It may not be easy to check if a smart card stack works or not. I will explain what you can do as a first step to check your smart card stack on Mac OS X.
The Apple pcsctest source code is available at http://opensource.apple.com/source/SmartCardServices/SmartCardServices-55111/src/PCSC/testpcsc.c
The good news is that this command line tool is installed by default. So every Mac OS X install should have it out of the box.

The program is then waiting for a card insertion.
If you have a card inserted and you do not get the ATR or an error then you have a problem.
If you insert a card and get the error "Card is unpowered" then you may have inserted the card the wrong way (or your card is dead).
System information
If your reader is connected but you can't see it withpcsctest then maybe the USB device is not seen by Mac OS X.You can use the System Information application from the /Applications/Utilities/ directory.

In the application you select the USB subsection in the Hardware section and can see all the USB devices known by the system.
Conclusion
These first steps are easy to execute on Mac OS X. If thepcsctest test succeeds then you can be confident that the smart card reader and the PC/SC layer are working correctly.If the
pcsctest test fails then you need to go to a level 2 smart card support on Mac OS X.
