What does the new iPhone 5s do?

Today I went to the AT&T store and saw alot of people there
And I just wanna know what's difference between the new iPhone 5s and Old iPhones?

Basically it scans your fingerprint so only YOU can unlock your phone. That's pretty much it.

The 5S hardware is twice as fast and is 64bit (and it is the only 64bit smartphone on the market today).It also has the aluminum casing and fingerprint access which is what I like. I also like that you don't even press the home button (won't wear it out) as the fingerprint is automatically recognized when you just put it over it. Airdrop and also the best camera of any phone out there today including slo mo video and burst mode photo taking… Pretty slick.
