Smart Card Slot
Through PKCS11 module, DualShield supports Smart Card certificate. As you can see, you need to provide the library info and slot number.
Please ask your smart card vendor where the pkcs11 module is installed. in above example, the pkcs11 module of feitian epass2000 usb token is called ngp11v211.dll located in c:\windows\system32.
The slot number is quite tricky. you can try it from number 1, however you may be able to confirm it from Firefox Security Device Manager.
In this example, ePass Token is on the number 3 (number 1 is "FT SCR2000A 0" number 2 is "FT SCR2000A 1").
