QR Code hung in large format over Madison Square Garden, June 2010.  Finally the "Code" is getting some traction here in the US.

Linking  the physical world with digital information is a fundamentally exciting aspect of being mobile.  Within a few short years augmented reality will become main stream as businesses begin to push new applications using a mobile device to overlay the physical world with digital information such as names of places, store info, and real-time information.  Meanwhile there is an easy link between physical and mobile and it doesn't cost anything to use it!

One very early connector of the mobile web and the physical world is the QR code.  QR stands for “quick response”.  It was developed by Japanese corporation Densu-Wave in 1994.  QR codes are very popular in Japan and by now you’ve  likely seen this square box with the black and white blocks inside, as they are used more frequently every day.  The picture at the top of this post shows a QR code prominently draped over Madison Square Garden in New York.  UPS and Fedex use them as do many manufacturers.  They simply carry much more information than an 'old time' bar code.

                              

Old Time Bar Code                            Very Smart QR Code
Not Much Information                       Contains lots of information



Basically QR codes work like this –  The phone must have QR reading software installed (takes less than a minute to install and is free).  Using the camera of the mobile device, the phone software will translate the QR code and deliver back to the user whatever you want–a mobile website, video, pricing information or actually even kick off an application like charging for a product.  

The cell phone needs a QR code reader to work, and in Japan phones come with this software already installed.  Google's mobile Android operatingsystem supports the use of QR codes by natively including the barcode scanner (ZXing) on some models.

Today MoFuse has many clients who use QR codes in interesting ways.  One publisher adds them to magazine articles to drive people from the physical pages of a publication to their mobile phone web page that carries a special offer.  Another publishes QR codes on the jackets of books and when translated, brings people to a mobile web page with more information about the author and book.

Marketers take note, when you use QR in advertising you can find out a lot about your mobile web audience.  People who translate a QR code are delivered to your mobile site - which  is fired up when the QR code is read.  Your mobile web analytics will then give you insight into who is interacting with your brand via the QR code.

If you want to try them out you can go to qrcode.mofuse.com to create your code.  Just fill in the URL that you want your customers to go to when the QR is read.  We’ll give you the 2D bar code to copy and publish anywhere.  You can also select from many sizes of QR code depending on the use.  Place the QR code on physical locations to connect people to your mobile URL.   QR is just one of many exciting mobile web tools that will help you integrate physical and mobile.
