Polar ID Is the Face ID Rival for Android Phones, and Could Even Beat Apple

A little more than six years ago, Apple unveiled Face ID. It was a new method to biometrically unlock iPhones and authenticate purchases by scanning your face. Google's Pixel 8 has face unlock, but it has trouble working in the dark; the face unlock available on Samsung smartphones can't be used for secure applications, such as banking. In Android land, the fingerprint scanner is king, but that might not be the case for long. Metalenz, a startup pioneering optics technology called "optical metasurfaces," is hard at work on introducing secure face authentication to Android with its Polar ID technology.
