For those of you who STILL think 2D codes are a geeky toy – I’ve been using a new “description” when developing marketing campaigns for clients lately;
So every movie poster, every advertisement shown on tv, every
compact disc label in a retail store should have a qr code on
it.” Want to know more? keep reading below or send me an email.
60 Second QR-codes
So What Are QR Codes? QR codes are the commercial name for a type of 2D(dimensional) bar code - as opposed to 1 dimensional barcodes which have lines running in vertical strips running in a horizontal format from left to right like the barcode you may be familiar with on a bar of chocolate in the supermarket. A 2D QR barcode has boxes running both left to right on the horizontal axis and up and down the vertical axis as well. Each small box or what we call a ‘pixel’ contains information, for example the QR code below says http://www.cognation.net/profile/index.html The 3 “big boxes” in the corners simply tell the camera which way the code is orientated, so QR codes can be snapped in any direction but generally are printed with the 2 big boxes in the top and one on the left. 
Where Did QR Codes Come From? QR codes were originally invented in Japan by Denso for industrial bar codes on packaging for warehousing and production purposes In their wisdom they realized that this “standard” would be more beneficial if everyone could use it, so they open sourced the technology and now anyone can create, read and implement QR code technology for free with no license fees being required. There have been several other 2D code technologies available over the years but all required some form of license fees as such they haven’t been widely accepted and adoption results have been disappointing.
How Did QR Codes End Up On My Phone? In the 90’s the use of QR codes were rapidly changed by all of the Japanese mobile carriers sitting down and agreeing to implement QR software into their mobile phones. Originally it was just a concept for delivering business card information. For example the QR code below has a VCF card with my name, phone number, company name and email address. This is a highly efficient way to ‘store’ this information and by printing this 2-d image on the back of your business card allowed for very rapid deployment of information transfer into your electronic address book both on the phone and your desktop.
In the USA it is very disappointing that most carriers have tried to 'milk money' out of their customers and gone for 'proprietary bar code' systems so they can charge clients for reading codes and publishers for printing codes. This is why the 2D bar code system here in the USA is so flawed - greed.
It's a shame
considering the inventors of QR codes, Denso, were so visionary to
let anyone use their codes for free that people are now trying to
stand on their shoulders and rip people off. QR codes can be created
by anyone license free and most readers can be downloaded to any
camera enabled smart phone for free.
QR codes can be
read by almost any phone with a camera. Remember any QR code can be read by any reader. There are some variations on functionality but this is outside the scope of this overview. QR Codes can be implemented to do the following;
e.g. Message:

e.g. “Iron Man 2” QR movie poster campaign which had a QR code to access the movie's mobile site including trailers and interviews to be directly played on your mobile handset while in the cinema foyer.
