This is interesting it’s a virtual supermarket on a train platform. Posters of supermarket shelves stacked with items are pasted onto platform walls. The user points their smartphone at the items they wish to buy and the goods are then delivered to their home address. The system has been successfully trialled at Seoul station in South Korea and could soon be coming the UK. Personally I can’t really see how it would work in our cramped, overcrowded tube stations at rush hour. What would be more annoying than rushing for a train and having to avoid not only the other commuters but also people standing with their phones doing their weekly shop.
