I have a digital ID card on my desk right now. It does not need to be stored on the phone which has all the means necessary to communicate with the card. In fact, if it was in a slightly different form factor I could even put it physically into my phone as it happens to have a built-in smartcard reader, which would still be a more reasonable solution than apps since then it wouldn't be strongly coupled with a complex device that can break or be compromised in various ways (some of which can't be solved with attestation) and would maintain a clear separation between what's mine and what's government's. What exactly would I, as a user, gain by muddling that distinction?
