imagine you walk into a store. strangely enough, you see no staff (店员) inside. you pick up things and prepare to wait in line and pay.
but even more strangely, there is no cashier (收银员) at all. so what has happened to this store?
well, you may h**e entered tao café, a cashless store created by chinese e-commerce giant alibaba. in july, the public got to see the store for the first time at alibaba’s taobao maker festival in hangzhou.
the 200-square-meter store sells drinks, fast food and snacks. it can hold up to 50 shoppers at a time. to enter and shop, people only need a smartphone with a taobao app and an alipay account (账户).
by scanning their taobao qr code (***), shoppers are followed with cameras for facial recognition (面部识别). the store has also digitalized (数字化) all goods and their placement on the shelves. so when shoppers pick up goods, the system (系统) will be able to “watch” and “remember” their selection.
when shoppers are ready to le**e, they don’t wait in line to pay. instead, they go through two checkout (结账) doors. then the bills will automatically (自动地) be paid with a taobao account connected to alipay.
according to alibaba, the checkout machines can recognize goods even when shoppers put them in pockets or bags. so it is almost impossible to steal things from the store.
tao café is not the only cashless store in china. a 24-hour store with no staff called bingobox opened in shanghai in june. to enter the store, shoppers scan a qr code on wechat or alipay.
but unlike the tao café, they h**e to scan another qr code to le**e the bingobox.
tao café the only cashless store in china?
do we need to buy things from tao café?
are paragraphs 4 and 5 mainly about?
**：学&科&网z&x&x&k]
you think the cashless store will be more and more popular in china?
