How to Scan a QR Code on iPhone

Every iPhone that runs iOS 11 or later (released in 2017 — effectively every iPhone still in common use) can scan QR codes directly through the built-in Camera app, with no separate scanner app required. Here's exactly how it works, and what to do if it isn't working the way you expect.

How to scan a QR code on iPhone

1. Open the Camera app directly from the Home Screen or Control Center — you do not need a separate QR scanner app.
2. Point the camera at the QR code, holding the phone steady, roughly 4-8 inches away for a small code or further back for a larger printed code.
3. Wait for a yellow-bordered notification banner to appear at the top or bottom of the screen showing the destination link.
4. Tap the notification banner to open the link in Safari (or whichever browser is set as default).

You do not need to tap the shutter button or take a photo — the Camera app detects and decodes QR codes automatically, live, without capturing an image. If nothing happens after a couple of seconds, the most common cause is a Control Center or Settings toggle disabling the feature (see below), not a problem with the code itself.

If nothing happens: check that QR scanning is enabled

QR code scanning in the Camera app can be turned off. To check: open the Settings app, scroll to Camera, and make sure "Scan QR Codes" is toggled on. This setting is on by default, but can be switched off by a previous owner, a parental-control profile, or accidentally during a settings reset.

Faster access: Control Center

Many iPhones have a QR code scanner shortcut available directly in Control Center (swipe down from the top-right corner, or up from the bottom on older models). If you see a small QR-code-shaped icon there, tapping it opens a dedicated scanner view — functionally identical to using the regular Camera app, just one swipe faster.

Scanning from within Safari or Control Center directly

If Control Center's QR scanner isn't showing up, it can be added: open Settings, go to Control Center, and add "Scan QR Code" to your list of included controls. This is optional — the standard Camera app method above always works regardless of this setting.

Common iPhone-specific scanning issues

• Camera won't focus on the code — move slightly further away, then slowly back in; iPhone cameras autofocus better with gradual movement than a fixed close distance.
• Notification banner doesn't appear — check Settings > Camera > Scan QR Codes is enabled, and that Screen Time / restrictions aren't blocking Safari.
• Code scans but opens the wrong app — if you have a third-party app installed that's registered to handle a particular type of link (common with some payment or social apps), iOS may route the link there instead of Safari; this is expected behavior, not a problem with the code.
• Works in good light but not low light — QR scanning depends on the camera resolving contrast; try enabling the flashlight or moving to better lighting rather than getting closer.
