Part of the problem is that the GPL v3, section 0 requires that
"Appropriate Legal Notices" must be convenient from the perspective of
the user. The second problem is limited UI's can certainly be
interactive in the sense of interacting with the user (is there another
definition of "interactive" that I should know about?).
I suppose one option for the POS app might be: by default display the
copyright notice, wait for user input, and then go to the rest of the
application, but provide a way to start the application without the
notice (command-line switch that tells it to bypass this). This way
everyone will generally start the application without the notice, but it
takes more work than to actually see the notice, and newbies who don't
read the docs will almost certainly see the notice.
