Why Your QR Code Isn't Working: 12 Reasons

Sometimes, QR codes fail to scan or function properly for various reasons. Despite seeming simplicity and ease of creation, QR codes can prove ineffective if the basic rules of their creation and use are not followed. Have you wondered why your QR code isn't scanning? There are 12 main reasons why your QR code might not work or scan. By avoiding these mistakes, you can create a functional and easily scannable QR code.

Why Your QR Code Isn't Working: 12 Common Issues

Before planning successful marketing campaigns using QR codes for your business, it's important to understand how to correctly create QR codes using online generators. Is your QR code not scanning? Is scanning too slow? There are several reasons why this might be happening. Here are the main reasons why your QR code may not scan or function properly:

Inverted QR code colors are a major mistake.

The first rule when creating custom QR codes: avoid using inverted colors. QR code scanners are optimized to detect codes with darker elements against a lighter background, and otherwise, scanning may be difficult. Even the most creative design may turn out to be non-functional. To ensure ease of reading and decoding your QR code, it's best to use the correct color combination.

Insufficient QR code contrast.

If your QR code isn't scanning, avoid using similar tones of light or dark colors. For example, light colors like yellow or pastel shades may make scanning difficult. It's better to choose dark colors on a light background. A creative approach to QR code design is permissible, but you must ensure sufficient contrast for quick reading.

Blurred QR code.

For a QR code to be easily scannable, it must be clear. To create high-quality QR codes, it's recommended to use PNG or SVG formats, which ensure excellent print quality.

Pixelated QR code.

Avoid stretching and pixelation of QR codes. Depending on the type of QR code - static or dynamic - the amount of information affects the density and readability of the code. Dynamic QR codes, containing a short URL, allow avoiding information overload.

Incorrect QR code size.

The size of the QR code should match its placement location. For small objects, such as business cards or packaging, the minimum size is 2x2 cm. For larger surfaces, like billboards, the size should be correspondingly larger.

Inappropriate placement of the QR code.

QR codes must be well-visible and accessible for scanning. Proper placement of the code will ensure its visibility and ease of scanning.

Errors in QR code data.

Always verify the accuracy of the data or URL entered. Errors in the address or outdated links can render the QR code inoperative.

The expiration of the QR code.

For static QR codes, the number of scans and the validity period may be limited. Dynamic QR codes require maintaining an active subscription for operation.

QR code deleted or the link is inactive.

If the page the QR code links to is deleted or no longer exists, scanning will lead to an error.

Excessive customization of the QR code.

Too many design changes can make the QR code unreadable. Use moderate customization while maintaining its functionality.

Incorrect scanning distance.

Maintain the optimal distance for scanning, based on the size of the QR code and the distance to it.

The QR code was deactivated.

If a campaign with the QR code was concluded or deactivated, the code will cease to function. This may seem like a strange reason, but it can happen even with an electronic business card.
