EDIT: Figured it out - You need an iOS app as well. There's one that can locate and display iBeacon info here: https://itunes.apple.com/us/app/locate-for-ibeacon/id7387090...
I'm a little disappointed. The use case I had in mind was: Customer walks into a store with iBeacons and is given a notification that they tap which installs the app. I suppose this would have too much potential for abuse though.
