In regulated gambling and high-risk markets, payment compliance isn’t optional—it’s survival. Strong Customer Authentication (SCA), 3-D Secure 2 (3DS2), and chargeback management are now core to keeping operations running, especially across the UK and EU.
Each of these systems adds friction and complexity. But ignore them, and you risk blocked transactions, fines, or excessive fraud. Done right, they protect your revenue and keep regulators off your back.
Understanding the Core Terms
Before diving into strategy, it’s critical to define the basics in plain terms. These are not interchangeable buzzwords—they serve different purposes in the payments flow.
SCA (Strong Customer Authentication)
SCA is a regulatory requirement under PSD2 in the EU and UK. It mandates that most electronic payments include two of three factors:
- Something you know (password, PIN)
- Something you have (phone, device)
- Something you are (fingerprint, face ID)
It’s designed to reduce fraud but often increases cart abandonment if poorly implemented.
3DS2 (3-D Secure 2)
3DS2 is the technical framework that enables SCA during card payments. It replaces 3DS1 with better UX and data sharing. Issuers can now use more contextual info (like device data, location, past behavior) to decide whether to challenge a transaction.
Think of 3DS2 as the tool, and SCA as the rule that requires using it.
Chargebacks
A chargeback is when a customer disputes a transaction with their bank or card issuer. In gambling, common reasons include:
- Claims of unauthorized use
- Disputes over bonus terms or withdrawals
- Attempted fraud (“friendly fraud”)
Chargebacks are costly—lost revenue, fees, and potential account bans from payment processors.
Balancing Compliance and Conversion
SCA and 3DS2 are necessary, but they also introduce drop-off risks. For operators, the goal is to remain compliant without killing conversion rates or spiking chargebacks.
What’s at Risk:
Poor implementation can block good players from depositing. Overly aggressive fraud filters can flag VIPs. Weak chargeback systems can sink your merchant reputation.
What Works:
Smart routing, exemption usage, and clear user communication help keep the balance right. So does aligning fraud prevention with customer service.
Key Optimization Tips
- Use exemptions wisely: Low-risk transactions under €30 may qualify. Too many exemptions = more scrutiny from issuers.
- Route high-risk traffic smartly: Use acquiring partners that support dynamic routing and adaptive 3DS logic.
- Preempt chargebacks: Give players clear, timestamped logs and strong transaction descriptors. Offer fast support resolution paths.
Compliance Settings to Review
Here are settings and policies every operator should evaluate as part of their payments strategy:
| Compliance Area | Setting to Review | Impact |
|---|---|---|
| 3DS2 Integration | Use of biometric/passive auth | Reduces friction, boosts UX |
| Fraud Rules | Thresholds for auto-block/flag | Avoids false positives |
| Chargeback Handling | Manual review vs auto-accept | Impacts win rate and cost |
| Descriptor Quality | Bank statement clarity | Reduces player confusion |
| SCA Exemptions | Limits and triggers set | Balances speed with risk |
These small setting changes often make a large operational difference—especially during high-volume periods.
Preventing and Managing Chargebacks
Chargebacks are a reality, not a rare event. The goal isn’t to eliminate them completely but to reduce frequency and improve your success rate in disputes.
Best Practices for Chargeback Defense
- Clear Terms: Make bonus terms and cashout policies easy to understand and accessible
- Accurate Logs: Maintain timestamped data showing user activity, deposits, and IPs
- Quick Response: Most card schemes require dispute responses within 7–14 days
- Staff Training: Make sure support teams know what red flags and resolution steps look like
Common Pitfalls
- Relying too heavily on automation without human review
- Poor transaction descriptors (“UNKNOWN CHARGE” causes panic)
- Inconsistent KYC checks leading to high fraud rates
Don’t wait for a wave of chargebacks to hit before reviewing your playbook.
