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

There are several steps you can take to protect yourself from credit card fraud. First, make sure your credit card is encoded when you make an online purchase and always check your monthly statements for any fraudulent charges. You should also make sure that you haven't shared your credit card details with any unauthorized person and keep your contact information up to date on your account. Furthermore, ensure that your online account with the credit card company is properly locked and secured, and consider enabling an identity theft protection service.
