# Import participant data

* Keep the participant list up-to-date and prevent mistakes.
* Use your system to add tracking devices (GPS trackers, transponders, decoders, track boxes) to specific athletes. Synchronize the tracking devices with RACEMAP.
* Manage participant information such as name, race number, key, status (DNF, DSQ, DNS), start- and finish time, and much more.

### Import and visibility rules

Import of RACEMAP tracking keys: Only those keys are imported, that belong to this RACEMAP event.

To show a participant in the visualization its device id must be known. The visibility of different devices depends on the activation of predictive tracking.

| Device id               | Predictive tracking |                     NO predictive tracking                    |
| ----------------------- | :-----------------: | :-----------------------------------------------------------: |
| IMEI of GPS tracker     |          ✔️         |                               ✔️                              |
