Apple's new iPhone may have fingerprint sensor
Apple's next iPhone may come with a new feature: a fingerprint sensor.
On Monday, the iPhone and iPad maker released a new beta version of its software, iOS 7, to developers. According to 9to5Mac, there is a folder in the beta version of the software called a "Biometric Kit" with a string of code that says "A fingerprint that changes colour during the setup process."
The "Biometric Kit" folder has led many to speculate that the new smartphone, dubbed the iPhone 5S, will have a fingerprint sensor that is used as part of the home button.
Such a feature could be used to replace Apple's current lock-screen system, which requires a four-digit PIN number.
Of course this isn't the first time that it has been rumored Apple would build a fingerprint sensor into its hardware. Last July, the tech giant acquired AuthenTec, a company that makes biometric security hardware, for more than $350 million.
Analysts expect the Cupertino, Calif., company to reveal the next generation iPhone this September or October, however, the company has not confirmed an exact date.
Besides a fingerprint sensor, the new phone is also rumored to feature an enhanced camera, an A7 processor and an improved Siri system.
