This is Interesting. Who has heard of this one? Check out the video in particular. There is a few alternatives to QR codes.. QR codes have an error correction of up to 30%making them customizable up until that limit. However these look nothing like QR codes at all. QR codes are not the most visually pleasing looking compositions, so I can see these as being a good visual alternative. They would need to be clearly labeled as to what they are however, there are many people out there who don’t even know what a regular QR code is.
