884478 - NFC MiFare Ultralight Tag Support

Status: RESOLVED WONTFIX

(Firefox OS Graveyard :: NFC, defect)

Description

[Garner Lee]

NFC (Near Field Communication) has a proprietary MiFare nfc tag created by NXP, commonly in use for transportation systems. This is not a standard NDEF formatted tag, but very important to support.

Support of this tag type may require re-writing the current NDEF centric API for consistency.

Tracking bug for MiFare tag support.

Garner, do we still need it some time in future?

To give context to this bug, a MiFare tag is not a must have, as the most common use case is using the phone with a transportion ticketing terminal. That case only needs the HCI Event Transaction (Bug 979767) to work, since the secure element cardlet does all the work.

It would be useful to define a user story to support it though. Supporting a tag is a "nice to have" but probably still needed for API completeness reasons.
