iOS 7.1.1 brings zippier, more accurate Touch ID
Originally, Touch ID was supposed to improve its accuracy every time you scanned a particular finger. But that was not true if your initial set-up was a bad one. If the first scan you took had problems, your scans would not gradually improve, unless you set-up your finger again from scratch.
With iOS 7.1.1, a poor set-up the first time you scan your finger, won’t lead to constantly poor readings. In addition, the update improves accuracy using Touch ID. The update to iOS 7.1.1. also lowers the number of calculations required by the Apple iPhone 5s, before it unlocks the phone. Bottom line? A faster and more accurate fingerprint scanner on the device.
And code found in iOS 7.1.1, reveals that Touch ID is coming to the Apple iPad Air 2 and/or the next iteration of the Apple iPad mini with Retina display. The faster and more accurate the fingerprint reader works, the less “gimmicky” and more use useful the feature appears to be.
