15 reasons why your QR code is not working
Before you start thinking 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 an online QR code generator.
Low scans? Low engagements? You're probably thinking, 'My QR code is not working'. There are various reasons why this happens.
Here are the reasons why your QR code won't scan or why your QR codes don't work:
1. Inverted QR code colors are a NO-NO
QR code scanners 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. It's best to use the right QR code color combination to ensure a scanner easily reads and decodes your QR code. This makes it easier for the scanner to access the stored information.
Solution: Edit your QR code design
With QR TIGER, you can redo your QR code design to fix design-related issues of your QR code with the Edit QR code design feature.
To do this, go to your dashboard and click the QR code you want to edit. Click Settings > Edit QR design > Save.
Take note that you can only do this if you're using a dynamic QR code. If it's static, we recommend you create a new one and follow the guidelines to color it correctly.
2. The QR code doesn’t have enough contrast
You can be creative with your custom QR code design by playing with the colored QR code scheme. However, don’t compromise its fast-reading capacity by not creating enough contrast.
An advanced custom QR code generator enables you to make your QR code more unique. You can even add a unique logo to make it look more professional and credible.
Just remember: the QR code color should be dark and set against a light-colored backdrop.
Solution: Adjust QR code contrast using QR TIGER's Edit QR design feature.
3. The QR code is blurry
Using photo editing apps may not suffice if the QR code is too blurry. To make a high-quality QR code image, we recommend using a dynamic QR code maker that lets you save your QR codes in high resolutions.
Solution: Download the QR image in PNG or SVG formats. Portable Network Graphics (PNG) are suitable for detailed images, while Scalable Vector Graphics (SVG) allows you to resize images without losing quality.
4. Pixelated QR code
A static QR code is a type of QR code generated by a dynamic QR code generator that stores data in the code’s pattern.
The more data you store, the more crowded the dots get, shrinking the code in the corner that carries its information. Your QR code will be hard to detect and read when this happens.
The codes need to be readable, and size is important for more points of view.
If you have more information to embed, it's best to use dynamic QR codes. A 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. This makes the dots less dense-looking, making scanning the QR code much easier.
Solution: Use dynamic QR codes for clearer and non-pixelated QR codes.
5. Consider the right size of the QR code
The size of the QR codes will depend on where you place them. It varies depending on your advertising environment and medium.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).
Of course, when you print them on billboards, say, 20 meters (65 feet) from where a passerby would be scanning, they would probably need to be about 2 meters (6.5 feet) across.
If you are unsure about the QR code size — print it in bigger sizes to be safe and always test it.
6. Strategic placement of your QR code
QR codes can’t serve their purpose if they go 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 ensure it 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, your URL has little typos 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.
Scan and re-scan your QR code campaigns before deploying them live is always safer.
8. Expired QR code
Static QR codes are generally free to create, but some QR code generators do not provide unlimited QR code scans, and they will expire.With QR TIGER, you can enjoy unlimited scans of your QR codes, valid for a lifetime.
On the other hand, if you generate your QR code in a dynamic, always renew your subscription before it expires.
QR code types like a dynamic QR code require a paid subscription as it is more advanced 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
If the page the QR code links to no longer exists, it directs you to a 404 error page, making the QR code invalid and must be deleted by the user.Broken links can cause a significant problem especially if you're using the QR codes on recurring marketing campaigns.
Solution: Generate a dynamic QR code to immediately replace the embedded link and fix the scanning problem.
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-catching 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 close enough to the QR code so that it can be scanned (it 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 is over or turned off by the user.For example, if you employ the Scarcity Principle in your QR code seasonal marketing campaign, say for Christmas, the creator can set it to deactivate automatically at a particular time or date.
Of course, if you scan one in February when the campaign has already ended, you'll be redirected to an alternate landing page with a message indicating the deactivation.
13. The scan limit of the QR code has been reached
Even if the subscription for a dynamic QR code has not yet ended, if the QR code has been scanned more than 500 times, which is its scan limit, it stops working.If you're eager to use and reuse your dynamic QR codes for a longer period of time, we recommend upgrading to a more advanced plan so that the scans are no longer limited.
14. Your smartphone does not support QR code scanning
Here's another factor you need to consider when you can't access the QR code: your smartphone does not have the capability to scan it.When QR codes work fine when others scan them and you can't, it might be because of the device you're using to scan them.
But this problem doesn't come without a solution. You can always download a highly rated and trusted third-party QR code scanner app instead.
This allows your smartphone to scan QR codes accurately even when it doesn't have a native or high-quality QR scanner.
15. The camera lens is dirty
If it's not about the QR code's appearance, activation period, the scanner, or the scanning method that is the problem, what else could be the root problem for QR codes not working?The answer is that your camera lens is dirty due to fingerprints, preventing it from recognizing the QR code in the first place.
Always clean your lens (use a gentle microfiber cloth to avoid scratching it) before scanning any QR code.
So why are QR codes not working? Let’s sum it up
- The QR code's colors are inverted.
- There is not enough color contrast.
- The QR code is blurry.
- It is pixelated.
- It is printed in the wrong size.
- The QR code has poor or wrong placement.
- It leads to a broken link.
- The subscription is expired.
- The QR code is invalid.
- Over-stylizing the QR code's look.
- The scanning device is positioned very close to the code.
- The QR code campaign has been disabled.
- Scans are limited.
- The smartphone does not support advanced QR code scanning.
- Dirty camera lens.
