iOS 7 beta 4 contains key evidence that iPhone 5S will have fingerprint sensor

Text strings in new iOS 7 beta describe fingerprint recognition system built into Home button

The new iOS 7 beta rolled out by Apple on Monday contains significant evidence to support the speculation that the next-generation iPhone, expected to be named the iPhone 5S, will have a fingerprint sensor built-in to the Home button.

A folder called "BiometricKitUI.axb" was spotted in the fourth beta of iOS 7 beta by Hazma Sood, along with an accompanying text string describing an image of "a person holding an iPhone with their right hand while touching the Home button with their thumb." A second image has the same description, but the person holding the iPhone in the opposite hand.

In addition, also described in the text is an image of "a fingerprint that changes colour during the setup process." This will be accompanied by a status indicator that will tell the user when the recognition process is complete.

A fingerprint sensor could be used to help improve the security of the iPhone to allow safer mobile payments. It could also be used in conjunction with Apple's Passbook app.

This is not the first we've heard about the possibility of a fingerprint sensor in the next iPhone. Last year, Apple bought AuthenTec, a company that specialises in security systems such as fingerprint scanners, which sparked speculation about the introduction of such technology in future iOS devices.

An Apple job listing in April also hinted that the company is working on fingerprint sensors for an upcoming device.

Numerous reports have suggested that the introduction of a fingerprint sensor could contribute to delays expected to plague the iPhone 5S. Trusted analyst Ming-Chi Kuo of KGI Securities has said that the technology, which is expected to be built underneath the Home button, poses multiple technical challenges for Apple.

A smarter way to print for busy small business owners, combining speedy printing with scanning and copying, making it easier to produce high quality documents and images at a touch of a button.

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.
