We quickly extract the home button and Touch ID, Apple's new fingerprint scanner. Time to dust for prints!
A CMOS chip, the Touch ID is essentially a bunch of very small capacitors that creates an "image" of the ridges on your finger.
The sensor technology, developed by AuthenTec and bought by Apple a year ago, reportedly stores your fingerprints locally, so giving your iPhone the finger will not make it all the way back to Cupertino.
We worry about how well the sapphire crystal covering the sensor can protect it from degrading over time like most CMOS fingerprint sensors. If not, it could become a ticking time bomb, just like that super-glued battery.
