a prime example of this, as they offer convenience and quick access to information but can also be a source of frustration when they don’t scan properly. </strong></p><p><strong>Blurred images, </strong><strong>broken links</strong><strong>, and the wrong </strong><strong>background color</strong><strong> are just a few of the many issues that can arise when </strong><a

These issues can be especially frustrating if you’re in a hurry or relying on the code for important information.</strong><strong> </strong></p><p><strong>The good news is that most of these problems are relatively quick and easy fixes.

You can also use a URL shortening tool to help keep the QR Codes clean, less crowded, and easily scannable.</p><p><strong>Use case:</strong> Real estate agents use QR Codes on their property listings to provide potential buyers with virtual tours, floor plans, and additional details about the property. However, if all of this information is crammed into one QR Code, it can take longer to scan and may make potential buyers impatient or frustrated. Real estate agents need to consider what information is most relevant for each property and use QR Codes to link customers to the appropriate resources.</p><h2 class="wp-block-heading" id="7)-not-using-a-scannable-shape">7) Not using a scannable shape</h2><figure class=wp-block-image><noscript><img decoding=async src=https://lh7-us.googleusercontent.com/_Tp0XFCFnCm-c0sm_tmpAmqUpZM4vtfwouep0W3rhIfLwuxzu4GxVXS_heqQVDBsu2L-MJeQq_6m2wjysw1Vze3_AgG4EhhdVCJZh_9DM11r-NaHqSLnwRZXYNngwD8L9tttCktW4WZo6LmBfeZDJ1Y alt="A for sale sign with a stretched, rectangular QR Code"></noscript><img decoding=async src=data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7 alt="A for sale sign with a stretched, rectangular QR Code" data-src=https://lh7-us.googleusercontent.com/_Tp0XFCFnCm-c0sm_tmpAmqUpZM4vtfwouep0W3rhIfLwuxzu4GxVXS_heqQVDBsu2L-MJeQq_6m2wjysw1Vze3_AgG4EhhdVCJZh_9DM11r-NaHqSLnwRZXYNngwD8L9tttCktW4WZo6LmBfeZDJ1Y class=" lazyload"></figure><p><strong>Problem: </strong>QR Codes are available in different shapes and designs.

If you want to add a unique visual design element, consider using a custom QR Code generator to create a <a href=https://www.qr-code-generator.com/blog/how-to-create-a-brand-identity-with-qr-codes/ >branded QR Code</a> with your logo or preferred design. This way, you can maintain functionality and creativity in your <a href=https://www.qr-code-generator.com/blog/examples-of-qr-codes-marketing-campaigns/ >QR Code campaigns</a>. <a href=https://www.qr-code-generator.com/ >QR Code Generator</a> is an excellent tool for creating custom QR Codes with various designs and colors.</p><p><strong>Use case:</strong> Real estate companies sometimes use QR Codes on their “For Sale” signs to direct potential buyers to property information. While it may be tempting to use a unique shape or design for the QR Code, it’s important to remember that functionality and scannability should take priority. Using a custom QR Code generator can provide the best of both worlds, allowing for a unique design while also maintaining functionality.</p><h2 class="wp-block-heading" id="why-you-should-run-a-test-to-scan-qr-codes">Why you should run a test to scan QR Codes</h2><p>One of the best ways to prevent QR Code scanning malfunctions is to <a href=https://www.qr-code-generator.com/blog/qr-code-testing/ >run a test scan</a>. Simply put, a test scan is when you scan your QR Code with a QR Code scanner app or reader to make sure it works correctly before printing or distributing it. Below, we’ll cover some of the top reasons why you should conduct a test scan before publishing your QR Codes. </p><h3 class="wp-block-heading">Helps ensure the QR Codes are scannable</h3><p>QR Codes may be corrupted or generated incorrectly, which can affect their scannability. Testing the code before using it will help you identify any problems so that you can fix them before deploying the code. Remember, if the QR Code doesn’t scan for you, it won’t scan for your customers. The result? A frustrating experience for the customer and a lost opportunity for you.</p><h3 class="wp-block-heading">Verifies that the codes point to the correct destination</h3><p>You can use QR Codes to link to a variety of destinations, such as websites, social media pages, or even map locations. However, it’s essential to make sure that the code is actually linked to the correct destination before publishing it. Running a test scan allows you to verify that the QR Code takes customers to the intended destination. It can also help catch potential typos and URL errors in the case of Static QR Codes (which can’t be edited once they’re created).</p><h3 class="wp-block-heading">Identifies any compatibility issues</h3><p>Different QR Code scanners may use different technologies, so it’s important to test the code with a variety of different scanners to ensure that it’s compatible with all devices. This way, you can find critical compatibility issues and publish high-quality QR Codes. You can also test the code with different lighting conditions and angles to ensure that it scans smoothly in all situations.</p><h3 class="wp-block-heading">Helps you avoid costly mistakes</h3><p>If a QR Code doesn’t work, it can be costly to fix, especially if you have already deployed the code on marketing materials or products. Testing the code before using it can help you avoid these mistakes.</p><p>For example, if you’re using <a href=https://www.qr-code-generator.com/blog/qr-code-inventory-management/ >QR Codes for inventory management</a>, testing them beforehand can prevent your team from running into logistical errors in the future. This saves you time, money, and potential headaches.</p><h2 class="wp-block-heading">Master QR Code challenges with QR Code Generator PRO</h2><p>QR Codes are fantastic tools for marketers and businesses of all sizes. However, like any great technology, you may need to troubleshoot them from time to time. Issues such as poor design, incorrect generation, and compatibility problems can all hinder the effectiveness of your QR Codes. Luckily, fixing QR Code scanning issues doesn’t have to take long or be difficult—especially if you perform a test before publishing. </p><p>Ultimately, using a high-quality QR Code generator can help you avoid these issues and publish client-ready materials. </p><p><strong>If you’re ready to create impactful QR Codes that drive engagement, look no further than </strong><strong>QR Code Generator</strong><strong> PRO. </strong><a href=https://login.qr-code-generator.com/signup><strong>Create an account</strong></a><strong> to get started with a free trial.</strong></p></div></div></div></div><div class="container blog-author"><div class=row><div class="offset-xxl-2 col-xxl-8"><div class=blog-author__box><div class=row><div class="col-xl-3 col-md-4 blog-author__box--left-side"> <img class=blog-author__image src=https://qrcg-media.s3.eu-central-1.amazonaws.com/wp-content/uploads/2023/10/11063646/tobias-f.webp alt><div class=blog-author__social-media-wrapper> <a class=blog-author__social-media href=https://www.linkedin.com/in/tobiastadysiak/ target=_blank> <i class=icon-social-media-linkedin></i> </a></div></div><div class="col-xl-9 col-md-8 blog-author__box--right-side"><div class=blog-author__title> Author</div><div class=blog-author__name> Tobias Funke</div><p class=blog-author__description> Tobias Funke is Bitly’s Vice President of Product.
