I doubt that people will know what to do with the "2D barcode" in 100 years. Someone who is willing to investigate will figure it out. But it is not something that will be convenient.
I for example wouldn't know what to do with a barcode even today.

I’m not.
Would you know what to do with a record? That's 150 year old technology. If not you know how to look up the information hopefully?
And, if you knew what to do with these things, would you be able to actually do it?
