China's leading e-commerce player JD's largest unmanned supermarket opened in Xiongan New Area during the Labor Day holiday, according to the firm's public WeChat account on Tuesday.

The 246 square-meter supermarket contains multiple cutting-edge technologies, including biological recognition, artificial identification and internet of things, allowing customers to check prices on electric screens and pay their bill by facial identification.

Last year, JD signed agreements with Chinese real estate developer China Overseas Land & Investment Ltd, with a goal to build hundreds of unmanned convenience stores in China's biggest cites.

Currently, the unmanned supermarkets have opened in Beijing, Tianjin, Yantai, Dalian, Suqian, Xi'an and Changchun.

Based on the latest master plan for Xiongan New Area to develop it into a modern city that is green, intelligent and livable, with relatively strong competitiveness and a harmonious human-environment interaction by 2035.

Some high-tech companies and business giants such as Alibaba, Tencent and Baidu will set footprints in the place.

This year, Xiongan will start 13 projects, including a high-end lab for national defense technologies of Tsinghua University. The total investment of these projects will reach over 60 billion yuan ($9.47 billion), according to thepaper.cn.
