The more I read about Quick Response Codes (QR Codes) the more I see the future of marketing: a true interaction between consumer and marketer. Users able to to scan and get more information simply by scanning a code in a magazine or a billboard. Applications available to help users integrate a new product or service into their daily lives.
QR also brings in scary thoughts of dystopian futures where advertisers and governments know your every move. The technology that can bring a cornucopia of products can also bring in 1984 type surveillance.
Still - the future benefits are evident. QR Codes are easy to create and simple to display. Their uses run from the mundane such as quickly sending users to a website (or a subsection thereof) or providing them with up to the minute promotions. But there are more interesting uses such as stores luring consumers in based upon their buying habits; or by integrating a product with an existing app to give an unintended outcome. For instance you're in the supermarket and pass a product. Your recipe creation app has interfaced with your going out app and "concludes" that you are in the mood for Indian food. A voice or text message appears: "Buy this product and that one over there. Add it a your existing foods and you will have an excellent XYZ meal for your hot date tonight."
Oh, the future is bright. Where are my shades?
