WSJ tips iPhone 5S fingerprint sensor

Apple(s aapl) is holding its big event in just a few short hours, but that hasn’t stopped the rumor mill from churning. A last-minute report from the Wall Street Journal all but confirms a fingerprint sensor for the iPhone 5S.

According to sources, a fingerprint scanner will be built into the “more expensive of two iPhones.” If you’ve been following along, that’d be the iPhone 5S, which is expected to be the successor to last year’s iPhone 5. Apple is also likely to introduce a second new iPhone for the first time ever. This phone, the iPhone 5C, is believed to be a lower-cost option with similar hardware to the iPhone 5 and a colorful plastic casing.

A fingerprint sensor in the iPhone has been expected since Apple acquired AuthenTec last year. Just last week new images turned up that further suggest a fingerprint sensor will be embedded underneath the home button. This would allow Apple to do away with the “swipe to unlock” feature, as the screen can automatically unlock upon sensing your fingerprint. The home button itself is believed to be recessed, and made of the same scratch-resistant sapphire crystal found on the lens of the iPhone 5.

We’ll know for sure at 10AM PT today when Apple’s event kicks off. Om Malik will be in the audience live-blogging. To get the news as it happens, you can follow along here.
