It's like something out a Bond movie — a gun that will only fire for one specific person. The Armatix Firearm Smart System makes it a reality. This unique system pairs an .22 calibre iP1 pistol with the iW1 RFID watch, making it so that only someone wearing the watch can fire the weapon. The gun automatically deactivates when it loses contact with the watch, and the watch itself lets you enter a pin code to release the safety, adding yet another measure of security. After all, when it comes to firearms, you can't be too careful.
