I don't know they've been talking about smart guns technology for a long time now the biggest problem with them is price and them actually working in a crisis situation.... Firstly my finger is my safety along with the one that is already on the pistol or rifle. it's not a matter of reinventing the wheel it's a matter of just education of the general public in safe ways to store your firearms, it's a no brainer unless you're brainless and if the latter is the case you probably shouldn't own a gun.
