> Obviously, there is data in the drawing.

I know this, and one can think of it as the numbers encoded in a plain old EAN-13 barcode. But as with these barcodes, the numbers by themselves don't usually have any meaning, they are just the key of a key-value pair. In this case the key-value database is in the Meshtag servers.

Like you said, the "raw numbers" can still be useful for small-scale labeling, but once you are at the point where you're just using the drawing to record a simple ID, it may be just easier to write the ID alphanumerically and have the computer OCR it or even just type it by hand (with a checksum digit, this can be more practical and effective than having to deal with camera scanners - "oh where is that app again/where did I leave my phone again...").

there could be much more data if you did a scribble, and it could translate to some specific data that could be useful (to stop by a third party number or code that doesn't mean anything by itself. is only useful to promote the cloud or to represent large amounts of data)
