Call me cynical, but I'm pretty sure the refusal to give resident EU citizens actual physical proof of their "digital identity" is enable more Hostile Environment shit to perfectly legit UK residents.
How are landlords, etc, going to check this "digital identity"? Website (that's slow or keeps going down), or phonecall (that keeps them on hold)?
That's one level. It's all extra hassle when dealing with an EU citizen compared to a UK one, even if the website is working.
And then, given this is coming from the Cummings government, we can also be pretty sure data of landlords, etc using the website will also be collected. How do you think that will mix with the Tory party's previous plans to "name and shame" companies which employ foreign workers?

That was 2016, but I doubt that thinking has vanished. Sideways pressure put on landlords and other companies providing services to furriners? Who knows.
Sounds mad, but I cannot think of any other rational explanation for not issuing a physical card linked to the digital ID, and this government has form.
