I am pretty sure that’s not how they work.
I know that when I am trying to get into my cel phone there are times I have to try three or four times. I am sure my fingers will be sweating a little more if I was pulling out a handgun.
I tried the fingerprint reader on my Galaxy S6 as a means of securing the phone. Bad idea. Fortunately, they insist on providing a password as backup. I needed it. The fingerprint reader approach is once again disabled on my phone.
There is no way I would accept that kind of technology as barrier to use of my property (firearm). I'm sticking with my old, reliable technology. It's safe in my hands and works when I need it without a defective technology barrier that would certainly get me killed.
