In the fast-evolving digital payments ecosystem, merchant acquiring has become more complex—and more critical—than ever. The traditional approach of static KYC processes and reactive risk assessment no longer aligns with the needs of today’s fast-moving, compliance-heavy financial environment.
Whether you’re a bank acquiring millions of UPI transactions daily, or a fintech scaling new merchant verticals, the ability to onboard, classify, and monitor merchants intelligently and in real time has become a competitive edge.
At CARD91, we believe the future of merchant acquiring is not only digital—but AI-driven.

The Limitations of Traditional Acquiring Workflows

Conventional merchant onboarding is often manual, document-heavy, and time-consuming. Risk scoring is rule-based, limited to surface-level checks, and rarely dynamic. Merchant categories (MCCs) are broad, leading to ineffective classification and higher chances of risk exposure.
As a result:

1. High-risk merchants may slip through the cracks.

2. Legitimate businesses face onboarding delays.

3. Acquirers struggle with fragmented data and outdated risk models.

Credit Line on UPI is integrated into UPI apps, giving users immediate access to pre-approved credit without requiring additional applications or cards. The system supports flexible repayment options, including pay-later models and EMIs, offering a user-friendly, fast, and secure experience. Credit limits are personalised to match each user’s financial profile, making the service highly adaptable to diverse customer needs.

Reimagining Merchant Acquiring with AI

AI introduces a new way to approach acquiring—one that’s data-rich, real-time, and contextually adaptive. Here’s how:

AI

1. AI-Powered Onboarding: Speed Meets Compliance

Using AI and OCR technologies, KYC documents can be auto-extracted, verified, and cross-validated with public data sources. This reduces onboarding time from days to minutes while staying aligned with RBI compliance norms.

At CARD91, our onboarding engine helps banks and fintechs verify merchants faster, flag inconsistencies early, and drastically reduce manual intervention.

2. Real-Time Risk Scoring for Every Merchant

Every merchant poses a unique risk profile. AI models assess multiple data signals—business type, transaction patterns, geographic indicators, even device data—to assign dynamic risk scores.

Unlike rule-based systems, AI can:

  • Detect hidden connections between merchants and known fraud rings.
  • Score new-to-business merchants based on industry-wide behavioral benchmarks.
  • Trigger real-time alerts for suspicious spikes or chargebacks.

3. Intelligent Merchant Classification

Gone are the days of generic MCC-based grouping. AI enables fine-grained merchant segmentation based on actual business behavior and transaction attributes.

Why does this matter?

  • It allows better tailoring of MDR rates and settlement terms.
  • Helps acquirers predict future revenue potential.
  • Supports personalized engagement strategies for each merchant segment.

4. Continuous Monitoring and Adaptive Risk Controls

AI doesn’t stop at onboarding. It evolves with the merchant. Real-time surveillance models detect unusual behavior—like sudden refund spikes or off-hours activity—and trigger adaptive controls like temporary limits or manual review.

This enables acquirers to protect themselves while maintaining business continuity for legitimate merchants.

What This Means for Banks and Fintechs

For financial institutions looking to scale merchant acquiring without increasing operational overhead, AI offers scalability, security, and strategic clarity. It:

  • Accelerates go-to-market for new merchant verticals.

  • Strengthens compliance posture.

  • Reduces fraud and operational risk.

Improves trust among merchants through smoother onboarding and support.
