A QR code (quick response) is one of the latest tools to connect offline people with an online service or information not ordinarily available to them at that time. A QR code is generated through any one of many sites available online, and can be directed to any of the following:
Website - for a competition, free tools, further information on a service or product
Text information - a pdf which provides product support
Video - direct link straight to a promotional or informative video
Directions - google maps
ME card - enables the receiver to scan and have a contact's details sent directly to an android phone
Print media and direct mail - to direct to another site such as a company or individual's social media sites
That's the background, but worthy of a mention is the possibility of customising a QR code to make it fit with a corporate colour, further promote a business and make it more of a visual tool rather than a functional one.
This is our ME card which we think looks much better than the stark black and white traditional QR Codes. Using photoshop to edit the original QR code means it is possible to add an image to the code without compromising the structure of the code itself.
As well as adding an image to the centre of the qr code and a different background .........
.........it is possible to add a png logo or even change the qr code colour completely

Hats off to freeqrcodetracker.com, a Bournemouth and Poole based company for a fantastic service and informative site. We started using them for qr code generating recently and are very impressed with the service, especially the hand delivered promo gift and goodies for me, the personal touch is always great.
