ZTE's Grand S3 smartphone uses retina-scanning biometric technology

ZTE’s new flagship smartphone is taking a different approach to biometric authentication through the use of retina scanning technology from EyeVerify.
The ZTE Grand S3 is the first smartphone to use eye-based biometrics for security purposes which ZTE is calling Eyeprint ID. With the phone in front of your face, the screen will turn white briefly to help illuminate your eyes. The retina scanner then goes to work and using the front-facing camera, scans the unique pattern of veins in the eye for authentication.
The whole process is said to take as few as 800 milliseconds although in real-world testing, PCWorld said to expect about a full second.
As of now, Eyeprint ID is only used to unlock the phone although ZTE has plans to extend its functionality to apps. They will also bring it to other handsets in the future.
The Grand S3 features a 5.5-inch display operating at 1,920 x 1,080 and is powered by a quad-core Snapdragon 801 processor clocked at 2.5GHz. There’s 3GB of RAM on tap as well as 16GB of storage (expandable via microSD card slot).
The rear camera is capable of capturing images at 16-megapixels while the front-facing shooter grabs memories at 8-megapixels. The phone measures 9.8mm thick with a 3,100mAh battery running Android 4.4 KitKat.
Interestingly enough, the ZTE Grand S3 has been on sale in China since January. At Mobile World Congress, however, ZTE announced that it’ll be coming to other markets. It’s priced at 2999 RMB (around $480) in its home country meaning it's probably a safe bet to see it debut elsewhere around that same price.
