yeah it surprised me how easy it can be.
after posting this I started to wonder how close the hacker would have to be in order to read the victim's card. In the boonies I don't see a lot of people walking up that close and not being noticed. Of course everyone goes to the big bad city from time to time.
I must say wrapping the card in aluminum foil reminds me of those who wear foil on the head in order to keep the aliens from knowing what they are thinking.
