PC/SC-Proxy allows for access to PC/SC daemons on remote machines. There are two use cases. It can be used with thin clients and a terminal server to make the session access readers connected to the thin client. In this case, the address of the remote PC/SC service is taken from the login information (utmp). The second use case is when applications running inside a virtual machine (e.g. VirtualBox) need access to card readers of the host machine without disturbing operations on the host itself.
