From Tyson Key:
I've just finished writing a dissector for parts of the Sony FeliCa smartcard application layer protocol, as documented in JIS X 6319-4, (partially in) ISO 18092, and in various documents made publicly available at http://www.sony.net/Products/felica/business/tech-support/index.html. https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=6758 svn path=/trunk/; revision=40857
