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.

      Are you saying the people who scan the QR coad will have to manually convert the text back to an image?

      Sounds cool, but perhaps not user friendly for others. Either way, I am on base64encoder.IO trying this out as we speak.

      Thanks.

        If you just want to pass on information, you can just write them out in text. Then whoever scans the code will simply see the text. I would say any QR reader you find will be able to do this. You don’t need to make it an image.

        Also, I don’t think a QR code is as discreet as you think. Anyone can scan it, even the people you don’t want to. I don’t know who you want to target and who you want to avoid, but to me it doesn’t seem like a QR code is good protection.
