The Genius Behind the QR Code: Who Really Invented It?
We scan QR codes every day—while paying for tea, booking train tickets, or verifying Aadhaar. But do you know who the real QR code inventor is?
You’ll be shocked and inspired by the story of the man whose vision laid the foundation for India’s digital revolution.
What is a QR Code?
A QR code (Quick Response code) is a 2D barcode that stores a variety of information—from URLs and numbers to identities and encrypted data.
Compared to traditional barcodes, QR codes can:
-
Store up to 100x more data
-
Be scanned from any angle
-
Work even if partially damaged (error correction)
-
Scan in milliseconds
They’ve become a universal digital language—used in everything from payments to identity verification.
QR Code Inventor : who is he ?
The QR code inventor is Masahiro Hara, an engineer from Japan working with Denso Wave, a subsidiary of Toyota.
Year: 1994
Problem: Slow and limited barcodes in the automobile manufacturing process.
Solution: A fast, data-rich, scannable code from all directions.
Masahiro Hara got inspired by Rubik’s Cube patterns and created the iconic black-and-white design we see today.
Why Didn’t He Patent It for Profit?
Surprisingly, although Denso Wave patented the QR code, they made it open-source.
Meaning: Anyone can use it for free, from tech giants to street vendors.
This single decision made QR codes go global.
