They look plain and easy to make, but you can definitely fail to make them function if you don't follow the simple QR code do's and don't.
And generally, there are 11 reasons why your QR code is not functioning or working.
To generate a QR code that functions and easy to scan, you need to avoid these mistakes.
12 reasons why your QR code is not working
Before you start your QR code campaign journey, it's vital that you have idea how to properly create a QR code.
Good thing that the best QR code generator has got your back.
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 keep in mind when making your QR code is that- always make sure 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 come up with 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 the background and the foreground color of your QR code for the scanner to interpret the code quickly.
Do away from 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 colors are not good for scanning, so, it is best to use darker colors and white background.
You can add creativity with your QR code colors and experiment with it as long as 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 of high-quality and has a high-resolution in both screen and printed format, whether in a big or small size file.
Your QR code should have a sharp image to detect the code's borders that carry its content easily.
Regulate the amount of content in your QR code. So how do you do that? Have you ever noticed that some QR Codes are stretched and more pixelated than the others?
You need to know first what type of QR code you want to use: Static or Dynamic—static QR code stores data in the code's graphics.
The more data you put, the crowded the dots get shrinking the code in the corner that carries its information. When this happens, your QR code will be hard to read and detect.
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 that when displaying or printing small-sized codes, like QR codes in construction equipment, business cards, hardware chips, small product packaging, etc., it should be at least 2x2 cm (0.8x0.8 inch).
But of course, when you print them on billboards, say, for example, 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 just to be safe and always test them.
6. Strategic placement of your QR code
QR codes do not serve their purpose if they are unnoticed. Correctly position your QR codes where it can easily be seen by your target audience.
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, never forget to add a call-to-action and frame into your QR code.
7. You entered the wrong
Always check the data or URL you entered data. Sometimes there are little typos in your URL that break your QR code, or maybe it is 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.
It's always safer to scan and re-scan your QR code campaigns before deploying them live.
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 scans of the QR code, and they will expire.
However, QRTIGER provides unlimited scans of your QR code, and it is valid for a lifetime.
On the other hand, if you generate your QR code in dynamic, be sure always to 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 is 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-customize
Customization surely adds to your personal branding, but overdoing it makes the 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, adding unique edges, frames, image is enough to make them eye-catchy without looking scattered and too 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 in a billboard, be sure to to 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 why the QR code is not working is it might have also been disabled for some reason such as the campaign is over or turned off by the user.
So why QR codes are not working? Let' 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
- 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's 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.
