Yes.

This is actually something that should be looked into, and would solve many of the problems that currently exist.

As noted, forensic light systems, which go through the whole range of frequencies, exist and are used in other areas. And there could be a company or service that just provides the scans.

I also thing microscopic, or very large, scans be simultaneously be done to authenticate of the card. I have people email microscopic images or huge scans, and I can identify real from fake from those.

There are also systems that mathematically calculate the gloss by shining slightly off from head-on light at the surface, and systems for measuring the opacity (how much light goes through the material) These could be parts of the scanning systems.

In the future, cards may be able to be identified, authenticated and checked for alterations just via scans. And the great thing about scans is many people all over the place can look at them.
