There’s a new smart lock in the works that does away with all these cumbersome key- and phone-based unlocking schemes. Instead, the Ola lock uses a fingerprint sensor. Ola is the first smart lock on the market to incorporate Bluetooth 4.0 connectivity and capacitive fingerprint technology, making Ola not only keyless but phoneless. If you’re concerned that someone might swipe your prints, Ola’s inventors claim that fake fingerprints won’t work on their lock. Ola runs on four AA batteries.
