Best Practices

Data Content

1. Keep URLs Short - Shorter URLs create simpler QR codes
2. Test Scannability - Verify code scans on various devices
3. Use HTTPS - Secure URLs are more trustworthy
4. Avoid Special Characters - Some characters may cause issues
5. Consider Data Size - More data = more complex QR code

Display Guidelines

1. Size Matters - Minimum 2cm x 2cm for print
2. High Contrast - Black on white works best
3. Add Context - Include instructions "Scan here"
4. Error Correction - QR codes have built-in redundancy
5. Test Before Distribution - Always test generated codes

Security Considerations

1. Validate URLs - Ensure URLs point to your domain
2. Use Unique Codes - Don't reuse codes for different users
3. Expire as Needed - Implement expiration for sensitive data
4. Track Usage - Monitor which QR codes are scanned
5. Avoid Sensitive Data - Don't encode passwords or secrets

Performance Tips

1. Cache URLs - Store generated QR code URLs
2. Batch Generation - Generate multiple codes together
3. Reuse When Possible - Same data = same QR code
4. Optimize Size - Shorter data = faster generation
5. CDN Delivery - Images served via CDN for speed

What You Get Back

After generating a QR code:

• Image URL: Direct link to the QR code image
  • Hosted and accessible
  • PNG format
  • High quality, scannable
  • Permanent (doesn't expire)
  • Ready to display, email, or download

Example URL:

https://storage.yourservice.com/qrcodes/abc123def456.png

Tips for Success

1. Test First - Generate test QR codes before production use
2. Multiple Devices - Test scanning on different phones
3. Lighting Conditions - Verify codes work in various lighting
4. Size Appropriately - Larger for distance scanning
5. Provide Fallback - Always include the actual URL as text
6. Track Performance - Monitor scan rates and usage
7. Update as Needed - Generate fresh codes when data changes
8. Document Usage - Note what each QR code is for

❌ Don't: Reuse dynamic codes for different users ✅ Do: Generate unique codes per user/order/event

❌ Don't: Assume everyone knows what QR codes are ✅ Do: Provide clear scanning instructions
