[warning, severely low crypto relevance] OTOH, might as well carry around syringes filled with scopolamine (truth serum) if you intend on getting the real PIN. This stuff is actually legally obtainable from seeds of plants of the Datura family, as in Belladona (aka Nightshade), Stramonium (aka Jimson Weed) and a few others. They can be obtained from a variety of botanical catalogs (and probably in your backyard) and are highly toxic hallucinogens (only the bad ones are legal). I think their chemicals (atropine, hyoscamine and scopolamine) are also available as pharmaceuticals as they have some legitimate medical applications. I've heard from several sources that the US mil also checked it out (once upon a paranoid rumor that turned into an urban legend mayhap) as truth serum. Supposedly in certain S. American countries it has been used for quite some time in thefts. An added benefit is amnesia. Perfect way to gain people's PINs, pgp keys, home keys, non-essential organs, bank accounts, state secrets, astrological advice...). The antidote is legal in all countries except either Columbia or Brazil (can't remember which, ironically, it's the place where the most such thefts occur. The thieves must have a strong lobby.).
