A QR code is a two-dimensional bar code that can be read by a camera or a device with a special bar code reader. The QR code is usually used to launch a website or trigger a specific operation within an application.
How to scan QR codes on an iPhone
- Open the Camera app
- Point your camera at a QR code
- Tap the popup that appears
The iPhone Camera app automatically detects QR codes and pops up a tooltip to allow you to launch the code whenever you’d like.
Besides, you can also add a dedicated QR code scanner to your Control Center. The dedicated scanner is helpful for scanning QR codes in dark environments, as it enables you to use your camera’s flash as a light to illuminate the code.
