Fingerprint Smart Gun

Kai Kloepfer, a 19-year-old from Boulder, Colorado, lives about 35-miles from the Aurora movie theater shooting that killed 12 people, an event that inspired him to develop a fingerprint-activated gun. This smart gun uses biometric and encryption technology to only activate when in contact with the right fingerprint. “When the owner picks it up, or somebody the owner has chosen, the gun will work for them. But if a child finds it, a teenager tries to use it to commit suicide, or even if…an assailant disarms a police officer, then the gun is locked and unable to be used,” said Kloepfer.
