|---|---|---|
| The code does not scan. | Contrast, quiet margin, size, payload density, or distortion is unsuitable. | Use dark foreground on a light background, preserve the margin, and test the final size. |
| The scan opens the wrong location. | The original input contains a typo or stale URL. | Inspect and test the exact decoded payload before distribution. |
Scan the final medium
Batas khusus alat ini: Low contrast, insufficient quiet margin, excessive payload, physical distortion, or very small printing can prevent a scan. Test the final printed or displayed code.
