There are several steps you can take to prevent criminals from using your credit card information for purchases online. First, sign up for accounts with websites that store your credit card information and enable two-factor authentication. This will allow you to quickly spot any suspicious activity related to your account. Second, keep your credit card number and expiration date confidential, and do not share it with any unauthorized parties. Third, review your statements regularly and notify your credit card company of any suspicious activity. Finally, be sure to always use secure websites when making purchases, as they have encrypted data transfer methods to protect your credit card information.
