Carrier iPhone 5S Rumors; what could a Fingerprint Scanner do

[AppleShinobi000]

Ok so up until now the iPhone S line always seems to bring a killer feature, the 3GS brought Video Recording, the 4S brought Siri and the 5S is highly rumored to bring a Fingerprint Scanner.
So besides from security upgrades, what could a Fingerprint scanner actually bring to the table that could be that useful?

Depends on the Apple API and what they're willing to let it do and not do. I remember a few years ago it was big on windows laptops. Used to sign into websites stuff like that but got old fast.

Log into a bank account or email account...Paypal said they would like to see Apple make this happen.

It would probably be a little "gimmick" that would die fast.... I mean look at Siri, I don't know a single person who actually uses Siri daily. I mean sure sometimes its cool, but no one uses it as Apple hoped people would.
Also, from what I've heard at least, it may take a while to scan your fingerprint.

SIRI is a work in progress, and will be for quite a while. Just like Dragon Natural Speaking software that was not and still not 100% perfect.

FingerPrint scanner will be a blessing for those that log on numerous times a day, but hope Apple will have done some homework to make it work over the desktop versions. No one knows yet. Stay tuned.
