Summary<\/span><\/h2>\n
\n
\n
\n Worldline is a global leader in the cashless payments industry. For over 30 years, the company has been delivering secure solutions that support commerce across all channels, in-store, online, and on mobile devices, enabling the acceptance of card and alternative payment methods. To support further growth, Worldline needed to replace its existing payment platform with a more modern solution, while ensuring a safe migration and preserving the full range of functionalities used by key business customers. Sii delivered an integrated solution combining the legacy and new platforms, allowing Worldline to validate the target architecture, smoothly migrate customers, and reduce long-term maintenance costs through platform consolidation. \n <\/div>\n
