Last night I had a dream of this invention, that I thought was pretty cool. The last time I thought of a cool invention, it didn't get too many raves: A clear see through toilet for locating clogs.
It took me two hours to get back to sleep cause I was thinking about some details of implementing it. But I have no background in firearms, or in fingerprint identification software.
Anyway, it looks like someone else already thought of it. Sure would be nice if this was something out on the market. My biggest reason for NOT buying a handgun is that it could get into the wrong hands, but with the fingerprint scanner on the gun itself, that would eliminate any disasters.
Cops would love this cause it would prevent someone taking their gun and using on anyone else. It would also help in solving murders. It would help with little kids finding a gun and using it accidentally to kill their friends or themselves. Also if the gun was more digital in that for every round fired, it left a digital fingerprint on the casing and slug, logged the time it was fired, the direction it went and the fingerprint used to fire it. All this info uploaded automatically (the gun would also need to have wireless service integrated into it) to a server instead of on a chip on the gun, which could be hidden or destroyed. Also when the gun is fired without calling a service number, then the service center that logs the firing of the gun, would call 911 which would include the location of the gun and all the other data.
The cost of the gun would probably be 2 - 3 times what a normal handgun would be, but would have so many protections built in, that it would be worth it.
