DNP Develops DC-Code, Invisible QR-Code Alternative

Dai Nippon Printing(DNP), the world’s largest printing firm released a free Android app which works with DC Code, which is like popular 2D barcode “QR code” but invisible.

The app instruction is like this,

(1) download app by searching “QUEMA” on Android Market
(2) run the app
(3) hold up your Android over the printings which have digital watermark
(4) related contents (video for example) will be played from your code

DNP named the system using DC Code and smratphone reader app as QUEMA(QUick and Easy Media Access).

Agreed that QR Codes on posters and magazines take some spaces, and that may be annoying for people who do not use QR Code. However, if it is invisible how can people notice that the code is there? Actually, touch-less radio-communication system like NFC has the same problem when you try to use it like QR Code.

Japan’s Prime Ministar Begins Blog

Naoto Kan, Japan’s 94th prime minster who took the position this June, enters into the web by his new blog yesterday, November 18th.

The blog, named “Kan-full Blog” [J] after his sirname “Kan” and an English word “full”, which shows his full efforts on communication, also has a pun meaning “camphor” to inject for “revitalizing Japan”, as explained on the blog’s sidebar.

On the first post, the author, who is not Mr. Kan himself (clear by how the writing handle the name and the title), explains it is going to have three categories of posts.

Kan-full TV
Posts featuring movie which is either “interview of the PM” or his address/speech. Staff will find his odd minutes between busy works and take his fresh voices.
Ippo Ippo(step by step)
Daily report of his activities. Meant to be an index to the detailed political resources on all government ministries and agencies websites.
Kantei Zakkichou(The prime minister’s office notebook)
PM’s office staff and others will report the prime minister as they see.

So it is not direct speech by Kan himself, but by his team.

Interactivity and social aspects

It is nothing strange as Japanese politician’s blog, there are no comments or trackback systems offered on each blog post. There is a feedback form, on which you may send his/her opinions, suggestions, etc. Your gender, age (from 0 to “over 100”) and prefecture(or “oversea”) are asked but not mandatory.

For a notification, you can choose from RSS1.0, RSS2.0 or e-mail.

Mobile version is guided by both URL and QR Code. The blog name is embedded at the centre of the QR Code, which is a gimmick using the bar code’s error correction ability.

The blog article has three icons, linked to Google Bookmarks, Hatena Bookmark and Delicious Bookmarks. Hatena’s one is the most popular one in Japan, but others are not so popular than non-listed ones like Yahoo! Japan Bookmark, Buzzurl or Livedoor Clip.

There are no Mixi Check, Twitter or Facebook Like buttons.

Opening trouble

The blog’s URL had been reported on some Japanese media in morning 18th, however, when you tried to access it, you were asked to type user name and password by a dialog box (basic authentication dialog) until the evening, around 18:00.

The former prime minister Yukio Hatoyama, who is pretty unpopular now, ran Twitter and once got the most followed Japanese Twitter user title.

According to Asahi Shimbun, Kan did not continue the prime minister’s e-mail newsletter, which had been kept by recent several PMs for years.

QR Code Blog – Written Only In QR Code

QR Code seems getting popularity in West because of smartphone. There are a lot of interesting ad campaigns utilizing QR Code recently in English.

There was also a news that Google’s URL shortening service goo.gl supported QR code generation, then Bit.ly followed the trend this week.

Some of you might know that QR Code marketing were often quoted with “only in Japan” for years. And this is one of the unique thing you may reproduce in your language when your people want to know more and more about QR Code.

It is the QR Code Blog. It is not a blog about QR Code, but a blog all written in QR Code.

You know that QR Code can convey URL and/or mail address, but in reality, a QR Code can include about 4,300 roman alphabets, or about 1,800 Japanese characters (size of the code will be big, and error correcting capacity makes the maximum number smaller). So this person embed his article on the code(s) and published as “the world most unreadable blog” he said.

The blog started in September 16th, 2004 with this,

If you scan it (by Android/iPhone app for example), that will give you Japanese text, which tells,

I am trying to build a blog using QR Code. Please enjoy this inconvenient blog both for a writer and readers. It will be good if I can post every day.

Two and a half years later, the blog ceased at the end of 2006. Probably because QR code became too common and the blog could not expect further attention. On the last post, the author wrote long article with 5 QR Codes,

I double translate them from Code to Japanese to English,

Long time no see. How have you been doing? Time flied in 2006. Sorry I did not post since September. I apologize.

I began this blog in September 2004. It was the time when I was finally seeing real usage examples of QR Code. Now two years passed since I set up this blog with the motivation to pass on the wonderfulness of QR Code to many people, the situation around QR Code has changed significantly.

Now QR Code is recognized widely, used on food, magazine, outdoor advertising, name card, etc. Now QR Code reader function on cellphone becomes commonplace. Are you seeing much more QR Code recently?

In last two years, this blog has been taken up on a lot of websites, magazines and TV programs. I can not know how much I could contribute on spreading QR Code to be recognized precisely, but if I made some help, that will be my great pleasure.

http://(Akky: seems his encoding mistake)As seeing QR Code widely prevalent, I think this blog has completed its role. I today declare the end of this blog. I really appreciate you all readers who scanned and decode this blog with your cellphone or so. Thank you so much.


The World Biggest QR Code By Audi Japan Employees

I found this on YouTube, Audi Japan and its sales subsidiary Audi Japan Sales‘s making movie of a huge QR code in gymnasium.

According to Nikkan Jidousha Shimbun [J], this was made in July 2009.

I could read the QR code on the movie with my Android phone with Barcode Scanner app. The code points http://audi.jp/qr , which does not respond. It is too early to finish your campaign site.

There have been many huge QR code ads are all around Japan for 4-5 years.

Here is a 9 meter squares QR code appeared [J] on the building wall in Tachikawa, Tokyo in November 2009. (photo by Asahi Shimbun)

You may see another one in Ginza, the high street in Tokyo (photo by malpocha).

At Shibuya 109 shopping building’s wall (photo by Barks),

Another one in Shibuya (by obanajun),

In Akihabara, of course. This one was by Disney Channel reported by Akibamap.info

Northwest Airline put their bug QR code ad on Shinjyuku building in 2005 (photo by Nikkei Media Lab).

Shinbashi building shows mobile online loan ad.

In Fukuoka, Kyushu,


The first huge QR Code claiming the world record was in 2006 in Hiroshima [J], on the wall of apartment building under construction. Advertisement by the constructor.

You may check more QR code samples in usage on Asiajin.

[Update 2010-01-05]

Blog 2d code told us that the one displayed on the big screen at Cowboys Stadium, Texas, USA might be the current largest. Thanks Roger.

[Update2 2010-01-05]

We also got a message from Audi Japan’s twitter account @AudiJapan.

@asiajin Thanks for the QR code article. Ours was 12x12m, done at Makuhari, and it looks bigger than Dallas Cowboys.

Hmm. Which is bigger do you think? Theoretically projecting on screen can be easily bigger but the one at the Cowboys Stadium seems not to utilize its maximum potential. Both are interesting but I salute to Audi Japan’s as it involves a lot of people and hard work.
