User Pain Points
The existing payment system presented significant friction for users, requiring multiple steps to complete a transaction. This complex and time-consuming process often led to frustration, resulting in abandoned purchases and higher bounce rates. Our research involved analyzing user behavior and collecting feedback from a variety of sources, including surveys, user interviews, and data analytics from the payment flow.
Key findings revealed that:
Complex Checkout Process
Users were overwhelmed by the number of fields and steps required, leading to confusion and decision fatigue.
Inconsistent Payment Experience
The checkout process was inconsistent across each platforms, leading to a disjointed user experience.Time-Consuming
Many users abandoned their carts due to the time it took to complete the payment process, especially for returning customers who had to re-enter information.

Solution:
Fast Pay - A Simplified Mobile Payment System
To address these pain points, we introduced Fast Pay, a mobile digital payment solution designed to streamline the payment process. The goal was to make it simpler, faster, and more intuitive for users. The solution was informed by the following principles:
As-Is
The previous payment process involves multiple steps, resulting in a complicated and inconvenient user journey. Users are required to enter numerous details, leading to friction and frustration. This complexity often leads to increased bounce rates, with many users abandoning their transactions before completion.

To-Be
With Fast Pay, the payment process has been streamlined into just two simple steps. After users register their credit card information through the Fast Pay system, the only action required for payment is to swipe to pay. This significantly reduces friction, making the payment experience faster, more efficient, and user-friendly.

Logo
To visually express the speed and efficiency enabled by Fast Pay, an arrow graphic motif was introduced. The arrow originates from the letter ‘y’ and extends outward, symbolizing a swift and seamless user journey.
