Harzdrenalin is a unique leisure experience that opened in 2017 at Rapbodetal Dam in the Harz mountains. 120 m above the chasm of the dam, visitors will find one of the largest and longest ziplines in Europe. Another attraction at Harzdrenalin is the 483 m long suspension bridge that offers a splendid view over the area. As the bridge can only be accessed by a limited number of visitors at a time, reliable admission control is essential. To be able to handle the massive rush of visitors at peak times, the team of Harzdrenalin relies on Fischer's ticket machines and access control terminals.
