Here is another great scam, speaking of fraud. I remember something similar happening several years back where people would put up fake ATMs in public locations. People would put their cards in and enter their PIN. The ATM would tell them it was out of order and to try somewhere else. Later on the fraudsters would come back to collect the ATM and load all the read account numbers from the magnetic strips onto dummy cards that are easily purchased. Now they have a working debit card and your PIN and can empty your account at will. Pretty clever, eh? Well that is too high tech for some fraudsters. Here is what I read on another blogger's site.

Next time you use a bank machine, check closely to make sure it’s the real thing. Cops in San Francisco report that thieves are now installing fake overlays on banking ATMs. The fakes swallow your card, record your PIN, and report that they’re out of service; the thieves show up later to remove the fake overlay and harvest the cards and collected PINs.

As crimes go, I gotta had it to these scam artists: That takes work. It’s also quite successful, according to a story in last week’s San Francisco Examiner:

"Daly City nurse Elaine Flaherty’s ATM card was swallowed at a Washington Mutual bank in the West Portal district March 13, and within hours thieves had milked $4,000 from the card, using it from San Mateo to Los Angeles."

After poking around online a bit, I discovered a fascinating summary written up by Diebold — the leading manufacturer of ATMs — of the latest card-scamming techniques (PDF link). Some of the tricks are pretty low-fi. In some cases, the scam artists put a simple jamming device on the ATM’s card-slot that gets the card stuck inside. Then they put a fake sticker on the ATM saying that “if your card doesn’t work, try typing your PIN again”, which gives the shoulder-surfing thieves a chance to watch and remember it again. When you give up and walk away, they retrieve your card and withdraw all your cash. But some of the cons are more high-tech. In some cases, the criminals also put a fake 12-button keypad over the ATM’s real keypad; their fake records your PIN. And that artificial overlay for the entire machine, pictured above, is the ne plus ultra of this flimflammery.

It occurs to me that one of the reasons the fake overlays work is that real ATMs these days are often so shoddily designed that they already look fake. Sure, the ATMs embedded into the side of banks are usually pretty gleaming and high-tech. But the bank machines you find in crummy corner bodegas, composed of cheap aluminum and early-80s-vintage all-green video displays? Those things look like badly-assembled droids from the first Star Wars. No wonder it’s so easy to dupe banking customers. Using materials I’ve got lying around my kitchen, I could probably create a reasonable facsimile of the ATMs in most Manhattan bagel shops.

Again, my advice to you is to watch your back and be careful out there. It is a world of opportunists who don't have the morality that you might expect them to.
