Meet the Ultraloq UL3 Lock: a Bluetooth enabled smart lock that lets you open it using a fingerprint, smartphone, knock, code, or key. Your smartphone not only serves as your key but lets you see users and log who has entered your home. The fingerprint reader uses a scratchproof, dustproof and waterproof sensor that can recognize up to 95 fingerprints.
Don’t want to grab your phone to open your door? Just knock on it 4 times. The battery lasts up to a year, which is a plus.
