If you are unable to scan the QR code, please check if any of the following factors apply:
For issues after scanning, please refer to "Result is not as expected."
1. Design Factors
Color & Contrast
Low contrast between the QR code and the background can prevent scanning.
Inverted colors (light code on a dark background) often cannot be read.
Tip: Ensure the background is light and the QR code is a dark, solid color.
Size
If the code is too small, cameras cannot focus on it. Please download the code in the recommended size.
See our "Download Instructions" for the recommended dimensions.
Resolution
If the QR code image is blurry, it will not scan correctly. In that case, please re-download it in SVG (vector format).
Quiet Zone (Margins) A "Quiet Zone" (empty space around the code) is essential for scanners to recognize the QR code. Ensure there is sufficient white space on all sides.
2. Printing Factors
Paper Material
Glossy paper or lamination can cause light reflections that interfere with scanning. Please print on matte-finished paper to avoid glare.
Surface Shape
QR codes wrapped around curved surfaces, such as bottles or poles, may become distorted and difficult to read.
3. Scanning Environment
Lighting Conditions
Scanning may fail in dark rooms or if your smartphone casts a shadow directly over the QR code.
Scanning Apps
Standard smartphone cameras are usually sufficient. However, if it isn't working, trying a different QR reader app may resolve the issue.
Note: Display formats may vary depending on the app used.
