How to Protect your Business from Credit Card Fraud

 

What is credit card fraud?

Credit card fraud is the unauthorized use of a credit card or credit card details to make purchases or withdraw funds. It affects both consumers, who may face stolen funds or identity theft, and businesses, which may bear financial, reputational and operational losses.

Credit card fraud targets businesses through fraudulent transactions, chargebacks, or the exploitation of weak security protocols. Such fraud may use stolen cards, counterfeit cards created using cloned card data, or digital data that’s been obtained from account takeovers, phishing or hacking. Credit card fraud is a critical issue for businesses that requires robust preventive measures to minimize financial loss, safeguard reputations and build customer confidence. After a review of the types of fraud your business faces, this guide will outline the ways you can prevent fraud.

Common types of credit card fraud targeting businesses;

1. Card-not-present (CNP) fraud

This fraud occurs in transactions where the cardholder isn’t physically present, such as online, over the phone or by post. For example, a high-value online order is placed using a stolen credit card, but the business does not verify the cardholder’s identity. The legitimate card owner disputes the charge, leading to a chargeback.

2. Friendly fraud

This is when a customer falsely disputes a legitimate transaction by claiming they never received the goods or didn’t authorize the purchase in the first place. For example, a customer orders a product, receives it, but is not happy with it. Rather than go through the hassle of making a return they simply contact their bank to file a chargeback claiming non-delivery.

3. Counterfeit cards

Skimming devices can be discretely added to ATMs or point-of-sale terminals and used to copy card data. This can then be embedded into fake cards. For example, a criminal uses a counterfeit card in-store, leaving the merchant liable when the bank identifies the transaction as fraudulent.

4. Account takeover

Hackers gain access to customer accounts through phishing emails or data breaches. They use the data they gain to make unauthorized transactions, often changing the login passwords to lock out the original user. For example, stolen data is used to access a customer’s account and place multiple orders. This bypasses security measures due to using stored payment details from the account.

5. Refund fraud

Lenient return policies can be exploited by using stolen payment methods to purchase items and request refunds to the fraudster’s own account. For example, a scammer may purchase high value electronic devices with a stolen card and then request a refund to a different card.

6. Merchant fraud

This involves fake businesses processing fraudulent transactions, often as part of a money-laundering scheme. For example, an online store is set up to process stolen card payments and it disappears before customers are aware their card has been used.

How to Prevent Credit Card Fraud as a Merchant

Although the fraud landscape is constantly changing, much of the fraud that takes place relies on exploiting weaknesses in the prevention and protection strategies that businesses have implemented. 

Effective fraud prevention requires an approach that combines technology, policies and employee training. In this section we outline the measures you should have in place.

1. Use advanced payment gateways

Payment gateways with fraud detection features built into them can flag suspicious transactions in real time using machine learning and AI to identify them and keep pace with the changing landscape.

Features may include:

  • Address Verification Systems (AVS) to verify that the billing address matches the cardholder's address.
  • CVV checks to ensure the customer has the physical card.
  • Algorithms to monitor transactions in real time and flag any unusual patterns or activity identified.

2. Implement 3D Secure protocols

3D Secure adds an extra authentication step to online transactions, reducing the likelihood of card not present fraud. Examples include Verified by Visa and Mastercard SecureCode.

3. Monitor transactions

Your payment gateway may include the ability to use analytics to identify unusual patterns or known high-risk factors, such as:

  • Orders from certain countries
  • Multiple purchases made in quick succession
  • Mismatched billing and shipping addresses

4. Train employees

Equip staff with the skills and knowledge so that they can recognize suspicious activities. This may include:

  • Customers refusing to provide ID for large purchases
  • Suspicious card behavior, such as declined attempts followed by approval on a different terminal

5. Ensure PCI DSS compliance

The Payment Card Industry Data Security Standard (PCI DSS) establishes guidelines for securely handling cardholder data. Compliance requires businesses to implement robust security measures such as encrypting sensitive information, maintaining secure systems and monitoring access to payment data. Non-compliance can result in fines and leaves your business open to increased risk of fraud.

6. Define strict refund policies

Implementing strict refund policies is a critical step in fraud prevention.

  • You should clearly limit refund eligibility to verified transactions by requiring a proof of purchase, such as an original receipt or transaction ID.
  • Your refund timelines, conditions and acceptable reasons should be clearly stated in your policy.
  • In addition, you should have a return verification process in place, such as matching billing information and confirming the original payment method.

7. Regularly update security systems

Outdated software is vulnerable to attacks. Ensure any software you use has patches applied promptly and is using encryption to protect sensitive data. Source
