esigner Jess Han has re-imagined the simple door handle with a DaVinci Code style lock that denies entry for all but the chosen few. This intuitive door handle dubbed the “NUMLOCK HANDLE” features a numbered dial-lock that re-shuffles and locks itself after every successful entry.   The numbers can be replaced or supplemented with braille for that extra level of mystery. We find this idea atractive and we are so sure that soon an intelligent company will contact Han and produce this great idea. We will keep you informed!
