Firearms & knives

In most cases, guns are stored inside a safe that can be biometrically protected.

Some specific safes also exist, mainly holsters.

But it is also possible to directly protect the use of the gun itself, either with an integrated protection, or an add-on to lock the trigger.

See also the grip recognition modality, where some research is done especially for guns.

Ammonition may be directly protected (not the gun itself).
