To prevent criminals from using your credit card information for purchases online, you should use a secure and reputable payment processor for all your purchases, keep your account information and password secure and confidential, and routinely check your account activity for unauthorized charges. Additionally, you should use two-factor authentication whenever available, and be aware of any phishing attempts or suspicious activity associated with your account. Lastly, you should also take advantage of any fraud protection the credit card company offers.
