How to Create a QR Code with React

In today's digital age, traditional practices such as exchanging business cards are gradually becoming outdated. Business cards can easily be misplaced or lost, and manually entering contact information can be prone to errors. Thankfully, there is a more efficient and convenient solution: QR codes. QR codes, short for Quick Response codes, allow you to encode various types of information that can be scanned by smartphones, eliminating the need for manual input.

The Downside of Business Cards

Business cards have long been used as a means of exchanging contact information in both professional and social settings. However, they come with several downsides. They can easily run out, causing inconvenience when networking with numerous individuals. Moreover, physical cards can be misplaced or forgotten, rendering the information contained within them useless. Additionally, typing in contact information manually can lead to errors, making it difficult for recipients to reach out. These challenges have sparked a need for a more efficient and reliable alternative.

Introduction to QR Codes

QR codes provide a simple and effective solution to the limitations of traditional business cards. These codes are two-dimensional barcodes that can be scanned and interpreted by smartphones equipped with a QR code reader. They can store various types of information, including website URLs, contact details, product information, and much more. By simply scanning a QR code, users can quickly access the encoded data without the hassle of typing or manual input.

Benefits of Using QR Codes for Contact Information

4.1 Convenience and Ease of Use

QR codes streamline the process of sharing and accessing contact information. Rather than relying on the exchange of physical business cards or the need to manually enter details, individuals can now simply scan a QR code to save the contact information directly to their devices. This convenience makes networking and communication more efficient and enhances the user experience.

4.2 Cost-effectiveness

Printing business cards can be costly, especially when large quantities are required. On the other hand, creating and sharing QR codes is a cost-effective digital alternative. Businesses and individuals can easily generate QR codes using free online tools or libraries and share them through various digital platforms, eliminating the need for physical cards altogether.

4.3 Elimination of Contact Errors

Manual input of contact information can often lead to mistakes, such as incorrect phone numbers or email addresses. QR codes eliminate the risk of transcription errors, ensuring that the recipient receives accurate and error-free contact details. This not only saves time but also prevents miscommunication and frustration.

4.4 Environmental Friendliness

In today's world, where sustainability and environmental consciousness are paramount, QR codes offer an eco-friendly solution. By reducing the reliance on paper-based business cards, QR codes help to minimize waste and contribute to a more sustainable business practice.

How to Create a QR Code with React

Creating a QR code with React is a straightforward process that can be accomplished using libraries such as QR Code React. By following a few simple steps, you can integrate QR code functionality into your React project.

5.1 Setting Up a React Project

Before creating a QR code with React, you need to set up a new React project. This can be done using the create-react-app command, which initializes a new project with the necessary dependencies and folder structure.

5.2 Installing the QR Code React Library

To incorporate QR code functionality into your React project, you will need to install the QR Code React library. This can be done using the npm install command, which adds the library as a dependency to your project.

5.3 Using SVG or Canvas

QR codes can be rendered using either SVG or Canvas, each with its own advantages and disadvantages. SVG provides a scalable and responsive solution, while Canvas allows for more complex customization. Depending on your requirements, you can choose the appropriate method for rendering QR codes in your project.

Incorporating the QR Code Component

Once the necessary setup and installations are complete, you can incorporate the QR Code React component into your project. By importing the component and passing the required values, such as the URL or contact information, you can render a functional QR code within your React application.

Adjusting the Size of the QR Code

The size of the QR code can be adjusted to ensure optimal visibility and scanning capabilities. By modifying the size parameter in the component, you can control the dimensions of the QR code to fit your desired layout or device screen.

Testing the QR Code

After creating and adjusting the QR code component, it is crucial to test its functionality. By running your React project and opening it in a browser, you can scan the generated QR code using a smartphone equipped with a QR code reader. This will allow you to verify that the QR code accurately redirects to the intended URL or displays the correct contact information.

Hosting QR Code on GitHub Pages

One of the advantages of utilizing React is the ability to host your projects for free on GitHub Pages. By deploying your QR code project on GitHub Pages, you can easily share the generated QR code URL with others. This provides a convenient way for individuals to access your website or contact information without the need for physical cards or lengthy URLs.

Alternative Uses of QR Codes

In addition to contact information, QR codes can be utilized in various other contexts, expanding their versatility and functionality.

10.1 Product Sharing and Recommendations

QR codes can be generated for specific products, enabling users to easily share product details and recommendations with their friends and contacts. By simply scanning the QR code associated with a particular product, recipients can access relevant information, images, reviews, and purchase links. This feature opens up new avenues for product promotion and customer engagement.

10.2 Event Badges

QR codes are extensively used in event management, particularly for issuing electronic badges. Attendees can receive personalized badges containing a unique QR code, which grants access to various event areas, workshops, or sessions. This not only simplifies the registration process but also enhances event security and tracking mechanisms.

10.3 Offline Usage and Progressive Web App Integration

QR codes can be leveraged for offline usage, allowing users to access content even without an internet connection. By integrating QR codes into a progressive web application (PWA), users can download and cache relevant content, such as articles or product catalogs, for offline viewing. This feature enhances the user experience by providing uninterrupted access to information.

10.4 Other Creative Applications

The possibilities for utilizing QR codes are virtually limitless. They can be incorporated into marketing materials, packaging, billboards, and even art installations. QR codes serve as a bridge between the digital and physical worlds, enabling interactive experiences and adding value to various industries.


In conclusion, QR codes present a modern and efficient alternative to traditional business cards. By incorporating QR code functionality into your React project, you can simplify the sharing and accessing of contact information. Whether for personal use or business purposes, QR codes offer a convenient, cost-effective, and environmentally friendly solution. With the ability to host QR codes on platforms like GitHub Pages, you can easily share your QR code URLs and ensure that recipients have quick and seamless access to your website or contact information. Explore the versatility of QR codes and discover the myriad of creative applications they offer, revolutionizing the way we share and consume information.
