it is surely interesting though i am curious to know how accurate it is and how many bugs it has. for example whath appens if you grow facial hair like a mustache or a full beard, will you lose access to your money 
Hahaha this. They'd have to do a lot better than Apple's iOS face recognition(Face ID). While this was definitely last year and that apple's Face ID most likely has improved and maybe fixed this problem already, I had a mutual friend that had a very very identical twin(pretty much their hair bangs is the only noticeable facial difference between the twins), and the twin could unlock the phone with no problem at all.
