QR Code Best Practices for Food Producers

Why QR Codes Matter for Food Traceability

QR codes have become the standard for food traceability, providing consumers with instant access to detailed product information. But not all QR codes are created equal.

QR Code Benefits for Food Producers

• Instant access to product information
• Enhanced consumer trust and transparency
• Compliance with EU traceability requirements
• Valuable customer engagement data

• Reduced customer service inquiries
• Marketing opportunities and brand building
• Faster recall notifications
• Competitive differentiation

QR Code Design Best Practices

1. Size and Placement

Optimal Sizes:

• Minimum: 20mm x 20mm (0.8" x 0.8")
• Recommended: 25mm x 25mm (1" x 1")
• For small packages: 15mm x 15mm minimum

Best Placement:

• Upper right or left corner
• Away from folds and seams
• On flat, non-curved surfaces
• Clear of other graphics

2. Error Correction Level

Choose the right error correction level based on your packaging conditions:

Low (L) - 7%

Best for clean, protected environments like retail shelves

Medium (M) - 15%

Recommended for most food packaging applications

High (H) - 30%

For challenging environments like cold storage or outdoor displays

Highest (Q) - 25%

For industrial environments or damaged packaging

3. Visual Design Guidelines

Colors:

• High contrast: Black on white or dark on light
• Avoid red and orange combinations
• Test readability with multiple devices
• Consider brand colors while maintaining contrast

Styling:

• Keep quiet zone: 4 modules minimum
• Avoid logos or text inside QR code
• Use rounded corners sparingly
• Test with multiple QR code scanners

Content and URL Best Practices

URL Structure
