My passport is in the hands of an embassy right now, because of a visa application. I paid more to expedite the process but, just in case the passport doesn't make it back to my hands in time, I would like to know if I can go from France to Spain (short stay) without the passport with me.
I have seen this question and I've read the answer but it seems to conflict with the following quote in the EU website:
Going to another EU country during my short-term visit – less than 90 days
If you have entered an EU country with a Schengen visa, you can travel throughout the Schengen area for as long as your visa is valid, and for a maximum of 90 days during an 180 day period. You will not need a separate visa for each Schengen area country and you will not need to show your passport at each internal border.
I have a photocopy of my passport biometrics page, if that helps.
