The Barska AX12840 HQ200 Biometric Digital Keypad Safe is the perfect solution for storing your valuables securely and conveniently. The HQ200 Safe has a new module that offers both a Biometric Fingerprint Scanner and a Numeric Digital Keypad. The HQ200's BioSecure Technology only recognizes the fingerprints that have been registered in the safe, and the PIN Code that you create acts as a backup in case someone else needs to access the safe. You can also use the backup keys or a 9V Battery as an external power source when the battery is low.
