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.
