QR codes are a type of two-dimensional barcode that can be scanned with a smartphone or other device to access information or perform an action. They are frequently employed in applications such as marketing and advertising, event ticketing, and others when it is required to swiftly access information or carry out an activity using a mobile device. 

Following are some instances of how QR codes could be applied in a React application: 

  • Marketing and advertising: QR codes can be used to point consumers to a particular website or social media account, as well as to access exclusive deals or discounts. 
  • Event ticketing: QR codes can be used to create electronic tickets for events, allowing attendees to enter the venue by simply scanning their tickets. 
  • Product packaging: QR codes can be scanned to get details about a product, like its ingredients or usage directions. 
  • Access control: QR codes can open doors to places off-limits to the general public, including office buildings or VIP zones at sporting or musical events. 

The npm package "react-QR-code" enables you to create QR codes in React applications. It is a straightforward, lightweight, and user-friendly package that offers a React component for creating QR codes.
