For companies that make "creative" QR codes, aren't they already giving up the 20% error correction?

- jfoutz 13y agoYes, but assuming errors are uniformly distributed, there's a chance read errors will actually correct problems. They'll occasionally flip the bit that was tampered with. So error correction gets worse (less effective), but maybe not as bad as you might believe.
- evilduck 13y agoIt depends on how creative they get. If they're just rounding the corners on the squares to make it look more fluid, then it's definitely not a full 20% being used. If they're plopping a logo into the center of it, then it depends on how large the logo is proportional to the code's size.
