Offline QR Code possibility? (lemmy.ml)

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.

Do all QR code phone apps do that, or just the one? Maybe it's a setting in the app that you can turn off. You'd think the app would be clever enough to recognise whether the message is a URL or not, and treat it appropriately.

QR codes can often be ticket numbers or lists of information. It's literally just text, but in a machine-readable form, instead of human-readable.
