There are at least a half dozen smart guns in development right now.

The guns have technology that is designed to fire only if matched to an authorized user via fingerprints or other methods.

"Cyber Guy" Kurt Knutsson tested a new line of smart guns that unlocks when the user wears a special ring or watch.

The gun wouldn't fire when he didn't wear the ring.

Developer Jonathan Mossberg allayed concerns that the government or hackers could try to take control of the guns through this technology.

He said his technology doesn't operate over Wi-Fi, but over a signal that's an inch or so in range.

Time will tell if the technology catches on. What do you think?
