How to Prevent Card-not-Present (CNP) Fraud

Why Preventing CNP Fraud Matters

CNP fraud directly impacts:

• revenue loss from fraudulent transactions
• chargebacks and associated fees
• increased processing costs
• operational time spent resolving disputes

Without the right controls in place, even a small number of fraudulent transactions can create a significant financial and administrative burden.

Step 1: Use Strong Customer Authentication (SCA)

Authentication is your first line of defence.

For online transactions, this includes:

• 3D Secure
• one-time passcodes
• biometric verification

These methods confirm that the person making the payment is the genuine cardholder, reducing fraud risk and shifting liability away from your business.

Step 2: Avoid Handling Card Data Directly

The more your business interacts with raw card data, the higher your risk.

Manual processes such as:

• taking card details over the phone
• writing down payment information
• storing card details internally

increase both:

• fraud exposure
• PCI DSS compliance requirements

The safest approach is to keep sensitive card data out of your environment entirely.

Step 3: Secure Telephone (MOTO) Payments

Telephone payments are one of the biggest weak points in CNP transactions.

Traditional methods:

• rely on verbal card details
• offer no authentication
• leave the business fully liable

A more secure approach allows:

• customers to enter their own details
• authentication to be applied
• card data to bypass your systems

This significantly reduces both fraud risk and compliance burden.

Step 4: Implement Basic Fraud Checks (But Don’t Rely on Them Alone)

Tools like:

• AVS (Address Verification Service)
• CVV checks
• velocity controls

can help flag suspicious activity.

However, they do not confirm cardholder identity, nor do they remove liability. They should support your strategy — not be your only defence.

Step 5: Monitor Transactions and Set Rules

Ongoing monitoring helps catch fraud early.

Look for:

• unusually high-value transactions
• multiple payments in quick succession
• mismatched billing and delivery details

Setting rules and alerts can prevent fraudulent transactions from being processed in the first place.

Step 6: Use Secure Payment Methods for Remote Transactions

Not all payment methods carry the same risk.

Lower-risk approaches include:

• authenticated payment links
• Open Banking payments
• secure digital checkout flows

These methods reduce reliance on manually entered card data and improve transaction security.

Step 7: Reduce Chargeback Exposure

Chargebacks are often the end result of CNP fraud.

To reduce them:

• ensure transactions are authenticated
• keep clear records of transactions
• use secure payment flows
• communicate clearly with customers

The more evidence and security you have, the stronger your position.

Step 8: Train Your Team

Fraud prevention isn’t just technical.

Staff should understand:

• the risks of handling card data
• how to identify suspicious behaviour
• when to escalate concerns

Simple awareness can prevent costly mistakes.
