers, screen displays and central processing units (CPUs), which are compact, mobile and flexible to fit any type of space.

Possibly, the most recognizable component of bar coding equipment is the bar code scanner; which you can identify by the red laser lights that appear when a bar code is being scanned. As the main component of bar code equipment, bar code scanners utilize special decoding technology which can interpret bar codes up to 4.7 inches in length at a distance of up to 4.7 inches.

Bar code scanners contain no moving parts and may be used as hand-held devices or as fixed bar code equipment. The hand-held scanner is exceptionally lightweight and ergonomically designed to fit comfortably in your hand even for long periods of time. This bar coding equipment component can even scan low-quality or damaged bar codes with outstanding speed and accuracy. The other components of bar code equipment were designed to be mobile, light and compact so for space management purposes.

Bar coding equipment has, indeed, changed the world we live in greatly. Perhaps driven by the need for speedier and more accurate transactions, bar code equipment has become an indispensible part of our day-to-day lives.
