What is the minimum range you can setup Proximity Beacons or Stickers for both Android and iOS devices? I was hoping it would be able to trigger events at the same distance as NFC tags (basically tapping on a Beacon to trigger specific actions).
Also, can one Beacon be used to trigger different actions at different distances? In other words, one type of notification can be sent to a user far away and by using the same beacon, a different notification is sent when he taps his device on the beacon?
Keep in mind, that I want to apply this to both Android and iOS devices.
