[VIDEO] Test run of an in-glass fingerprint sensor

Marques Brownlee shows off an in-glass fingerprint sensor and compares its performance side-by-side with an iPhone 8 and Touch ID.

There’s a lot to love about this video but, for me, the highlight is Marques explaining just how the OLED reflection process works, how it shines the screen at your finger and uses the bounced light to detect your fingerprint.

Beautifully done.
