What to put behind the code
Your public personal or company profile URL.
Print for the place it will live
Starting size: 2.5 × 2.5 cm. This is a starting point, not a scanning guarantee. A badge or card needs a close, steady scan.
Use a flat card area; hanging badges should not bend through the code. Keep the four-module quiet zone intact and use dark modules on a light background. Read the print-size guide.
Where to place it
- Business card
- Conference handout
- Portfolio cover
Mistakes to avoid
- Using a private settings URL
- Omitting your name
- Printing behind a reflective badge sleeve
Before committing to a print run
Print a proof on the final material. Scan it with more than one phone, from the normal viewing position. Check the opened destination while signed out and confirm it leads to the intended page or action. A readable fallback address or contact detail helps visitors who cannot scan.
