About QR code

What is a QR code?

In the simplest terms, it is a 2D barcode that encapsulates data, making it readily accessible. QR stands for Quick Response, reflecting its ability to quickly retrieve information. Any smartphone, tablet, or other device type equipped with a camera can scan and interpret QR codes, often aided by a specific app.

What are the benefits of using QR codes?

Quick response codes simplify numerous processes. For instance, a quick scan can direct you to a product’s website or mobile-friendly landing page to collect feedback or redirect users to your social media profiles.

Also, it can prevent clients from manually entering phone numbers or WLAN passwords, with a scan granting immediate access. Quick response codes are appealing for their speed, but their usage should be justified by real user benefits.

Using a custom QR code generator, you can enhance your marketing materials and make digital content instantly accessible. The user benefits should be clear. So, why wait? Generate your own QR code with our seamless service now!

How do I scan the QR code?

You can scan two-dimensional barcodes using a smartphone or tablet and an app to scan and then process them. This is done in 4 steps:

  • Open the camera app.
  • Point the camera at the code so it’s fully visible on the screen.
  • Wait for the prompt.
  • The application executes your code and offers you, for example, the ability to consult the integrated URL.

Do QR codes expire? How long are QR codes valid?

No expiration ā€“ Static QR codes are permanent. Once generated, they work indefinitely as long as the linked content (e.g., a website or file) remains active.

Dependent on Subscription ā€“ Dynamic QR codes rely on a short URL or redirection service that stays active only while your subscription is valid.

If your paid subscription ends, the QR code may stop working, and users will see a message like: “This QR code is no longer active.”

Is it secure to use an online QR code generator?

Rest assured, using ViralQR, a custom QR code creator, involves no risks. We guarantee that your data will not be stored or reused in the future.

We ensure user data stays secure by implementing McAfee Total Protection on our QR code generator website. Achieving SOC 2 Type 2 certification further underscores our commitment to security, availability, and trust, positioning ViralQR as a reliable and secure platform to make a QR code online.

Q&A

Common Questions About QR Codes

Core Concepts and FeaturesšŸ’”

What is a QR code generator?

It is an instrument to be used to generate QR codes, as well as manage and track them. So, you’ll make up your customized quick response code and adapt it to your personal needs. You can apply this tool to accumulate codes that give access to different types of information or enable the execution/activation of particular tasks.

What information does a QR code hold?

The data stored in a QR code depends on its intended purpose. The first step in generating a QR code is to determine its purpose. It can include:

  • Web addresses (URLs and websites)
  • vCard data (virtual business cards for quick contact details addition)
  • Contact information (phone numbers or email addresses)
  • Calendar events
  • Plain text
  • Wi-Fi network passwords
  • Cryptocurrency addresses
  • Standard SMS messages
  • Files, such as PDFs or images
  • Mobile-friendly built-in landing pages (e.g., for reviews or app downloads from the App Store or Google Play)
  • Business pages
  • Link trees
  • Multiple social media links (Instagram, Facebook, Twitter, etc.)

All this data can be easily readable by smartphones and mobile phones equipped with a reading application.

Can I use the generated QR codes for commercial purposes?

Of course. One of the purposes of a two-dimensional barcode is to attract clients to your business. So, commercial purposes are always welcome, and we are here to assist you in accomplishing your business-related goals.

Can I make QR codes free?

Typically, free QR code generator that generate free QR codes come with functionality, settings, and scanning limitations. That’s why we offer our customers exclusive access to the full suite of features during a 14-day trial period. This includes advanced functionality, extensive customization options, and detailed analytics to track the performance of generated QR codesā€”all available for a nominal fee.

Our subscribers are eligible for a 14-day trial for $1.49 only. If you create a dynamic QR code within your trial period (high-resolution and trackable is meant), you can continue to use and edit it after upgrading your subscription.

You’re eligible to test our QR code generator right now! The trial period is available in two plans:

  1. Basic Access Plan ($1.49): Selective access with limited features.
  2. Full Access Plan ($1.99): Complete access to all features during the trial period.

You can find more details about our plans on theĀ pricing page.

What do static and dynamic types mean?

A static code is a set of symbols containing fixed information that cannot be changed.

Dynamic codes, however, can be updated, edited, and modified. Rather than storing large amounts of information in code, they point to Short URLs that capture the data, such as a point on Google Maps. Dynamic codes include links to social media pages and sending orders through a code on restaurant menus that one can access with a QR code scanner app on a mobile device.

Managing QR Codes and Subscriptions šŸ“Š

How can I manage expiring QR codes for marketing campaigns?

With our online QR code maker, you can assign dynamic QR codes an expiration date to match the length of a marketing campaign. Once the campaign ends, it can display a custom message like: “QR code has a schedule of scans. Currently, the QR code is not available for scanning.”

