** Important! The tracer-scanner app is to be used only in combination with our tracers. Without our tracers this app will not be of any use. To make full use of the app, a code sent by us is required. Without the code only the battery can be read. **
Our tracers detect each other when they are within 1.5 meters and then store the device number in a list. By scanning a tracer with the tracer-scanner app, tracers that have been in range can be identified.
