This was by no means discouragement of their use. The 'Quick Response' codes offer a speedy direct line of communication between a business and the code scanner. More sophisticated than a bar code, QR codes can hold geo co-ordinates, URLs and business information that can be transported into mobile phone contacts and memory. This is particularly handy on business cards.
And they are simple!
iGoogle offers an excellent QR code generator. Once the generator is set up through iGoogle, you will have a "tool that allows you to generate QR-Codes from URLs, messages, phone numbers, SMS and pre-written emails."
The codes can be used to detail events and promotions, product information and provide coupons. A potential customer can scan a coded product and find out where they are available for purchase. Clever use would have people directed to updated sites and social media pages to improve awareness.
In addition, when they are added to a website they can improve SEO results. Placing a QR code onto a website is an excellent way to ensure updates and get Google indexing site information. The QR code will be indexed as an image. This may have two very positive effects. Google may recognise the image as QR code and the information it holds may be indexed.
