Use cases & print ideas

Matching pages that explain where this QR type works best before you open the generator.
Business Card QR Code Ideas for Contact Sharing
Use a business card QR when the next step should be saving a contact, not typing details or visiting a plain web page.
Redirect QR Code Use Cases
Use Redirect QR for a controlled destination path; only hosted dynamic QR lets the printed asset stay fixed while the destination changes after launch.

Business cards are a tough environment: small size, glossy prints, and busy designs. Here are the fastest fixes.

Fix the 3 most common causes#

  • Too small: use 20–25mm (or larger if you use a long vCard).
  • No quiet zone: don't crop the QR in design tools.
  • Blur / low contrast: avoid low-contrast colors and glossy reflections.
