Hypothesis
After analyzing interview insights, users’ pain points, and goals:
A mobile application could be a good solution for this problem because of the following reasons:
- It can provide easy access, and users can use it anytime, anywhere to reload their card balance.
- It can keep users informed about any important information regarding their balance, offers, and reminders.
- User will be able to track their balance usage, charges, and transfers.
