What if the specs check the cards for secret marks or markings?
No worries! In the manuscript, I suggest you actually encourage people to examine the cards for any kind of marks or markings. If they really want to pursue this theory, they can study and feel every micron of every card’s surface, front or back, and they won’t find any bumps, crimps, pinpricks or other marks or markings because there are none to be found! It still works.
