With iPhone 5s, getting into your phone is faster, easier, and even a little futuristic. Touch ID is a fingerprint identity sensor. Put your finger on the Home button, and just like that your iPhone unlocks. It’s a convenient and highly secure way to access your phone. Your fingerprint can also approve purchases from i – Tunes Store, the App Store, and the i – Books Store, so you don’t have to enter your password. And 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 because Touch ID lets you enroll multiple fingerprints, it knows the people you trust, too. There’s fast. And then there’s A7 fast. The A7 chip gives you CPU and graphics performance up to 2x faster than the A6 chip. Even more impressive, A7 makes iPhone 5s the first 64-bit smartphone in the world – that’s desktop-class architecture in a super slim phone. And because i – OS 7 was built specifically for 64-bit, it’s uniquely designed to take advantage of the A7 chip.
