QR / 2D Code

QR and 2D codes were born in Japan

The QR Code is a matrix 2D code invented in 1994 by the development division (now spun off as Denso Wave) of Denso Corporation (Aichi Prefecture), an automobile parts manufacturer.

 "QR" is an acronym for "Quick Response," a name that is intended for high-speed reading as one of its purposes. "QR Code" is a registered trademark of DENSO WAVE (No. 4075066).

Today, not a day goes by that we don't see a QR (two-dimensional code). What did you think when you first saw QR codes? I was used to seeing barcodes, but the design of the QR code, which is a square frame with swirls, squares, etc., in various places, made me think, "What's this? What is this? Many of you must have thought that your eyes would roll back in your head.


Why QR and 2D codes have spread around the world

As described above, Denso Wave Inc. has obtained a patent for QR Code. However, since no patent royalty fee is charged, no permission or contract with the patent holder is required when companies want to use the QR Code, which seems to mean that the QR Code has spread not only in Japan but also throughout the world. The advent of QR (two-dimensional code) has made our lives more convenient. I would like to thank DENSO WAVE INCORPORATED for spreading Japanese technology to the world.


Why QR and 2D codes are useful

QR stands for "Quick Response," which can be translated as "quick response.


By reading this QR (two-dimensional code) with a smart phone, you can obtain a large amount of various information. It's instant and speedy!

It is no exaggeration to say that it is now attached to all kinds of things.


It is often attached to paper media. There is a limit to the amount of information that can be sent out on a given paper size; if QR (two-dimensional code) is printed, a much larger amount of information can be provided.


It is often found in supermarkets. You can also find them on price lists and pop-ups.

It is also listed on the products sold, and detailed information about the producer, cooking method, and even the manufacturing company can be found through QR.


Recently, it has become familiar for its use in electronic payments.


It is also useful for account exchange and registration on social networking sites, etc.


QR (two-dimensional) codes are now displayed on TV screens, and the announcer announces, "Please read the QR code on the screen," to get more detailed information.


 Since a few years ago, QR codes have become a common sight at tourist attractions. Even if you don't have a guidebook, you can scan the QR (two-dimensional code) and get tourist information.


Multilingual QR and 2D codes

The use of QR (two-dimensional) codes in tourist attractions is effective. When Tokyo was chosen to host the 2020 Olympic and Paralympic Games, and with the increase in the number of tourists visiting Japan, QR (two-dimensional) codes were introduced to provide multilingual foreign language guidance. I thought this was a revolutionary invention.

Foreign visitors to Japan have the advantage of being able to freely tour tourist attractions without an interpreter-guide, while obtaining accurate information on the history of the destination.


PIJIN Corporation developed such a convenient, multilingual, QR (two-dimensional code).

By simply reading the QR (two-dimensional code), the system displays the information according to the language of the smartphone you are using.


 You can see them not only at tourist attractions, but also at public facilities, shrines, and temples.

It is also attached to packages of high-end sweets, etc., and is convenient and reassuring for foreigners visiting Japan, as they can "know in their own language" what ingredients are used, where in Japan they are made, what the name of the store where they are made is, and so on.

On the other hand, stores that provide QR (or adopt QR) also have the advantage of being understood and remembered in their own language.


 If you look at the design, you will say, "I have seen that before! and it seems to be integrated into daily life these days.
