A gun with the “smart” technology would sense the gun owner’s biometrics and grip pattern, allowing only the registered gun owner to operate the weapon. Similar devices, such as RFID chips and magnetic rings, are both available and under development.

However, Nick Bilton, technology reporter for The New York Times’ technology blog “Bits,” wrote Wednesday that weapons featuring the biometric technology are hard to find in stores, because demand is low.

“No one thinks a smart gun will stop a determined killer,” Bilton said.
