Project
Description

Volumatic is a leader in intelligent physical cash handling solutions for Banking, Retail, and Leisure industries. Volumatic’s innovative solutions for counting, moving, and protecting banknotes enhance security, increase operational efficiency, and reduce shrinkage. Volumatic products across the globe secure over 4 billion dollars daily.

The previous incarnation of the CCi Assistant mobile application suffered a feature overload and lacked support, as it had been originally developed for Windows Phone OS. The app’s slow operation coupled with a limited number of Windows Phone devices among the user base encouraged Volumatic to redesign the application. Computools team was entrusted with the development of an Android mobile application to enable efficient management of cash collection, validation and counting through smartphones.

Outcome

Computools team has applied its deep knowledge to carry out a professional redesign of the client’s application, improve it and strengthen it. Thanks to these efforts and the coordinated work of specialists, the client was completely satisfied with the finished product.

Several key options we solved:

Made an app a cross-platform saving its best features.
Increased speed, security, and performance.
Added a user-friendly interface with a streamlined flow.

Digital Platform & Technology

Computools team carefully selected the best-suited set of technologies to fulfill the client’s goal of upgrading the outdated Windows Phone application and substituting it with a high-performance cross-platform solution.

Xamarin.Android

Android-specific Xamarin framework is perfectly suited for business logic applications with a streamlined design. This technology allows for maximum C# code repurposing when developing cross-platform applications, also accommodating the client’s requirements for further iOS development.

Xamarin.Forms

A portable class library enables native user interface development for Android and iOS devices using C# in Visual Studio. Cross-platform layouts and controls are mapped to native controls at runtime, making the designed interfaces fully native. Shared UI code is compatible with platform-specific APIs.

Passport JS

A modular authentication middleware for Node.js is easy to integrate into any Express-based cross-platform application. With 300+ authentication strategies, dynamic scope and permissions and lightweight code, Passport.js offers security and flexibility necessary for a business logic application for cash handling.

Communication Framework

We established a clear and efficient two-way communication, crucial for the successful digital transformation, through regular email reports and Skype calls. A structured documentation environment coupled with an access to Computools’ internal task management platform enabled the client to track the project’s progress and introduce necessary changes to the initial requirements.

Team Brainstorming

The project starts with a brainstorming session in a laptop-free zone with designers, developers, and project managers sharing ideas and feeding each other’s creative thinking.

Feedback Session

Every sprint is finalized by a feedback session with the client to factor in requirement changes and exchange ideas and opinions to reinforce innovative thinking and increase development efficiency.

Internal Communication Flow

Email and Skype were the Computools team primary internal communication channels for report sharing and addressing urgent issues. Regular audio and video conferences with the client enabled efficient communication throughout the development process. The client could follow the task assignment process and the project’s progress through Trello and Redmine project management platforms.
