Overview of the Technology Platform Provided
For many companies today, digitalizing back-office operations and strengthening governance over expense management—including the prevention of unauthorized use—have become pressing priorities.
For this latest enhancement to “Sumitomo Mitsui Card Purchase Plus,” Infcurion drew on its proven expertise in building secure, PCI DSS-compliant (*3) systems, together with its UI/UX know-how in enhancing ease of use for corporate card members. By implementing the supporting digital infrastructure that seamlessly handles everything from issuing and modifying child card numbers, to card-number inquiries, expanded notifications such as email alerts, and transaction-statement management, Infcurion contributed to the swift rollout of these new, highly secure features.
*3 PCI DSS (Payment Card Industry Data Security Standard) is an international data security standard for the payment card industry.

Infcurion will continue to build on what it has learned through this initiative going forward.
