Suggested countermeasure: When true anonymity is requested, use the card ONLY ONCE, then destroy it. Makes the calls rather expensive, but less risky. Make sure you can't be traced back by other means, ranging from surveillance cameras in the vicinity of the phone booths to the location data from cellphones (because, as it's well-known but often overlooked, the cellphone networks know the location of every active phone).

Better yet, take another 10 minutes, get change from a laundromat, and use coins! Leather gloves, and avoid the cams (hats & sunglasses)! Of course, I'm assumin' a fixed payphone, so the cell phone worries, not to worry... -Max
