By default, you can share a smart card between virtual machines or between the host system and one or more virtual machines. You might want to disable smart card sharing if you are using a PCMCIA smart card reader, deploying virtual machines for enterprise use and do not want to support drivers for various smart card readers, or the host system has drivers but the virtual machines do not.
The setting that controls smart card sharing is located in the Workstation Pro global configuration file.
