On the eve of the 2013 iPhone event, here’s some final thoughts from Rene Ritchie last week on what we’re going to see in the iPhone 5C:
Apple will likely have to constrain fingerprint authentication to device unlock at first to prove the concept. People are change adverse and we generally fear new technology. It’s why car makers dribble out things like automatic parallel parking instead of just unleashing Knight Riders onto the street all at once.
The iPhone 5S will have a fingerprint scanner in the Home button. You’ll touch it. It’ll authenticate and authorize you to access your device. Over time, and over the course of software and hardware updates, as the technology and acceptance of it improves, it’ll get tied into iCloud so it can unlock all your keychains (passwords), iTunes so it can unlock all your digital transactions, and Passbook so it can unlock all your real world transactions. It’ll become your Apple ID. It’ll become your wallet.
And like Passbook, and Siri, it’ll be an introduction, a first step, a work in progress. In typical Apple fashion, when they attempt to mainstream a previously niche technology in order to enable a feature they want to provide, they’ll start slow, but it will have a lot of really obvious potential.
