If a position detection pattern is used in a code and there is a similar-looking mark nearby, the code reader may mistake it for the position detection patterns. To avoid this type of erroneous reading, their position detection patterns had to be truly unique. After mulling over this problem thoroughly, they decided to do an exhaustive survey of the ratio of white to black areas in pictures and symbols printed on fliers, magazines, cardboard boxes and so on after reducing them to patterns with black and white areas. They continued the task of surveying innumerable examples of printed matter all day long for days on end. Eventually, they came up with the least used ratio of black and white areas on printed matter. This ratio was 1:1:3:1:1. This was how the widths of the black and white areas in the position detection patterns were decided upon. In this way, a contrivance was created through which the orientation of their code could be determined regardless of the angle of scanning, which could be any angle out of 360°, by searching for this unique ratio.

As American dissatisfaction with waiting in line grew throughout the 50s and 60s, IBM set to work in the early 1970s to revisit the earlier patented technology. And IBM, in coordination with the grocery industry, developed the vertically-aligned UPC barcode we know today. The idea was to create a universal system of product identification and processing. A system that didn’t rely on manually entering numbers anywhere, but on fast optical scanning. Point-of-sale (POS) systems and scanners were required to scan and process the new UPC barcodes. Those were sold and distributed by IBM. By the late 1970s, checkout lines had sped up 40%. Throughout the 80s, thousands upon thousands of grocery and retail stores adopted the technology. By the 2000s, the barcode business had a value of around $17 billion. Billions of items are now scanned every day in every industry across the world.
