Why Business Card QR Codes Work
A business card has limited space — name, title, phone, email, and maybe a website. A QR code punches through that constraint by linking to whatever you want: your full portfolio, LinkedIn profile, Linktree page, demo reel, or digital business card.
What to Link From Your Business Card QR Code
Option 1: Personal Link Hub
Create a Linktree or personal landing page with all your important links. One QR code links to everything — portfolio, social profiles, contact form, calendar booking.
Option 2: vCard (Automatic Contact Import)
Encode a vCard so that scanning the QR code opens the “Add Contact” screen automatically. Format:
BEGIN:VCARD

END:VCARD
Option 3: LinkedIn Profile
Simply encode your LinkedIn profile URL. Many professionals prefer this for keeping things simple and professional.
Option 4: Portfolio or Work Samples
For designers, developers, photographers, or writers — link directly to your portfolio site.
Technical Requirements for Printing
Minimum size: Print at least 2cm × 2cm (about 0.8 inches square) for reliable scanning. On a standard business card, this typically means a QR code that takes up roughly 20–25% of one side.
Generate at 512px: Export your QR code at the highest resolution for crisp print quality. A 512×512px PNG at 300 DPI prints cleanly at up to 4.3cm × 4.3cm.
Error correction level H: Business cards get worn, bent, and sometimes wet. Level H allows 30% of the code to be damaged and still scan successfully.
Quiet zone: Leave at least 4 modules (the small squares) of white space around the entire QR code. Don’t let other design elements crowd it.
Testing Before You Print
Print one test copy and scan it with:
- iPhone camera (native iOS QR scanner)
- Android camera (Google Lens)
- A dedicated QR code scanning app
If all three read it correctly, you’re ready to print the full batch.
Design Tips
- Dark on white: Standard black QR on white background is the most reliable
- Colored QR codes: You can use brand colors but keep the contrast ratio high
- Logo overlay: Some QR generators allow a logo in the center — if you do this, use error correction H to compensate
- Label it: Add small text like “Scan to connect” or “Portfolio →” near the QR code so people know what they’ll get
