New challenges of credit card core system

While major banks are seizing new heights for the development of digital credit cards, the technological changes surrounding digital credit card initiatives are becoming more imminent. Hence, the refresh of the credit card core system, the "heart" of the overall credit card business is the essence in providing non- stop services to cardholders.

The prevalence of digital credit cards poses new challenges to the banks’ credit card core system at different levels:

-    Architectural level

An enterprise-level microservices and distributed technology architecture can greatly improve the reusability of functional modules and increase the speed of docking. Field segmentation is performed on the basis of maintaining stability and efficiency with the support of loose coupling between fields, easy expansion within the field as well as enabling centralized parameter management and operations.

-   Business level

A service-oriented system that provides support based on business areas rather than software system structure that focuses on users with the improved customer insights and providing services based on user journey. Product pricing is refined to the scenario level, marketing activities are differentiated according to different dimensions and services are refined through smart risk management and control capabilities. The componentized and configurable business strategies, product factories can quickly release new products. Large operating platforms support full-platform operations and flexible deployment of business resources enable services available 24x7.

-   Data level

Through data-driven business processes, real-time data is used to support decision-making at all levels and achieve real-time decision-making. Customer segmentation based on digital insights promote and increase the scale of interest-bearing assets while event-driven streaming services provide multiple customer services via a single touch. Operation and maintenance monitoring and operation data actively reveal operation hotspots, allowing administrators at all levels to understand the front-line situation in real time, allowing decision making and resources allocation efficiently.

The ability of the credit card business to achieve smooth operation depends greatly on the “vitality and health” of the credit card core.
