I'm currently in the process of trying to write an ifd handler to be able to use librfid in openct (and therefore in opensc and pc/sc) to be run with the librfid that uses a patched openct ccid ifd handler that offers the ESCAPE protocol. (E.g. I'm talking about a cardman 5121 here.)

The current way of having an openct ifd handler calling a library that calls another openct ifd handler seems to be ugly. For the future it would be nice to have the contact-less support in the same ifd as the contact-based part, e.g. as an additional slot (or even several slots, because I've been told that 4 cards should be possible). This would also nicely solve hotplug. Of course the most easy way would be to subclass the ccid handler, if there was something like subclassing in C.
I don't have a Cardman 5121 so what I write may not apply to the Cardman 5121. The SCM Micro SCR 331-DI and the SCM Micro SDI 010 are contact + contactless readers. They are seen a one reader with two slots under pcsc-lite with my CCID driver [1]. The contactless slot uses normal APDU and the reader firmware manages T=CL (or whatever it is) itself. The OmniKey CardMan 5125 is also a dual interface reader and is reported as "should work" with my CCID driver. But I didn't tested it myself and do not remember if the contactless interface is also available from my CCID driver. The second slot (for contactless cards) can only manage one card at a time even if the reader could manage more cards simultaniously. But I don't have any documentation for the contactless commands and used reverse engineering of the windows driver to guess how I could use the contactless interface. It would be nice if librfid could be used from a PC/SC application. But maybe the PC/SC API is not rich enough to (efficiently) play with contcatless cards.
