Apple’s just introducing TouchID, which uses your fingerprint to unlock and get access to your iPhone. It’s called the Touch ID sensor. It’s capacitive, 170 microns thin. 500ppi resolution, which is quite impressive. It can scan in 360 degrees, so you don’t have to have the orientation right, and it can learn multiple fingers. The TouchID reads fingerprint at very detailed level also it scans sub-epidermal skin layers. It’s in the home button, with sapphire crystal top, a “stainless steel detection ring” and a tactile switch under the fingerprint sensor. You just touch the Home button and it unlocks the phone. “It’s a joy to do,” says Phil. Certainly an improvement over passcodes and no more swipe.

Additionally, you don’t need to enter your password when buying things anymore! Just use your thumbprint. this is definitely a great thing :). The fingerprint info is stored inside the A7, deep in some chip sub-section. Not stored anywhere on Apple’s servers. so you don’t need to worry about it.

“Making something as important as security so effortless, so simple. We believe that technology is at its very best, and its most empowering, when it simply disappears” – Apple
