What Are QR Codes?

QR (Quick Response) codes are two-dimensional barcodes that store information. When scanned with a smartphone camera, they can:

• Open websites
• Display text
• Share contact information
• Connect to WiFi networks
• Trigger app actions

Why Use QR Codes?

Marketing Benefits

• Bridge print and digital media
• Track campaign performance
• Provide instant access to information
• Reduce friction in customer journey

Business Applications

• Contactless menus
• Product information
• Event check-ins
• Payment processing
• Authentication

QR Code Best Practices

1. Size Matters

Minimum sizes by use case:

| Application | Minimum Size |

|------------|--------------|

| Business cards | 2 x 2 cm |

| Flyers/Posters | 3 x 3 cm |

| Billboards | 30 x 30 cm |

| Product packaging | 1.5 x 1.5 cm |

Rule of thumb: QR code should be at least 1/10th of the scanning distance.

2. Ensure Contrast

• Dark code on light background works best
• Maintain at least 4:1 contrast ratio
• Avoid busy backgrounds
• Test in various lighting conditions

3. Include a Call to Action

Don't just show a QR code. Tell users:

• "Scan for menu"
• "Scan to download app"
• "Scan for exclusive discount"

4. Test Before Printing

• Scan with multiple devices
• Test different angles and distances
• Verify the destination works
• Check loading speed

5. Consider Error Correction

QR codes have built-in error correction:

• Level L: 7% recovery (smallest code)
• Level M: 15% recovery (standard)
• Level Q: 25% recovery
• Level H: 30% recovery (largest code)

Higher error correction = larger QR code but more reliable scanning.

Common Mistakes to Avoid

1. Making Codes Too Small

• Unreadable from intended distance
• Frustrates users
• Wastes marketing opportunity

2. Poor Placement

• Avoid curved surfaces
• Don't place where lighting is poor
• Ensure accessibility

3. Broken Links

• Test URLs before printing
• Use permanent URLs
• Consider URL shorteners with tracking

4. No Mobile Optimization

• Destination must be mobile-friendly
• Fast loading is essential
• Clear call to action on landing page
