brb patenting higher dimensional barcodes / tensor barcodes

Finally, we can use holograms for something mundane!

Pretty neat. You can encode 100 megabytes of data in a 4x4x4x4 cm tesseract, just need to apply an appropriate rotation around two of its axes and then you can extract the information as it intersects with 3d space.
That adds an additional temporal component to the scanning process which makes me hesitant.

However, the idea is ridiculous enough to greenlight.

Just go full panopticon with a thousand cameras, so that the looters don't need to put in all that selfie effort.
That’s Amazon Go.
They usually use 2D barcodes for weighed items at the deli.
