the PDF reads:

One of the most important differences between pcsclite and  
Libchipcard3 is that
Libchipcard3 only accesses the readers when a Libchipcard3-client  
uses them
while pcsclite always grabs and locks all readers it can get – it  
never releases
unused readers. This makes it impossible for non-pcsclite  
applications to access
a reader while the PC/SC daemon is running.

My question: Do you really want to talk to a reader ? Can't you  
communicate with the reader via pcsc (SCardControl should do that)?  
Why not?

I think it is because of a different reason: libchipcard seems to be  
targeting German banking cards (and related secure readers) whereas
opensc is for card initalization as well as read only cards (like eID  
cards) Different areas (cards), same problems (readers).
