There is an additional dedicated smartcard channel that you can use. It is meant for using a smartcard in the guest while keeping the ability to use the smartcard in the client. With usb remoting you do not have access to the smartcard device on the client. Usage is like:

remote-viewer --spice-smartcard <other options>

It works well with linux guests, but we don't have recent reports on windows guests working, although it was tested more then a year ago.

I'll be happy to have new reports..
