SAN FRANCISCO ? Apple’s new feature that lets users unlock phone by scanning their fingerprint may be one-upped by Samsung in next year?s Galaxy S5 that will offer an iris-scan unlocking feature, contends reports out of Korea.

CNET?s sister site ZDNet Korea quotes industry sources who say the company’s next flagship mobile will pack an iris scanner – a first for any phone – and a massively high-resolution display. These are just rumors for now, but it sounds like we could find out more soon.

According to the sources, the unnamed phone – most likely the Galaxy S5 – will debut at Mobile World Congress in Barcelona in late February. The iris scanner is likely to work like the iPhone 5S’s handy fingerprint scanner, meaning you can use your own unique biometrics to unlock the screen. A reliable, secure eye scanner would be harder to fool than a fingerprint detector, but would need a very high resolution camera.
