I can't find the spec anywhere. ETSI has a final spec for it, TS 102 622 (latest version is 10.2.0). I know the NFC forum is trying to come up with a competing standard: NCI. As far as I know they haven't released any spec for it yet. Cheers, Samuel. P.S.: All ETSI specs are freely available. -- Intel Open Source Technology Centre http://oss.intel.com/
