The retail sector is changing because the ‘customer journey’ is very different than before. Customers no longer come to a store without knowledge, but use the Internet as a source of information. In a store they want information to be more thorough and tailored to their needs. Retailers must be innovative in order to distinguish themselves from online stores. Creating a unique customer experience is crucial. In addition, information about these customers is of strategic importance to the retailer. Many retailers therefore already work with sensors, beacons and data analysis or are planning to do so in the short term. Internet of Things can help retailers work more efficiently, reduce costs, get more income from existing solutions and really make the customer king.
