goosed your card number

   While I was checking out at the gas station this afternoon I noticed a little device that the cashier referred to as the "Paypass." (which she also said no one could get to work right). This evening I saw a commercial for it that explained what it was. Apparently MasterCard has rolled out this new technology where all you have to do is tap your credit card against this device to pay. "no more swiping or giving your card to cashiers" (Mastercard.com) Since when is swiping your card too much of a hassle? Really, does that half second it takes to swipe a card take too long?
   I know that the magnetic stripe is easy to manufacture/copy for the fraud pros so there is a need for something new. But now I wonder if you have your pass-enabled card in your wallet, couldn't someone bump up against you with a device that would read your card info? Now the stranger that you think just goosed you is actually stealing your card number.
