(Yicai Global) Oct. 25 -- Self-service retailer Jian 24 has received USD4.5 million (CNY30 million) in angel-round financing from BlueRun Ventures and RedPoint Ventures, internet media outlet jiemian.com reported.

Jian 24's A-series financing is also under way, with investors "from first-tier dollar funds, and currently more than half of the amount is targeted," said Lin Jie, Jian 24's founder and chief executive.

Jian 24's first unstaffed convenience store, built with a variety of leading technologies, has officially gone into operation. Its users can leave directly upon selecting their purchases after installing an app or scanning a QR code upon entry.

To ensure the accuracy of visual recognition, the shop allows in no more than 10 customers at a time.

"The 2.0 version store will be available at the end of this year. Jian 24 is expected to open 30 to 50 outlets in Shanghai by the first half of next year, Lin said.
