The tenth anniversary is an occasion for a world premiere. The Reeperbahn Festival Logbuch (logbook) provides our visitors with a completely new user service. Via smartphone you can track the events visited the night before, offering exclusive additional contents: Recordings of visited shows, acoustic versions, keynote interviews, sessions and much more. The 'Logbuch' works on a network of iBeacons, reaching across all Reeperbahn Festival locations. Its application is very straightforward: On activating the Bluetooth function the Reeperbahn Festival locations visited will be stored on your smartphone (and only there!). It enables you to look up the name of the stunning band, for example. A model acting as a precedent all over the world? - As it is an absolute pilot project first results will be presented at the conference programme.
