WHY DID WE START THE COOPERATION?

In recent years, foreign exchange operations moved into the internet. Because of that, our client decided to create his own, based on the current trends, solution. The aim was to prepare an application for:

selling and buying the currencies and four metals,
making the data analysis, using the graphs and percentages,
tracking the currency rates.

The first steps, connected with this project, were taken before our first contact. The client already had a ready-made server and a web application. However, the additional tests have shown, that people often use this kind of apps on their phones, f.e. during the trips. As a result, it was decided to create the mobile apps too, both for iOS and Android systems.

WHICH STRATEGY DID WE APPLY?

Due to the sudden idea of additional implementation, all the related actions had to be taken quickly because all the applications were to be published at the same time. We have created the solutions for Android and iOS from scratch.

In connection with the business profile, we focused on the highest standards of security. One of the most important part of this project, was to prepare the multi-factor authentication process. Its steps are:

entering a login and password,
robot verifiation,
validation of the password,
SMS message and an e-mail with an access code.

All the functionalities had to be consistent with the Financial Supervision Authority.
