Beacon FAQ

Q. Is it possible to send notifications to iPhone users through my beacons?
 

A. iBeacon/Core Location principles defined by Apple require users to opt-in into proximity experiences.
They typically do it by downloading a beacon-enabled app and enabling Location Services/Bluetooth/Notifications. 
There are some already existing apps for iOS that can listen to Eddystone URLs - for example, Chrome by Google for iOS; but it shows Physical Web links only in the Widget and users have to activate it.
