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.
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.
