A po�ed history of 2D barcode technology
T
e
In terms of the history of 2D barcodes, we have to travel to Japan around 7 years ago. The Japanese
were the pioneers in making the barcodes readable via the mobile phone. 2D barcodes are now
very ubiquitous in Japan. Denso Wave was the company that started the whole revolu�on in
developing the original 2D code.
Japan went with QR codes as they are able to hold more informa�on than other compe�ng 2D
barcode standards but as such they are correspondingly bigger, 60% bigger than a Data matrix
code. In Japan, the speed of development in 2D Barcodes was driven by the fact that the Japanese
government in associa�on with Japan’s largest mobile operator (NTT Docomo) effec�vely
monopolised the market by building QR code readers into every single phone they released.
They did this by including a magnifying lens into the phone so that the size of the QR could be
shrunk and s�ll read. This created a lot of trac�on for the rollout of 2D barcodes in Japan. So on the
basis of this, around 75% - 80% of Asia are using this system which is built around decoding to URLs
(Source: UpCode Solu�ons).
The success of the QR code in Japan was in many ways also its limita�on. Due to the satura�on of
this type of 2D barcode system it has meant that in order to build in more sophis�cated func�onality,
they really have to go back and reprogram all the phones again, which is not ideal…. QR codes are
the most ubiquitous of the 2D barcode technologies but they are not necessarily the best op�on.
It really depends on your individual needs and goals as a company. People s�ll tend to call all the
different types of 2D barcodes QR codes when in fact they are not.
The different types of 2D Barcodes
2D barcodes have a number of itera�ons and can be used for a number of uses.
In Japan, they use a par�cular type of 2D barcode known as the QR code, which looks like this, with
three square iden�fiers:
QR Code
This however is only one type of 2D barcode.
