Fingerprint scanner for iPhone 5S
A "BIOMETRICS kit" folder has been discovered in the latest beta version of iOS7 - Apple's iPhone and iPad operating system - which was pushed out to developers on Monday.
Its presence all but confirms reports that the iPhone 5S, expected to be unveiled in September, will have a fingerprint scanner embedded in its homekey.
Rumours that Apple intended to add a new layer of security to its devices started last year when it bought AuthenTec, which builds banking-standard biometric scanners.
Biometrics offers better protection than text-based passwords.
