Duly not that some examination can be done with the card in the holder. For example microscopy, infrared, opacity and blacklight. I've successfully used a microscope and black light on cards in PSA holders.

Though, it's important to remove the card for proper investigation-- but it would be cool, and very much possible, for some alterations to be scientifically identified with the card still in the holder. A method for this could be developed.

For the record, I firmly very don't believe modern technology can or will be able to make passable counterfeits (meaning counterfeits that will pass experts using proper identification methods).

The scans could further be used to identify future alterations, regrades, provenance etc and demonstrate that professional holders are not required. Further the scans allow the cards to be examined by experts without the need for the of the in-person card. Some sort of computer/AI software would identify the card and its history.
