Production, shipping, issuing transaction slips, and many other operational processes became more streamlined thanks to QR codes.Īs a means to make products more traceable pharmaceutical, food, and contact lens companies joined the automobile industry by adopting the QR code. The benefits of 2-dimensional scanning technology came tenfold.

Eventually, the QR Code was picked up by the auto industry due to Toyota’s dissatisfaction with previous barcodes in their factories. Hara truly pounded the pavement and made sure the word got out to various industries and organizations. It only took a year and a half for Hara to develop a QR code that could be read 10x faster than other codes. Hara’s team realized that the orientation of the code could be ascertained regardless of the scanning angle after looking for the ratio. After extensive research on the various ratios of white-to-black areas in pictures and symbols on various kinds of print, Hara and his team discovered the least common black and white areas on printed matter 1:1:3:1:1. Code readers can mistake similar marks for position-detection patterns, so Hara’s codes needed to be unique. The markings had to be squares because such a pattern was unlikely to appear on business forms and other similar documents. This revelation made high-speed reading possible. The position-detecting pattern, consisting of square marks, was developed when Hara realized the speed problem could be rectified with positional information signaling the existence of a code being read. Hara’s toughest obstacle was the speed at which codes could be read. Unlike other developers, DENSO’s Masahiro Hara aimed to create 2-dimensional code that could be easily read and could hold tons of information. Developers at other companies wanted to blindly cram as much information into codes as that they possibly could. What makes 2-dimensional codes unique is that information is coded horizontally and vertically, whereas 1D only codes in one direction. From there, DENSO WAVE began developing 2-dimensional codes to meet the needs of the market. Unfortunately, the barcode could only hold approximate 20 alphanumeric characters of data and its limitations became more evident as consumer demand increased.ĭENSO WAVE Inc., a company that developed barcode readers, was asked to develop technology that could code Kanji and Kana characters on top of alphanumeric ones. Simultaneously, the information on the item was transferred to a computer. The influx of customers brought on by a robust economy caused an epidemic of carpal tunnel syndrome in cashiers, who became desperate to find some relief.Ĭashiers’ pleas for a lightened load were remedied with traditional barcodes and the POS system, where a cash register displays the price of an item after the barcode was scanned by an optical sensor.

Cashiers were still stuck with manual price input. The abundance of wealth led to supermarkets sprouting up in almost every neighbourhood. Japan’s economy reached new heights in the 1960s. Now, read on for a history lesson and deep dive into the expansive world of QR codes: The early stages of development Try scanning the QR code I used as an example, it just takes you to Logmore Web, which is also very much worth exploring. the data can be split across multiple codes which reconstruct the original content when scanned). Other advantages include dust and damage resistance, readability from any angle or direction, and structured appending (i.e.

You can even scan them with a smartphone app with a camera and a decoding algorithm. The QR code is versatile and flexible because scanning it doesn’t necessitate unique, costly hardware.
