QR code basics

What is a QR code?

A QR code is a type of two-dimensional barcode that can be read using smartphones or dedicated QR reading devices. These codes store information in a machine-readable optical label, which can include text, URLs, or other data. QR codes have become popular for their ability to hold a significant amount of data and their ease of use.

How do QR codes work?

QR codes work by storing information in a two-dimensional pattern of black and white squares. When scanned, the device interprets the pattern using error correction techniques to retrieve the stored data. This data is then converted into a usable format such as a website URL, a digital business card, or a position on a map depending on the encoded information.

Will QR codes replace barcodes?

Yes, eventually QR codes will replace barcodes. QR code can easily store the information traditionally contained in a linear barcode. Starting in 2027, all retailers will have to switch to 2D code scanners for checkout.

What is the minimum size of QR code?

The minimum size of QR codes that we recommend is 3 cm x 3 cm (1 inch x 1 inch). If you’re not sure, it’s better to print them larger than smaller

What is the maximum data capacity of a QR code?

A QR code’s data capacity varies based on the QR code type of data encoded and the version used. It can store up to 3,000 alphanumeric characters, providing ample space for URLs, text, or other information. For numerical data, a QR code can hold up to 7,089 characters.

Can QR codes function if they are partially damaged?

Yes, a partially damaged QR code may still be operational thanks to built-in error correction capabilities. This means that even if a QR code is slightly damaged or obscured, there’s a good chance it can still be scanned successfully. However, the extent of recoverability depends on the level of damage and the error correction level used when creating the QR code.

Is it possible to have a QR code in white?

QR codes are typically black on a white background for maximum contrast and scannability. However, the colors can be inverted (white on a dark background) as long as there is sufficient contrast for scanners to read the code. It’s crucial to test the scannability of inverted QR codes across different devices and lighting conditions.

What does it mean to have a QR code in vector format?

A QR code in vector format means the code is created as a scalable vector graphic (SVG), allowing it to be resized without losing quality. Vector QR codes are ideal for printing purposes because they can be scaled to fit any size from small cards to large billboards while remaining sharp and scannable.

Have QR codes become obsolete?

Far from being a thing of the past, QR codes continue to evolve and find new applications in our increasingly digital world. Their usage has expanded, particularly in areas like contactless payments, marketing, and information sharing, proving their enduring relevance and utility.

Types and uses of QR codes

What is the difference between static QR codes and dynamic QR codes?

The difference between static QR codes and dynamic QR codes is that you can’t change static QR codes once you create and print them. If you want to change the data in the QR code because you want to update it or you made a mistake, you’ll have to generate and reprint a new one. Dynamic QR code is nothing like that. You can change them in real-time as many times as you need.

When to use dynamic QR code?

Dynamic QR code is your only choice when you need the flexibility to update the content of your QR and adjust your campaigns based on actual results – everything without losing time and energy reapplying or reprinting the QR code designs.
Also, dynamic QR codes are the way to go when you need to have scan tracking information.

What are QR codes used for?

QR codes are used for a variety of purposes, primarily aimed at providing quick and effortless access to information.
They are commonly used in advertising to direct consumers to a website or app, in restaurants to provide menu QR code, in event tickets for easy entry, and in retail for product information or promotions.
They can also be used to encode contact information, Wi-Fi network details, or other types of data for easy sharing and access. See all QR code types available.

Why should businesses use QR codes on business cards?

Digital business card QR codes make sharing contact information effortless and digital. When scanned, these QR codes can direct individuals to web pages that showcase professional profiles, contact details, or even a portfolio, ensuring that your new connections have everything they need to reach out or learn more about your work.

What’s the difference between a landing page and a website QR code?

A landing page QR code is designed to direct users to a specific, targeted page, whether it’s for a promotion, event, or special offer. A website QR code typically links to a homepage or main site. With QRCodeKIT, you can customize both to align with your goals.

