> That being said, I think it would be totally fair for a person to feel embarrassed about any personal information being displayed publicly on a monitor without their consent.

OK, but this is a pure fantasy, if not outright delusion. The way this display works is 1) it requires your consent, and 2) the information is only visible to a person standing in specific coordinates, i.e. you.

Please reread my comment. I laid out my assumptions in the second sentence:

> First of all, I should call out that I think our conversation is really about a hypothetical situation in which a display like this was operating in an airport for all passengers, whether they opted in or not.

You should try and engage me on the argument I'm making. Also, characterizing my comment as "pure fantasy" or "outright delusion" doesn't do much to make me more receptive to your viewpoint.

Sorry, I have zero interest in discussing some nonexistent hypothetical. Obviously, a technology that 1) was not opt-in, but universal, and 2) broadcast your information to not just you but everyone, would be problematic. You might as well add that this hypothetical system also broadcasts your credit card number while you're at it, and say that you would find this quite troubling indeed.
