There’s a crowdfunding project here: http://www.indiegogo.com/projects/fund-safe-guns that is for the creation of smart gun development. Basically, the government’s new proposed gun control method is bio-metrics on guns.
I’m not going into politics or my point of view on gun control, but I don’t see how this is going to make things better. The idea itself is interesting and better than RFID (I can’t see someone having to wave a RFID card at their gun to fire), but it doesn’t solve the issue of who fired the bullet. It only reduces the chance of the gun being used by someone other than its owner.
