The capstone: Design your own virtual card product
Your assignment is to design and spec a real-world card product. You don’t need to write code. You need to demonstrate full-stack product thinking.Step 1: Choose a use case
Pick one:- Subscription control cards for Gen Z mobile users
- Business expense cards for African SMEs
- USD cards for Nigerian students paying for global exams and tuition
- A virtual card API to help platforms issue cards to their own users
Step 2: Define the product brief
Answer these questions:- Who is the user, and what problem does the card solve?
- When and how is the card issued?
- How is it funded (USDT? Wallet?)
- What limits, fees, and lifecycles apply?
- What happens when a transaction fails or is refunded?
- What metrics define success?
Step 3: Design the experience
Sketch or describe:- The card view in the app (UI elements, what is shown)
- The top-up flow
- A failed payment experience
- A support dashboard for the ops team
- Decline messages or refund journeys
Step 4: Compliance and operations
Include:- KYC tiering logic
- Any PCI considerations
- Chargeback and refund policies
- What you would log for support and audit
- What training your support team needs
Step 5: Final write-up
Prepare your concept as one of the following:- A detailed PRD
- A product blog post or article (recommended)
- A pitch deck for internal stakeholders
- A Notion page for internal documentation
