Credit Card Skimmers

If you're not familiar with a credit card skimmer, its a device that can secretly record the magnetic strip on the back of your ATM or credit card and your PIN.  These devices are generally composed of a card reader and fake keypad or camera.

To help protect yourself against these devices, follow the advice below:
  • With your free hand cover the keypad.  This will prevent others and a camera from being able to see your PIN as you enter it.
  • Carefully look for something out of the ordinary or out of place (e.g. a part that is sticking out too far) on the ATM.
    • The quality of these skimmers will vary from simple to complex.  The complex ones can be very difficult to detect visually.
  • Watch out for people who might be hanging around the ATM for a long time.
  • Check your account balances of your financial accounts on a regular basis (at a minimum of once a month).

ATM Card Traps

ATM card traps are devices that are designed to capture your debit or credit card so it can be retrieved and abused later.  These devices are created out of a thin piece of wire, string or tape that is inserted in the card slot on an ATM, the obstruction will prevent the machine from being able to eject your card.  After you leave in frustration, a thief will come in and retrieve your card.

To help protect yourself against these devices, follow the advice below:

  • If your card gets trapped stay with the card and call your bank or the credit card company right away and cancel the card.
  • Make sure to have the phone number to your bank or the credit card company in your cell phone before something like this happens
