Thomas,

Thanks for responding...

The PC/SC specifications define a kind of generic API that kind of
virtualizes a real smartcard. In the original (beta?) SmartcardSDK
awhile ago, there use to be a sample or "reference implementation" of a
PC/SC service provider (SP), called SCARDCOM. The idea was that PC/SC
SPs were suppose to 'wrap' the physical interface of the actual
smartcard.

When you installed the Smartcard SDK, you got 3 exex (Winbase.exe,
scbase.exe, and one more that I can't remember), and you ended up with a
directory tree that included the SCARDCOM sample, plus several others.

What I'm looking for specifically is where/how to get the SCARDCOM
sample, or, if it's been superceded by some other sample.

It sounds like what you're doing is writing smartcard "client"
applications. From your post, I gather that you're using the Scard...
API calls.

An SP would wrap the Scard... calls, and expose the PC/SC-specified API
instead, i.e., kind of a higher-level API that was COM-based. By using
SPs, and the MS Resource Manager, you could almost write smartcard
applications that were somewhat card-independent (since the apps would
be talking to the PC/SC API, which was hiding the real card details).

I think that people who write SPs for specific cards (either working for
smartcard companies or who want to virtualize their apps interface to
real smartcards) would be the ones who would be using the SCARDCOM
sample...
