Hello,
if you would use shared instead of exclusive, other PC/SC applications may
access the card in parallel with OCF applications. As smart cards usually
support only one session, other PC/SC applications could disturb the OCF
applications, e.g. by selectoing other directories, invalidating security
contexts, etc.
Best regards,
Thomas

I'd like to rephrase this with the question that I actually want answered.
What would happen if I changed the PCSC Card terminal to use SHARED rather
than EXCLUSIVE?
