An example of a permanent safe
Gun safes can help restrict access to a handgun. To access the safe, the owner will need to insert a physical key, input a code or combination, or provide his or her fingerprints. Gun safes can be permanent, semi-permanent, or portable.

Biometric Lock
- A biometric lock requires the owner to use his or her fingerprints to unlock the device. The lock can be coded for multiple authorized people.
