The inventor of the QR Code®

The QR Code®, a success story that has no equal. Where would we be without it today? Where would logistics, field service, advertising, and, all in all, mobile data processing be? It has never before been possible to combine as much information cleverly in one digitally readable code. "QR" thus became the synonym for efficient data information.

In 1994 Masahiro Hara and his team invented a product that is made up of little dots. It was supposed to go around the world and make a lot of things faster, better, and more detailed – and all that with one scan that takes only a few milliseconds.

In the years that followed, various versions of the QR Code® were developed so they could meet certain needs in particular areas of application. The Micro QR Code is particularly small, the iQR Code can be generated with either square modules or rectangular ones, and the SQRC® can even include secure, private information only readable for a selected audience. With the LogoQ, it is even possible to integrate your company logo into the QR Code. We are curious, which great new types of codes our colleagues are going to come up with in the future.

Model 1 is the original QR Code®. The largest version of this code is 14 (73 x 73 modules), which is capable of storing up to 1,167 numerals.
Model 2 is an improvement on Model 1 with the largest version being 40 (177 x 177 modules), which is capable of storing up to 7,089 numerals. Today, the term QR Code® usually refers to this type.

More Information

Only one orientation detecting pattern is required for this code, making it possible to print it in a smaller space than before.
This code can be viable even if the width of its margin is 2 module-worth (QR Code requires a margin of 4 module-worth at least around it). The largest version of this code is M4 (17 x 17 modules), which can store up to 35 numerals.

More Information

Code that can be generated with either square modules or rectangular ones. Can be printed as a turned-over code, black-and-white inversion code or dot pattern code (direct part marking). The maximum version can theoretically be 61 (422 x 422 modules), which can store about 40,000 numerals.

More Information

QR Code® that has a reading restricting function. Can be used to store private information or manage a company's internal information.
Its appearance is no different from the regular QR Code®.

More Information

FrameQR is a QR Code® with a „canvas area“ that can be flexibly used. Since letters and images can be inserted inside the canvas area, the FrameQR can be used for promotion, authenticity judgment, and other various uses.

More Information

The FrameQR-K combines a QR Code® with a FrameQR®: The QR Code® is integrated into the upper left corner of the FrameQR®. If the FrameQR-K is scanned with a general QR Code Reader, only the QR Code® is captured what leads to the download of DENSO WAVE’s Q-Reader app. When you use this app to scan the FrameQR-K anew, only the FrameQR® is captured.

And the winner is:
Masahiro Hara - Inventor of the QR Code®

In 2014, the year of the 20th anniversary of the invention of the QR Code®, Mister Hara was honored in the name of his team. He received an outstanding award for this small but brilliant invention, the audience award of the European Patent Office. As there were 15 nominees altogether, it seems almost incredible that the QR Code® received 30 % of the votes. That is an impressive proof of how much people already love and appreciate it.
