Case Study: a largest credit card company achieves stronger app security and lower churn with swIDch OTAC Device Authentication Token

Largest Credit Card Company - Customer Case Study

The largest credit card company in Korea faced a challenge with its B Pay app, where a complex authentication process mandated by financial authorities was causing user inconvenience, customer churn, and service slowdowns. They partnered with swIDch to implement its OTAC Device Authentication Token to streamline security and improve the user experience.

swIDch's solution used a dynamic, one-time authentication code generated directly on the user's device to unidirectionally verify it with the server, eliminating multiple steps at payment. This dramatically reduced unnecessary authentication, improved app speed, and enhanced security by blocking hacking attempts from other devices. swIDch helped significantly improve customer churn prevention and service availability for the app, which serves over 5 million monthly active users.
