Biometric safes have a number of advantages over safes with other available locking mechanisms, such as key-locks, dial combination locks, and electronic locks with digital keypads. One advantage is that you donít have to worry about being locked out of your safe if you lose the key to the safe or if you have forget or misplace the combination to the safe. With biometric locks, your finger is your key, which you always have with you. Another advantage of safes with biometric fingerprint locks is that they can be programmed to accept several fingerprint scans from several authorized users, such as all the members in your household or some subset, such as only the adults in the household. You can even program a biometric fingerprint lock to accept several of your own fingers.
The one disadvantage of safes with biometric fingerprint locks is their price. Compared to traditional locking mechanisms, biometric fingerprint locks are more expensive. Over time, as manufacturing processes are refined and economies of scale are reached, the price will decline and safes with biometric fingerprint locks will become more commonplace. For now, safes of this type, while highly desired, remain out of reach of many consumers for their relatively high cost.
Biometric safes often have one or more backup entry options, such as a mechanical key override or a secondary digital keypad. Although modern fingerprint readers are quite reliable, backup key locks and secondary digital keypads are still potentially very useful because they provide a means of access in case something goes wrong, such battery failure or water damage.
