The invention of the QR code

The Man Behind the Squares That Changed the World

In a quiet corner of Japan, in the early 1990s, a humble engineer named Masahiro Hara stared at a problem that was frustrating industries everywhere: barcodes. They were clunky, slow, and couldn’t hold much data. The world was speeding up — but these little stripes just couldn’t keep pace.

Masahiro worked at Denso Wave, a company in the auto industry, where speed and precision were everything. He needed something better — smarter.

Then one evening, while relaxing over a game of Go, a centuries-old board game of black and white stones, inspiration struck. The layered complexity of the game… the elegant way patterns carried meaning… what if information could be stored like that?

That was the spark.

What followed was a quiet revolution. Masahiro and his team created a new kind of code — one that didn’t just improve on the barcode, but reimagined it entirely.

It could be read in any direction.

It could survive damage and still be scanned.

And it could hold hundreds of times more information.

They called it the QR code. QR meaning Quick Response.

It didn’t make headlines. It didn’t launch with fanfare. But like all great inventions, it spread — silently, efficiently, and universally.

Today, Masahiro’s invention touches nearly every part of our lives. We scan QR codes to read a restaurant menu, make a payment, access our medical history, join virtual events or send a digital hug across the world

All from a tiny black-and-white square.

Masahiro Hara never sought the spotlight. But his creation — born from a quiet game of Go — now lives in the pockets, screens, and lives of billions.

Because sometimes, the biggest breakthroughs come not from force… but from seeing an old problem through new eyes.
