The Knox TIMA Client Certificate Manager (CCM) allows a mobile device to simulate a smart card, and be used with NFC smart card readers. Its Keystore resides on an eSE (embedded Secure Element) on an NFC chip embedded inside a mobile device.
Android apps manage the Knox TIMA CCM using the API class: com.samsung.android.knox.keystore.ClientCertificateManager. Because this is a premium feature, end customers need a paid KLM (Knox) license to use it. Enterprises can get KLM licenses through Knox resellers. As a developer, you can get a free development Knox Platform for Enterprise (KPE) license through the SEAP portal to test the feature before deploying it. For the most up to date license information, see the about license page.
