A: There are some downsides to buying a safe with a biometric lock. The cost can be a factor as safes with biometric locks typically cost more than a safe with a mechanical or digital lock. As biometric technology grows, the cost will come down. If you are price conscious, a safe with a mechanical lock or digital lock may be more economical.
If you work with your hands a lot such as workers or musicians, you end up developing ridges, calluses, and parts of your fingerprints may even wear off. Or if your hands regularly get cuts or abrasions on your fingers that may cause your fingerprint to change. These may all cause issues with reading your fingerprint, especially if you buy a safe that has a low-quality reader. You can always scan multiple fingers to try and get around that. We suggest only buying a safe with a fingerprint reader that has a low false read rate. Or look for a safe with a mechanical or digital lock so that you do not need to worry about your safe not opening when you need it the most.
Other things on your finger such as moisture, dirt, oils, blood, lotions, sunscreen, glue, and other kinds of materials can also cause problems reading your fingerprint.
If you are over 55, this can affect how the lock reads your fingerprint as well. This is due to thinning fingerprints. Almost all fingerprint readers will lose accuracy with increasing age.
