iBeacon technology allows apps to pinpoint a user's location using Bluetooth signals. Small iBeacon devices broadcast a unique ID to nearby phones, enabling location-aware apps. Opportunities include hyper-local retail offers, interactive museum tours, and home automation. Limitations include needing the app, Bluetooth, and location services to be enabled, as well as many iBeacons for accurate positioning. An example described a shopper receiving product offers from an H&M app based on her location in the store.
