This poster, found in the student quarter around Ipswich Docks in the UK, highlights how knowledge of your target audience can refine mobile usability. It is designed specifically for the significant number of students equipped with Blackberries. The QR code links directly to Blackberry Messenger, the student messaging platform of choice, adding the event organiser as a BBM contact. It is convenient for the users and helps the promoter add subscribers to their list.

It is the first example I’ve seen of a QR code linking direct to BBM.
