alt Hacker NewsNever thought about this before but we already have biometric scanners on our phones we rely on and work quite well, why couldn’t it work for guns?

They exist. For example, https://smartgun.com/technology and digging into the specs ... https://smartgun.com/tech-specs
Facial recognition: 3D Infrared
Fingerprint: CapacitiveI had a fingerprint scanner on an old phone and it would fail if there was a tiny amount of dirt or liquid on my finger or on the scanner. It's not big deal to have it fail on a phone, it's just a few seconds of inconvenience putting in a passcode instead. On a firearm, that's a critical safety defect. When it comes to safe storage, there are plenty of better options like a safe, a cable/trigger lock, or for carrying, a retention holster (standard for law enforcement).
If the biometric scanner stops you from shooting a target that someone else other than you determined?
You’ve never had your fingerprint scanner fail because your hand is dirty?
Or you didn’t press it in the right spot?
Or the battery was dead?
If I’m out in the wild and in a situation where a bear is coming my way (actual situation that requires carrying a gun in certain locations) I do not want a fingerprint scanner deciding if I can or cannot use the gun. This is the kind of idea that only makes sense to people who have no familiarity with the real world use cases.
