Standard PIVKeys are shipped with a device certificate issued by the PIVKey Device Certificate Authority. This certificate includes the Global Unique ID (GUID) of the device.
If you want to use these certificates on a server or PC, you need to add the root certificates to the trusted root store. The url of the root certificates is embedded in the device certificate itself.
