21. Armatix Smart Pistol
While huge devices are always impressive, we must not forget about small ones that can be handy in delicate situations where you must be stealthy. This pistol looks like it was created as a movie prop, but it actually exists!
It’s a .22 calibre pistol that can only be fired by the authorized user that wears the accompanying smartwatch – which gives other essential information – battery charge of the gun, precise time and data, number of shots fired and the timeframe of the shots!
