According to Android documentation:
Android (4.4 and above) supports emulating cards that are based on the NFC-Forum ISO-DEP specification (based on ISO/IEC 14443-4) and process Application Protocol Data Units (APDUs) as defined in the ISO/IEC 7816-4 specification
On the other hand, Falica cards are compliant with JIS: X6319-4 as per Felica's wiki entry.
So, presumably it is not possible to use an Android device for emulation of Felica cards. Is that accurate?
