What specific case are you afraid of? You are outside in the wintertime with a gun concealed on your person, and a would-be assailant comes along? Then get the kind that uses a ring, not a fingerprint.

And when you lose the ring, get a new one immediately instead of waiting for the would-be assailant to come along.

Among the questions I have from the article:

* What is the ring/watch material made of? How durable is it.

* For the "smart ring", can I get this sized-to-fit?

* What exactly is powering this scanner? What happens without power?

These are just concerns off the top of my head; I'm sure there are other concerns I'm not thinking of. Should my fob become damaged/dislodged in a scuffle what happens then? With a firearm, what you don't want is fragility.

I don't know personally, but presumably companies designing these guns have thought of the same concerns and made the rings to be durable and sizable.

Re battery dying - if I was designing a smart gun, I would have it default to a regular, usable-by-anyone gun if the power dies. That way you don't have to worry about mastermind criminals with EMP devices either.
