Gov app uses the "Chave Móvel Digital", which can be used in the browser, as well as in a variety of mobile apps. This CMD can also be used to digitally sign documents. I believe it's still possible to use the physical card with a reader for many things. I think some services still don't work with the CMD. Recently, I had to ask for changes to my car's document, and it seems it's only possible with the card itself.
