A “QR code” (Quick Response code) is a form of two dimensional code gaining popularity on the internet but was initially designed for the automotive industry (think bar code on steroids). Their popularity has increased recently because lots of people (possibly a narrow majority) now have a Smart Phone in their pocket and this has had a neat bar code reader incorporated into it in the form of an App! Initially the iPhone was the forerunner but now Smart Phone having a variety of operating systems have had a reader App developed for them.
When you use a Smart Phone there are a few big drawbacks. The screen is quite tiny and has a matching keyboard so typing in a web site is particularly difficuly even for those with 20 20 vision and 100% dexterity. What we need is a point and shoot device that generates the URL for us and sticks it in the browser. That’s what your QR code app does for you. Take a picture of the Code displayed out side your local Tesco and no matter how complex the URL is you end up going there once the ‘scanner’ in the phone has done its decoding.
QR codes are beginning to be seen everywhere, billboards, magazines and business cards. The code is made up of black modules arranged within a square pattern on a white background and can contain virtually any kind of data. (it doesn’t have to be a web site address it could be a full prodcut description etc)
The Code Block might vary in size (width and height) to match the application that it is being used for.
How could these codes be used?
The codes can be used in several ways. I have used them for incorporating contact details into business cards which could then be easily scanned by most up-to-date smart phones when using the appropriate app.
A major project devised for a Client was where we embedded the QR code information with his website address. The browser on the Smart Phone automatically directed to the website. On the way to the website our server records information so that we find out what particular code was applied thus providing the Client with valuable tracking statistics.
QR codes can be placed onto just about any object and can be scanned straight off of TV’s, Pc monitors etc. A walk round my local town center revealed lots of A2 size posters in shop windows that took people with Smart Phones to a further description on the web.