Where can I use my menu QR code?

Anywhere your customers interact with you. Print it on table tents, napkin holders, packaging, flyers, or even digital displays. Your menu QR code works in restaurants, cafés, food trucks, hotels, and pop-ups—basically anywhere food is served and phones are used.

What social media platforms can I link to with a social media QR code?

You can link to any social media platform, including Instagram, Facebook, Twitter, LinkedIn, YouTube, TikTok, and more. Combine all your profiles into one QR code.

How does an App Store QR code work?

An App Store QR code detects the user’s device and opens your app listing in the correct store, Apple App Store for iOS or Google Play Store for Android, instantly.

Creating and customizing QR codes

How do I make a QR code with a logo?

You can make a QR code with logo on QR Code KIT, easily. You can actually completely customize your QR code: change colors, adjust the shape, insert an image, and, of course, embed a logo. You just have to upload your logo to our system: we recommend simple, icon-based logos to keep them readable also at small sizes. Read more about QR codes with logos.

Can a QR code have a different shape?

Traditionally, QR codes are square in shape as it allows for the most efficient use of space to store data. However, a QR code can have some stylistic modifications, such as rounded corners or embedded logos, while still remaining functional. It’s important to note that these modifications should be made carefully to not interfere with the readability of the code. Learn more about QR code customization.

How long do custom QR codes last?

Custom QR codes last forever. Seriously! Custom QR codes don’t expire. Remember that if you created a personalized QR with a QR code maker like QRCodeKIT (we recommend dynamic a QR codes since you can update them how many times you want and track them), you would need a subscription to keep it working.

How do you make QR codes look cool?

You make QR codes look cool by customizing them. Apply your brand colors to the QR codes, or look for colors with good matching contrast. Add your logo in vector format and set it to take 30% of the QR size.

Use a plain white background with some space around the code, and frame it with your call-to-action. With our dynamic QR code generator you have access to QR design with all plans. Discover more about custom QR code.

What considerations should be made when designing a QR code for a business card to ensure optimal scanning?

When designing a digital business card QR code, ensure the QR code is clearly visible and not too small to scan. Maintain a balance between aesthetic appeal and functionality by choosing contrasting colors and a simple design that doesn’t overshadow the QR code’s scannability. Additionally, testing the QR code on various devices before printing is crucial to ensure compatibility and ease of use.

Can I customize the design of my QR code?

Yes, you can! QRCodeKIT allows you to fully customize your QR code with logos, colors, frames, and calls-to-action, so it fits perfectly with your brand and the message you want to convey.

What is an artistic QR code and why should I use one?

An artistic QR code integrates visual design—colors, textures, logos, or backgrounds—into the QR structure while remaining scannable. These codes grab attention, reinforce brand identity, and drive engagement far better than standard black-and-white versions.

How does QRCodeKIT ensure artistic QR codes stay functional?

More than 90% of the artistic QR codes generated with AI are fully scannable. However, at QRCodeKIT we always recommend testing your QR code with a real scan before printing. This ensures that the final design works correctly in the context where it will be used and avoids surprises during production.

Where can I effectively use artistic QR codes?

They perform especially well in visually rich environments like product packaging, posters, business cards, café menus, or advertising materials. Because they blend with design rather than stand out unappealingly, they help elevate your brand while still delivering reliable scans.

Tracking and analytics

How does integrating a QR code with Google Analytics benefit my business?

Integrating a QR code with Google Analytics allows businesses to track scan statistics and analyze user engagement. This data provides insights into how customers interact with your QR code, enabling you to refine marketing tools, improve user experience, and measure the effectiveness of your campaigns.

How can scan statistics from QR codes improve my marketing strategies?

Analyzing scan statistics from your QR codes can provide valuable insights into customer behavior and campaign performance. By understanding which QR codes generate the most scans, you can identify what content resonates with your audience and adjust your marketing strategy accordingly for better results.
