This project begins by identifying the issues with payment services that prioritize a simple checkout process. While these convenient checkout methods enhance the purchasing experience, they can also contribute to overspending. To address this challenge, we need services that encourage users to cultivate a sense of responsibility for their consumption habits.

The problem arises from identifying issues with payment services that prioritize a simple checkout process. While these convenient methods can lead to overspending, we need services that promote responsible consumption habits.

Track your spending with a budget calendar and reduce impulsive purchases through payment friction. If you exceed your weekly budget, a stronger “Spending Cutting Mode” will automatically activate, helping you stay on track with your finances.

By entering the amount of the product the you’re buying, it slows down the payment process and gives you a chance to gauge the actual cost.

If you choose another installment plan while you still have remaining payments, it displays the future installments you need to pay.

Each transaction is visually depicted with a circular graphic
which enhances awareness of this month's spending details 
and frequency of spending.

If you hold down the 'Pay Now' button for 5 seconds, it will vibrate, the gauge will fill up, and the payment will be completed.

What I've Learned

The Essence of Design: An Ethical Approach that Reflects the User's Voice

I explored what true user-centered design means. By focusing on ways to reduce overspending and avoid excessive unethical marketing, I gained a deeper understanding of my responsibilities as a designer. This project was recognized at the K Design Award and helped me establish a strong user-centered design philosophy.
