Beacons can help support omnichannel experiences by connecting online and offline data. They allow retailers to provide a unified brand presence across channels like websites, mobile apps, and physical stores. Beacons transmit signals that can be detected by smartphones to track customers' locations within stores and enable experiences like navigation, analytics, and personalized communications. While beacons face challenges like app integration and privacy concerns, their low cost and support across mobile platforms make them a promising technology for improving customer journeys across online and offline retail channels.
