Maybe I could add here too, what is known so far.
The pattern looks very much like a DataMatrix 2D barcode.
It has the tell-tale "frame" with a solid black line on bottom-left and a dotted on top-right wich is used to find the orientation of it.
The dots in the middle can be decoded.
Using this method,
The first 14x14 code reads: 32464142363331
The second 10x10 code reads: 45
Ofcourse, it is possible
MA made them look like this just to fool us, as a false trail.
But I think it is one step in the right direction.. would be too easy to just have it coded in binary or something, there is most probably a second layer of code...
Here is a site where you can create and decode DataMatrix 2D barcodes:
