Our History

1990   

The business idea of developing complete software solutions for the hotel industry is born in the owner-run hotel of the Uhlmann family. Uhlmann & Zacher GmbH is established by Martin Uhlmann and Dr. Marc Zacher.
In the following years, Uhlmann & Zacher provides systems for the hotel industry: from the management program and inventory management to POS software including PABX management.


1996 

Martin Uhlmann‘s father, Günter Uhlmann, invents the electronic cylinder. Uhlmann & Zacher develops software for simple locking systems. This segment becomes the second pillar for the upcoming company.

Carl H. Scheuermann joins the company and is since then responsible for development.


1999   

The German Patent DE19603320 is issued for the electronic locking cylinder with centrifugal engagement.
