Continental Automotive showcased its new Face Authentication Display, which uses biometric recognition to identify the owner and anyone authorized to use whatever car. There are cameras mounted in the B-pillar and instrument cluster. You walk up, and the car recognizes you, unlocks, and activates. And before you ask, the answer is no. You can’t access the vehicle using a photograph or mask.

The humble car key was good enough for a hundred years, but Mercedes-Benz changed the game when it introduced the W220 S-Class Sedan in 1999. It was the first car equipped with a key that sent out a unique frequency, which unlocked the vehicle as the driver. Nowadays, it’s a common piece of tech, and automakers constantly try to outdo each other with new smartphone-based key technology.

Facial recognition is already widely used in the smartphone industry, and it’s only a matter of time before it filters down into cars. This tech could also help detect inebriation, preventing you from driving drunk.
