    Can a smartcard hold more than one certificate? Can the same card be used
    to log on to multiple accounts?

    Smart cards can hold as many certificates as there is storage on the card.
    The only problem is, the certificate that is used for smart card logon must
    be in first slot (first place) on the card. If it is not and e.g. only
    "Secure E-mail" certificate is in first slot, logon will fail. Other then
    this, you can have smart card logon certificate in first slot, and signing
    certificate in second and encrypting on third, authenticating certificate on
    fourth, etc...

    This is because the authentication process on logon windows can't display
    the list of certificates on smart card to chose with which you want to
    Kind of related is also the reason why you can't use certificate on smart
    card for EFS (private key used for EFS must be stored on hard drive)...

    I heard somewhere that this will change in next version of Windows... (I
    guess we will see -- I heard same thing about Windows 2003 some time before
    it was released).

    IsnĀ“t it so that the last added certificate will be considered to be "in the
    first slot"?

    I believe this would depend on CSP (Certificate Service Provider) -- but it
    appears that most of them work in the way you describe.

    On some smart cards (depends on CSP and management tools) you can even
    change the position of certificate...

    CSP = cryptographic service provider ...
