What to put behind the code
Only the professional contact fields you want to share publicly.
Print for the place it will live
Starting size: 3 × 3 cm. This is a starting point, not a scanning guarantee. Dense contact payloads need a larger print than a short URL.
Use flat uncoated paper with a generous white margin. 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 reverse
- Contact sheet
- Reception directory card
Mistakes to avoid
- Adding a home address by accident
- Expecting existing contacts to update
- Using a tiny print for a large vCard
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.
