Regarding the SIMtrace stuff: I haven't had too many problems with their
dissector - although it sometimes seems to assume the presence of status bytes
in places where they shouldn't be (usually in request APDUs), and it obviously
doesn't support ATRs at present.

The implementation of the PN532 protocol that I was working with wrapped
request packets in a 5 byte header (something like 0xFF 0x00 0x00 0x00
PayloadLength, if I remember correctly), and appended a status word (usually
0x90 0x00) to responses - so I needed to do some extra processing to remove
that encapsulation, prior to working with the payloads elsewhere.
