What are common QR code problems?
Here are QR code scanning problems that hinder your QR codes from getting scanned. You should be aware of these when you create a QR code for your business or projects:
1. Blurry QR code
The clarity of the QR code after it was posted or printed matters a lot for scanning. A QR code is made up of different parts, and if any of these parts are not clear enough to scan, you will surely have scanning errors.
🌟How to fix this?
When downloading your QR codes, ensure they are in the correct formats. Usual formats include the following:
- PNG and JPEG - both are raster types and best fit for digital sharing and social media postings
- WebP - another raster type that’s best for fast-loading websites
- SVG and EPS - these are vector types and best for printing since they are scalable, which allows users to stretch the image without damaging the quality of the code
- PDF - also a vector type and best for print-ready documents
2. Improper size
Size could be a reason why your QR code is not working. When the QR code size does not match the distance where people are likely to scan, it will result in your QR code being too small or too large.
The QR code should be the right size in order for scanners to decode the information.
🌟How to fix this?
It’s important to calculate the correct QR code size based on the distance. Here’s the formula:
scanning distance ÷ 10 = minimum QR code width
3. Poor contrast of colors
Color contrast plays a crucial part in a successful scanning process. If the background and pattern colors are almost the same shade—meaning poor contrast—scanners will have a hard time identifying the scanning points.
🌟How to fix this?
Make sure that you choose different colors for the background and the patterns. Always choose a darker color for the pattern and a lighter one for the background.
4. Inverted colors
Say you’ve indeed chosen two different colors for the pattern and background as suggested above, now it’s important to remember not to swap the colors, as this can lead to problems with QR code scanning.
🌟How to fix this?
A personalized QR code should use a color combination that follows the rule of thumb: dark pattern + light background. Sample combinations:
- Black pattern + white background
- Red pattern + light pink background
- Dark blue pattern + light blue background
5. Broken link
No one wants to spend time scanning a QR code that points to broken content or a 404 error notice. People value their time and the benefit they get from scanning the code, so you must take this into consideration.
🌟How to fix this?
Make it a habit to check whether the embedded link or file in your QR code is working properly. Always perform a test scan and check whether it redirects to the correct information to avoid breaking the trust of those who wish to scan.
6. Damaged or obstructed QR code
The number of scans your QR code receives depends on how easily it can be scanned. If it’s badly positioned or torn, especially at the scanning points, it might cause problems with QR code scanning.
Similarly, if the QR code is placed under something that covers it, there’s no way scanners can read it.
🌟How to fix this?
Your QR codes must be in good condition. No tears or scratches, especially on the scanning points, and must not be covered with anything that could hinder the scanning process. Replace them immediately if you see signs of damage or remove foreign elements around them.
7. Over-customization
QR codes were previously popular in only the white-and-black color combination. But with QR code generators nowadays offering various customization tools, you may get overwhelmed and overdo the patterns, eyes, frames, CTA, and logos.
If your QR code is not scanning, it might be because these elements are not in sync, and customization might have done you more harm than good.
🌟How to fix this?
Old but gold, square-shaped QR codes are still the best. The corners help emphasize the eyes of the QR codes, making them easier for scanners to identify. While round QR codes seem appealing, you have to be extra cautious with them.
8. Poor lighting conditions
The lighting conditions are another reason a QR code is not working. Light is an important factor when detecting the scanning points. When your QR codes are positioned in a dark area, scanners can’t fully capture all elements, leading to scanning errors.
While smartphone scanners do have a “torch” or flashlight feature to improve lighting, you can’t always assume that people will use it.
🌟How to fix this?
Ensure that your QR code is in a well-lit place. It should have enough light so that scanners can detect all its elements.
9. Weak internet connection
If it’s a dynamic QR code, it will most likely require an internet connection. Sometimes a prompt appears telling you to connect to the network first, but at other times, there is no notification at all.
Only free QR codes can be scanned without an internet connection.
🌟How to fix this?
When scanning QR codes, always make sure you are connected to the internet or that your mobile data is on.
10. Scanning device issue
Old mobile device models usually have outdated scanning capabilities. They could scan basic solutions text or SMS, but would have issues scanning URLs or social media QR codes.
🌟How to fix this?
If you’re using an old smartphone without a built-in scanner, use Google Lens or download a QR code scanner with good user reviews to ensure your scans and device are safe.
11. Incorrect placement
Where is your QR code placed? Is it somewhere high up or ground low? Another factor to consider is the position of your QR code. If you intend to get many scans, it should naturally be in a public place, not in a secluded room.
If you want to gather feedback from a specific audience, placing it somewhere where that audience does not exist will do you no good.
🌟How to fix this?
Ensure that your QR code is scannable at eye level. Must not be too high or too low, and should be strategically placed, whether in public or private.

TL;DR: Summary of best QR code practices
- Properly download your QR code according to the platform where you intend to post it. SVG and EPS are best for scaling when you need to stretch for printing—it’s important to print at the correct size. PNG and JPG are best for online posting.
- It’s important to customize your code properly: colors should have contrast, a square frame is preferred, and you should add a compelling call to action.
- Placement is also significant in keeping your QR code scannable. Make sure to apply the phone-out rule for easier scanning, and position it in a well-lit area.
- Check your device for its scanning features; it might be outdated or not working properly, and you might need to download a third-party scanner instead.
- Embedded data should be active; if it’s a link, then it should still lead scanners to the right website.
QR codes are never wrong; you just have to use them right
The hesitation around using QR codes more likely stems from an undesirable experience. But it’s important to fully understand how a QR code works to reduce the causes of errors.
The causes of these QR code scanning problems are what make your QR codes ineffective. But if you learn to master the use of QR codes, they can be the most valuable tool you’ll ever have.

Frequently asked questions about QR code scanning problems
Can damaged QR codes still be read?
QR codes with minor damage may still be scannable, especially if the damage did not affect the important elements. QR codes with error correction will save you from trouble, so always create a QR code with a high error correction level.
How do I manually scan a QR code?
Most recent smartphones already have a built-in QR code scanner via their camera. You can try scanning, but if it doesn’t work, then you might have to turn on the QR code feature first.
