How a Japanese carmaker created QR codes that changed payments, travel and more
In today's fast-paced world, QR codes have become a near-ubiquitous part of everyday life. Whether it's scanning a restaurant menu, making digital payments, boarding a flight, or verifying products for authenticity, QR (Quick Response) codes have made transactions and access to information faster and small, square patterns of black-and-white modules may seem like a simple invention, but behind their creation lies an extraordinary story -- and an extraordinary man: Masahiro BEHIND QR CODES Masahiro Hara, the Japanese engineer who invented the QR code, transformed not just the way businesses operate, but also how people interact with technology globally.
Born in Tokyo, Japan, in 1957, Hara was always a curious mind, fascinated by puzzles and pursued his education at the Tokyo University of Science, one of Japan's most esteemed institutions, where he honed his skills in engineering and information CAREER AT DENSO CORPORATIONAfter completing his studies, Hara joined Denso Corporation, a leading automotive components manufacturer and a member of the Toyota Group. At Denso, Hara initially worked in product development and was involved in creating barcode scanning systems to streamline automotive manufacturing barcodes were effective, they had significant limitations -- they could store only a small amount of data and required precise alignment for OF THE QR CODE advertisementRealising the need for a more efficient system that could hold larger volumes of information and be scanned from any angle, Hara set out to innovate. Inspired by the principles of playing "Go," a traditional Japanese board game involving black-and-white stones placed on a square grid, Hara devised the concept of a two-dimensional code.

In 1994, after months of hard work and collaboration with his team at Denso, Hara developed the QR traditional barcodes, QR codes could store hundreds of times more data, including alphanumeric characters, and could be scanned swiftly from any direction -- a true ADOPTION AND APPLICATIONS Initially intended for tracking automotive parts, QR codes quickly found applications across industries worldwide, from retail and healthcare to entertainment and transportation. The technology's open patent policy further accelerated its global adoption, allowing businesses and developers to use it freely without licencing inventing one of the world's most widely used technologies, Masahiro Hara and Denso Wave chose not to patent the QR code, allowing it to be freely used and adapted globally. This decision greatly accelerated its adoption and QR codes were primarily used within factories for inventory management and logistics, and it was only in the early 2000s-with the rise of smartphones-that they began appearing in public-facing applications and gained widespread PERSONAL LIFE Hara is married and has children, though he has kept much of his private life away from the limelight. Even in recent years, he has shown keen interest in the evolving applications of QR codes, including their use in contactless payments and combating counterfeit every time we scan a QR code, whether to make a payment, download an app, or access exclusive content, we owe a silent thanks to Masahiro Hara -- the visionary who revolutionised the way the world connects information with action.
