I've written a dissector for the variant of the NXP PN532 chipset protocol
(documented at http://www.nxp.com/documents/user_manual/141520.pdf) used by the
ACS ACR122U card reader that currently identifies all of the packets mentioned
in that document.

Support for dissection of the following packet types is mostly implemented:

 * Get Firmware Version (command/response)
 * Initiator: List Passive Targets (command/response) - works with my handful
of ISO 14443-A/B tags (a MiFare Classic-based student ID card, a DESFire
EV1-based public transport card, some MiFare UltraLight tokens, and some
14443-B-based sample cards from Maxim Integrated Products that I have), and
FeliCa Lite tokens

I'm still working on implementing support for other packet types - although my
reader doesn't utilise all of them; and some reverse-engineering and guesswork
is necessary at times.
