QR codes are everywhere - on product packaging, restaurant menus, event tickets, and marketing campaigns. But few know the captivating story behind these ubiquitous black-and-white squares. In this post, we’ll explore who invented QR codes, why they were created, and how they became an indispensable part of the digital age.
In 1994, Masahiro Hara, an engineer at Denso Wave (a Toyota subsidiary), invented the Quick Response (QR) code.
Denso Wave needed a faster, more powerful way to track parts on its manufacturing lines. Traditional barcodes were limited - capable of storing only 20 - 25 characters and requiring linear scanning. Hara revolutionized the concept by designing a 2D matrix barcode system that could store far more data and be scanned 360° from any angle.
Key motivations behind the invention:
Though Denso Wave obtained a patent, they made a strategic decision not to enforce it. The QR code system was published as royalty-free technology - a rarity for patented inventions. This openness allowed for unrestricted global use, fostering innovation and integration across industries.
Originally used for logistics and supply chain tracking, QR codes began their rise in popularity in the 2000’s :
By the 2010s (and supercharged during the COVID-19 pandemic), QR codes became a go-to for :
Modern QR technology has evolved far beyond its original scope:
Platforms like Enqode QR make these advanced features accessible, empowering businesses to harness dynamic, data-driven engagement.
Who owns the QR code patent now?
Denso Wave still holds the patent but has made the technology free-to-use globally - no royalties.
What does QR stand for?
“Quick Response” The name reflects the speed and ease with which these codes can be scanned and decoded.
Are QR codes still relevant?
Yes! With contactless tech and mobile-first behaviors skyrocketing, QR codes are more useful - and widely adopted - than ever.
The story of the QR code is a powerful reminder that ingenious solutions often arise from simple needs, evolving into transformative global tools. Masahiro Hara's foresight in designing a multi-directional, high-capacity barcode laid the groundwork for a technology that now powers everything from contactless payments to interactive marketing. As we look to the future, the QR code continues to evolve, offering dynamic features, deeper analytics, and personalized experiences. Platforms like Enqode QR proudly build on this legacy, pushing the boundaries of what's possible and helping you unlock the full potential of this ever-evolving technology.
