1.3 What is the NDEF message format?

NFC tags use the NFC Data Exchange Format (NDEF) to store data within tags according to the NDEF standards. This allows any NFC-enabled devices to read the data from any NFC tag and interpret it. Most applications on NFC-enabled smartphones use NDEF when reading or writing data to NFC tags.
