After three years, EuroShop is back! Suppliers from all over the world are meeting in Düsseldorf at the leading retail trade fair. There are exciting technological innovations on display - holograms that replace mannequins, shopping carts that follow shoppers "at their heels," robot shopping companions and much more. Many innovations fascinated us, but not all of them were convincing. It remains to be seen which trends will translate into profitable business models. In any case, the trade show is worth a visit!
