What kind of things could a fingerprint scanner be used for on a phone?

    Besides unlocking a device, what kind of use would a fingerprint scanner serve? It doesn't seem like a necessary feature in a phone as there is a password lock, so it wouldn't be considered as being "major" feature update...

    If the right APIs are added, other apps that have a passcode lock could be used to work with a fingerprint. Right off the top of my head, I can think of half a dozen apps I have where I need to login. That would be nice to just open an app without the need for a passcode / password while still keeping them secure from prying eyes.

    I would welcome it as a security feature. Like require a fingerprint scan to reset the device, which may hopefully deter people from stealing phones...etc.

    I think this will be the biggest reason for parents to set a finger scan "passlock" for when they hand off their phone to their kids to play games which leech off your wallet. Now when an in-app purchase is needed, the kid can't just blindly buy buy buy because it will require the parent's fingerprint scan, not just a stolen passcode.

    I think the biggest feature will be the ability for third parties to have access to it. This would allow Apple to basically act as a two-factor login system using fingerprints for 3rd parties.

    I'll want to see it used as authentication in third party apps. I'd love to use it to unlock my 1Password app instead of typing in a long password on a phone.

    Also, what about using it as a component of two-factor authentication with online services?

    Maybe for young kids. Mine would probably learn how to duplicate my print. And that's still no different than a passcode you type.

    Duplicate your print? I'm pretty sure they are not using a fingerprint scanner designed in the 1970s.

    Not sure how sophisticated this scanner would be but you can beat/trick most basic ones very easy.
    Kinda sounds like a useless gimmick feature to me but will wait to see how they will implement it if they do release it on the next iphone.

    You'd be surprised how easy they are to dupe;)

    I can say that some of the tech that apple bought is quite sophisticated. They can tell if it is a living finger, so that basically throws out the window replicating a fingerprint or even severing a guys finger to unlock it. The question is whether they will use it.

    I honestly don't expect this tech to come to the iPhone any time soon, if at all. I would suspect we see this in their macs first. Just a feeling, no empirical evidence on that.

    I hear you.
    Hope its not like those cheap PC laptops with the finger scanner where you can trick it with a paper fingerprint photocopy:D

    Unlocking the phone, access to certain apps, financial transactions.

    Using fingerprint security for financial transactions would be amazing. I still have no idea why we sign slips of paper or little electronic boxes when using cards. You can buy everything on the entire Amazon site and never sign your name.

    If Visa had an app that required an approved fingerprint to complete a transaction on a credit card, this is much more secure than any code or signature. The system would obviously need security parameters, but it's much easier to hack into an account by guessing passwords compared to faking or overriding fingerprint recognition.

    We used a handprint scanner in college in the late 1990s for access to our dorms, access to the dining halls and numerous other things. Maybe this is that finally hitting the rest of society.

    This is the most appealing thing about the scanner.....not having to log into apps. I can't tell you how annoying it is to have to log into HBO Go whenever the app decides to kick me out. I know it only takes a few seconds, but not having to type in a password would be really nice.

    Interesting, I hadn't thought of that.

    lolz, this. It's bloody easy to get by a fingerprint scanner if you have access to something the person has touched without a gloved hand.

    Like many things it's the idea of the feature that's exciting more than practical application.

    Only in the movies.

    Apple's scan tech reads subcutaneously. It is impervious to surface skin abrasions and fingerprint fading due to age. It also knows if the finger is dead or alive.
