officially announced and unveiled the iPhone 5S, which is supposed to be twice as fast as its predecessor and comes with a fingerprint sensor.
The fingerprint system, dubbed Touch ID, will let you unlock your phone by simply placing your finger on the home button.
We’ve broken down how the system works.
With Touch ID, all you have to do is touch your finger to the home button to unlock your phone. No more need for passwords .
With the new iPhone, you'll be able to use your fingerprint to buy apps, music, books, TV shows, and movies through the iTunes Store.
But first you'll need to add your fingerprint and set your phone to allow its use instead of your Apple ID password.
Simply tap your finger to set it up. The more you use TouchID, the better it gets at detecting your finger.
TouchID then maps the details in the ridges of your finger. These ridges are smaller than the eye can see.
Your fingerprint gets encrypted and stored within the A7 chip. It's only accessible by TouchID, and will never be stored on Apple's servers or backed up on iCloud.
