This seems like a misunderstanding of what eID is.

https://ec.europa.eu/digital-building-blocks/sites/display/D...

eID is a federated identity system that uses national electronic ID systems as the identity sources. That's useful especially for apps on the EU level, e.g. for customs, to submit what you're importing as a company.

In practice, I won't be able to use my phone as a replacement for my passport when traveling internationally. But I might be able to use my phone, in combination with my national ID card which has a NFC chip inside, to submit a government form in another EU country.
