A fraud score is a numerical value that indicates the risk level of a transaction or user action, helping businesses determine whether to approve, review, or decline a payment.

The scoring typically ranges from 0 to 99, with higher scores indicating greater risk. Let’s find out more about fraud scoring and what you can do to lower yours.

How Fraud Scoring Works

Fraud scoring operates like a sophisticated risk assessment system that evaluates every transaction in real-time. Think of it as your business’s digital security guard, analyzing multiple data points simultaneously to protect against fraudulent activities.

Data Collection and Analysis

The process begins when your fraud prevention software collects transaction data. The system examines various elements, including:

– Transaction amount and timing

– Customer’s device information

– IP address location

– Payment details

– Historical purchase patterns

Each of these elements receives a specific weight in the scoring calculation. For example, a transaction from a data center IP address might add +10 to the risk score, while suspicious port activity could trigger additional points.

Scoring Mechanism

The system typically uses a scale from 0 to 99, where higher numbers indicate greater fraud risk. Here’s how a typical scoring framework operates:

Real-Time Decision Making

Modern fraud scoring systems employ both rule-based evaluation and machine learning algorithms to make instant decisions. The system can:

– Automatically approve safe transactions

– Flag suspicious activities for manual review

– Trigger additional verification steps

– Decline high-risk transactions

Dynamic Authentication

When a transaction falls into a medium-risk category, the system can automatically implement additional security measures. This might include:

– Requesting two-factor authentication

– Triggering identity verification

– Requiring additional documentation

This layered approach helps maintain security while minimizing friction for legitimate customers. The beauty of modern fraud scoring lies in its flexibility – you can adjust thresholds and rules based on your risk appetite and business needs.

Key Risk Factors Affecting Your Score

Your fraud score is influenced by multiple data points that fraud prevention systems analyze in real-time. Understanding these factors helps you better manage your risk profile and reduce false declines.

Identity Indicators

The system evaluates various identity elements to verify customer authenticity. A customer’s digital footprint plays a critical role in determining their risk level. Key factors include:

– Email address age and reputation

– Phone number verification status

– Billing and shipping address match

– Social media presence and activity

Transaction Patterns

The way a transaction occurs can significantly impact the fraud score. The system examines:

– Purchase amount and frequency

– Time of purchase

– Geographic location and velocity

– Payment method used

For example, a transaction made from a location thousands of miles away from a previous purchase within a short timeframe will trigger a higher risk score.

Device and Network Signals

Your fraud prevention system carefully analyzes technical indicators that could signal fraudulent activity:

Historical Data

Past behavior patterns significantly influence fraud scores. The system examines:

– Previous transaction history

– Known fraud associations

– Chargeback history

– Account age and activity patterns

For instance, if an email address appears on spam blacklists or is associated with previous fraudulent activities, it will contribute to a higher fraud score.

Remember that these factors’ weights can vary based on your business type and risk tolerance. Modern fraud scoring systems use machine learning to dynamically adjust these weights based on emerging fraud patterns and your specific business needs.

INCREASE YOUR APPROVAL RATIO

Managing and Reducing Risk Scores

As an online business owner, you can actively influence your transaction risk scores and reduce false declines. Here are a few proven strategies that help maintain security while maximizing approval rates.

Best Practices for Lower Risk Scores

Implementing proper verification processes significantly reduces risk scores. Focus on:

– Collecting accurate customer data during checkout

– Implementing address verification (AVS)

– Using card security codes (CVV)

– Maintaining consistent business practices

Smart Transaction Management

Your transaction patterns directly impact risk assessment. Consider these approaches:

Authentication Strategies

Modern authentication methods help verify legitimate customers while keeping fraud scores low:

– Implement 3D Secure 2.0 for high-risk transactions

– Use biometric authentication when available

– Enable two-factor authentication for account changes

– Collect device fingerprinting data

Monitoring and Optimization

Actively manage your fraud prevention system by:

– Regularly reviewing declined transactions

– Adjusting risk thresholds based on patterns

– Creating whitelists for trusted customers

– Maintaining clean customer data

Handling “Risk Match” Declines

When your payment processor returns a “transaction declined due to risk match” message, it indicates that multiple risk factors have combined to exceed your system’s risk threshold.

This decline message typically appears when the transaction exhibits several suspicious patterns rather than a single red flag. For example, a customer might be using a new email address, connecting through a VPN, and attempting a purchase significantly larger than your store’s average order value.

To effectively handle these declines, start by examining your transaction logs for specific risk indicators that contributed to the high fraud score. Look for unusual patterns like mismatched billing and shipping addresses, suspicious IP addresses, or velocity checks that show multiple failed attempts.

These details often reveal the root cause of the decline. If you notice that a legitimate customer triggered the decline, you can temporarily adjust your risk rules or create a customer-specific whitelist to prevent future false declines.

Consider implementing a step-up authentication process for transactions that fall into this “risk match” category. Instead of outright declining these transactions, you might set up a system that requests additional verification from customers whose orders trigger moderate risk scores.

This approach helps balance fraud prevention with revenue optimization, especially for high-value transactions that naturally trigger more risk indicators. Remember that each declined transaction represents both a potential fraud prevention success and a possible lost sale from a legitimate customer, so finding the right balance necessary.
