Is there anything similar to a QR code that works offline?

Say I have a flyer that I want to discreetly distribute and there is no internet.

Is there something like a QR code that contains the data itself and not just a URL?

This way someone with no data plan could scan the icon/code with an app and the unrecognizable bits and bytes from the icon/code would show up on their screen as a .JPEG of a flyer or something.

    an offline version of the internet would be cool. and i think it’s very possible for like-minded people to create a quality subset.
    but to duplicate the whole trash dump of mostly spam… yeah that’s gonna require more storage capacity than most people have. [except maybe on the cloud]
    so, to conclude:
    i think it’s totally possible!
    it just needs to be highly selective for community curated quality content.
