NEW iPHONE 5S

How iPhone 5S makes your finger into a password The most impressive feature of the new iPhone 5S may be its ability to turn your finger into a password. Touch ID is Apple's name for a new fingerprint scanner that would act as a security tool for log-ins and for making purchases from iTunes and other Apple stores. "Your fingerprint is one of the best passwords in the world," said Dan Riccio, a senior vice president for hardware design at Apple, in a promotional video. "It's always with you and no two are exactly alike." Apple unveiled the iPhone 5S, along with a cheaper, simpler iPhone 5C, at an event Tuesday at the company's California headquarters.

According to Apple a fingerprint -- up to five prints from different users, depending on who else shares your phone -- can be read by the sensor from any angle to give access the same way a password does currently. The fingerprint data is encrypted, Riccio said, and stored internally on the phone. "It's never available to other software and it's never stored on Apple's servers or backed up to iCloud," he said. The iPhone isn't the first phone to have a fingerprint sensor. In 2011, the Motorola ATRIX 4G included one, though adoption among users wasn't particularly high and the company eventually discontinued the feature. And at least one Android phone to be released this year also will have the technology, according to a Wall Street Journal report. Some laptops and PCs have had fingerprint readers for several years now. But the technology has never really caught on, with users often complaining about them being balky and unreliable.
