How to use a QR code: error examples + tips

Thanks to a QR code, you can carry out the most successful advertising campaigns. The QR technology itself can bring numerous advantages to the development of your project. At the same time, it is effective for both online and offline brand promotion.

However, what if you can't scan the QR code? Why QR code not working? How can you check it? And most importantly - how to prevent repeating mistakes? But first things first.

The reason for this decision is simple: the camera can’t recognize the QR code on the move, which means users simply won’t be able to scan it. Imagine an airplane in flight at an altitude of 7000 m. Does placing a QR code on it make common sense? Absolutely no.

QR code printing on cars, buses, and trolleybuses is also irrational. Of course, users can scan the code when the vehicle stops, but they certainly won’t be able to do that on the go. Moreover, the attempts to scan the code can lead to accidents, because the road user will focus on scanning and not on safety. Thus, your advertising campaign won’t bring the desired efficiency.

Try to remember the most unusual and unique haircut you've seen. Probably the most catchy mohawk doesn’t stand next to the QR code cut on the back of the head.

However, such a QR code will just elicit a smile but won’t bring any benefit. Try to choose more suitable places to put your codes if you want to achieve your desired ROI.

Hard-to-read and even unreadable QR codes on product packaging are not uncommon. Therefore, it’s important to consider the type of material on which your code will be printed. Creating a QR code for free is great, but you should make the scan test as well.

Now you know that it’s crucial to not only just print the QR code but to think over its design and rational placement. However, the question is left open: why is my QR code not working? Despite its simplicity in creation, mistakes do happen. The reason for this may be low contrast, poor clarity, large amount of encrypted information, small size, long distance, and more.
