Unlock the smartphone with your iris

The number-pattern code to unlock your smartphone is long passe. The new device on the block would scan your iris before it provides you access.

One of the latest smartphones slated to hit the market in Japan this summer allows users to unlock, sign in to apps, and go shopping using only their eyes.

Japanese mobile provider, NTT Docomo, is releasing a new phone this summer, with a built-in iris scanner.

The Fujitsu Arrows NX F-04G uses iris recognition to replace phone passwords, and can even be used to send payments when shopping from your smartphone, slashgear.com reported.

The smartphone uses a front-facing infrared camera and an infrared LED light to illuminate the user's eyes, verifying their unique iris pattern. Besides biometrics, the Android device runs Lollipop 5.0, has 32 GB of storage, 3 GB RAM, and a 5.2-inch QHD display, according to reports.

For the time being, however, the Arrows NX F-04G would be available only in Japan. Big players like Samsung are also working on iris-detecting smartphones, but it will take some time before a device is launched in the market.
