Imagine a time when you walk into a shop to do some shopping, and there are no sales staff, no tills and no way to pay with cash. That may seem futuristic, but some of these things are happening at the present time, with a view to being the stores of the future.
For example, some companies in China are looking to revolutionise retail by taking advantage of e-payment technologies. One, Bingo Box, is offering unmanned convenience stores that require a mobile app to enter, and then you pay at a self-service checkout using a mobile wallet like Alipay or WeChat.
