With the EU drone rules, several different IDs are circulating in the space, which are not always correctly differentiated. Here is an overview:
Operator ID (also: e-ID, UAS Operator ID, operator registration number)
This ID must be applied for at the Federal Aviation Office (LBA) and refers to the operator person or operator organisation of the UAS. It must be stored both physically and - if possible - digitally on the device.
Remote Pilot ID (also: RP-ID, Remote Pilot ID)
This ID is assigned to you as the pilot and is on your certificate of competence (= A1/A3 drone pilot licence) or remote pilot certificate A2 (large drone pilot licence).
A remote ID is an ID assigned to the UAS for remote identification. This can now be activated in some drone models. This works by entering the operator ID with a confidential check digit, which can be found in the operator profile at the German Federal Aviation Office.
The remote ID itself cannot be displayed, but with appropriate apps (e.g. Drone Scanner), you are then able to detect the drone up to 100 metres away on the app via Bluetooth/Wifi.
