Launching a Digital Wallet App for E-Pay

Executive Summary

E-Pay Pakistan set out with an ambitious goal: to dominate the consumer digital payments sector. They needed a world-class, highly scalable digital wallet capable of handling millions of micro-transactions daily. Karsaaz Solutions delivered an end-to-end white-label wallet solution tailored to their market needs.

The Challenge

Building a mass-market digital wallet presents unique engineering challenges:

• Scalability: The platform had to support high-velocity, low-value transactions, especially during peak retail hours.
• Security: Protecting consumer funds against sophisticated cyber threats and unauthorized access was paramount.
• User Experience: The app needed an intuitive, frictionless UI/UX that users across all demographics could easily navigate.
• Ecosystem Integration: It required integrations with utility companies, telecom operators, and existing banking networks (1Link).

Our Solution

We leveraged our robust Karsaaz Digital Payments Framework to accelerate the launch.

Architecture & Features:

• Microservices Backend: Built using Node.js and Golang, ensuring ultra-low latency for payment authorizations.
