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
