What is card-not-present (CNP) fraud?
Card-not-present (CNP) fraud occurs when a fraudster makes a payment without physically using the victim’s payment card. This typically happens in online, phone, or mail-order transactions, where the merchant cannot verify the card in person. Cybercriminals often exploit stolen card data, account credentials, or social engineering techniques to authorize transactions.

CNP fraud is a growing concern as e-commerce and digital payments continue to rise, and it remains one of the most persistent threats for financial institutions, merchants, and consumers.

How does CNP fraud work?
Fraudsters use a combination of methods to execute CNP attacks:

  • Stolen card data: Purchased on the dark web or obtained through phishing, data breaches, or skimming.
  • Account takeover (ATO): Using stolen login credentials to make purchases or change account details.
  • Social engineering: Trick victims into providing card numbers or verification codes.
  • Automated fraud tools: Bots can test card numbers in bulk to find valid combinations for online purchases.

Once the fraudster has the necessary information, they can complete online purchases, request refunds to new accounts, or sell digital goods, often leaving merchants and cardholders responsible for the loss.

Why is CNP fraud a concern for financial institutions and merchants?
CNP fraud bypasses traditional physical card security, like EMV chips, making it harder to detect. This results in:

  • Increased chargebacks and financial losses.
  • Erosion of customer trust and loyalty.
  • Greater operational costs for fraud detection and remediation.
  • Difficulty distinguishing legitimate transactions from fraud without sophisticated tools.
Practical Ways to Prevent Card-Not-Present (CNP) Fraud
As digital transactions grow, CNP fraud remains one of the most persistent threats for financial institutions and merchants. Below are practical, industry-proven strategies that help reduce risk while keeping the customer experience smooth.

  1. Strengthen customer authentication: Use strong, multi-factor authentication and apply intelligent step-ups only when risk signals require it.
  2. Use device and behavioral intelligence: Validate trusted devices and monitor behavioral patterns to detect unusual or suspicious activity.
  3. Apply real-time transaction risk scoring: Analyze signals like device fingerprinting, IP velocity, and geolocation to approve, step up, or block transactions.
  4. Adopt dynamic security features: Replace static CVV with dynamic or one-time card security codes to prevent misuse of stolen credentials.
  5. Optimize merchant controls: Encourage tokenization, enforce AVS/CVV checks, and strengthen verification for high-risk merchant categories.
  6. Improve customer communication: Provide warnings for unusual activity, share scam-avoidance tips, and offer simple in-app controls.
  7. Monitor fraud end-to-end: Use continuous fraud monitoring across channels to connect signals and act early on compromised credentials.
