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 fit the academic calendar better and align with 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 testament to human ingenuity, perfectly embodies innovation. This square-shaped, two-dimensional barcode is transforming our day-to-day interactions.

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

QR code inventor

Masahiro Hara, a name often overlooked in the tech world, is the genius behind the QR code. 

In 1994, while working as an engineer at Denso Wave, a Japanese company, 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.

Before he came up with this smart tool, he had his eureka moment while playing the Go board game during lunchtime.

In an interview with Masahiro Hara in 2020, he walked us through his thought process on how he came up with such a brilliant idea:


“We had been making barcode readers for 10 years so we had the knowhow. I was looking at the board and thought the way the stones were lined up along the grids … could be a good way of conveying lots of information at the same time.”


And that’s how QR codes were born.

At the time, he had no idea this would be a groundbreaking invention.

He was amazed when the codes were used for payments. He’s even surprised when they became such a useful tool during the COVID-19 pandemic.


“I’m really pleased that it’s being been used to help improve people’s safety,”

“Back in 1994 we were focused on its use in the economy … we never thought it would be used for something like this.”


Initially designed for industrial use, the QR code has since evolved into a widely accessible tool. With the best QR code generator available online, it’s easy for anyone to create codes.

Hara's invention, once limited to factory floors, has become a democratized resource for businesses and individuals. 

Though we often take this technology for granted, it's important to recognize its creator's brilliance and foresight. Masahiro Hara's legacy lives on in every QR code scan.

What the numbers are really telling us

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 offline and online. 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.

💡 What this means: Mobile-first strategy is no longer optional. Brands must optimize everything, from campaigns to checkout experiences, with smartphones in mind. QR codes are the gateway to this mobile-first world.

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”

9 in 10 users scan a QR code at least once a week, and more businesses are catching up. 93% of marketers ramped up their QR efforts in the past year.

💡 What this means: QR scanning is now a natural consumer behavior, like tapping a screen or swiping a card. Businesses need to anticipate this behavior and build it into product labels, menus, ads, and in-store displays.

QR scanning is now second nature. Consumers expect it. Your signage, packaging, events, and ads should make scanning intuitive, fast, and rewarding.

Let’s be real. Scanning a QR code isn’t something people “learn” anymore. It’s automatic. Almost 90% of users scan at least once a week, without even thinking twice.

Point is, you’re not asking them to do something new. You’re meeting them where they already are. The only question is: what are you giving them when they scan?

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 also doing it. 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

QR code uses

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, travel, and 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.

Scan with caution

Here’s the catch: Behind every technological advancement and rising adoption come security risks.

Around 2% of scanned QR codes are malicious, and executives are 42 times more likely to face QR-based phishing attacks (aka quishing). It’s a real threat. So yes, go big on QR, but make sure your tech, your team, and your users are protected.

2% may sound small, but considering billions of scans occur daily, millions of devices are exposed to phishing.

Hackers now target high-value individuals with quishing (QR phishing). This makes security awareness vital.

💡 What this means: Security must also evolve to combat these security risks. Security awareness and QR code verification should be part of every company’s QR strategy.

If you’re scaling your QR code strategy, build in security from the start to stay ahead of evolving threats. Educate users. Vet QR destinations. Use safe and secure QR code generators that comply with the highest security and privacy standards.


From tiny beginnings to global impact

QR codes have undergone an extraordinary evolution, transforming from a simple tool for tracking cars on assembly lines to an indispensable part of our daily lives. 

This small square barcode has made a lasting impact, from the busy metropolis to the quiet rural areas.

The introduction of advanced QR code generators has democratized this technology, allowing both individuals and businesses to create and use QR codes for a wide range of applications. 

Whether it's sharing contact details or accessing digital menus, the possibilities are limitless. World QR Code Day is the perfect time to honor this remarkable invention. 

It's a day to celebrate the creators' ingenuity, the technology's versatility, and the many ways it has enriched the world. We can only be excited about the new and innovative uses that will emerge.
