Aside from remote ID being used to find me and the drone, the fact we have to put our IDs into the data fields gives the CAA the ability to contact us at any time.
What if I put random data or silly names in the fields? Until 2028 it’s not mandatory so the answer may be different pre & post 1/1/28.
Are you asking for a friend?

(page 85)
the system shall perform a consistency check verifying the integrity of the full string provided to the UAS operator at the time of registration; in case of inconsistency, the UAS shall emit an error message to the UAS operator
New paragraph 12(A) will be inserted on 1 January 2028:
(12A) be capable of taking off only if the direct remote identification is functional and activated;]
So theoretically it should reject Mickey Mouse, will be trying that later, thanks.
I don’t mind admitting until 2028 I’d like to use random names or messages in the fields.
My drone needs nothing at present so I don’t need to add anything, random or not. 
Neither does mine but I’m not so bothered about someone knowing where I am. Large rucksack, controller in both hands staring into the sky looking for the drone, not hard to find 
I haven’t been able to find out if this all conforms to the GDPR regulation because at glance it doesn’t seem to?
From: Remote ID (RID) | UK Civil Aviation Authority
" Access to personal identifying data is restricted
Your Remote ID does not transmit any personal identifying data. Only the CAA and organisations we authorise can access details of the operator and remote pilot."
The CAA seem to think it doesn’t fall under GDPR. But this article seems to think otherwise.
(I think this has been posted previously in another thread on the subject.)
“Under the UK GDPR, enforced by the ICO, this broadcasted data constitutes personal data, as it can be geolocation linked to identifiable individuals, such as operators or those captured in footage.”
And you can read the ICO’s definitions and try to decide for yourself if the location of an individual constitutes “personal information” or allows indirect identification:
As yet, I have no beef with RID (I may or may not be participating as and when required) but my interpretation would be that knowing the location of an individual could allow you to visit that location and therefore identify them. Well, you could see what they look like - they wouldn’t have to give you any personal information - and while I myself think that doesn’t mean you know who they are, according to everything I’ve read, it is commonly taken to mean you can identify them.
My cynical view is that this has all gone too far for them to suddenly turn around and say, “Oh, shit! You’re right. This is all a huge GDPR nightmare. Better call it off.” Even if it actually is and they should. 
It does sound as if RID will contravene ICO guidelines but hey I’m sure we all know the CAA will get some sort of waiver so we can all stay safe and Rachel can tax Amazon delivery drones on a per mile basis as they’re powered by something which doesn’t stuff the planet!
Which app/website is that taken from?
You can download both the Drone Scout and Drone Scanner app’s from your fav app store - think that one is Drone Scout
Thanks, I’ve been using OpenDroneID
So here is an interesting one - seems that there is a limitation on iPhones that make these RID / Drone scanner app’s a bit limited as they cant use WiFi scanning or BT5 on them
So they can only pick up the BT beacon off the drone / controller
Screen shot from the Drone Scanner app - that is also from the company that makes the Rider Drone Tag unit that the app works with too for way better detection ( the tag unit is like €999! )
Drone Scanner.