Can I track how many times my QR code is scanned?

With our dynamic QR codes scan tracking, you can access a wealth of detailed analytics. These include the number of scans, the location, and the type and operational system of the device used. This comprehensive data helps you truly understand your audience and fine-tune your campaigns.

How does an online QR code generator manage your codes?

Our platform provides an intuitive dashboard to efficiently manage all the QR codes you create using our custom QR code builder.

With our tool, you can:

  • Create and name folders to organize your codes
  • Track analytics for all QR codes created
  • Pause and reactivate dynamic QR codes as needed
  • Update the target information anytime
  • Download QR codes in your preferred format and size

Once a QR code is created, you can easily sort, move it to a folder, edit, or delete it.
So, have no worriesā€”you’ll have an extremely convenient approach to managing your quick response codes, both dynamic and static.

What does "Scan Quota Exceeded" mean?

There are 2 possible reasons for this message:

  1. The code creator has set a limit on the number of scans, which has now been exceeded. You must edit the settings and remove the limit to allow the code to be scanned.
  2. This means that the code created within the Basic Access Plan has exceeded specific scans. It assumes that purchasing a 12-month Plan subscription is necessary to make your quick response code active again.

Scanning & Troubleshooting āš™ļø

Can my smartphone scan QR codes?

You just need to use the Camera app to scan any QR code. The QR code reader may not be built into your Camera app if it doesn’t work. So, you’ll need to download a dedicated app for your mobile device. To use the QR code reader on your phone, be sure to stick to the following points:

  • Open the scanning app on your phone.
  • Hold your phone over the code and ensure it is visible on the screen.
  • The phone should automatically scan it.
  • If not, click the capture button to take an image.

How to scan a code on an iPhone:

  • Open the Camera app.
  • Hold your iPhone over the codification image to scan it.
  • Mark the notification that appears on your screen.

Is there a scan limit?

Our QR code creator has no limits when it comes to scanning. Your QR code can be scanned unlimited times, regardless of your project size or the amount of scan data collected. You can also set a custom scan limit for a specific dynamic code if desired. However, within the trial period, the Basic Access Plan includes scan statistics collection for the first 10,000 QR code scans, while the Full Access Plan has no such limitsā€”just like our main 12-month Plan. If you’d like to access more in-depth stats, consider upgrading your Plan.

Why is my QR code not working?

When creating a QR code, quality makes the difference between a code that scans and one that doesn’t. Many beginners create custom QR codes and then change the size by resizing them. They often enlarge it to a better measure, but still, a low-resolution picture increases blur.

  1. Blurry or distorted QR code image makes scanning impossible.
  2. Its size is too small. For readability, the code should be at least 2×2 cm (0.8×0.8 inches).
  3. Low contrast. Use a high contrast between the code and the background (e.g., black code on a white background).
  4. The QR code is damaged.
  5. Logo or design elements are interfering. Custom QR codes with logos or art can become unreadable if not generated correctly.
  6. “Quiet zone” is too small. There should be a margin or “quiet zone” around the QR code to make it scannable.
  7. Inadequate lighting or angle. Make sure the code is scanned in good lighting without glare and from a proper angle.
  8. Unstable internet connection.
  9. Server is down. If you’re using dynamic QR codes, ensure the service managing it is active and functioning.
  10. The camera or QR scanner app is not working.

Try scanning the QR code with multiple devices and apps. If the issue persists, recreate the unique QR code with proper settings and ensure it meets the recommended standards.

Can I scan a code without using an app?

Previously, a scanning app was required, but now the camera app on your mobile phone is sufficient. It is no longer necessary and can be done entirely from the camera on your mobile devices.

Why is it impossible to have my QR code scanned?

If your code is slightly damaged, it can still be scanned as long as the data loss does not exceed the highest error correction level (30%). If the QR code is intact but nothing happens, your phone needs to download a scanning application. If your smartphone opens a window with an internet link, then it means that the reader is integrated.

What should I know before printing my code?

Getting a quick response code for your products is simple. But before you print your new QR code, you’d be concerned about technical aspects such as color contrast (they matter a lot), the code’s size, and your information’s credibility/accessibility. Pay attention to your picture quality and resolution. Make sure you create a scannable QR code. Focus on code placement to grab more scans for commercial usage in your mobile marketing campaigns.

