How to Use QR Codes on Business Cards and Marketing Materials
Add a QR code to your business card, flyer, or poster to let customers instantly access your website, contact info, or social media.
A business card with a QR code is not just modern — it dramatically increases engagement. Instead of hoping someone types your URL correctly, a QR code lets them scan and land directly on your page in one second.
What to Put in Your Business Card QR Code
- Website URL: Your business homepage or professional portfolio
- LinkedIn profile: Direct link to your professional profile
- WhatsApp Business: wa.me/yourphonenumber link for instant messaging
- Google Maps location: Your office or shop location
- vCard data: Encoded contact information that saves to the phone
- Instagram or YouTube channel: Social media links for content creators
