iBeacon is a new technology developed by Apple that uses Bluetooth low energy to enable proximity-based interactions between mobile devices and physical locations. It allows apps to push notifications and other data to users when they are near beacons placed throughout physical spaces like stores. Many retailers and venues are implementing iBeacon to improve customer experiences by connecting digital and physical worlds. While iBeacon was created by Apple, competing technologies are also being developed to bring similar proximity-based capabilities to Android and other platforms.
