What kind of phone can detect a beacon?

How are ble beacons used in wayfinding apps?
SmartRelay Location Anchors work like BLE beacons do in a Wayfinding App. In fact, The SmartRelay platform can also use beacons already deployed for Wayfinding. Asset tags running SmartRelay firmware act similar to a smartphone identifying its location based on its proximity to a BLE beacon.
