Biofire, which began as a high school science project in 2012, claims to have created the world’s first operational biometric smart pistol. To unlock and shoot, facial recognition and fingerprint verification are required. Pre-orders are presently being accepted by the company.
“The basic premise of a smart gun — a firearm that only works for you — is sort of obvious and uncontroversial,” Kloepfer explained to NPR. “The difficulty is that no one has ever built one that always works for you and never works for anyone else.”
The smart gun from Biofire is a handgun with a small fingerprint sensor on the handle and a 3-D facial recognition sensor on the back. When a person authorized to use the weapon picks it up, it lights up green and switches on. It turns off when they set it down. The gun will not discharge if anyone else picks it up.
