If the camera or QR Code scanning application on your smartphone is unable to detect your QR Code, then it could be because of the following reasons:
1. QR Code Size: The QR Code could be too small for your phone’s camera to identify its data modules. It’s crucial that you find the ideal size for your QR Code.
2. Wear &Tear: The QR Code might be physically damaged, making it unreadable for scanning devices
3. Scanning Distance: To scan a QR code successfully, ensure it fits within the scanning app's screen. This is possible by maintaining a reasonable distance between the code and your camera.
4. Uneven Surface: QR Codes scan best when they are on flat and even surfaces. Ideally, QR Codes should appear square-shaped both visually and to the scanning app. If you've printed a QR code on a curved surface, it might appear rectangular—making scanning tricky.
5. Custom Design: Adding custom design can also affect scannability. Generally, a large logo or poor contrast impacts scannability. To improve scannability, you can:
- Decrease the size of the logo.
- Increase the contrast between the color of your QR Code and the background. This means lightening the background and darkening the QR Code colors (eye and data).
6. Data Encoded: If you have created a QR Code with a large amount of data (high number of characters) then sometimes that QR Code might not be scannable via cameras with lower resolution. Generally, data encoded should be kept at a moderate level. The higher the amount of data, the lower should be the design customization
7. Outdated Technology: Scanning devices or software might be outdated and unable to read the QR Code format.
8. Software Issues: Scanning app or software might be experiencing bugs or compatibility issues, preventing it from scanning the QR Code
9. Interference: Environmental factors such as electromagnetic interference or radio frequency interference can disrupt the scanning process.
10. User Error: The person attempting to scan might be positioning the device incorrectly, scanning from a wrong angle, or using incompatible scanning settings.
