.NET cards version v3 and later
The .NET card with the assembly version v18.104.22.168 supports the SPE feature as long as the PIN type is configured as "External PIN". The PIN type is one of the options that can be set in the PIN property.
You cannot use a PIN pad reader to enter the PIN for a smart card logon (even if the External PIN property has been set in the card). You can use a PIN pad reader to enter the PIN for any other authentication, such as an SSL connection, digital signature, mail encryption and so on.
For testing purpose, the Minidriver Manager tool can be used to change the PIN type (right click on the User PIN, Change PIN properties and PIN Type )
