Can you tell me how to prevent criminals from using my credit card information for purchases online?

To prevent criminals from using your credit card information for purchases online, you should always use a secure payment system, such as PayPal or a digital wallet. Additionally, you should always log out of unused sessions and make sure your computer or device has the latest security updates installed. Additionally, you should monitor your statements closely for any unexpected purchases and contact your bank or credit card provider right away if you notice something suspicious.
