After coming across a few reports of devices that can read the chip on your credit card right through your wallet without touching you, I discovered it is true that wrapping it in aluminium foil will seriously reduce the odds of it being read.
So I suppose I could place my cards in a little aluminium foil envelope in my wallet. Of course, they could still pick my pocket the old fashion way.
