TSM (Trusted Service Management)

In a multi-card application scenario based on multi-functional embedded secure element (eSE) (including cards, security chips, and NFC-enabled smartphones), services, technology, and security are required for eSE OTA and multi-application management. 

As a professional in providing secure digital transaction solutions, Watchdata offers a fast and secure Trusted Service Management (TSM) solution for downloading and managing multiple applications for eSEs. Through the Watchdata TSM platform, users can load applications in their physical cards (smart SIM cards, city cards, financial IC cards, access cards, etc.) anytime, anywhere, and on demand. Therefore, one card can be used for multiple purposes, saving card costs and rationally utilizing card space. It provides users with great convenience by supporting the download and management of applications in eSE online and placing different applications from various industries on the same physical carrier. 

As a system of credibility and openness, the Watchdata TSM provides comprehensive security protection, including management of security domains and applications, secure downloading of both COS and applet, and personalization through OTA.
