If your QR code is not working, here are a few steps you can take to troubleshoot:
- Check the link or data: Ensure that the URL or information embedded in the QR code is correct. If it's a broken link, incorrect URL, or incomplete data, the code won't function.
- Scan with a different device/app: Some QR code readers may have trouble with certain formats. Try scanning the code using a different app or device to rule out compatibility issues.
- Test your internet connection: If your QR code links to a website, make sure you have a stable internet connection when scanning.
- Ensure clear contrast and resolution: QR codes need to be high-resolution and have clear contrast between the code and the background (e.g., black code on a white background). Blurry, distorted, or low-contrast codes may not be scannable.
- Check the size of the QR code The code should be large enough to scan easily. If it's too small, some devices may not be able to read it.
- Avoid overcomplicated designs: If your QR code is heavily customized (e.g., with logos or colors), make sure the code is still functional and not too distorted.
- Try regenerating the QR code: If none of the above works, try generating a new QR code and scanning it again.
Yes, once generated, the QR code is a static image that can be used as long as needed. If the linked content changes (for example, if the URL redirects to a different page), a new QR code would need to be generated.
