Why Is My QR Code Not Scanning? Top 5 Causes & Quick Fixes
Troubleshoot low contrast, poor sizing, over-crowded data payloads, and blurry print issues.
1. Insufficient Color Contrast
Always maintain a dark code pattern on a light background. Inverting colors often prevents standard phone cameras from recognizing finder patterns.
2. Excessive Payload Length
Shorter URLs produce cleaner, less crowded pixel patterns that scan easily from further distances.
