A month of innovation deserves an innovative icon
August once stood as a month devoted to celebrating the minds behind groundbreaking inventions.
National Inventors Month was first recognized in August 1998 by the United Inventors Association of the USA (UIA-USA), the Academy of Applied Science, and Inventors Digest to honor creativity, ingenuity, and the courage to experiment.
However, in 2011, the celebration was moved to May to better align with the academic calendar and the National Inventors Hall of Fame ceremony.
While May now shines as the month of invention, August remains historically tied to innovation. It’s a time that still resonates with the spirit of discovery and the excitement of groundbreaking ideas.
To fill this gap and honor August's innovative legacy, the world now celebrates World QR Code Day on August 21st.
The Quick Response (QR) code, a square-shaped, two-dimensional barcode that is transforming our day-to-day interactions, is a testament to human ingenuity and perfectly embodies innovation.
QR codes symbolize progress, making the phygital world a reality. By dedicating a day to this technology, we can celebrate this remarkable invention and honor the spirit of innovation that has long defined August.
Honoring the mind behind the code
Masahiro Hara is the genius behind the QR code.
In 1994, while working as an engineer at DENSO WAVE, a subsidiary of the Toyota Group, Hara was tasked with finding a more efficient way to track vehicles on assembly lines as the world was poised for a digital transformation.
His clever solution was a two-dimensional barcode capable of storing far more information than traditional barcodes.
In a recent interview, Masahiro Hara shared his firsthand experience of seeing manufacturing plant operators struggle to scan multiple, oil-covered one-dimensional barcodes for a single product.
“Before I invented the QR code, I was a developer of a barcode reader device. I started visiting my company's manufacturing plant, and they were actually struggling.
Sometimes, to manage one product, they had to print 10 barcodes because a single barcode could only store a limited amount of information.
I wanted to do something to help those operators, and that's what brought me to decide to develop the QR code.”
At the time, he had no idea it would be a groundbreaking invention, thinking it would just be another tool used by factories, retail shops, or even offices.
He was surprised when people started using QR codes as tattoos, and years later, was amazed at the prospect of using them to store facial data for authentication.
“Back in 1994, we were focused on its use in the economy. We never thought it would be used for something else.”
“Looking back over 30 years, I am most proud of the fact that QR codes have helped society in a better way.”
Once limited to factory floors, QR codes have become a democratized resource for businesses and individuals after they were made license-free.
The QR code generator and management platforms continue the legacy of producing QR codes that help businesses serve mass consumers, run campaigns, and streamline operations.
For Masahiro Hara, innovating with users in mind naturally enables anyone to create and make an impact, even in the face of setbacks.
“If you are thinking about bringing, making things better, that will also help you innovate a wonderful thing,” he said.

If there’s one thing the latest data makes clear, it’s this: QR codes are no longer optional. They’re essential.
QR codes aren’t just a trend. They’re reshaping how we interact, pay, market, and share information.
Across industries and countries, we’re seeing a massive shift in how people connect through digital touchpoints. And at the center of it all? The humble QR code. Smarter, sleeker, and more strategic than ever.
Here’s what the QR code statistics report is saying, with insights into what it means for businesses and consumers:
QR codes are taking over, and they're just getting started
A 22% global growth in QR code usage this year? That’s not just a spike. It’s a signal. U.S. adoption alone is pushing past 100 million users.
💡 What this means: QR codes have officially gone mainstream. It isn’t just a passing trend; it’s a long-term behavior shift.
They’re now a universal access point for digital experiences used by consumers and businesses alike, in nearly every industry.
If your brand still treats QR codes like a sidekick, you’re missing the main plot.
Here’s the bottom line: QR codes have become the default bridge between the offline and online worlds. You're already behind if your business still treats them like a novelty.
Mobile-first isn’t just a trend. It’s the playbook.
With 59% of smartphone users scanning QR codes daily and nearly 1 in 3 using them for payments, we’ve officially entered a mobile-first world. And QR codes are leading the charge.

Let that sink in. Your customers are now scanning, tapping, and transacting on the go, so your strategy needs to live in their hands.
Whether you're building a product, running a campaign, or rethinking customer experience, design with the mobile scanner in mind.
Scanning will be the “new norm”
According to an industry report published by QR TIGER in 2026, 47% of QR code users now scan QR codes daily or several times per week.
💡 What this means: QR scanning is now a natural consumer behavior, like tapping a screen or swiping a card. Businesses have even begun including QR codes in product labels, menus, ads, and in-store displays.
The same report found that QR code usage has increased by 70%, with more than half of users saying that they use QR codes more often now than they ever did in 2023. Scanning is no longer something people need to learn; it's something most do on a regular basis.
For many businesses, this means that the new goal is to determine what users want to see when they scan a QR code, rather than teaching them how to scan one in the first place.
QR code-powered campaigns are driving real results
We're not talking vanity metrics. On average, QR-powered campaigns deliver a click-through rate of 37%. That’s leagues ahead of many digital ads. Plus, 95% of businesses say QR codes are helping them collect crucial first-party data.
💡 What this means: QR codes are a marketer’s best friend. They engage users, collect valuable data, and offer real-time tracking.
Think about the industry giants like Amazon, Nestlé, McDonald’s, Pepsi, Coca-Cola, and Walmart. These giants are crushing QR code-powered campaigns.
More local and international brands are doing it as well. Why? Because QR codes give them the power to convert, connect, and gather real-time campaign data through a single scan. Plus, they fit into their audience’s mobile-first lifestyle.
More creative QR code uses are emerging
Those plain QR codes? They’re evolving. From plain black-and-white squares, we can now see customized QR codes, AI-designed QR art, logos embedded in the codes, and even QR tattoos that actually work.
Plus, big brands are using them for way more than links. They use QR codes for smart and interactive packaging, event check-ins, loyalty programs, promos, AR/VR, and games.
💡 What this means: QR codes are no longer just static, plain, boring squares. They’re smart and versatile. They’re being reimagined as interactive, branded, and even artistic tools that enhance user experience and build stronger brand identity.
Today, QR codes are becoming more than functional. They’re becoming an experience.
The best QR campaigns don’t just redirect; they delight. A well-placed, well-designed QR can elevate the customer journey in ways that are memorable and measurable.
Creativity wins. When you combine function and flair, people don’t just scan. They remember.
QR code is the future…in life and business
QR payments are expected to hit over $3 trillion this year. That’s not a small corner of the market. That’s a full-on shift.
Countries across Asia are building cross-border QR systems. It’s fast. It’s seamless. It’s changing how people transact, travel, and connect.
💡 What this means: QR codes are shaping the future of digital and physical interaction. QR codes are at the center of everything from how we pay and travel to how we experience.
Here’s the big picture: Sustainability, convenience, and real-time data drive QR's rise. From packaging to point-of-sale to public transport, the tech is quietly but powerfully transforming how the world works.
If you think QR is just a marketing tool, think again. It’s infrastructure now.
