Harfo Fingerprint Lock
Score: 72/100
Wyze Bolt v2
Score: 88/100Rankings

The Wyze Lock Bolt v2 is a Wi-Fi-enabled smart deadbolt featuring BHMA Grade 2 security and an AI self-learning fingerprint scanner. It offers built-in remote access without a hub and local data storage for privacy, though it requires 8 AA batteries. It is best suited for budget-conscious users seeking keyless entry on standard US exterior doors in covered areas.

The Harfo Fingerprint Door Lock offers robust keyless entry with high-accuracy fingerprint scanning and multiple access methods. Its main limitation is the poor visibility of the touchscreen keypad in daylight and the need for a separate gateway for smart features. It is best suited for users prioritizing keyless convenience and durability over advanced smart home integration.
