FinTech Case Study:
From Concept to Delivery for a Transaction-Based Communication Platform
Our client, a fintech innovator developing a transaction-based communication platform, asked us to enable merchant–customer engagement through standard payment transactions—without needing personal data (PII). This groundbreaking concept positioned banks and card issuers as facilitators of real-time messaging while preserving customer privacy.
Concept & Discovery
Challenge
The client sought a seamless, non-PII communication channel built into digital banking and merchant systems.
The goal: enable loyalty, messaging, offers, analytics — all without sharing personal data—leveraging existing payment flows.
Approach
- We conducted comprehensive discovery workshops to refine technical feasibility and integration points.
- We aligned with the client on business drivers—privacy, speed to market, analytics insights, and simplified integration.
- We defined a lightweight integration model suitable for card-issuing and merchant-acquirer platforms.
Solution Design & Architecture
Platform Mechanics
- We designed a transaction-based communication layer: every payment triggers a reversible messaging event, enabling data-free engagement.
- We developed a flexible content management dashboard, offering rule-based content delivery (e.g., loyalty, offers, messaging) tied to transactional context.
User-Centric Features
Real-time two-way messaging, fully anonymous.
Built-in offer & loyalty management per SKU, merchant, or individual transaction.
Embedded feedback mechanisms like NPS - Net Promoter Score, directly from transaction events.
Technical Highlights
Ensured minimal disruption to existing banking SDKs and merchant systems.
Prioritized privacy-by-design, eliminating PII exposure.
Built a robust analytics engine for behavioral and transactional insights.
Development & Implementation
Team Composition
We assembled a cross-functional squad drawn from its expertise in Fintech, AI, and Integration Services: Project Managers, System Architects, Backend and Frontend Developers, UI/UX Designers, QA Engineers, and DevOps Specialists.
Development Process
We followed a structured agile methodology, with iterative sprints and ongoing client feedback loops.
We prioritized essential features: transaction-triggered messaging, integration SDKs, and offer management tools.
We ensured privacy standards through architectural isolation and anonymized payloads.
We implemented lightweight SDKs for web and mobile integration.
Quality Assurance & Deployment
- We undertook comprehensive testing across secure rails and banking environments.
- We coordinated phased rollout with fallback and rollback plans to ensure zero customer disruption.
- We delivered user training and documentation for the client.
Delivery & Results
Outcome Achieved
- Deployed a novel communication channel embedded in payment infrastructure, enabling merchant–customer interaction without personal data.
- Simplified integration: minimal code changes for banks and merchants.
- Enabled workflow enhancements: merchants can now launch real-time offers, collect feedback, and track engagement—all anonymous.
- Provided deep analytics—transactional data now drives richer business insights.
