As an active international, entrepreneurial team, we are working in the field of digital cryptographic lock systems. Our vision is to simply authorize locking by an electronic mobile device, such as a smartphone, and to become the market leader for the administration and the sales of digital keys. A key could never get lost or forgotten anymore as it is conveniently saved at the mobile device and the data can easily be shared with another electronic mobile gadget. Our purpose is to develop a smart mobile lock, which is able to open and close by a short range wireless connection, controlled by a smartphone app (Android, iOS). During the last year we already made some first hardware studies and tested a first concept, which is potentially patentable.
