Reducing credit card acquisition time by over 75% through Decentralized Digital Identity

How we redesigned the credit card application journey using bank-verified credentials, eliminating the need for existing customers to refill forms.

Overview

Problem

Customers faced a fragmented onboarding experience. Even legacy bank clients had to manually re-enter all personal data and re-upload documents on the credit card web portal due to a lack of backend integration. This friction resulted in a 17-minute application process, leading to high drop-off rates and a redundant user journey for over 80% of applicants.

Solution

We developed a Decentralized Digital Identity (IDD) solution within the bank’s app. The system allows users to transform their verified bank data into ‘Digital Credentials.’ Through a seamless deep-link integration, users authenticate via facial biometrics and instantly export their verified attributes to the credit portal. This ‘Single Source of Truth’ approach allows users to review and update data in real-time, reducing the application time to just 4 minutes.

My Contribution

I led the design phase following initial research; performed a comprehensive desk research of discovery artifacts to validate findings and ground the interface execution in proven user data.

As a Product Designer for the past 2 years, I bridged the gap between complex blockchain concepts and the bank’s Design System. I led the end-to-end design of the credential issuance and management flows, collaborating daily in an Agile/Scrum environment with POs, developers, and stakeholders. I also facilitated Design Critiques to ensure consistency and oversaw Value Perception Research, where the solution was validated by real users as a high-value alternative to traditional forms.

Research

To validate the proposed digital identity solution and understand how users navigate the experience, we conducted an exploratory qualitative study.

We interviewed eight participants who had recently applied for a credit card through the bank’s website. Each session lasted approximately 60 minutes and followed a semi-structured interview script that explored user expectations, navigation patterns and perceived value of the new flow.

Participants observed the facilitator navigating the prototype while providing instructions, reactions and feedback throughout the session. This moderated walkthrough helped us uncover friction points, misunderstandings and opportunities to improve the overall flow.

Key user pain points

The research revealed several friction points in the existing card application process:

  1. Long and repetitive forms
    Users reported frustration with the number of required fields. Completing the full form often took more than 10 minutes, increasing irritation and the likelihood of abandoning the process.
  2. Authentication failures
    When biometric verification failed, users felt uncomfortable and uncertain about the process. In many cases this interruption led them to abandon the application.
  3. Loss of entered data
    Participants described situations where the page refreshed unexpectedly and all previously entered information was lost, forcing them to restart the process.
  4. Date selection difficulties
    The calendar component made it difficult to select specific dates, particularly when navigating across years.

 These findings reinforced the need to reduce form friction and streamline identity verification through reusable digital credentials.
