Types of QR Codes Explained (2025 Guide with Examples & Uses) | Scanova

Quick Response (QR) Codes have evolved from industrial tracking tools to essential digital connectors that bridge the physical and digital worlds.

Originally developed by Denso Wave in 1994 for tracking automobile parts, these versatile types of QR Codes now facilitate everything from restaurant menus to trillion-dollar payment systems.

Understanding the different types of QR Codes and QR Code formats available today is crucial for businesses and individuals looking to leverage this powerful technology.

Whether you need static QR Codes for permanent links or dynamic QR Codes for flexible campaigns, this comprehensive guide explores every major QR format and application.

Let’s begin!

A. QR Code vs Barcode: What’s the difference?

The fundamental advantage of QR Code formats over traditional barcodes lies in their two-dimensional data encoding. This allows information storage both horizontally and vertically.

Ultimately, this enables QR Codes to hold significantly more data while remaining readable from any angle, but they differ in terms of design, information capacity, and applications.

Here are the key differences between QRs and barcodes:

1. Design

• QR Codes: QRs are square-shaped and consist of black squares arranged on a white background. They also have three smaller squares in the corners that help scanners identify the orientation of the code.

• Barcodes: Barcodes are typically linear, consisting of parallel lines of varying thickness and spacing. They can be one-dimensional (1D) or two-dimensional (2D), with 1D barcodes being more common in traditional retail settings.

2. Information capacity

• QR Codes: QRs can store much more information compared to traditional barcodes. They support a variety of data types, including alphanumeric characters, binary data, and special characters. This makes them suitable for encoding URLs, contact information, and multimedia content.

• Barcodes: Traditional 1D barcodes can encode a limited set of numeric or alphanumeric characters. 2D barcodes have higher information capacity than 1D barcodes but are generally not as versatile as QRs.

3. Data encoding

• QR Codes: QRs use a matrix pattern to encode data, allowing them to store information both horizontally and vertically.

• Barcodes: Barcodes use variations in the width and spacing of parallel lines to represent data in a linear format.

4. Readability

• QR Codes: QRs can be read from any angle and have error correction capabilities, allowing for successful scanning even if the code is partially damaged or obscured.

• Barcodes: Traditional 1D barcodes require a clear line of sight for accurate scanning. 2D barcodes may offer some error correction, but their readability can still be affected by damage or distortion.

5. Applications

• QR Codes: QRs are widely used in various applications, including marketing, advertising, product packaging, ticketing, and mobile payments. They excel in interactive and dynamic content delivery.

• Barcodes: Barcodes are commonly used in retail for inventory management, pricing, and product identification. They are prevalent on product labels and packaging.

6. Scanning devices

• QR Codes: QRs can be scanned using smartphones, tablets, and specialized QR scanners. Many modern smartphones come equipped with built-in QR scanning capabilities.

• Barcodes: Traditional 1D barcodes are typically scanned using laser-based scanners, while 2D barcodes may require specialized 2D barcode scanners.

C. Applications of QR Codes

QR Codes play a significant role in driving website traffic. Users can be sent directly to a webpage by merely scanning the code, providing easy access to the desired content.

You can use static QR Codes and dynamic QR Codes as per your use case. The basic difference between a dynamic and static QR Code is that a dynamic QR Code can be edited after creation, while a static QR Code cannot. Hence, static QR Codes are also called permanent QR Codes.

1. Drive Traffic to Website

QR Codes are used to drive website traffic as a simple yet effective method. By embedding a website URL in a QR Code, users can scan it with their mobile device and be taken directly to your site.

It eliminates the need to manually type in a web address, reducing potential errors and making the process quick.

You can even use a multi-URL QR Code if you have various websites.

This is particularly effective for printed media, where embedding clickable links is impossible. From posters to business cards and product packaging, these QR Codes instantly bridge physical media and your online presence.

2. Navigate to your location

Physical navigation becomes a breeze with location QR Codes, Google Maps QR Codes, and Waze QR Codes.

By scanning the QR Code, the user’s mobile device can launch a navigation app (like Google Maps or Waze) and provide directions to the desired location.

Creating a location QR Code can be a game-changer for businesses with physical locations. For example, retail stores, event venues, or restaurants. It also provides a way to guide people directly to places of interest, increasing footfall.

3. Deliver downloadable contact details

QR Codes can also carry contact information within them. These are called vCard QR Codes. When scanned, they show a landing page with details such as your name, mobile, website, company, designation, weblinks, and even a profile picture.

Plus, the page also has a ‘Save as Contact’ button. Hence, the recipients can easily save your contact with a simple click. No need for them to type anything. Easy, right?

