The only time a screener would see below that would be if there was an alarm item there. (software programing to determine this). The advantage is that there is almost no place for a person to hide an item of any material on them, short of swallowing them.
The above "latest proposal" won't work tomorrow. And even with the machines set at the "advertised" levels of "safe", there are ways to still hide items on person that are well short of swallowing thems. Can we find a bookie to handle bets on when the first "celeb" body images will show up in the tabloids or other publicized domain.
If we get lucky with these applications, we'll catch ourselves some idiots, some unfortunates and a few terrorists acting like members of an "advance team". If we get unlucky, we are, to some degree, going to find ourselves passively twiddling our thumbs until the next "grandiose" terrorist plot comes aviation's way (or gets shifted elsewhere). In the air or on the surface, communicable disease or improvised chemical explosions may come to mind and the current applications, even if tweaked, will do little except fight the last fight.

That's what I would think too.
