Preventing criminals from using your credit card information for purchases online requires taking a few steps. First, make sure your payment processor offers secure methods of processing payments by encryption. Second, create strong passwords for your online accounts and use two-factor authentication whenever possible. Third, review your account statements for unfamiliar purchases and report any suspicious activity. Fourth, monitor your credit score to ensure unauthorized transactions aren't being reported to the credit bureaus. Finally, consider setting up a credit card “liberal usage limit” to stop potential thieves from making large purchases.
