- FIGHT BACK! BY DAVID HOROWITZ
-
- Someone Looking Over Your Shoulder
-
- Do you ever have that creepy feeling that you're being watched
- -- that someone you can't see is looking over your shoulder? It may be
- more than just your imagination, especially if you're using an ATM card
- at your bank or gas station.
-
- Thieves are out there watching, often with telescopes or cameras
- with long telephoto lenses. They are watching your hands punch your
- personal identification number into the terminal. The next step is to
- make a copy of your ATM card. That's easier than you may think. All
- they need is your account number and a device that imprints that number
- on the magnetic strip of a blank credit card.
-
- Those account numbers are plentiful. There are trash cans and
- waste baskets full of them around every automated teller machine.
- People just throw them away, not realizing that a clever thief can use
- the numbers printed on those receipts to manufacture duplicate ATM
- cards. Passers then use those cards to drain cash from victims' bank
- accounts until either the money is gone or the card access is canceled
- by the bank.
-
- I've seen these watchers, these so-called "shoulder surfers," at
- work in New York City. It was a couple of years ago at the Port
- Authority Terminal, where I was shooting a story on phone fraud. My
- cameraman and I saw "surfers" spying on callers as they punched their
- calling-card numbers on pay phones. Those numbers were later sold on
- the street for $20 to $50 apiece.
-
- More recently, two enterprising thieves in New York installed a
- small video camera over an ATM to record people as they made their
- transactions. They also provided a handy tray to dispose of the ATM
- receipts. They put the information together and ripped off the banks
- for $1.4 million in only six days.
-
- This is also happening at service stations where people use
- their ATM cards to buy gas. The terminal is usually mounted on a post
- near the pumps in plain view of anyone nearby. All the surfer has to do
- is watch for those customers who throw their gas receipts in the trash,
- and they have the makings of a counterfeit card. Arco is now lowering
- their ATM terminals so the customer's body blocks the view of the
- keypad.
-
- One device that might foil shoulder surfers is the kind of
- digital keypad we have on our news room security system. There are no
- numbers printed on the keys. Instead, the person at the door presses a
- button that reveals lighted num- bers behind the keys in random order.
- That number pattern is different every time the button is pushed and
- can be seen only by someone standing directly in front of the keypad.
-
- Here are some tips to avoid being ripped off: -- Memorize your
- PIN number. Don't write it on your card or carry it in your wallet.
-
- -- Don't choose obvious number sequences, like 1-2-3-4, your
- address or your birth date.
-
- These are the first numbers a thief would try if he or she had your
- wallet.
-
- -- Cover the ATM keypad with your hand or body when entering
- your access code.
-
- -- Take your receipts with you. If you don't want them for your
- bank records, at least throw them away elsewhere.
