from biometricupdate.com: A young inventor in Boulder, Colorado will receive a $50,000 grant from the Smart Tech Challenges Foundation to continue working on a biometric sensor that prevents unauthorized individuals from firing a weapon.


Kai Kloepfer, a high school student from Boulder, Colorado, is the
first benefactor of the $1 million Smart Tech for Firearms Challenge,
which will award grants to a total of 15 innovators “who are working to
improve firearm safety by developing personalization features in
firearms, locking devices, and ammunition systems,” the foundation said
in a release.


Kloepfer, 17, first developed the sensor on a plastic model of a Beretta Px4 for less than $3,000.

Using stored fingerprints, the sensor enables authorized users who
are holding a gun to activate the trigger, while those users who are
unauthorized will not be able to fire the weapon. In Kloepfer’s tests, the sensor prototype successfully worked 99.99 percent of the time.
