Is IATA involved in specing the new eTag? Because I'm fairly sure that whatever IATA says at present about baggage tags, it says absolutely nothing about allowing the DCS to interface with any sort of electronic ink tags (they can't be printed in the same manner as paper tags currently are, so every airline and every airport would have to invest in some sort of technology that would allow the baggage tag information that at present is delivered only to their own baggage label printer to also be deliverable to such a tag - this ability simply does not exist at present).

My point is that airlines outside of Skyteam may dislike this initiative and not allow their DCS to interface with these tags (they may decide to use their own alliance tags, if the scenario that competing systems arise, or if they merely dislike the way Skyteam attempts to roll out an industry-wide system). Of course, some might find it a great idea and gladly introduce the system, but I can't imagine every airline automatically rowing behind what appears to be a Skyteam initiative, especially when there is no problem with the current paper-based system!
