It’s Everywhere! The Captivating Story of the Bar Code

As a technology, bar coding is so entrenched in all aspects of everyday commerce and our daily lives that it’s often taken for granted.

The story of its universal success though is a fascinating and lengthy one. The condensed version began in the US in the late 1940s, when the president of a local food chain asked Philadelphia’s Drexel Institute of Technology to research an automatic system for reading product information at checkout.

Drawing a Line in the Sand

Graduate students Bernard Silver and Joe Woodland tackled the project, and it was Woodland who made the initial breakthrough. He believed that the dots and dashes of Morse code would make an ideal model. While relaxing on the beach, he idly drew some dots and dashes in the sand with his fingers. When he elongated these into vertical lines, he realized that he’d had a eureka moment – in effect, the linear binary bar code as we now know it.

Woodland and Silver patented their linear “bar code”, along with a circular version (which they favoured) and a workable reading system in 1952, but it would take years of enormous effort and research from multiple parties and individuals to produce a viable system.

The Wrigley’s “First Scan” Event

All of this work, including the unrelated invention of the laser by 1960, and the development of the linear Universal Product Code (UPC) for groceries in 1973, culminated in the famous “first scan” of a UPC bar code. This was a “10 Pak” of Wrigley’s chewing gum on 26 June 1974 at a Marsh supermarket in Troy, Ohio, USA – the cashier Sharon Buchanan, the scanner a PSC Magellan (brand names now owned by Datalogic).

Bar Coding Goes Viral

Still, uptake by industry wasn’t as rapid as predicted. It wasn’t until the early to mid 80s that critical mass was achieved in the US grocery market due to bar coding’s (by then) undeniable benefits of increased productivity and accuracy, and savings in time and costs. Bar coding soon spread into other markets along the supply chain including retail in general, logistics, transport and manufacturing, as well as fields undreamt of at first such as healthcare, government, education and defence.

Kemtek Enters the Market

Kemtek, already respected as a major distributor of sophisticated industrial printing technology throughout Southern Africa, entered the bar coding market in 1988.

With this solid foundation in national distribution at scale, Kemtek began forging ties with global bar coding original equipment manufacturers and importing their equipment to supply to resellers nationally.

Designs & Symbologies: Bar Coding 101

Bar code designs and symbologies have grown exponentially since George Laurer’s first UPC 1D code, including 2D and QR codes, though some early 1D codes are still in use.

Kemtek principal, Datalogic, provides a comprehensive and very informative analysis of bar code symbologies – in essence, Bar Coding 101 – that is available here:
