With iPhone 5s, getting into your phone is faster and easier with Touch ID - a new fingerprint identity sensor.
Touch ID is a seamless way to use your fingerprint as a passcode. With just a touch of the Home button of the iPhone 5s, the Touch ID sensor quickly reads your fingerprint and automatically unlocks your phone.
You can even use it to authorise purchases from the iTunes Store, App Store, and iBooks Store. Touch ID is capable of 360-degree readability, which means no matter what its orientation, your iPhone reads your fingerprint and knows who you are.
