Indeed, sloppy science journalism and the article seems repetitive. Anyway, supply chain anti-tamper is generally a good and useful thing. I think this is the higher-tech version of the vacuum packed bag of beans/rice idea. The issue not mentioned is one I've encountered in other similar projects which is false negatives cause by "creep" in plastics and general thermoplastic movement. We had a near-UV scanner that could map the surface of a test object (sensitive circuit boards) down to a few wavelengths, but it was too damn accurate. Go back and scan the same object a week later and stuff (like solder joints) has moved naturally. That doesn't work when things are in transit for weeks with vibrations and temperature variations.
