Automated Teller Machine customers now robbed wirelessly without knowledge: The University of Texas at Austin police have a compelling page that shows how a skimmer (which scans ATM cards before they're inserted into the ATM) and a wireless camera in an innocuous position nearby can steal a card and the PIN. The skimmer reads the magnetic stripe; the camera can see the PIN being entered.
The thieves park nearby and retrieve the information wirelessly. This is reminiscent of last month's story of a wireless Israeli post office money heist.
It may be just me, but after years of being warned about shoulder surfers in the 1980s and 1990s, I often cover my hand when entering a PIN on a phone or ATM. I guess my paranoia pays off.
Also, I only go to one bank's ATM machines, which are uniform. I think I'd notice a weird add-on.
