About
We recently helped one of our clients which is a FinTech start-up company that was established in early 2019 in BGC, Taguig. They wanted to start their business in e-money, electronic payment, financial services, and all other related businesses. As per a report, the mobile payment industry in the Philippines is estimated to record a CAGR of 24.1% by the year 2025 with a total evaluation of US$ 19,816.4 million.
Similarly, the mobile wallet payment segment will increase at CAGR of 24.2% during the phase of 2018-2025 in value terms. Our client was aware of this fact and that’s why wanted to establish themselves as a leading FinTech firm in the Philippines. And to achieve that, they needed a mobile wallet solution with cutting-edge features that can fulfill all their requirements.
Challenges
To ensure REST API security
Ensuring security was one of the greatest challenges here as it was a digital wallet solution. We have to make sure that all the functionalities of the solution are 100% percent secure. For this securing REST API was a huge challenge since most of the solution provide REST API without any encryption.
Assure Android app security
It was very important to ensure the security of the Android app’s code as anyone can obtain the code by applying reverse engineering if it’s devoid of any kind of protection or security. Apart from that, the application also stores basic details like username, password, etc. So, it was important to secure these data too.
To achieve quick response time
We wanted to achieve quick response time for the application as we didn’t want any user to wait for a longer time and get frustrated.
Establish 100% server availability
We wanted to achieve 100% server availability so that the client can introduce new updates without facing any downtime. Similarly, we wanted to ensure that the application’s server doesn’t face downtime when there’s a sudden surge in the number of users in a short period.
Solution
