You have misunderstood the way OCF works.
You do not choose which card a CardService communicates. OCF does this.
You register your CardServiceFactory with OCF, and that factory must look
at the card to see if any of the CardServices (yours) the factory
supplies can work with the card. If they can, then it must return the
class of the CardService implementation to OCF.
Then your application can request the specific card service from BOTH
readers, and the one that succeeds is the one you use.
