Lenovo is the next company to get into cashier-less convenience stores, following Alibaba, Walmart-owned Sam’s Club, JD, and Amazon. The hardware maker launched a cashier-less store in Beijing last week that sells Cup Noodles, juice boxes, and other small snacks.

To enter the “Lenovo Lecoo Unmanned Store,” customers wave to a tablet with a camera, which uses facial recognition to identify their account profile. Then, like Amazon Go’s system, customers can browse, pick up the items, freely exit, and the charges will be automatically deducted from their mobile payments accounts.
