Very interesting video, I had no idea the level of redundancy built into QR codes. Thanks!

RIGHT?!! Same here. I didn't know there was SO MUCH of thought put behind QR codes. I always assumed they were just bits visually represented in 2D with the three black squares being there for alignment purposes. Turns out it is a lot more complicated than that hehe

Thanks!

Same! And now I know why my phone is able to scan a QR code, even when it's only partially in the frame/border that comes up.
