Brands including WHSmith, Macy’s and Eat are using a new technology to deliver targeted messages to their customers’ mobile phones. ‘iBeacons‘ allow retailers to send discounts and offers straight to users who are in a specific location, without the need to open an app, scan a code or browse a website.
iBeacons use a Bluetooth connection to send data to mobile devices from stationary beacons. They use Bluetooth 4.0; a new format of Bluetooth that is built into many modern smartphones. The easiest way to understand how they work is to imagine them in terms of a traditional beacon: an object that sends a signal to communicate its location to those around it. As such, iBeacons only transmit small amounts of information from distances of between two inches to 50 metres.
