How to Protect Your Business from Credit Card Fraud: For any business that accepts credit card payments, fraud is a constant threat. In 2020 alone, credit card fraud exposed businesses to over $130 billion in losses worldwide. As a business owner, you are responsible for protecting your customers’ payment information. Failing to do so erodes trust and exposes you to substantial financial risk.
In this article, we’ll provide some best practices for protecting your business from credit card fraud. Follow these tips to minimize risks and maintain a safe, secure payment process.
Tips to Protect Your Business from Credit Card Fraud
Understand the Most Common Types of Credit Card Fraud
The first step is educating yourself on the most frequent forms of credit card fraud:
- Counterfeit Fraud – Scammers use stolen card data to produce fake physical cards with encoded stripes. This is one of the most common types of in-person credit card fraud.
- Lost/Stolen Card Fraud – Fraudsters use cards that were physically lost or stolen from the rightful owner. This is more common in establishments where cards leave customers’ possession like restaurants.
- Card Not Present (CNP) Fraud – Fraudsters use stolen card numbers to make purchases online, over the phone, or by mail order. This is the most common type of credit card fraud overall.
- Identity Fraud – Scammers open fraudulent accounts using stolen personal information. The cardholder is unaware as the statements go elsewhere.
- Friendly Fraud – Customers dispute legitimate purchases as fraudulent to avoid paying. Although not criminal per se, this results in losses for merchants.
Understanding these common fraud types helps you identify areas of vulnerability in your business.
Assess Your Business’s Level of Risk
All businesses accept some level of fraud risk when taking credit card payments. Conduct an assessment to determine your level of exposure:
- High Risk Industries – Some sectors like jewelry, electronics, luxury goods, and adult entertainment attract more fraud attempts.
- High Average Ticket Prices – Fraudsters often target larger purchases that maximize their potential gain.
- Heavy CNP Transactions – Fraud is 4-5 times more common in card-not-present versus in-person purchases.
- International Business – Cross-border payments increase fraud likelihood due to less oversight.
- Rapid Growth – Fast scaling businesses can outpace their fraud prevention systems.
Knowing your inherent risk levels allows you to prioritize fraud prevention appropriately.
Implement Robust Card Acceptance Policies
Well-designed policies strengthen your first line of defense against credit card fraud:
- Require CVV codes for card not present sales. Never process an order without one.
- Align to industry standards like PCI DSS for data protection and tokenization.
- Verify signatures on card present transactions and check ID for large purchases.
- Set maximum purchase sizes and order counts from a single card within a time period.
- Allow only qualified staff to process payments after thorough training and background checks. Enforce dual custody for large orders.
- Mask card numbers on receipts and truncate electronic logs. Only record necessary data.
Clear, enforced card acceptance policies limit vulnerabilities in your systems and processes.
Maintain Contact with Your PaymentProcessor
Your payment processor is a trusted partner in fraud prevention. Maintain close contact with them:
- Report suspicious transactions to your processor immediately upon discovery. Acting quickly limits losses.
- Discuss rule customizations like setting caps on purchase amounts or high-risk geographic blocks.
- Seek additional fraud tools like address verification, device identification, buyer authentication, and machine learning algorithms.
- Review declines regularly to spot patterns and optimize acceptance rules.
- Query chargebacks to understand where your fraud events originate.
Your processor has valuable insights from seeing billions of transactions. This expertise strengthens your prevention strategy.
Utilize Fraud Prevention Technology
Modern tools provide automated assistance detecting and blocking fraudulent transactions:
- Address Verification Service (AVS) – Confirms the billing address matches the card issuer’s records during processing.
- CVV verification – Validates that the 3-digit code on the card matches the processor’s records.
- 3D Secure – Adds a step requiring cardholder authentication via password or biometric ID for online purchases.
- Device fingerprinting – Analyzes computing device characteristics to flag high-risk ones.
- POS systems – Sophisticated terminals scan cards for tampering, enable chip-based EMV security, and block fraudulent prepaid cards.
- AI and machine learning – Advanced algorithms identify transaction patterns that signal fraud in real time.
Layering these technologies provides robust protection from various fraud vectors.
Monitor Transactions and Statements Diligently
Ongoing monitoring enables early fraud detection before losses compound:
- Review reconciliations daily and investigate any anomalies between deposited amounts and your receivables ledger.
- Confirm large transactions with customers via phone or email to verify legitimacy.
- Establish transaction caps and review any that exceed thresholds.
- Watch for duplicate charges spaced hours or days apart from the same card.
- Check statements weekly for unknown charges and call your processor if any seem suspicious.
- Flag gaps in sequential payment batches as potential diversion of funds.
Consistent reconciliation and monitoring practices limit losses by identifying fraudulent activity quickly.
Educate Staff on Red Flags
Train staff to recognize signs of suspicious purchases:
- Requests to ship high-value products internationally
- Orders shipped to an address far from the billing address
- Multiple cards used for a single purchase
- Identical purchases made minutes apart from the same IP address
- Transactions with altered receipts or manually entered card numbers
- Hesitation, confusion, or anger when asked for ID or CVV code
Empowered staff can stop fraudulent transactions at the point of sale before losses occur.
Limit Credit Card Data Retention
Following best practices around payment data storage is critical:
- Delete card numbers immediately after payments process. Never store the full number.
- Mask data like showing only last 4 digits of card numbers.
- Encrypt stored data and limit employee access via passwords and permissions.
- Truncate records to only retain essential payment details needed for business operations.
- Secure physical terminals and printouts. Never leave cards or receipts openly accessible.
- Destroy unneeded documents securely by shredding.
Minimizing stored payment data greatly reduces your security vulnerabilities.
Purchase Fraud Liability Insurance
Consider fraud liability insurance as another layer of protection. These policies cover costs related to data breaches and fraudulent transactions.
Evaluate levels of coverage for:
- Investigations and legal services
- Notification and card reissuing
- Fraudulent transaction reimbursement
- Lost income and operating expenses during shutdown
- PR crisis management
- PCI fines or assessments
Having adequate coverage ensures fraud incidents don’t put you out of business.
Respond Quickly to Suspected Fraud
If you uncover a data breach or fraudulent transactions:
- Call your payment processor immediately to halt processing and begin an investigation.
- Notify affected customers and card issuers per breach notification laws.
- Reset online account passwords used on compromised devices.
- Work diligently with investigators to determine root causes and affected data.
- Assess technical vulnerabilities that enabled the breach and address them.
- Update fraud prevention protocols to prevent repeated events.
- Document the incident thoroughly including steps taken in response.
A swift, thorough response demonstrates your commitment to customers and regulators.
