Complete QR Code Troubleshooting: Camera Lock & Scanning Fixes

If your QR code is not scanning properly, use this diagnostic checklist to find and fix the issue immediately.

Checklist for Instant Fixes

• Inverted Colors? Always use dark modules on a light background. Light codes on dark surfaces fail on 40% of older smartphone models.
• Payload Too Long? Shorter URLs generate larger, cleaner modules with fewer rows, making scanning 3x faster.
• Glossy Surface Reflections? Laminated menus or shiny packaging can cause light glare. Position lights away from direct reflection angles.
• Check Quiet Zone Margin: Ensure at least 4 modules of empty space on all four sides.
