I believe that fingerprint readers can be fooled with either a latex
impression or a dead finger.

Some devices can the cheaper ones. But why are we seucuring the door from
others is the important thing here, and it;s not like no one has ever
gained access without the correct key to any place, it;s just what effort
you need to take to eliminate such a thing and in most cases I doubt many
people carry a dead finger around with them, or have access to the latex
and a suitable finger.
Face recognicion is another option, I've heard in the USA they are looking
into guns that can only be fired after face recogniction has been used.

implementing "owner" recognition for gun triggering has been considered by
military for at least 20 years.

But only recently had the technology become cheap enough and small enough.


It all fails to solve the scenario of what happens if trouper A needs to
"borrow" the gun of (dead/incapacitated) Trooper B in hurry, in a
battlefield scenario

No it doesn't.
It just needs a little thought like dual access bank accounts.
But it does depend on what you mean by in a hurry.

I can se NO reason why a face or finger print must only be for ONE person / ONE gun.
You could have everyone in the platoon have their face recorded as ID for every gun.
At the very least you could have a 4 digit number override, and everyone in theat platoon get the 4 digit code for the day/week.
At least 5 of my friends know my 4 digit code for my ipad which is the same for my TV box.

I'm betting even harry could design a systenm where every gun can be operated by anyone with a white skin, but if someoen with a black skin picks it up it won't work.
Do you really think it's beyond us to design a gun activation systemn that can be operated by more than one face or one finger print ?


No, the real problem is designing a system that reliably can only be
operated by one face or one finger print aiui.
