Your fingerprint is the perfect password. You always have it with you. And no one can ever guess what it is. Our breakthrough Touch ID technology uses a unique fingerprint identity sensor to make unlocking your phone easy and secure. And with new developments in iOS 8 and Touch ID, your fingerprint will grant you faster access to so much more.
Place your finger on the Home button, and just like that your iPhone unlocks. Touch ID is capable of 360-degree readability, which means no matter what its orientation — portrait, landscape, or anything in between — your iPhone reads your fingerprint and knows who you are. And Touch ID even lets you enroll multiple fingerprints.
There’s a lot of technology at work below the surface of the Home button. Touch it and the surrounding stainless steel ring detects your finger and wakes the capacitive touch sensor. The laser-cut sapphire crystal surface of the button then directs the image of your finger to the sensor, which reads beneath the outer layers of your skin to get a detailed fingerprint. Software then reads the ridges of your fingerprint and finds the match to unlock your phone.
Touch ID does more than just let you unlock your iPhone. Your fingerprint can also approve purchases from iTunes, iBooks, and the App Store, so you don’t have to enter your password or billing information again and again. And for the first time, developers can integrate Touch ID into third‑party apps.
Apple Pay lets you use iPhone 6 to pay in hundreds of thousands of stores with a single touch. Just place your finger on the Touch ID sensor with your iPhone near the contactless reader, and your payment is sent. Apple Pay makes it just as convenient to pay within apps, too.
