How AI Routing Works
Payment routing isn't just about cost — it's about maximizing approvals while managing risk and speed.
The Challenge
Traditional routing uses static rules:
- Route to cheapest provider
- Failover on decline
- Manual provider selection
This ignores critical signals: issuer geography, card type, transaction history, time of day.
Our Approach
ZenPays routing considers:
- Approval Probability - ML models trained on 100M+ transactions
- Cost Optimization - Real-time fee comparison
- Latency - Provider response times by region
- Risk Score - Fraud likelihood assessment
Results
- +12% approval rate improvement
- -18% processing cost reduction
- 40ms average latency
