Ligne 4 : − + − The NFC Data Exchange Format (NDEF) is a standardised data format that can be used to exchange information between any compatible NFC device and another NFC device or tag. The data format consists of '''NDEF Messages''' (messages NDEF) and '''NDEF Records''' (enregistrement NDEF). The standard is maintained by the NFC Forum and is freely available for consultation but requires accepting a license agreement to [http://www.nfc-forum.org/specs/spec_list/ download].+ − +

Le format d'échange de donnée NFC (NDEF) est un format de donnée normalisé qui peut être utilisé pour échanger des informations entre n'importe quel périphériques compatible NFC et un autre périphérique NFC (ou tag). Le format de donnée est composé de '''NDEF Messages''' (messages NDEF) et '''NDEF Records''' (enregistrement NDEF). Le standard est maintenu par le Forum NFC et librement consultable sur [http://www.nfc-forum.org/specs/spec_list/ download] mais nécessite que vous acceptiez un but requires accepting a license agreement to .
The NDEF format is used to store and exchange information like URIs, plain text, etc., using a commonly understood format. NFC tags like Mifare Classic cards can be configured as NDEF tags, and data written to them by one NFC device (NDEF Records) can be understood and accessed by any other NDEF compatible device. NDEF messages can also be used to exchange data between two active NFC devices in "peer-to-peer" mode. By adhering to the NDEF data exchange format during communication, devices that would otherwise have no meaningful knowledge of each other or common language are able to share data in an organised, mutually understandable manner.
