Typically not, but could be. I'm not familiar with smart cards.

IMHO, this code is too complicated for testing. I recommend to remove
everything which is not related to the smart card sniffing. Remove all
the network stuff. Simply use DEV_DEBUG with stdio to output the data.

If you still get random data with minimalist code, then most likely the
problem is not caused by a bug in your application.
