In China, Amazon's store of the future' is already open!

Amazon showed off its automated Go grocery store concept at the end of last year, but a few months later postponed any actual shop openings. One Chinese startup, however, is steaming ahead with its own version - and has already opened a handful of staffless convenience stores where customers open the door and pay the bill with their phone. Last month, the startup opened its first outlet in Shanghai after a few months of testing in its home city, Zhongshan, in southern China. Although small, the Bingobox store stocks hundreds of items - including a small selection of fresh foods. Pictures and more details here.
