Here at Flomio we receive a lot of questions about how NFC tags work. What’s the difference between 14443A and 14443B? What’s a Type 2 tag? What about Felica? The NFC space can be a confusing space with multiple standards and tag types to worry about.
OverviewNFC Data Exchange Format, or NDEF, is the most widely supported format for writing and reading NFC tag data. It’s a lightweight, binary message format used to encapsulate arbitrary data like URL’s or MIME-TYPE. The format is composed of NDEF Messages which contain an array of NDEF Records each encapsulating a certain type of data.
