Hi, there is a project for Gen2 RFID chips, they have a reader implementation for the USRP1 and a monitoring tool to eavesdrop on reader-tag communication for the USRP2: https://www.cgran.org/wiki/Gen2
There are also papers on the design posted there. They had to tinker with the USB driver as well because of timing issues with the reader. I think Gen2 is only ~868MHz, I don't know if the code can be adapted to 13.56MHz stuff. And for a (duplex) reader you will need a URSP1 there, because two 900-daughterboards are required. It may be possible out of the box to build a reader for 13.56MHz with the USRP2, as you have two "half"-daughterboards. For the protocol implementation, you can take a look at http://www.libnfc.org it seems that they have some Gen1 support and you only have to implement the physical layer in gnuradio. We are currently thinking to start a RFID project as well, so I'm interested what you find out.
