WhatsApp QR Code Not Working
If you are using the latest smartphones and still face the QR code scanning issue, it's time to troubleshoot the codes. Recent iOS updates enable iPhones to scan some bad quality QR codes, and certain Android smartphones running on Android 9 and above, like Pixel and Samsung S10+, can also handle such codes to some extent.
However, if your target audience includes users with old smartphones, scanning low-quality QR codes might not always be possible. To ensure better scannability and usage, it is advisable to fix poor-quality QR codes.
Why WhatsApp QR Code is Not Working?
There are many causes for the WhatsApp QR Code Not Working issue. Here are the reasons for the WhatsApp QR Code Not Working issue.
- Quality of the QR Code: High-quality images are crucial for proper QR Code scanning. Pixelated or blurry codes might still work on some devices, but it's best to optimize the quality by using high-resolution formats like SVG or PNG.
- Inverting colors is not recommended: Stick to the classic QR Code with a light color background and a dark color foreground. Avoid using a dark background and a light foreground as it may not scan correctly on all devices.
- Size of the QR Code: The QR Code's size matters for readability and functionality. The minimum size should be 2 x 2 inches or proportional to the surface it's placed on, like business cards or billboards.
- Be mindful of the contrast: Keep the foreground 40% darker than the background, even when using contrasting colors. Avoid using too many colors as it can affect the QR Code's scannability.
- Placement of the QR Code: Proper placement is crucial for the QR Code's success. It should be at eye level, large enough to be noticed, and not behind reflective surfaces.
- Avoid overcrowding the QR Code: Too much content can slow down scanning speed and cause issues. Keep the QR Code neat and crisp for faster and more reliable scanning.
- Expired QR Code: Using a poor-quality free QR code generator can result in codes that expire over time. The issue is compounded when users continue to scan the expired code, leading them to incorrect or outdated information. Some generators also have a scan limit, making the QR code unscannable after reaching the limit. To avoid this, it is advised to periodically test QR codes and use a reliable generator like Beaconstac.
- Broken Link: A QR code may lead to a broken link, indicating that the URL it points to no longer exists or has been mistyped. This not only creates a technical problem but also frustrates users. Common error messages like "404 not found," "500 internal server error," or "503 services unavailable" disrupt the user experience. To prevent this, it is essential to regularly test QR codes and ensure they direct users to functional and accurate websites. Dynamic QR codes can be helpful for updating URLs when needed.
- Over-customization of the QR Code: Customizing QR codes is beneficial for branding and campaign purposes, but excessive customization can lead to issues. Over-customization may make the QR code unrecognizable, such as using a busy background image, drastically changing the data pattern, or using similar colors that hinder readability. It is recommended not to add unnecessary elements that might hinder the QR code's functionality.
