Research Insights


Giving a child a card instead of cash can help them (and parents) monitor their spending, as well as teach them about money and banking.

Prepaid card for children?

Think of them like pay-as-you-go mobiles. Your child can't spend beyond 0€, forming a 'safe' barrier so they can never go over their limit.

Take the control

All cards I've researched as the best on the market come paired with a smartphone app which allows you as the parent and your child to see what and where money is spent.

A second insight for parents is that you can also control how your child uses the card. For example, you can temporarily stop the card, you can set spending limits and monthly allowances, and in some cases you can restrict operation with validations

Education value

As the cards can be used in shops, online and for cash withdrawals it's a good way to teach your children the basics of how banking works before they move onto a bank account when they turn 18.
Also, most of the cards have apps where your child can visualise how much they're spending, how much money they have left on the card and where they're spending. They could be a great tool to help your child learn the basics of budgeting.

Business model and Value proposition canvas

Lean canvas gather the meaning of smallest solution that delivers customers’s value. It is divided in two sides. Left side, is mainly focused on a product, where right side focuses on a market. Taking the main information from lean canvas I can resolve the value proposition canvas. I can present more specifically those two points in order to find the product market fit.

User scenarios

I take some assumptions to figure it out how is their user base, the way these users behaved and several possible use cases for the app.

Planned A Childrens Planned B Parents Planned C Parents

Often implies a single children buy, trying to buy some food or his cinema ticket.

In these moments maybe they don't have parental supervision. They can use the credit card with remote parental supervision or simply get the authorization by previous established filters.

A parallel scenario where parents recieve the pop-up notification.

The difference in advance is that parent should administrative, review and put some filter or choose the method to approve transactions.

In this scenario, the parent user is planning to make some give to his children, and he can suggest one of the offers that appear on our website

He can review what will be his payment method and if he prefers paid at the end of the month

Personas Millenial Mom
# Person kid
Generation USER Gen Z
Age group 3-23 y.o.
Size Roughly 25% of the population
Media Consumption The average Gen Zer received their first mobile phone at age 10.3 years. Many of them grew up playing with their parents’ mobile phones or tablets. They have grown up in a hyper-connected world, and the smartphone is their preferred method of communication. On average, they spend at least 3 hours a day on their mobile device.
Banking Habits: This generation has seen the struggle of Millennials and has adopted a more fiscally conservative approach. They want to avoid debt and appreciate accounts or services that aid in that endeavor. Debit cards top their priority list followed by mobile banking. Over 50% have not entered a bank branch in at least 3 months.
Shaping Events: Smartphones, social media, never knowing a country not at war, and seeing the financial struggles of their parents (Gen X). What’s next on their financial horizon: Learning about personal finance. They have a strong appetite for financial education and are opening savings accounts at younger ages than prior generations.

Generation USER Millennials (Gen Y)
Age group 24-38 y.o.
Size 95 Million
Media Consumption 95% still watch TV, but Netflix edges out traditional cable as the provider. Cord-cutting in favor of streaming services is the popular choice. This generation is extremely comfortable with mobile devices but 32% will still use a computer for purchases. They typically have multiple social media accounts.
Banking Habits: Millennials have less brand loyalty than previous generations. They prefer to shop product and features first and have little patience for inefficient or poor service. Because of this, Millennials place their trust in brands with superior product history such as Apple and Google. They seek digital tools to help manage their debt and see their banks as transactional as opposed to relational.
Shaping Events: The Great Recession, the technological explosion of the internet and social media, and 9/11 What’s next on their financial horizon: Millennials are entering the workforce with high amounts of student debt. This is delaying major purchases like weddings and homes. Because of this financial instability, Millennials prefer access over ownership which can be seen through their preference for on-demand services. They want partners that will help guide them to their big purchases.

UX Flow

With the proper planning, I was able to confidently move into creating wireframes for the app. I took the decision to focus more on the functionality and structure of the app, opting for low-fidelity wireframes with very little detail. Ultimately, I could add design elements in later, what was important for our users, was that the product (above all) was clear and simple.

UI Design

One major change in the app was to focus on personalization. Our aim was to improve user engagement by understanding more about a user’s personal preferences, allowing us to predict and tailor relevant info to each individual user.

I also needed to create a simpler, easier and more structured way to show the transactions to parents and children. Grouping their shop into categories and adding icons within the app, I created a simple and clear hierarchy user could learn and follow.

Creating authorization notifications was one of the most interesting features and experiences within the app. Ultimately, they’re designed to save users time and frustration. With a virtual feature, I removed the need for a parent at the moment of children's shopping.
