Survey to inform design

I conducted an anonymous survey with  
seven participants to gather insights on their attitudes towards social banking and expectations with the onboarding process.

Survey insight: 71% & 57%   of the users were ready to share their debit card details and link bank accounts respectively

Insight: 100%   of the users were ready to share mobile number with banking apps

Insight: 57%   of the users responded neutral to the idea of social banking  upon asking they mentioned that they were not sure what social banking meant

Survey insight: 100%   of the users preferred biometric authentication to signing up (finger print, face ID)

Usability Testing

To better understand the onboarding experience for mobile banking apps,
I conducted usability testing with
five participants.

User testing insight:Only 1 out 5  participants swiped the slideshow  to read the apps selling points or features

User testing insight: Only 2 out 5  participants chose to add their debit card. Others just skipped it!

User testing insight: 4 out 5  participants said that they prefer the Wise app’s onboarding experience

User testing insight: Visual Delight  Despite the extended duration of Wise app's onboarding process, users remarked that its animations and visual aesthetics made the experience feel seamless.

Research Analysis

①
App’s feature slideshow are important

57.1% of users were unsure about social banking because they didn't understand it.   

And during testing, only 1 out of 5 participants read the app's explanation.

②
Making Debit Card Details Optional: Enhancing User Flexibility

71.4% of users were fine with sharing debit card info, and 57% were okay with giving bank details.   

However, during testing, only 2 out of 5 participants added their debit cards during onboarding.

③
Importance of Biometric Authentication

100% of users preferred biometric authentication during sign-up. Testing revealed that all users successfully added either Face ID or fingerprint authentication (Android).   

However, one user failed to receive a verification code via email, preventing them from completing sign-up on PayPal, highlighting the importance of biometric authentication.
