NFC Activities Specifications

Message coding format used by NFC reference

applications.Allows multiple NDEF messages.

Allows messages to be divided into chunks.


NFC Data exchangeFormat (NDEF)

Architecture



Defines how to construct records in NDEF messages.

Records may contain other records.

Each record has a type, indicating what it contains.

Record types are extensible they may be defined by NFCForum specifications (reference applications) or by otherbodies (using domain name).
