... forgot to add you need to enable the smartcard channel on the server side too. If you are using virt-manager then it is as simple as add-hardware->smartcard. If you are rolling your own command line then there are instructions in the doc file (link below), what you want is:
<qemu command line with -spice> -usb -device usb-ccid -device ccid-card-passthru,chardev=ccid
