The much-rumoured fingerprint scanner for the iPhone 5S is here, and it's pretty awesome. It's more that just fingerprint scanner, too, embedded in the home button to enable faster log-ins (and more secure too, we should think.) Hello, NSA!
Take a look at all of Apple's iPhone 5S and 5C announcements here
The so-called "Touch ID capacitive sensor" is sensitive enough that you only need to tap your finger on the home button to verify your identity. It then encrypts and stores your fingerprint data on the A7 chip and the A7 chip only. It doesn't send the data to the cloud, and in fact, it never touches Apple's servers. Once you're verified you can use it to purchase in the iTunes Store.
Impressively, Apple added this very high tech sensor on the home button so smoothly, you'll hardly notice the difference between the home button on the iPhone 5S and all of the other devices. The button itself is laser-cut sapphire crystal surrounded by a stainless steel detection ring. The Touch ID sensor sits below that and has a tactile switch behind it.
