I belong to those who claim to "not really know their way around technology". It is therefore important to me that complex processes are presented in an understandable and simple way. What fascinates me about Smart Lock technology is the fact that it not only replaces the key - the central element of a home - but also extends it. An innovation for everyone, not just for techies.
