While most locks use physical keys to open them, some are now able to unlock with the touch of a finger. These devices, designed for bikes, lockers and more, use a technology called biometrics, which harnesses each person’s unique identifier, from scanning their iris to their fingerprint.
There are seven on our list – two that we tested ourselves – that can work to secure a door, bike, scooter, and your locker at school or gym. All but one cost less than $ 100, and some are from names with a rich history to protect what you value.

Benjilock Sport Fingerprint Padlock
Benjilock is a company known for its biometrics, and it’s backed by Hampton known for their locks – so marriage is a good marriage. The Benjilock fingerprint sport lock looks like another gym lock, but at the bottom is a USB port for charging the device and the front has a sensor where you place your finger to open it.
You can store up to 10 fingerprints here, and the battery, on a single charge, should last up to six months. We reviewed the lock in white, but the website currently has the lock available for $ 29.99 and just in red and black.

Tapplock lite likes to talk about its lock’s weight and operating speed, unlocking in just 0.8 seconds. We’re a little more interested in the fact that the company claims it can store 100 different fingerprints inside. Everything is controlled through the Tapplock app (iOS and Android), which connects to the lock itself via Bluetooth, a second way to unlock the device. And you can actually use a third method to unlock the lock – Morse code.
The battery inside works for eight months, and you can pick one on the website for $ 49 in red, black, or yellow – or a missing double pack for $ 91.
