Exchanging a regular lock for a keyless door lock doesn’t require many hassles. From there, operating the system is even easier. No resident needs to remember keys because multiple fingerprints can be stored on a finger lock. Fingerprints that don’t match the stored prints are denied and refused entry. Without a doubt, this type of system is many times more secure than an old lock and key combination. Temporary authorizations stand out as a useful benefit of biometric locks. A given person can be given fingerprint authorization on a temporary basis. Also, many systems include integration with smartphone apps via Bluetooth or WiFi. If a fingerprint doesn’t work, then the app can authorize entry instead as a fallback option. The best biometric locks are quite accurate and come with extra features like an emergency keypad and more.
