Normally that is locked out from public access on every commercial deployment I have seen so far. And I don't seen the need to restrict it to mobile devices. > > - The digital signage system is RECOMMENDED to be capable of uploading of > > emergency information from administrative mobile devices, if the connection > > with content management system is lost. > Ditto for the mobile comment. It's also very likely that the administration console is very likely to be a PC of some sort - just to be factually correct, I don't think the word "mobile" is needed here. > > - The digital signage system is RECOMMENDED to be capable of providing > > detailed emergency information to user's devices, and RECOMMENDED to > > display a method how to get the information. > "Providing" is pretty vague. Are you implying that the terminal should provide a method to digitally copy the information over to a client? That's at least one would guess since there is a "user device" in the context - in which case the wording of the actions should be made more specific. If so, I think there should be at least one recommended transport method here. (I don't have any good ideas, NFC is probably one option but the amount of data you can transmit over is quite limited, and realistically I don't see people lining up to touch their phones on a sign during a emergency situation - but that could be just me assuming people don't follow the rules when there is a disaster.) While we aren't making a normative document here (although I seriously wish we could) making the transport method completely open ended just makes life complicated for implementors. Sangwhan
