Apple announces iPhone 5S with fingerprint sensor

At its media event today, Apple introduced the new iPhone 5s. In line with expectations, the iPhone 5s will be the same size and design and the current iPhone 5 but will feature improved specifications and will be available in three colors: silver, gold, and space gray.
Internally, the iPhone 5s will feature a 64-bit A7 processor that will be up to twice as fast at CPU tasks. Another significant new feature is a “Touch ID” capacitive fingerprint sensor built into the home button that’s capable of scanning sub-epidermal skin layers. Touch ID can be used to unlock an iPhone and authorize iTunes purchases.
