P3Finder - Phase based 3D RAIN RFID tags Finder
This demo app presents a three-dimension locational information on multiple RAIN RFID tags on radar maps. First map describes the relative distance between a RFID handheld antenna and tags in horizontal view. The second map describes the elevation of tags relative to the antenna.
You may include this positioning feature in your own RFID app via P3Finder SDK. The SDK manual is available at https://rflocus.github.io/P3Finder-SDK-Manual-Android/. For more information on the SDK, please contact p3finder@rflocus.com.
