Nexa: Reimagining Mobile Banking with AI

In an era where mobile banking is becoming increasingly prevalent, with over 28 million UK adults using banking apps, I identified an opportunity to enhance the banking experience through AI-powered conversational interfaces. Nexa was conceived as an intelligent banking assistant designed to help busy professionals and tech-savvy adults manage their finances more efficiently.

Challenge

While mobile banking adoption continues to grow, users often struggle with:

  • Time-consuming navigation through multiple screens for simple transactions

  • Complex processes for routine financial tasks

  • Growing need for personalized financial insights

  • Balance between convenience and security concerns

Market Analysis

Research into existing solutions revealed successful implementations like Bank of America's Erica, which handled over 1.5 billion interactions. However, a significant gap existed in addressing security concerns and building trust, especially among older users.

Research Process

Survey Insights

I conducted a survey with 36 respondents aged 26-40 in the UK to understand their attitudes toward AI in banking. Key findings included:

  • Most respondents were tech-savvy and familiar with AI assistants

  • Strong interest in AI for routine banking tasks

  • Significant concerns about privacy and security

  • Desire for personalized financial planning tools


Understanding users

Based on the user research and the insights generated, I created user personas that captured the essence of the ideal users of this product. This helps in creating personalised experiences that solves their pain points.

Using the How Might We (HMW) framework, I developed solutions focused on:

  • Conversational interface supporting both text and voice interactions

  • Facial recognition integration for enhanced security

  • Real-time transaction monitoring and insights

User Interface Design

I created a modern, clean interface that:

Prototyping

The prototype was developed using:

  • Figma for UI design and basic interactions

  • ProtoPie for advanced voice interaction simulation

  • Integration of facial recognition concepts

Testing & Validation

I conducted usability testing with tasks including:

  1. App signup process

  2. Voice command interaction

  3. Transaction history review

Key feedback highlighted:
