    Please address if you can send an APDU to a real smart card in a reader similar to the API SCardTransmit().

    bdhc73a - I assume you are asking if there is an ability to send APDU to a smart card (real or virtual) using WinRT API from a Windows Store App. For Windows 8.1, this functionality is not available. Only Win32 applications can send APDUs to real or virtual smart cards.

    You are correct, I am waiting for smartcard access from a WinRT API.

    Is it a matter of policy that it is prevented, or a lack of resources?

    Hi Himanshu

    I'm in a conflict on whether you can define VSC and PIN (for example) as a real 2 factor authentication... A certificate which used for VSC and stored in the TPM can't really be pulled out (by the end user) like a real "Something you have" e.g. USB stick, so the "Something you have" is actually the device you're trying to authenticate to.

    Can you use the device you're authenticating to as an authentication factor ?

    You are right in that the certificate cannot be pulled out like a real "something you have". Hence, you cannot claim 2FA to the device itself. However, when authenticating to a network resource such as a website or a file share or authenticating for remote access for VPN, the device can be claimed as an authenticating factor because without the possession of the device, the user is not able to authenticate to the network resource. In those cases, the device is "something you have" and the PIN is "something you know".
