You realize that company is a faction of the engineering that went into their methodology right? You think Apple just bought that company and threw the tech in? Laughable.That's true but Apple had nothing to do with the development of Touch ID.
They just bought AuthenTec, it's their invention, they developed it (and continue to inside Apple).
When it comes to face detection:
Apple acquired RealFace a few months ago, I hope RealFace developed face detection better than what we have seen so far from others. It's definitely way slower than touch id in their demos.
Here's a User Demo of the face detection company Apple bought.
