Data:

NDEF_TNF_EMPTY: Empty TNF indicates that there is no type or payload associated with this record.

NDEF_TNF_WELL_KNOWN: Well known TNF indicates that the TYPE field contains a value that follows the Record Type Definition (RTD) type name format defined in the NFC Forum RTD specification.

NDEF_TNF_MEDIA: Media TNF indicates that the TYPE field contains a value that follows the media-type BNF grammar defined in RFC 2046.

NDEF_TNF_ABSOLUTE_URI: Absolute URI TNF indicates that the Type field contains a value that follows the absolute-URI BNF construct defined by RFC 3986.

NDEF_TNF_EXTERNAL: External TNF indicates that the TYPE field contains a value that follows the type name format defined in specification NFC Record Type Definition (RTD) Specification for external type names.

NDEF_TNF_UNKNOWN: Unknown TNF indicate that the type of the payload is unknown.

NDEF_TNF_UNCHANGED: Unchanged TNF must be used in all middle record chunks and the terminating record chunk used in chunked payloads.; It must not be used in any other record.
