Easy in a "stable" situation like an airport with all the material.
Harder in anything less than a perfect environment.
Now what about between non-friendly countries.
In a warzone. On a road checkpoint. For the random checks at the gate of the plane or in the middle of the boarding process (for flights to the US they check it both at the gate and on the "boarding platform" now).
At least the paper things provides "something" when that's all you have to ID someone.
