Payment gateway modules for e‑commerce and physical retail acceptance. Merchant settlement logic with real‑time settlement transparency.

5. Compliance & Security Integration of KYC/AML compliance systems for onboarding and transaction monitoring. Real‑time risk and fraud detection modules as part of the AI stack. Secure data storage, encryption, and regulatory compliance frameworks (e.g., PCI, GDPR).
6. User Interfaces (Mobile & Web) Mobile wallet applications for iOS and Android. Responsive web dashboard for account management and administrative controls. UX design focused on simplicity, security, and onboarding ease.
7. Administration & Reporting Admin dashboard for support teams, analytics, and compliance teams. Real‑time reporting capabilities for all transaction and wallet activity.
