4 alignment squares per QRcode doesnt work

I didnt think it would, but had to try .  LOL – I just created foursquare.

So the basis behind this experiment was if you could use the 30 percent error correction in a way that another system overrode the EC. So, I assume if I had nothing in that corner, it would have scanned, but adding random pixels that resembles an alignment square, shows that error correction does not apply, if the decoding algo does not apply if it is disoriented.

Logical, but I wanted to verify this made sense.

Experiment: 4 alignment squares does NOT work.
