Leaked iPhone 5S home button images further suggest a fingerprint scanner

Rumors of a fingerprint sensor in the next iPhone(s aapl) are nothing new. In fact, Apple has been expected to implement a fingerprint sensor in the iPhone since it acquired AuthenTec last year. Now, less than a week ahead of the phone’s unveiling, alleged images of the iPhone 5S home button have surfaced, showing a redesign from the iPhone 5 which suggests that Apple is indeed planning to incorporate a fingerprint sensor this time around.

These high-res images are once again courtesy of Sonny Dickson, who has brought us the majority of Apple leaks this summer, from the iPhone 5C to the iPad mini. Now, I’m not even sure what a fingerprint sensor looks like, or if we can even see one in these images without a more detailed closeup. What I do know, however, is that the sensors and wiring used here are visibly different from the iPhone 5. Considering Apple isn’t expected to make many other physical changes to the phone, it gives credence to the idea that a redesign could have happened to make way for a fingerprint sensor.

Why would Apple want to add a fingerprint sensor to the iPhone 5S anyway? Well, by placing a fingerprint sensor under the home button, it adds an additional layer of security, for one thing. It would also let Apple do away with the “swipe to unlock” feature. The home button itself is expected to be made of the same scratch-resistant sapphire crystal found on the lens of the iPhone 5.

Apple has confirmed that it is holding an event on September 10 where the iPhone 5S will almost certainly make its debut. So it won’t be long before we see whether or not a fingerprint sensor is included, and exactly what Apple plans to do with it.
