The HQ Series of Biometric Keypad Safes from Barska offers two ways to access the contents inside. First, the Biometric module allows the user to store up to 30 unique fingerprints, allowing those who have programmed their unique fingerprint into the safe to be able to quickly access the safe in seconds. In the event that someone needs to access the contents of the safe when a registered user is not around, a PIN Code can be used to access the safe. For those looking for a quieter way to access the safe, the HQ Series offers a programmable sound option to eliminate any of the default alerts that occur when opening the safe. In the event that the batteries run out, 2 back-up keys are provided so that the safe can still be accessed.
