About NDEF
NDEF is the NFC Forum’s record-based message format used by NFC tags, smart posters, and Android beam handovers. A message is a sequence of records; each record has a type, an optional ID, and a payload. Well-known type U carries URIs (with a 1-byte prefix code that expands to http://www., tel:, etc.); type T carries text with a language code; type Sp is a Smart Poster (a nested NDEF message).
