Apple iBeacons were first introduced with iOS 7 and they use BLE (Bluetooth Low Energy) to access and push information through an app on your smartphone by listening to signals around you. Essentially, the beacon uses your phone to locate you, but it has the potential to do so much more.
Apple devices have Siri, and Google has Google Now. Both are artificial intelligences designed to act as personal assistants. She can make appointments for you, set alarms or reminders, and she can answer questions like which restaurants are nearby. Siri works, but she's not the best. Microsoft has made sure of that.
