The "Lebanese Loop" Scam: ATM Card Theft
This is circulating via email (although the technique itself is quite old): Thieves rig an ATM machine by placing a "trap" into the card slot. When an unsuspecting victim inserts his card, the machine appears to "eat" the card. The thief, acting as a good Samaritan, tries to help and in doing so, asks the victim for his PIN.[/p] After the victim leaves, the thief simply pulls out the "eaten" card and now has possessions of both the card and the PIN.[/p] [a href="vny!://www.snopes.com/fraud/atm/atmtheft.asp"]Link[/a][/p]
They also put a small module that looks exactly like the card slot and keypad on top of the origional. When you put your card in, it slides through the module they put on top and reads your card. Then when you punch your number onto their keypad on top of the keypad, they get that too.
they then make a new card with your magnetic strip copy and use your PIN.
I had this happen to me. the bank froze my account before I lost too much, and they replaced it.