Before printing your new QR code, keep these tips in mind to ensure it works effectively:

  1. Test readability. Make sure your QR code is readable by testing it with multiple scanning apps.
  2. Don’t overdo customization. Avoid excessive design customization to keep the code recognizable.
  3. Pick the correct size. Choose a size appropriate for where and how it will be scanned.
  4. Check your content. Ensure the linked content is live, and avoid broken links or outdated information.
  5. Use high-quality images. JPG and PNG formats work well for small-scale printing.
  6. Select the suitable printing material. Create a sample and test the code’s readability before mass printing.
  7. Place codes within reach. Ensure QR codes are positioned where users can quickly scan them.
  8. Consider scanning time. Choose appropriate marketing materials to prevent delays during scanning.
  9. Limit the number of codes. Avoid using multiple QR codes in the same space to prevent confusion.
  10. Include a clear CTA. Let users know what to expect after scanning (e.g., “Scan to access our latest deals!”).
  11. Always test before finalizing. Double-check the code’s performance before mass printing.

Editing and Customization Options šŸŽØ

Can I change the destination of a code after printing?

If you’ve created the dynamic QR code, modifying or changing the it’s target URL will surely be possible. But please note if you get a QR code for a website and its destination is the website URL, it cannot be changed to another type such as vCard or Wi-Fi.

Can I generate a custom QR code with a company logo?

Yes, our QR code maker offers various design options to help you create QR codes with a logo and your brand colors. You can further personalize your code by selecting a frame, pattern, and shape, ensuring it aligns perfectly with your brand identity.
Rest assured that with our service, you will create a QR code with a logo that will be fully scannable.

Can I change the size and file format of my QR code image?

With our easy QR code creator, you can choose the code image size, error correction level or leave it as default, and download it in .svg, .png, .jpeg or PDF file format. To do this, you just need to log in to your account and visit your dashboard of generated QR codes.

What graphic formats does ViralQR support?

You can create a QR code online from a browser on a PC or any mobile device (Android and iOS devices) and download it in four image formats: .svg, .jpeg, .png, and pdf files. Our tool allows you to choose the image size and error correction level.

Best Practices and Design Guidelines šŸ¦„

What is the minimum size of a QR code?

When you create a QR code image, the minimum size is 2 x 2 cm (0.8 x 0.8 in). So you’ll encounter no issues when you create it with our professional QR code generator.

What's with the white border around the QR code?

The so-called “quiet zone” is located around the QR code print when it’s forged to separate it from anything else in its surroundings. This helps scanning devices recognize the code accurately without interference from nearby elements.

What is the maximum size of a QR code?

There is no strict maximum size for a QR code, but its dimensions should be proportional to the scanning distance. A general rule is that the code’s size should be 1/10th of the intended scanning distance (e.g., a 10 cm code can be scanned from 1 meter away). For practical purposes, they can be printed as large as needed, such as on billboards or posters, as long as the resolution and contrast remain high enough for reliable scanning.

Does the color of the code influence its readability?

As a branded code generator, we understand that colors play a crucial role in shaping the perception of your brand identity. Therefore, when creating a QR code, we must balance branding and code readability.

It’s essential for coding that the dots are darker than the background. Therefore, for reliable scanning, ensure high contrast between light and dark elements. In such a way, their sensors would optimally be able to catch and estimate the reflected light. The difference in reflection between light and dark elements is called the print contrast signal (PCS). If you don’t want to take chances with scannability, ensure it does not exceed the 80% rate.

Security, Privacy, and Compliance šŸ”’

Is it safe to use your QR code generator?

Yes, we take the privacy and security of your data seriously. Users’ informationā€”such as QR code content, generated codes, or payment dataā€”remains strictly protected. We do not share personal data with third parties, and we comply with relevant privacy laws, such as GDPR.

Additionally, sensitive payment information is processed securely through trusted payment providers, without being stored on our servers.

Here’s how we protect your data:

  • We encrypt all login credentials and authenticate securely. Unauthorized access to accounts is actively prevented with monitoring and protective measures.
  • Data used for QR codes is solely for generating codes and is not tracked or retained once the code is created.
  • Payment data is handled securely through encrypted channels by providers like Checkout.

Can I limit access to content for people under 18 years of age?

Yes, you can add an age verification feature. If you turn the slider on, users must enter their date of birth to confirm they meet the specified age requirement. Instant access to certain content will be denied if the date entered indicates they are under the required age.

What if someone scans a QR code during server downtime?

In the rare event of a server outage, dynamic QR codes may temporarily stop redirecting to their intended destination. However, we continuously monitor our servers and maintain an uptime of over 99.9%, ensuring uninterrupted service and reliability.

Can I set a password using a QR code?

You can set up a password that users must apply after scanning the code to access the content.

Can I create a QR code without ads?

We do not display ads after scanning a QR code. Our focus is on providing a seamless user experience, ensuring that the code directs users only to the intended content or destination without interruptions or unwanted advertisements.

Some reader apps may display ads within their interface, but these ads are not connected to us.

Are you GDPR compliant?

Yes, our platform is entirely GDPRĀ  compliant. We do not store any personal data without the user’s explicit consent. Additionally, all IP addresses are anonymized to ensure they cannot be linked to any individual. For more details, please visit our Privacy Policy page.
