Apple Announces Touch ID Fingerprint Scanning
Apart from the new A7 chip
that will be included in the iPhone 5S
, Apple also announced a new fingerprint-scanning technology called Touch ID on Tuesday.
In the same place as the iPhone 5S’s home button, is a new fingerprint scanner. The scanner can read the user’s fingerprint rather than having to use a passcode to unlock the device. Apple notes that more than half of iPhone users don't use a passcode because of the cumbersome steps required to set one up. The fingerprint scanner can also be used for signing into iTunes.
The fingerprint scanner is 170 microns thin, has a 500ppi resolution, offers a 360º reading capability, and can scan the sub-epidermal skin layers.
Apple shows is the layers of the fingerprint scanner, which includes a sapphire crystal layer, stainless steel detection ring, sensor, and tactile switch:
For those of you worried about your personal security, Apple assures us that our fingerprint information is never uploaded to a remote server.
This seems like a really cool way to unlock your iPhone, what do you think?
