QR Code not working? Common causes and fixes

Why your QR code isn’t scanning

If your QR code isn’t working, the issue could be with the design or the material. Start by checking the size and contrast. A QR code must be large enough to be scanned, with at least 2 cm in width. If it’s too small, it might not be readable by most devices. Also, ensure there’s enough contrast between the code and the background. A light code on a dark background can cause scanning problems. If the code is printed on a glossy or reflective surface, it can create unwanted reflections that interfere with the scanner’s ability to read it. Always test your QR code before printing to avoid these issues.

Another common problem is distortion. If the code is stretched or compressed, it won’t scan correctly. Avoid printing on curved surfaces like bottles, as this can make the code unreadable. Also, make sure the code isn’t covered by logos or other graphics that take up too much space. If the code is static and contains too much data, it might not be readable. Use the Same-QR dashboard to create and test your dynamic QR code before printing.

Common causes of non-scanning QR codes

A QR code that doesn’t scan can be due to several factors. First, the code might be too small to be read properly. The minimum width should be at least 2 cm. Second, the code might lack a quiet zone, which is the empty space around the code that helps scanners recognize it. Third, the code might have low contrast, making it hard to scan. Fourth, the code might be printed on a reflective or glossy surface, causing glare that interferes with scanning.

These issues can be easily fixed by adjusting the design or material. Always test your QR code using a QR code scanner to ensure it works before printing. If you're using Same-QR, you can create and test dynamic QR codes without any issues. The platform allows you to generate up to 500 codes on the Agency plan, ensuring you have the tools to create reliable QR codes.

How to fix a non-scanning QR code

• Ensure the code is at least 2 cm wide for proper scanning.
• Add a quiet zone around the code for better recognition.
• Use high-contrast colors to improve readability.
• Avoid glossy or reflective materials that can cause glare.
