Traditional credit scoring has always relied on a narrow set of data points: credit card history, loan repayments, and formal banking activity. But what if we could assess creditworthiness using the rich tapestry of everyday transactions?

The UPI Advantage

India's Unified Payments Interface (UPI) processes over 13 billion transactions monthly, representing trillions of rupees in economic activity. This data tells a story that traditional credit bureaus miss.

Transaction Consistency Score

We analyze payment patterns to understand financial discipline:

\\\`python def calculate_consistency_score(transactions): """ Measures regularity of transaction patterns Higher scores indicate predictable financial behavior """ monthly_counts = group_by_month(transactions) coefficient_of_variation = std(monthly_counts) / mean(monthly_counts) return normalize(1 - coefficient_of_variation) \\\`

Cash Flow Health Index

Understanding income vs. expenses reveals financial stability:

  • Inflow Stability - Consistent income sources
  • Outflow Management - Controlled spending patterns
  • Buffer Maintenance - Healthy balance over time
  • Emergency Resilience - Ability to handle unexpected expenses

Relationship Network Score

Your transaction partners matter. We analyze:

  • Diversity of counterparties
  • Longevity of business relationships
  • Transaction reciprocity patterns
  • Network credibility scores

Privacy by Design

All analysis happens with explicit user consent and follows strict data protection principles:

  1. Data Minimization - We only access what's necessary
  2. Purpose Limitation - Data used solely for credit assessment
  3. User Control - Full data portability and deletion rights
  4. Transparency - Clear explanation of all data usage

Validation Results

Our pilot programs show promising results:

| Metric | Traditional Scoring | OpenCredit | |--------|--------------------| -----------| | Coverage | 30% of population | 85% of population | | Default Prediction | 78% accuracy | 82% accuracy | | Time to Score | 2-3 weeks | Real-time |

Next Steps

We're continuously improving our algorithms through:

  • Community feedback and code review
  • Academic partnerships for validation
  • Pilot programs with cooperative societies
  • Regular bias audits and fairness testing

Join us in building the future of inclusive credit assessment.
