I've just finished writing a dissector for the NXP-proprietary MiFare Protocol,
as used alongside ISO 14443-A by a popular range of contactless (not-so-smart)
cards, and various emulations, variants and clones thereof.

It currently supports all of the commands listed in
http://www.nxp.com/documents/data_sheet/MF1S703x.pdf that also happen to be
supported by LibNFC (http://code.google.com/p/libnfc/) - modulo the "NAK" and
CRC bytes, since I haven't found examples of their usage in my USB traces, and
I didn't want to hand-craft (probably incorrect) examples for testing.

I've tested it against a quickly-modified version of the dissector in Bug 6155,
and also against a sample file created using text2pcap using data extracted
from parts of USB traces, and hand-crafted data where I was unable to generate
any using my small collection of RFID tokens and reader.

The source code for that modified dissector is published at
https://bitbucket.org/vmlemon/smartcardtools/src/tip/USBSmartCardDissector/, if
necessary; and I'll attach the text2pcap sample shortly.
