In the past, cities used to have 4 functions – dwelling, recreation, work and transportation but as the fourth revolution moves forward, these boundaries are now becoming interchangeable. With the integration of connected devices in retail spaces, businesses can leverage the real-time data from IoT sensors to know when a product is about to go out-of-stock or customer activity on a specific day. With the adoption of this technology, retail stores are becoming more experience-based retailers. The store is now a space of entertainment that is made into a special experience for the customers.
