An Amsterdam Security Story...
The electronic locking systems by Uhlmann & Zacher are not only suitable for
big industrial plants, universities or airports. Also smaller objects can be perfectly fitted with a digital system. The company Rubinstein in the Netherlands did so.

The publishing company Rubinstein B.V. is situated in the heart of Amsterdam. They publish both books and audiobooks for adults and children and also produce their own audiobooks for children. The company is involved in film and theater productions, too.
They use the system Clex private mobile for three doors in total. There are Electronic Door Handles Outdoor in use. One Electronic Door Handle is used in the entrance door of the owner’s house, Mr. Rubinstein. One Door Handle is for his garage and one for his office.
With Clex private mobile, users of the system can manage their electronic locking units, for example electronic door handles and cylinders, as well as open and close them. In the process, the smartphone communicates with the locking units via Bluetooth® Low Energy. Alternatively, opening and closing is also possible using RFID transponder. In addition to private homes and smaller offices, the system is also ideal for doctor's offices and law firms.
The management is easy and convenient using the Keyng App. The smart navigation guides the managing person through the app and always provides a clear overview of all the transponders and smartphones. Functions such as disassembly, battery replacement or service opening are also possible in the app. It is easily possible to manage access to different kind of doors.
The end users use the Clex Key App to open and close the electronic locking units. Thereby the smartphone does not have to be connected to the internet. This is advantageous, for example, for doors in underground car parks or similar environments.
About 20 persons have permission to the office door. The employees use a transponder fob or a transponder card. The managing director, Mr. Rubinstein, uses the app to open and close the door. One of his employees manages the locking system via his smartphone. With the system Clex private mobile, he can easily grant and revoke user authorizations. Another reason was important to Mr. Rubinstein: Due to his multiple sclerosis, using a mechanical key was becoming increasingly difficult for him. The use of the digital transponder was a great facilitation. Mr. Rubinstein with regard to the electronic locking system: „We are very happy with the locking system, because it makes the door management a lot easier.“
