Design tips that keep QR codes scannable
- Keep a quiet zone (white margin) around the code.
- High contrast: dark modules on light background.
- Test at the smallest size it will be printed.
- Avoid logos covering the three finder squares.
- Use PNG at 1024+ px for print, SVG for vector output.
Dynamic vs static
A static QR encodes the data directly — it never expires but can't be edited. Keep that in mind before printing thousands.
