    The flagship feature of the iPhone 5s is the new Touch ID fingerprint sensor, and we're beginning to get a better idea of how it works.

    [​IMG]
    It appears Apple has designed Touch ID to be faster than entering a four-digit passcode, stating in its marketing materials that using Touch ID is "faster, easier, and even a little futuristic". It will allow users to store up to five fingerprints, allowing other trusted users access to a locked phone.
    Financial Times reporter Tim Bradshaw shared this video showing how the iPhone learns a fingerprint by scanning a finger a half-dozen times.

    TechCrunch wrote that once a fingerprint was successfully learned, "it worked flawlessly to unlock the device for every subsequent trial."

    Also, AllThingsD reports that third-party developers will not get access to the fingerprint authentication protocol, at least not initially.

    The iPhone 5s will cost $199, $299, and $399 for the 16 GB, 32 GB, and 64 GB models respectively with a 2-year contract. Non-contract, unlocked devices will be available at launch for $649/$749/$849.

    The iPhone 5s and the lower-cost iPhone 5c -- which does not have Touch ID -- will be available in stores in the US, Australia, Canada, China, France, Germany, Japan, Singapore, and the UK starting on September 20.

    Notably, there will be no preorders for the iPhone 5s.

    I for one love the sensor, I love the whole 5S, seems like people are haters on it. What did you expect? It's pretty darn cool!

    Agree 100% - looking forward to getting my hands on to see how compares to 4s and my other half's 5

    Has anyone heard if it will work just as well if someone uses their thumb? That would make it more convenient.

    I believe you can use any finger you'd like. I dunno if anyone has in practice yet or not

    I love the sensor! I hope that it can stand up to the wear and tear of everyday life. My iPhone 5 home button is always smeared with what ever food is on my littles one's hands.

    It seems to be designed for thumb. Go to you tube and look for iPhone 5s hands on. There's demo videos already

    This man speaks the truth. I have two kids and I have absolutely no idea what is on their hands but they play with my phone and there is a layer of goop on the phone even if I make them wash their hands BEFORE playing with it. Wizards I tell you. Dirt wizards.

    In the keynote it was mentioned that you could use multiple fingers. You could have the thumb and another finger (at least one other).

    If somebody chops off your finger, can they use it to unlock your iPhone? :eek:

    If someone chops off your finger, I think you have a bigger problem than your phone.

    Future breaking news story: Man knocked unconscious by thief. Thief steals man's iPhone only after using man's finger to unlock it. Man sues Apple.

    I beg to differ. Why wouldn't a thief take your finger along with your iPhone? If you think otherwise, you haven't done much traveling.

    Great invention for countries like Brazil. Now when you get robbed they won’t take just your iPhone. They will chop your finger and take it to.:eek:

    Yeah - and China, Africa, Latin America, Eastern Europe, Russia, South East Asia, US/EU cities -- just about everywhere actually -- except for maybe rural Europe and North America, and Japan.

    No the sensor detects pulse and temperature.

    I hope it detects pulse and temperature!! Otherwise this might actually stop me from buying it. The NSA probably already has my fingerprints from the numerous times I've gone through immigration at JFK, so that can't be much of a concern.

    The potential problem is that for a thief to access - and sell - the phone, they require your finger. So now they'll need more than just your phone!

    I doubt this would ever happen but in theory…

    Also, if Apple's touch ID works well, other companies will be implementing it in everything - computers, cars, doors… And then your finger will become a very desirable object for thieves.

    Oh Apple, why would you blunder so? Fingerprints are not passwords, let alone the perfect password. Touch ID -- identification -- yes, fantastic. Authentication? No. Everything you touch now has your "secret" password on it, and it bears mentioning that changing such a password is... difficult.

    Yeah - why are implementing something so potentially risky? You mention you doubt it will ever happen - that's naive - it can and will happen in many places around the world. A finger is nothing! They mug people for kidneys everywhere - even places like Manchester, UK - they wouldn't even think twice about taking someone's finger.

    Furthermore if they do implement it in cars, house doors, etc. - people are going to be getting their fingers stolen all over the place in all countries. This is crazy. I guess we'll just have to thank our lucky stars they're not implementing retina scanners.

    Dear god as someone has all ready said, it detects temperature and plus, a severed finger or a print of your print is no use. stop panicking.

    PS have you finished building your underground bomb shelter?

    I already know my wife's code and she knows mine. Don't give your spouse a reason to be jealous and this won't be a issue.
