How do I use my phone to scan a QR code?

Generally, you can scan a QR code using your phone's camera app. Open the camera and point it at the QR code, centering it on the screen. Hold it steady until a link or notification pops up. Tapping this link will take you to the associated content. If your camera app does not automatically detect the code, you might need to use a dedicated QR code scanner app or a feature like Google Lens on Android or Code Scanner on iPhone/iPad.
