Executive Summary
A regional bank with 340 branches partnered with TechDigitally to deliver a secure mobile banking experience competitive with neobank challengers — without compromising PCI-aware controls or customer trust.
Industry Context
Retail banking customers expect instant transfers, spending insights, and biometric login as standard. Incumbent banks that lag on mobile experience lose share to digital-first competitors — making secure, polished app development a board-level priority.
The Challenge
The legacy mobile app averaged 2.9 stars, lacked real-time notifications, offered no unified design system across iOS and Android, and generated excessive call-center volume for routine transactions.
Our Solution
We built native-feel cross-platform flows, integrated biometric authentication, real-time push notifications for transactions and fraud alerts, in-app support chat handoff, and a spending insights dashboard fed by categorized transaction data.
Approach & Methodology
Security and UX progressed in parallel: threat modeling workshops, penetration test remediation, design system build, then phased feature rollout with beta cohorts from high-digital-adoption branches.
