The new iPhone 5s comes armed with a high-profile fingerprint scanner inside the Home Button. Called Touch ID, the new system aims to replace your passcodes and App Store password with a fingerprint scan. As you touch the Home Button the Touch ID sensor reads your fingerprint and unlocks your iPhone. No more sliding to unlock, and no more entering four digit passcodes. Touch ID aims to make the iPhone more secure and easier to use at the same time. See: iPhone 5s review & Apple sells more than 9m iPhone 5s, 5c during launch weekend
