Understanding Card Shield

What is Norton Card Shield and why should I use it?

Norton Card Shield helps you manage where merchants store your payment details. It analyzes your transaction activity to identify potentially stored information and guides you through the removal process.

You should use Card Shield if you want to:

  • Gain more control over where your payment information may be stored online.
  • Reduce your exposure to fraud, data breaches, or account takeovers.

Who can benefit from using Card Shield?

Anyone who wants more control over where merchants store their payment information online can benefit from using Card Shield. It helps reduce exposure to account takeovers or potential breaches.

Will Card Shield affect my card or account access?

No, Card Shield does not change your card account itself. It only helps you review and manage where your payment details may be stored.

How Card Shield Works

How does Card Shield identify where my billing information may be stored?

Card Shield analyzes your transaction activity to identify merchants who are likely to have your payment information on file. This information can include your billing address or card number.

How does Card Shield scan my transactions?

After you link your financial accounts, Card Shield reviews your transaction history. It examines the last 12 months of transactions to identify merchants that may have stored your payment information.

Does Card Shield access all my past transactions when I link a credit card account?

No, Card Shield typically reviews only the last 12 months of your transaction history. It also reviews any new transactions made on your connected credit card account going forward.

How does Card Shield determine which merchants likely store my information?

Card Shield uses various signals to estimate whether a merchant likely stores your payment information. These signals include whether a transaction was online or in person, along with a review of the merchant’s privacy policy and other relevant indicators.

How does Card Shield determine a merchant's security risk?

Card Shield obtains a merchant’s security risk rating from a third-party vendor. This vendor uses artificial intelligence and data analytics to identify and prioritize vulnerabilities and assess the merchant’s overall cyber health with its proprietary methodology.

Can Card Shield remove my card details?

Card Shield guides you through the removal process with step-by-step instructions. It helps you take action, but does not automatically remove the details for you.

Usage and Limitations

Why should I remove my billing information from a merchant?

Many data breaches have stolen billions of records in recent years. These breaches often include SSN, names, and addresses. Removing saved billing details from merchants you no longer use or trust reduces your exposure to fraud or data breaches.

What are the prerequisites for using Card Shield?

To use Card Shield, you must link your financial accounts within the product. This allows it to review your transaction history.

What are the regional and transaction history limitations of Card Shield?

Card Shield has the following limitations:

  • It currently supports only U.S.-based merchants. It will not work with international merchants.
  • It typically reviews only the last 12 months of transaction history from linked accounts, along with new transactions.
