Samsung KMS (SKMS) Agent is a client application for Android devices to support eSE-based mobile-NFC services. SKMS Agent manages the protocol with SKMS and forwards SKMS commands to eSE. SKMS Agent is used for interfaces between client applications & SKMS and SKMS & eSE. SKMS is considered as a HTTPS Server, while SKMS Agent is working as a HTTPS Client. A client application requests creating Card Content Management to Regional Trusted Service Manager first, and then requests a job execution to SKMS Server using SKMS Agent interface. No customer card data, personal financial information, or physical location information is exchanged
