Several companies have come to SHOT Show in the past several years, advertising that they have figured out how to make smartguns 100% reliable in a self defense situation, but after testing, the technology is nowhere near as foolproof as they claim.
Armatix’s iP1 pistol, is one of them, a smart gun that requires a radio-frequency-emitting watch to operate. Sure, it’s prohibitively expensive at $1,800, but from the looks of things it is rather reliable — so long as you remember to where your watch! The watch/ring/band RFID concept has been tried before, and it’s really a joke.
What about a year later when you can buy RFID gun jammers on Ebay?
