Of all of the curiosities of design, mechanics, and engineering science that we see everyday, barcode scanners are certainly one of the most intriguing as well as one of the most forgotten. Most citizens never really think twice about them, even though they in all probability see them every day. Since they are so frequent, being used in every business organization from super markets to computer sites, they are virtually always taken for granted. Interestingly enough, though, this idea was only thought of roughly half a century ago, while the current technology and implementation are surely a far cry from its original roots. The following is a brief story and look into the astonishingly riveting world of barcode scanners.

Bar codes and the consequent scanners were not dreamt up until around the middle of the 20th century. A grocery store owner in New England withed for a quicker way to organize, identify, and check out goods. Two graduate students came to his assistance, eventually legally protecting a bar code that was prepared of a set of concentric rings, so it would be the same no matter which direction it was glanced over from. Although the technology was in front of its time and very coordinated, it wasnt actually put to use in supermarkets first, or any consumer store for that matter.

Railways were the original to use bar codes, although they would seem very fundamental compared to what we now connect with bar codes, such as an UPC code. In the mid 70s, the original bar code scanner was put in in a super market in Troy, Ohio, and everything since then is bar code chronicle. Now there are four main types of scanners, with many more falling into those categories. Also, there are definitely hundreds of bar codes for every use between simplistic consumer shopping and stockpiling and organising military armaments.
