The QR code has become the essential bridge between the physical world and your digital business card. In 2026, 78% of smartphones regularly scan QR codes. Here's everything you need to know to create a professional and effective business card QR code.
Static QR code vs dynamic QR code
Static QR code: the URL is encoded directly. If you change your URL, the QR code is obsolete.
Dynamic QR code: points to a short URL that redirects. You can modify the destination anytime, and scans are tracked. Recommended for professional use.
Golden rules for an always-scannable QR code
- Minimum size: 2.5 cm × 2.5 cm when printed
- Quiet zone: leave at least 4 modules of white margin
- Multi-device test: scan from iPhone AND Android before printing
- Error correction: use level H (30%) if adding a logo
