  • Keep your check card in a safe place and give it the same consideration you would cash or checks.
  • If you receive a replacement check card, be sure to destroy your old card.
  • Sign the back of your check card with permanent ink.
  • Unless you initiated the phone call, never provide your card number over the phone.
  • Do not include your check card number in an email.
  • Use only secure websites, indicated by a lock symbol in the address bar next to the URL, when shopping online.
  • Utilize Verified by Visa or MasterCard Securecode for an additional layer of security when shopping online.
  • Always log off from a website and close your browser after making a check card purchase.
  • Keep transaction receipts in a safe place or destroy them.
  • Select a unique PIN that is not connected to your everyday activities or life, such as birthdays or anniversaries.

Skimming is a popular method for criminals to steal your check card data from the magnetic strip on the back of your card. Skimming devices are typically smaller than a deck of cards and attached in close proximity to an ATM or automated fuel dispenser card reader. When using ATMs and automated fuel dispensers, be aware of any add-on device that may look like it is not a factory-installed card reader.
