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.

An outdated, slow, and feature overloaded mobile application

Poor mobile app user experience and interface design

Limited number of Windows Phone devices amongst the company’s user base

A well-established reputation among enterprise-level and SME clients

High-demand product and service offering for a variety of industries

Experience in pioneering security solutions for cash counting, storage, and protection

Communication

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.

Business Process Mapping

01
CONSULTING

In a strategic meeting with the client, we charted and analyzed the existing processes. Together we determined both the weak . parts of the application to be removed and those performing well, which were to stay in the new version of the app.

02
DESIGN

With client’s preferences in mind, Computools team mapped the new application’s workflow. A streamlined and user-friendly application combined the best features of its predecessor with increased speed, security, and performance.

03
ENGINEERING

Business analysis of client’s requirements and solution modeling enabled Computools team to develop a detailed yet flexible development plan. Equipped with this roadmap, our developers and designers proceeded with the first stages of the project implementation.

Interactive Prototype

Having received client’s approval of the development roadmap, Computools team initialized interactive prototyping. Utilizing Proto.io, our UX designer developed a fully-interactive, high-fidelity prototype visualizing application’s performance without coding. Considering client’s requirements, our team designed a user-friendly interface with a streamlined flow.

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.

Specification

Using behaviour-driven development approach, Computools team created a detailed system requirements specification based on the user stories and the business process map.

Engineering

Computools team implemented the continuous integration and delivery system with automated testing to ensure full low-level protocols compatibility and the latest Android and Bluetooth versions support according to the client’s requirements. To complement the mobile app for cash handling, the developers implemented a server-side admin application for secure access keys generation and distribution among the users operating the banknote collection units. Regular code reviews by Team Lead boosted the development pace and promoted the timely stable release.
