According to Hall, Apple’s inclusion of a laser-based 3D sensor, which may be designed in a “stacked” optical column, will be far more accurate compared to Touch ID, a system that’s rumored to be on the chopping block. Apple is reportedly using technology from Primesense, a company it acquired in 2013.

This isn’t the first time we’ve heard the iPhone 8 may include a laser sensor for facial recognition. In January, another analyst claimed the upcoming device would sport a laser sensor and infrared sensor mounted near the front-facing camera.

As advanced as the new feature sounds, it may not be exclusive to the iPhone 8. Hall hints there is “more unit volume” for production of the new system, suggesting we may see the technology appear in the iPhone 7s and iPhone 7 Plus. That sounds unlikely, but certainly not out of the realm of possibility.

Facial recognition is by no means new

Apple has been sitting on Primesense technology for several years now, so it’s about time we see why the Cupertino company made the acquisition. Introducing facial recognition technology to the iPhone 8 seems like the perfect fit. But, remember, facial recognition is nothing new in mobile.

Other potential changes coming to the iPhone 8 may include a 5.8-inch OLED display, a fingerprint reader embedded into the screen, and a revamped design.
