This project was developed in the summer term 2011 by Simon Ihlenfeldt, Alexander Martin, Steffen Mohring and Lars Peipmann. It allows you to shop using a QR-Code Scanner. When you scan a product, it will add it to your shopping list. The software was developed as an hybrid Android application using HTML5 for the fronted and including an own JavaScript interface for communication with a native Android QR-Code scanner component. The application can automatically detect the location of the user, providing a location based shopping facility. That is, the application changes its user interface based on the current user location. Nice idea!
