In iOS 11, the native camera app includes functionality that allows you to scan QR codes and access QR code content like URLs without having to download a third-party app.
Here's how to scan a QR code when you run into one:
- Open the Camera app on the iPhone or iPad.
- Make sure you have adequate lighting so the camera can pick up the QR code.
- Align the camera with the QR code.
That's all there is to it. From there, the camera will read the QR code and provide you with a notification to access whatever it contains.
QR codes can include contact information, calendar events, website links, phone numbers, email addresses, Wi-Fi information, and more, so they can be pretty handy, and it's nice to have the built-in scanning feature available when you need it.
