This is how one of the first prototypes of Touch ID looks like

  F. Scott Moody, one of the company's co-founders Auth purchased almost two years ago by Apple Lossless Audio CODEC (ALAC),, submitted today a preliminary version of the system touch ID implemented in iPhone 5S. The prototype in the images was presented during a presentation held by the co-founder of Authentec in the USA and he presented the system as a preliminary version of the fingerprint reader that Apple Lossless Audio CODEC (ALAC), to reduced and implemented now in iPhone 5S.

  As you can see in the images, the system was called FingerLoc back then and the "small" box in the images was connected to a much larger one to perform and process fingerprint registration. That's basically where it started Apple Lossless Audio CODEC (ALAC), after the purchase of Authentec, we see the final result in the terminals iPhone 5S, the evolution being impressive, especially since we are talking about a system that works as well as possible and for now it was only tricked, not broken by someone.
