Fully loaded with shopping bags – in this situation, many of us appreciate not having to search for the key on the doorstep. Here the keyless entry system for apartment buildings of the Berlin Startup KIWI.KI helps. According to the principle of KeylessGo systems for cars, the door can be unlocked via a contactless radio sensor in the door with a transponder in your pocket. With an additional app, it is even possible to open the door with your smartphone.
How do we have to design the app to meet all possible usage requirements – for example when craftsmen need to have access at a certain time? We need to enable an interaction between the user and the system that ensures a comfortable and safe operation of the app.
We develop a redesign based on the results of usability testing:
+ Optimised and intuitive navigation
+ Personalised and time-limited access, e. g. for craftsmen and postmen
+ Increased security and confidence in the system
