Biometric safes use a lock system which implements biometric technology in identifying authorized users. Safes can be entirely biometric in some cases. Biometric locks can also be used together with a combination lock, card swiper or a key for extra safety. The reason why people prefer using biometric safes is that it increases security and makes the safe ideal for locking away precious items.
The biometric technology implements distinctive human traits as identifiers. Facial scans, DNA testing, finger prints and retina scans can be used as biometric identifiers. Fingerprint scans are widely used in biometric locks as they are considered steadfast forms of identification. The technology that is used for fingerprint scanners is very easy to install on a safe. Integrated locks may need a number of biometric identifications, like a thumbprint or a voiceprint that ensure additional security.
A list of authorized users along with some biometric traits is recorded at the time when biometric safes are installed. Such traits can be implemented by safes to identify the respective users. A few locks come with sophisticated technology that defines different users, who have the power to open them. A supervisor is a person, who may have the ability of reprogramming a safe. A temporary employee may be someone who will only reserve the right to open a safe.
A completely biometric safe requires a user to identify himself or herself. On successful identification, a safe opens by itself and a user can have access to whatever the safe contains. Combination safes may require a user to control its combination to make sure that a person has the authority to access the safe. A number of biometric safes also come with a panic feature that allows users to send out warnings on being compelled to open a safe.
Some high-end biometric safes are resistant to water and fire. Such safes can withstand harsh outcomes of events like earthquake, fire or a flood. Some safes are also designed to contain climate-sensitive valuables. Some other locks come with separate racks for storage devices.
