iBeacon is based on Bluetooth low energy proximity sensing by transmitting a universally unique identifier[4] picked up by a compatible app or operating system. The identifier and several bytes sent with it can be used to determine the device's physical location,[5] track customers, or trigger a location-based action on the device such as a check-in on social media or a push notification.
