Case Study
Fintech Mobile Banking App
Harness is a mobile banking platform that enables users to conduct secure financial transactions from anywhere. The client needed a robust, user-friendly banking app for iOS and Android that could handle real-time transactions, account management, and cross-border payments — all while meeting fintech security and compliance standards.
InterCode developed the full mobile application using React Native, providing a unified codebase across both platforms with a focus on transaction security and seamless user experience.