4. Deliver documentation

QR Codes can contain links to PDF files, which can be downloaded and stored later. This is a practical solution for businesses that must share documents, manuals, reports, or e-books with their customers or stakeholders.

Businesses can also use an Excel QR Code generator like Scanova to optimize and fine-tune their business operations and more.

To deliver documentation, you can use a QR code for a Word document or Google Docs.

A PDF QR Code can be printed on product packaging or advertising material, giving users quick and easy access to information. QR Codes can significantly enhance customer experience and engagement, helping businesses share knowledge and add value.

You can also convert a PowerPoint presentation into a QR Code.

H. FAQs: Types of QR Code

1. How many different QR Codes are possible?

The number of possible QRs is extremely large, as the QR code format allows for a wide range of configurations and data sizes.

The number of possible QR codes can be calculated based on the different combinations of modules (black and white squares) within the code.

QRs come in different versions and sizes. The version of a QR defines its size, with larger versions capable of storing more data. Each version can have different error correction levels as well. 

The error correction level determines how much redundant information is included in the QR to tolerate errors and damage.

2. How many types of QR Codes are there?

QRs come in various types, categorized as static and dynamic. Static QRs include URL codes for website links, text codes for plain text information, and specialized codes for WiFi connections, emails, contacts, geolocations, phone numbers, SMS, and events. 

Dynamic QRs offer additional functionality, such as editability, analytics tracking, multi-URL redirection, password protection, and time sensitivity. Customization options include colored QRs and those incorporating logos. 

With their versatility, QRs cater to diverse needs, allowing for efficient encoding of information ranging from simple text to complex data, making them widely applicable across industries and purposes.

3. What are the two types of QR Codes?

The two primary types of QRs are static QR Codes and dynamic QR Codes.

I. Static QR Codes

• Characteristics: These QRs contain fixed, unchangeable information.
• Use Cases: Commonly used for straightforward data like website URLs, text, contact information, WiFi network details, and more.
• Limitations: Once generated, the encoded information cannot be modified without creating a new QR Code.

II. Dynamic QR Codes

• Characteristics: These QRs allow for flexibility and can be edited or updated after creation.
• Use Cases: Ideal for scenarios where the encoded information may change, such as marketing campaigns, promotions, or dynamic content like event details.
• Advantages: Offers features like analytics tracking, the ability to redirect to different URLs based on conditions, and the option for time-sensitive content.

4. Are any 2 QR Codes the same?

The probability of two randomly generated QRs being the same is extremely low. The uniqueness of QRs is a result of the vast number of possible combinations and configurations they can have. 

The QR standard includes different versions, sizes, and error correction levels, contributing to a large space of potential QR variations.

However, it’s important to note that the uniqueness of QRs relies on their random generation and adherence to the QR standards. If a QR is manually generated with specific data, the chance of generating an identical QR increases.

In practice, QR generation tools and algorithms are designed to produce unique codes for different sets of data.

The risk of unintentional collision (two different sets of data producing the same QR Code) is considered extremely low due to the complexity of the encoding process and the large space of possible configurations.

5. What is the most common type of QR Code?

The most common type of QR is the standard static QR Code that typically contains a URL. 

These types of scan codes are widely used for various purposes, including marketing, advertising, and providing convenient links to websites. 

When people scan these QRs with their smartphones or other devices, they are directed to the encoded URL, which could lead to a product page, promotional offer, or any other online content.

Static QR codes with URLs are popular due to their simplicity and ease of use. They are easily generated and widely supported by QR reader apps on smartphones.

Businesses often use them for connecting users to their websites, online resources, or specific landing pages, making them a prevalent choice for a broad range of applications.

6. Is a QR Code 1D or 2D?

A QR is a two-dimensional (2D) matrix barcode. Unlike one-dimensional (1D) barcodes that consist of parallel lines of varying widths, a QR Code is a square or rectangular pattern of black squares arranged on a white background. 

The information in a QR is encoded both horizontally and vertically, allowing it to store a significant amount of data compared to traditional 1D barcodes.

The term “2D” signifies the two-dimensional nature of QR Codes, distinguishing them from the linear structure of 1D barcodes.

Summing Up

QR Codes are growing fast, and they’re not going anywhere.

From simple static codes that hold fixed info to advanced dynamic codes that let you track scans and update links, each type serves a purpose. They’ve become a must-have tool for businesses, marketers, and even everyday users.

In 2025 alone, people scanned QR Codes over 41 million times – that’s a 433% jump in just four years. Clearly, more people are using them every day.

As new QR Code formats and uses keep popping up, it’s important to know which type works best for your needs.

Whether you’re running a campaign, sharing a product, or streamlining a process, picking the right QR Code makes all the difference.

Now’s the time to try them out. Use the format that fits your goal, and make the most of this smart way to connect the physical world with the digital one.
