With the S-POS Cube, the Sparkassen Financial Group expands its payment portfolio with a powerful solution for mobile transactions. This compact Android terminal combines robust hardware with the proven S-POS software. PAYONE – a joint venture between Worldline and the DSV Group – and S-Payment have launched a secure, convenient stand-alone solution that supports merchants wherever their customers want to pay: in-store, at markets, or on the go. Bluesource was responsible for key app components, user experience, and integrations within the mobile payment ecosystem – with a strong focus on security, payment acceptance, and usability.
A New Level of Freedom for Merchants
The goal of the project was to provide retailers with an independent mobile payment solution that operates without additional hardware while meeting the highest standards of security, user-friendliness, and robustness.
The S-POS Cube is based on Android technology, combining a compact design with strong processing power and offering merchants a wide range of payment options – from girocard, Mastercard, and Visa to Apple Pay, Google Pay, and Samsung Pay, as well as Alipay+ and Bluecode with “Scan to Pay on Mobile.” The device therefore represents a universal solution for anyone who wants to enable customers to make contactless payments, regardless of industry or sales environment.
An intuitive tipping dialogue, digital receipts instead of paper, a clear end-of-day report, and transparent transaction lists that are easy to browse and manage are among the Cube’s many features.
Intuitive Technology Meets Reliable Architecture
In developing the S-POS Cube, Bluesource relied on a holistic app concept that conceals the complexity of a payment terminal behind a clear, intuitive interface. The user guidance was designed so that even changing staff or temporary employees can use it safely right away, without the need for training.
The integration of payment methods and the processing of security-critical procedures were carried out in accordance with the highest standards of payment and platform regulations. Bluesource implemented robust protection mechanisms as well as intelligent error handling to ensure that the terminal continues to function reliably even in the event of network interruptions or location changes.
The device supports both Wi-Fi and SIM connections, ensuring full mobility. Whether on the sales floor, in the field, or at trade fairs – the Cube enables payment transactions wherever customers wish to pay.
User Experience that Inspires Trust
The great strength of the S-POS Cube lies in its combination of security and simplicity. Merchants process payments quickly and transparently, employees always have a clear overview of transactions, and customers enjoy a smooth payment experience – contactless, digital, and without waiting times.
Particular attention was paid to the user experience: clear structures, streamlined menus, and a visual language that makes every step of the payment process self-explanatory. The digital receipt function also helps protect the environment. As a result, the Cube becomes a tool that adapts to the rhythm of retail – not the other way around.
Development Partner with Payment DNA
The realization of the S-POS Cube is another example of the successful collaboration between S-Payment, PAYONE, CCV, and bluesource. With more than two decades of experience in mobile app development, banking, and payment technologies, bluesource combines technological excellence with a deep understanding of regulatory and operational requirements in the financial sector. The S-POS Cube solution was implemented in a remarkably short timeframe of just four months and is fully scalable, as its architecture allows for the easy integration of additional payment options.
Outlook: Flexibility That Continues to Grow
With the market launch of the S-POS Cube, the foundation has been laid – but development continues. New payment methods, additional features, and further integrations will be gradually added to meet the evolving needs of the retail sector. “The S-POS Cube is the result of a close connection between technology, design, and trust – and it demonstrates how simple payments can be today,” says Martin Sprengseis-Kogler, Managing Partner at bluesource.
