The short version
Open the Camera app and point at the QR — iOS detects it automatically.
Step-by-step
-
Step 1
Open the Camera app
Tap the Camera icon on your home screen, lock screen, or in Control Center. You don't need to switch to a special mode.
-
Step 2
Aim at the QR code
Hold your iPhone so the QR is fully in the frame. The camera focuses automatically — you don't need to tap the shutter or take a photo.
-
Step 3
Tap the yellow link banner
A yellow notification with the QR's destination appears at the top of the screen. Tap it to open the link, contact, Wi-Fi join, or other action.
If it doesn't work
- If nothing happens, open Settings → Camera and confirm "Scan QR Codes" is on (it usually is by default).
- iOS 10 and earlier don't have a built-in scanner — install a free reader from the App Store.
- Try moving closer or improving the lighting if the camera can't lock on. The QR should fill at least a third of the frame.
- Reflective or curved surfaces (like a screen behind glass) can break detection — tilt the phone slightly to remove glare.
Frequently asked questions
Do I need to download a QR scanner app on iPhone?
No. Since iOS 11, the built-in Camera app scans QR codes natively. Open Camera, point at the QR, and tap the link banner that appears.
Why isn't my iPhone scanning the QR code?
Most often: the QR is too small in the frame, lighting is poor, or there's glare on a screen. Less common: "Scan QR Codes" is disabled in Settings → Camera. Confirm it's on, then try moving closer.
How do I scan a Wi-Fi QR code on iPhone?
The same way as any other QR: open Camera, aim at the Wi-Fi QR, and tap the banner. iOS will prompt you to join the network — tap "Join" and you're connected.
Can I scan a QR code from a screenshot or saved photo?
Yes, since iOS 16. Open the photo in the Photos app and a QR icon appears in the bottom-right when iOS detects one — tap to open the link.
