You check your iPhone dozens & dozens of times a day, probably more. Entering a passcode each time just slows you down. But you do it because making sure no one else has access to your iPhone is important. With iPhone 5s, getting into your phone is faster, easier, & even a little futuristic. Touch ID is a fingerprint identity sensor. Put your finger on the Home button, & just like that your iPhone unlocks. It's a convenient & highly secure way to access your phone. Your fingerprint can also approve purchases from i Tunes Store, the App Store, & the i Books Store, so you don't have to enter your password. & 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 & knows who you are. & because Touch ID lets you enroll multiple fingerprints, it knows the people you trust, too. There's fast. & then there's A7 fast. The A7 chip gives you CPU & 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 superslim phone. & because i OS 7 was built specifically for 64-bit, it's uniquely designed to take advantage of the A7 chip. A7 supports Open GL ES version 3.0 to deliver the kind of detailed graphics & complex visual effects once possible only on Mac computers, PCs, & gaming consoles. The difference is amazing. Take the imaginary worlds in games, for instance. Textures & shadows look more true to life. Sunlight reflects off the water. The whole experience feels much more realistic. i OS 7 & all the built-in apps are optimized for the A7 chip. The Camera app is a great example. It takes advantage of a new image signal processor built into A7 to give you up to 2x faster autofocus, faster photo capture, & higher video frame rates. The M7 coprocessor is like a sidekick to the A7 chip. It's designed specifically
