Biometric security on our personal devices is almost always a good thing. When it works, it’s a fast, convenient, and (largely) secure way of getting into our gadgets. And while fingerprint sensors are slowly falling to the wayside in favor of face-scanning IR arrays (like Windows Hello cameras or the iPhone’s Face ID), I’m still particularly fond of fingerprint readers — specifically, fingerprint reader buttons on laptops, which combine the idea of booting up and logging on into a seamless process.
