Recently we've been involved in a project to help the students know the timetables of the classrooms in situ and other info on other university services. We decided to put a QR code for each item (classroom, library, secretary, service, etc.) with and url encoded. This url redirects the petition to a proxy web application that depending on the type of the item shows a mobile adapted web site. For example, if a student scans a QR code placed in a classroom, the web shown will display the timetable of that classroom. Another example could be scanning the QR code of the university restaurant. It could display the timetable and the menu for that day. This method can be applied to many purposes and it's easy to generate QR codes and put them in whatever you want.
