Key-Less-Locking Mechanism
Knollan is a startup company that has completed the development of a very innovative locking mechanism. This mechanism is suitable for all kinds of locks, and for any security level, while offering many additional advantages over existing locks. The Knollan mechanism resembles the idea of a combination lock, but it is unique and entirely different from any existing locking device. It has many special features that lead to commercial strengths, if not market superiority, over existing locking mechanism.
