[ Want to unlock the ZTE Grand S3? Just let the handset's front-facing camera scan the veins in both eyes. ZTE and EyeVerify have teamed up to offer the Eyeprint ID feature on the Grand S3. The scan could be used in the future to verify mobile payments and for other applications. As it turns out, everyone has a unique pattern of veins in their eyes. The ZTE Grand S3 was unveiled Sunday at MWC after being launched domestically in China on January 17th. It's already won an IF Design Award 2015 for ZTE’s 'minimalist design philosophy'. ZTE does plan on using the Eyeprint ID on other models. The feature is considered to be more secure than a fingerprint scanner since both eyes are scanned. The ZTE Grand S3 features a 5.5-inch screen with a resolution of 1080 x 1920. Under the hood is a quad-core 2.5GHz Snapdragon 801 CPU with 3GB of RAM inside. The phone is equipped with 16GB of native storage and a 64GB microSD card is available for those who require additional memory. A 16MP camera is on back and an 8MP "super selfie snapper" adorns the front of the model. The 3100mAh battery keeps the lights on and Android 4.4 is pre-installed. The phone does support LTE connectivity. The ZTE Grand S3 is available in China, priced at the equivalent of $478 USD. ZTE has sold over 5 million units of the Grand series, including models sold in the U.S. such as the ZTE Grand S, ZTE Grand Memo, ZTE Grand Memo 5S, ZTE Grand S2, and the ZTE Grand X Max.
