QR Code Guide

What is a QR Code?

QR codes (Quick Response) are 2D barcodes that can store much more data than traditional barcodes. They can encode text, URLs, contact info, WiFi credentials, and more.

Error Correction Levels

  • L (Low): 7% recovery — Smallest, best for clean environments
  • M (Medium): 15% recovery — Good balance
  • Q (Quartile): 25% recovery — Good for industrial use
  • H (High): 30% recovery — Best for damaged QR codes

Size vs Data

More data = larger QR code = harder to scan. Consider:

  • Use URL shorteners for long URLs
  • Higher error correction = larger QR code
  • Minimum version depends on data amount

QR Code Problems

Problem: QR Code Won't Scan

Causes:

  • Too much data (reduce or use URL shortener)
  • Low error correction + damage
  • Too small size
  • Low contrast (white/black not distinct enough)

Solutions:

  • Increase error correction to H
  • Increase QR size
  • Add quiet zone (white border)
  • Ensure good contrast

Problem: URL Too Long

Solution: Use a URL shortener like bit.ly or TinyURL to create shorter QR codes.

QR Code Tips

Best Practices

  • Size matters: Minimum 1cm (0.4 inch) for reliable scanning
  • Test with your phone: Always test with multiple devices
  • Leave quiet zone: White space around QR code
  • Use high contrast: Black on white works best

Creative QR Codes

Custom colors work but keep it simple:

  • Use dark colors on light backgrounds
  • Avoid gradients in QR patterns
  • Logo in center: use H-level error correction

Common Use Cases

  • URLs: https://example.com/page
  • WiFi: WIFI:T:WPA;S:NetworkName;P:password;;
  • vCard: Contact information
  • Email: mailto:[email protected]
