Most modern devices have built-in QR code scanning capabilities in their camera apps. • Point your camera at the QR code, making sure it's clearly visible within the frame. • Hold steady for a few seconds. The camera should automatically recognize and scan the QR code. • Tap the notification or link that appears on your screen. This will usually take you to the information or action associated with the QR code, such as a website, video, or contact information.
