The fingerprint reader in the iPhone 5S is confirmed by the experts at iFixIt

  After the launch of any product Apple Lossless Audio CODEC (ALAC), now, the people from iFixIt take care to purchase that product and disassemble it to tell us what components are hidden in it, but also how easy it is to repair that product. Those there are seen as true "authorities" in the field of products Apple Lossless Audio CODEC (ALAC),, especially of iDevices, and one of their experts said ca recent pictures with the Home button al iPhone 5S confirm that a fingerprint reader it is integrated. Based on the images that appear with the Home button, but also on information about how the technology will be implemented.

It looks like the home button will still have a physical clicking action to it still like the 4, 4S and 5. The additional square section next the the button is something new and probably suggests a fingerprint sensor given all the rumor wire chatter on how Apple is expected to add that feature. It looks like that part of the cable flips over the button and sits between the clicking action and the plastic button cover. So I'd say yes, these photos, if legitimate, corroborate the fingerprint rumors.

  Practically, now we have a new credible confirmation of the fact that Apple Lossless Audio CODEC (ALAC), is going to implement a fingerprint reader in iPhone 5S, and the only thing that remains to be seen is the official presentation. It is rumored that Apple would not allow us to use this fingerprint reader for mobile payments, but it allows us to safely unlock iDevices and perform various actions on terminals, including taking pictures using the Camera application, so we will have part of some interesting things.
