QR codes are everywhere — on business cards, restaurant menus, product packaging, event tickets, and marketing materials. Creating one should take seconds, not require downloading an app or signing up for a service.

What Can You Put in a QR Code?

  • Website URLs — link to your website, landing page, or social media profile
  • Plain text — share a message, instructions, or code snippet
  • WiFi credentials — let guests connect to your WiFi by scanning
  • Email addresses — open a pre-filled email compose window
  • Phone numbers — dial a number with one scan
  • vCards — share contact information directly
  • App store links — direct users to download your app

QR Code Best Practices

Size matters

For print materials, make your QR code at least 2 x 2 cm (about 0.8 x 0.8 inches). For billboards and posters, scale up proportionally — someone scanning from 10 feet away needs a bigger code.

Test before printing

Always scan your QR code with a real phone before printing. Test with multiple devices if possible — iOS and Android handle QR codes differently.

Use error correction

QR codes have built-in error correction. Higher error correction means the code still works even if partially damaged or obscured. Use "High" for printed materials that might get scratched or folded.

Add a call-to-action

Don't just slap a QR code on your material. Add text like "Scan to visit our website" or "Scan for WiFi password" so people know what they'll get.

Creative Uses for QR Codes

  • Business cards — link to your portfolio or LinkedIn profile
  • Product packaging — link to assembly instructions or recipes
  • Event management — paperless check-in at conferences and events
  • Restaurant menus — contactless digital menus
  • Real estate — link to property details on signs
  • Education — link to supplementary materials in textbooks
