What if we create a unique new document that will be used as a passport and identity card that has a unique barcode which is checked by scaning and it is linked to a heavy protected website which has all informations about the owner of the document?

On that site, workers on the border write on the digital document the state which the owner of the document enters. We also could inmplent a option where they write the time period in which the owner should stay. And after the owner of the document leaves the state on the border exit workers do the same thing,scan barcode,open unique protected website and write down the exit date.  The website saves automatically all countrys you visit.

The member sites should only be able to enter via the barcode,same as onion sites in the dark web,hidden on the surface web and only enter able by those who have the onion link..

That is my idea,with that we avoid the passport expenses which are huge and it is just a piece of paper bassiclly.
