Brief

Our client is a company that provides its customers with financing and a deferred payment system. The product we created for them was a mobile application that allows people to use a virtual card, delivered by a third-party company. A limit must be assigned to the card, which the user will have to repay later. The card allows payment by pairing it with a card set up on the phone but also has a generated number that can be used for online payments. The work to be done by Applover was the mobile part of the application created in Flutter.

The challenge

Due to the fact that the project required a lot of confidential financial data and transactions, we had to put security in the first place. The project’s backend part had to be provided by the client, which required integration on our side. Moreover, handling sensitive data in this project was quite a big challenge for us. 

Another one was the integration with the external provider responsible for the service of cards. We had to overcome some communication troubles and missing information during the project.

Development Time

Technological solution

Due to the specific circumstances of our client’s industry, we had to pay special attention to security conditions while developing this project. The display of sensitive data will require the user to authenticate using biometrics or a security code. By sensitive data, we mean card numbers and CVV2 numbers. These data can only be displayed for a period of 120 seconds, after which they have been hidden again. For security reasons, taking screenshots throughout the application is impossible. What’s more, a security code will be used to approve many operations in the app, such as changing the PIN of the card, displaying sensitive data, entering the app, and approving payments, among others. An alternative means of authorization to the security code for taking certain actions, such as entering the app, are biometrics. Depending on the phone and system, there are available two types of biometrics: fingerprint or Face ID.

Despite some challenges that we had to face in this project due to specific circumstances and dealing with the security aspects, the whole cooperation with our client was satisfying and fruitful.
