Smart-handgun only fires when in proximity to special wristwatch

The Armatix iP1 is a handgun that is only capable of firing when in range of the included waterproof wristwatch. Utilizing a RFID chip with a proximity of about ten inches, a light just above the grip will turn green when the gun is ready to fire. When the watch is more than ten inches away from the pistol, the light on the handgun will turn red and nothing will happen when the trigger is pulled.
