# Fraud Dispute Mitigation

> Complete guide for mitigating fraud disputes with Paysight

<Info>
  **Paysight.io – Fraud & Dispute Mitigation**

  **Objective**: Reduce Visa/Mastercard fraud alerts (VAMP/TC40s) and chargebacks through layered prevention, authentication, and transparency. The measures below show how Paysight.io's CRM proactively lowers fraud alerts and chargeback risk. The percentages (↓) represent estimated reductions in TC40s/VAMP when each feature is applied.
</Info>

## Core Measures

### Network Tokens on Opt-in & Rebills (Visa & Mastercard)

<CardGroup cols={1}>
  <Card title="Network Token Implementation" icon="shield">
    Replace card numbers with Visa/Mastercard tokens for ongoing billing. Tokens are more secure, update automatically, and reduce fraud claims.

    **Expected Reduction**: ↓ \~30%
  </Card>
</CardGroup>

### 3DS in All Markets (Visa & Mastercard)

<CardGroup cols={1}>
  <Card title="3D Secure Authentication" icon="lock">
    Ensures a transaction is fully authenticated by the consumer. When approved, liability shifts to issuers and fraud flags are avoided.

    **Benefits**: Enhanced security and liability protection
  </Card>
</CardGroup>

### 3RI on Recurring Payments (Visa & Mastercard)

<CardGroup cols={1}>
  <Card title="3DS Requestor-Initiated Authentication" icon="refresh-cw">
    Use 3DS Requestor-Initiated authentication with device/IP/browser data. Creates a digital trail issuers can verify, reducing "no-auth" fraud flags.

    **Expected Reduction**: ↓ \~30%
  </Card>
</CardGroup>

### Visa Order Insight & CR 3.0 Compliance (Visa & Mastercard)

<CardGroup cols={1}>
  <Card title="Enhanced Transaction Transparency" icon="eye">
    Share metadata (IP, device, login history) with issuers. This transparency helps issuers confirm transactions, cutting friendly fraud disputes.

    **Expected Reduction**: ↓ 10–15%
  </Card>
</CardGroup>

### Consumer Clarity (Mastercard)

<CardGroup cols={1}>
  <Card title="Enhanced Billing Details" icon="credit-card">
    Shows enhanced billing details (merchant name, product, location) to cardholders via their bank app. Reduces "unrecognised charge" fraud claims.

    **Benefits**: Improved cardholder recognition and reduced disputes
  </Card>
</CardGroup>

### Fraud Scoring

<CardGroup cols={1}>
  <Card title="Real-Time Risk Assessment" icon="alert-triangle">
    Scores transactions in real time before capture. High-risk authorisations are blocked, preventing them from turning into fraud cases.

    **Benefits**: Proactive fraud prevention and risk mitigation
  </Card>
</CardGroup>

### Rapid Dispute Resolution (Visa)

<CardGroup cols={1}>
  <Card title="Automated Dispute Handling" icon="zap">
    Automatically refunds eligible disputes before they escalate to chargebacks. Improves user experience and prevents fraud alerts from escalating.

    **Benefits**: Faster resolution and improved customer experience
  </Card>
</CardGroup>

### CDRN (Visa)

<CardGroup cols={1}>
  <Card title="Chargeback Dispute Resolution Network" icon="shield-check">
    Intercepts unresolved Visa disputes and routes them to merchants for fast resolution, reducing ratios by preventing TC40 records also becoming TC15 (chargeback).

    **Benefits**: Reduced chargeback escalation and improved dispute resolution
  </Card>
</CardGroup>

### Clear Descriptors & Automated Care (Visa & Mastercard)

<CardGroup cols={1}>
  <Card title="Enhanced Billing Descriptors" icon="file-text">
    Billing descriptors match the website and include contact info. Automated care responses help resolve issues before cardholders contact banks.

    **Benefits**: Improved cardholder recognition and proactive issue resolution
  </Card>
</CardGroup>

## Expected Impact

<Success>
  **Compounded VAMP/TC40 Reduction: \~55–65%**

  * **Stronger issuer relationships**
  * **Higher dispute win rates**
  * **Improved compliance & cardholder trust**
</Success>
