Summary
Key results
A new version of the application capable of handling a significantly larger number of transactions
A higher level of system security
Rapidly increasing expectations for payment systems
In the cashless payments sector, transaction data must be processed quickly and predictably, in accordance with rigorous security standards, including full protection of cardholder data and access control.
In the face of a continuously growing number of transactions, Worldline required a newer and more efficient version of the application that would enable reading, collecting and processing card transaction data from multiple sources, including files and databases. At the same time, the solution had to comply with strict rules, such as tokenisation and anonymisation – methods used to secure sensitive cardholder data. It was also crucial to securely share the processed data with the client’s teams via internal network resources.
The project was entrusted to Sii Poland, a partner with experience in highly regulated environments and teams of specialists with documented project delivery success in the financial sector.
Dedicated team and a new system for transaction data processing
To address the complex requirements of the new version of the application, Sii Poland experts prepared a solution enabling stable and secure processing of card payment data.
The scope of work included:
- Formation of a dedicated Scrum team consisting of a Team Leader/Architect, developers, DevOps engineers and QA testers
- Development of a modern system capable of processing hundreds of thousands of records in real time
- Implementation of key business rules, including tokenisation and anonymisation of cardholder data
- Preparation of comprehensive reports and analytical tools supporting the work of teams
- Automation of deployment and testing processes (Continuous Integration/Continuous Delivery and monitoring)
- Provision of support and maintenance for existing systems, ensuring continuity of operations
The project was delivered using the Agile methodology, which enabled rapid delivery of subsequent functionalities, ongoing response to business requirements and full transparency of cooperation with the client.
A new version of the PAYONE application improving performance and security
The new application provided Worldline with a stable environment for processing large volumes of transaction data, replacing the existing solution with a flexible, containerised architecture prepared for cloud deployment. The company gained the ability to handle a significantly larger number of operations without increasing the load on the infrastructure, ensuring reliable system operation during periods of highest traffic.
By providing an open and well-documented integration interface, teams can more quickly connect new services and extend system functionality without the need to interfere with its core components. The modernisation also increased the level of data protection – the implemented mechanisms comply with PCI-DSS requirements, ensuring compliance with industry security regulations.
The introduction of structured delivery processes and DevOps practices resulted in shorter change delivery cycles and simpler long-term maintenance of the solution. The organisation gained greater operational predictability, more efficient data processing and a more flexible platform for the development of further services. After implementation, the system smoothly transitioned to the maintenance phase, enabling continued work without interruptions or risk to ongoing business operations.
