Nexus Personal Desktop App can provision and manage virtual smart cards, which can be used for Windows-related use cases, such as authentication to external resources, protection of data by secure encryption, and integrity through reliable signing.

Personal Desktop App is based on Microsoft Virtual Smart Card (VSC) and Universal Windows Platform (UWP) technology and uses the Trusted Platform Module (TPM) chip, which is available in many computers, rather than requiring a separate physical smart card and reader. The solution uses native Microsoft mini-driver for communication with the VSC.

Personal Desktop App is integrated to Hermod for message distribution between Personal Desktop App and remote provisioning / verification entities such as Nexus PRIME and Nexus Hybrid Access Gateway
