The NFC Data Exchange Format (NDEF) is a data format to encapsulate and identify application data exchanged between NFC-enabled devices. One such device is the NFC Forum Type Tag. The NFC Type Tags are contactless cards based on currently available products capable of storing NDEF formatted data. NDEF and NFC Tags allow new kinds of touch-based applications such as Smart Poster, automatic wireless communication configuration, and electronic business card exchange. Such applications can be implemented using NFC-enabled Tag products already available in the market. This white paper describes NDEF, NFC Forum Type Tag Operations, NFC-enabled Tag products, and several related use cases.
