MDN’s new design is in Beta! A sneak peek:

The readNDEF() method of the MozNFCTag interface retrieves the contents of the NDEF stored on the Tag, and returns an array of MozNDEFRecord objects.


Promise<sequence<MozNDEFRecord>> readNDEF();




A Promise object which will be resolved as an array of MozNDEFRecord.


DOMError with error type is InvalidStateError if the tag is already lost.


The NFC implementation in Gecko follows the NFC Forum specifications.
