A Carrefour hypermarket in Lille, France has become the first supermarket in the world to install Philips' new 'indoor positioning system'. This system uses LED technology to function as a satellite navigation tool for shoppers, giving them in-store directions to help them find items on their shopping list.
The store uses Philips' Visible Light Communication Technology, wherein each light produced transmits a unique code that can be picked up by the camera on shoppers' smartphones. The code can then be read by the Carrefour iOS mobile app. This helps shoppers figure out where they are and where they need to go in the massive 7,800 square meter shop floor.
The indoor positioning system is a great example of technology being used to enhance and fine-tune the retail shopping experience.
