đź“° The History of the QR Code:
From Toyota to Smartphones

The invention of the QR code: solving an industrial problem
The QR code — short for Quick Response code — was born in Japan in 1994, in a setting far from today’s marketing or social uses.
At the time, Denso Wave, a subsidiary of Toyota, was looking for a faster and more reliable way to track car parts during assembly.
Traditional barcodes were no longer efficient enough: they could only store a small amount of information and had to be scanned in one direction.
An engineer at Denso Wave, Masahiro Hara, came up with a new two-dimensional code that could hold more than 100 times the information of a standard barcode.
The QR code was officially born — simple, powerful, and fast to scan.
A free and open format
One of the key reasons behind the QR code’s rapid success was Denso Wave’s decision to make the technology freely available.
The company chose not to enforce patent rights, allowing anyone to use and develop QR code systems.
This openness led to massive adoption across industries — from logistics and manufacturing to retail and, later, marketing.
The rise of QR codes in everyday life
In the early 2000s, QR codes started to appear in advertising, packaging, and magazines.
However, their use remained limited because users still had to install a dedicated app to scan them.
Everything changed around 2017–2018, when Apple and Android added native QR code scanning directly into smartphone cameras.
With a simple point of the lens, users could now open links, menus, or forms instantly — no extra app required.
The boom during the pandemic
The COVID-19 pandemic turned the QR code into an everyday essential.
From contactless menus and check-in forms to vaccine certificates and online payments — QR codes became a universal bridge between the physical and digital worlds.
Within months, billions of people rediscovered this simple but powerful tool.
Since then, QR codes have become a permanent part of modern life: restaurants, events, business cards, shops, and even museums rely on them daily.
QR codes today: a universal tool
Today’s QR codes can do much more than open a website. They can contain:
- web links
- contact information (vCard)
- WiFi network connections
- files, videos, or applications
- even contactless payments
Their simplicity and versatility make them one of the easiest and fastest ways to share digital information — instantly and universally.
A connected future
With the rise of the Internet of Things (IoT), QR codes are continuing to evolve.
We now see dynamic QR codes that can be updated or tracked for marketing campaigns, and custom designs that include brand colors and logos.
Despite new technologies like NFC, QR codes remain unbeatable in one respect:
👉 they work anywhere, on any device, without the need for an app.
What’s next for QR codes?
The QR code’s future looks bright.
As smartphones and connected devices keep improving, QR codes will become smarter, more attractive, and more useful.
We already see colorful, branded QR codes that match company identities.
Soon, they could be animated or interactive, appearing on screens, digital displays, or connected products.
QR codes will also play an important role in product traceability (food, medicine, or logistics) and authentication — helping verify the origin and safety of items.
In short, QR codes are here to stay, quietly becoming an even bigger part of our connected lives.
