But I'm provisionally calling BS on the "X-ray table." Based on (admittedly limited) experience with X-ray imaging, I don't believe that X-rays can read ink on playing cards. It would have to be a backscatter machine, which is even less discriminatory than a transmissive machine. Would need to see some evidence that this is possible.

If nothing else, the sheer size and bulk of such a machine renders the concept incredible. If I could build something like that, I wouldn't use it to cheat at cards, I'd sell it to the TSA!
