Just out of curiosity, "think mirror". Would the QR code change at all if someone created a mirror image and then scanned it? Or would it just be the same link regardless? I'm not too keen on QR codes and how they work exactly.
If you create a mirror image of a QR code and then scan it, the QR code would indeed change in terms of its visual appearance, but the functionality would likely remain the same.
Here's why:
Symmetry: QR codes are designed with error correction capabilities. Most QR codes have a level of redundancy which allows them to be read even if part of the code is obscured or altered in some way.
Mirroring: When you mirror a QR code, you essentially flip it horizontally. This would change the position of the alignment patterns and data modules, but the data encoded within the QR code would still be retrievable by most QR code readers because of the error correction algorithms.
Error Correction: QR codes use error correction codes (ECC) which allow for up to about 30% of the code to be damaged or altered before it becomes unreadable. Mirroring falls within this tolerance for many QR codes, so the scanner would likely still decode the information correctly.
It's an interesting thought though. I wonder if you place a mirror over half the qr code whether it takes you somewhere.... or similar maybe divide it diagonally
