12 reasons why your QR code is not working
Before you start to think about how to make successful QR code campaigns for your business, you must have an idea of how to properly create a QR code using a QR code generator online
Here are the reasons your QR code campaigns are not working:
1. Inverted QR code colors are a NO-NO
If there’s one thing you should remember when making your QR code, always ensure that your foreground color is darker than the background color.
This is the number one rule a QR code user should abide by.
QR code scanners easily and are set to detect QR codes with a darker contrast to the background.
Otherwise, it would be difficult to scan your QR code.
You may devise a great design, but it simply doesn’t work.
2. The QR code doesn’t have enough contrast
It is important to use colors that create enough contrast between your QR code’s background and foreground color for the scanner to interpret the code quickly.
Avoid blending or mixing similar light or dark colors; otherwise, it will take forever to scan it or never!
For example, light colors, such as yellow and pastel, are not good for scanning, so it is best to use darker colors and white backgrounds.
You can add creativity with your color QR code and experiment with it if you don’t compromise its fast-reading capacity by not creating enough contrast.
An advanced QR code generator enables you to customize your QR code more than just produce it in a monochromatic color.
Just remember: the QR code color should be dark and set against a light-colored backdrop.
3. The QR code is blurry
Blurry QR codes are hard to scan. So always make sure your QR code image is high-quality and has a high resolution in both screen and printed format, whether in a big or small file.
Your QR code should have a sharp image to detect the code’s borders that carry its content easily.
4. Pixelated QR code
Regulate your QR code’s content.
So how do you do that? Have you ever noticed that some QR Codes are stretched and more pixelated than others?
You need to know first what type of QR code you want to use: Static or Dynamic—static QR code, generated by a free QR code generator, stores data in the code’s graphics.
The more data you put, the more crowded the dots get shrinking the code in the corner that carries its information.
Your QR code will be hard to read and detect when this happens.
If you have more information to embed, switch to the Dynamic QR code. Dynamic QR code does not explicitly store the data right away in the code.
It contains a short URL stored in the QR code generator online that redirects the end-users to the destination information once scanned; thus, it avoids overcrowding your codes.
The codes need to be readable, and size is important for more points of view.
5. Consider the right size of the QR Code
The size of the QR code will depend on where you place them. It will vary in your advertising environment.
It is advisable to display or print small-sized codes, like QR codes in construction equipment, business cards, hardware chips, small product packaging, etc., at least 2×2 cm (0.8×0.8 inch).
But of course, when you print them on billboards, say, 20 meters (65 feet) from where a passer-by would be scanning, it would probably need to be about 2 meters (6.5 feet) across.
If you are doubtful about the size of your QR code, just print them in bigger sizes to be safe and always test them.
6. Strategic placement of your QR code
QR codes can’t serve their purpose if they are unnoticed.
Correctly position your QR codes so your target audience can easily see them.
Always place your QR code in the right position, location, or area, and make sure your QR Code is not overlooked!
Make it eye-level so your scanners’ eyes will go straight to the QR code.
Also, remember to add a call-to-action to your QR code frame.
7. You entered the wrong data
Always check the data or URL you entered data.
Sometimes there are little typos in your URL that break your QR code, or it may be linked to a website that no longer exists.
Check for broken links as well.
When generating your Squarespace QR code, WordPress QR code, and other website-redirection QR code campaigns, execute a test scan before deploying them.
Scanning and re-scan your QR code campaigns before deploying them live is always safer.
8. Expired QR code
If you generate your QR code in static, which is free to create, most QR code generators do not provide unlimited QR code scans, and they will expire.
However, QR TIGER provides unlimited scans of your QR code, valid for a lifetime.
On the other hand, if you generate your QR code in a dynamic, always renew your subscription before it expires.
Dynamic QR code requires a paid subscription as it is an advanced type of QR code with added features such as editing and tracking, which are not made available in static.
9. Invalid QR code or the URL where the QR code links to is deleted or no longer exists
The QR code is invalid and might be deleted by the user, or the page it links to no longer exists, and that redirects you to a 404 error page.
10. The QR code is over-customized
Customization surely adds to your branding but overdoing it results in an invalid QR code, undetectable by QR code readers.
Do not change the QR code data pattern extensively.
It will make them unrecognizable.
Making simple customizations with your QR code, like blending the right colors and adding unique edges, frames, and images is enough to make them eye-catchy without looking scattered and all over the place.
There is an axiom that goes, “less is more.”
11. Consider the distance from where you are scanning the QR code
If the QR code is in a closer range, maintain a slight distance to allow the scanner to detect the codes.
If you are scanning the QR code from afar, for example, on a billboard, get closer enough to the QR code where it can be scanned (must be within a reasonable distance range).
12. The QR code campaign has been disabled for some reason
Another reason the QR code is not working is it might have been disabled for some reason, such as the campaign being over or turned off by the user.
So why are QR codes not working? Let’s sum it up
- The QR codes are inverted in colors
- The codes do not have enough contrast
- It is pixelated
- The QR code is blurry
- Printed the wrong size
- Poor or wrong placement
- This leads to a broken link
- Is expired
- Invalid QR code
- The QR code campaign has been disabled
QR Code Pro-Tip
Always do a QR code test
The most effective way to do even before deploying your QR code is that always do a test.
Try scanning your QR codes in different operating systems to see if there are any problems scanning your QR and fix them before distributing or printing them.
And most importantly, always remember the 10 reasons why your QR code is not working.
