What Else Can Apple Do With Its Fingerprint Scanner?

Right now, the fingerprint scanner has one key feature: it allows users to unlock their phones without entering a passcode. Apple could take this one step further and allow multiple users -- on multiple devices -- to be identified in this regard.

Then, when another user touches the home button, the device would swap those apps/feature out for the current user's preferences. It's a minor tweak, but it's the kind of seamless feature that Apple is known for producing.

to scan more than fingers. Even cats can unlock the iPhone! But it is unclear if the iPhone 5S can actually determine which body part is being scanned. If it can, there are dozens of cool/gimmicky apps that could be developed.

There has been a lot of speculation that Apple will

the mobile healthcare industry with new features added to its devices. As the firm's biometric technology evolves, these elements could theoretically make their way to the iPhone's home button. Disclosure:
