QR codes allow users to easily access online content through their smartphones. A QR code contains encoded information that can link to a website, contact information, or other file. QR codes help reduce friction for users by providing a simple scan rather than typing a long URL. Key advantages of QR codes include quickly sharing information publicly, leading users to specific web pages, and improving conversion rates by seamlessly connecting offline and online experiences. The structure and positioning of elements within a QR code, such as the three corner markers, allow it to be properly oriented during scanning.
