QR codes are powerful and easy-to-use tools, but sometimes you may run into issues that cause them to not scan or work properly. Here are 12 common reasons why your code might not work, plus how to fix each issue.
- Low image quality
What’s causing the problem: If the code is low-quality or blurry, it can be difficult for apps to read.
Solution: Make sure you’re using a high-quality QR code generator and keep the image at a high resolution.
- Complex design or inappropriate colors
What’s causing the problem: Overlapping colors or complex designs can make it difficult to read.
Solution: Use simple designs with good contrast between the background and the code. - The code is broken or damaged
What’s causing the problem: If the code has been damaged, it may not work.
Solution: Keep backup copies of the code, and print a new one if it’s damaged. - Using incorrect information
What’s causing the problem: If the code contains incorrect links or information, it won’t work as expected.
Solution: Verify that the information you entered is correct before generating the code. - Distance from the device used
Cause of the problem: When QR codes are too small or too far from the device used for scanning, they may not be read.
Solution: Make sure the code is the right size and easy to use, and is within the scanning range. - Poor lighting
Cause of the problem: Many readers require good lighting to scan effectively.
Solution: Try scanning the code in a well-lit area. If you are using your phone, point the light source at the code. - Insufficient QR Code app
Cause of the problem: Not all apps support all types of QR codes.
Solution: Make sure you are using a reliable and up-to-date app to scan codes. - Wrong orientation
Cause of the problem: The user may be far away or not focused while scanning the code.
Solution: Explain to the user how to properly orient the device to get a better result. - Unsupported format
Cause of the problem: Some devices may not support certain code formats.
Solution: Use common formats such as PNG or JPG when creating the code. - Inactive Links
Cause of the problem: If the code leads to an inactive or deleted link, it will not work.
Solution: Check and back up the links; you need to make sure they are working.
- Insufficient Scan Button
Cause of the problem: If the device used does not have the correct scan button or is not updated, this may cause the code to not be read.
Solution: Update the device or try another device to scan the code.
- Inappropriate Sip Location
Cause of the problem: If the code is placed in a hard-to-reach place, such as inside a booklet or hard-to-open material, the user may have difficulty scanning.
Solution: Make sure the code is placed in a place that is easy to access and scan without obstructions.
