Apple is working on a software update of the Touch ID feature - good because I have problems with it
While initial reviews of Touch ID generally praised the “single touch” system for being easy to set up and consistently accurate, a number of users have reported what is being called “AuthenTec Fade,” or intermittent recognition failures that begin to occur months after first configuring one's prints.
The TouchID on my iPhone 5S is one of the few things I don't like with it. No matter what I do, it almost always has problems recognizing my fingerprints. In fact, because of that problem, typing the four digit pin code is faster for me than trying to use the TouchID feature… So let's hope this new update fixes most of the problems I have.
