Samsung Galaxy S5 rumoured to include eye-scanning technology

Samsung could be looking to one-up rival Apple with the introduction of an eye-scanning sensor in its next-generation Galaxy S5 smartphone, which is expected arrive next year.

Smartphones and other devices with fingerprint scanners have existed before, but the Touch ID technology chosen by Apple for its latest iPhone 5S handset is a little different. Instead of swiping your finger over a strip-like sensor, which can lead to inaccurate readings, Touch ID works by simply pressing your finger against the home button to unlock the phone.

It's a neat trick, although its contribution to security was brought into question when a group of German researchers were able to create a fake fingerprint and unlock the device using little more than a camera, printer and PVA glue.
