Do I need a scanner app?

No. Any iPhone from the last decade and almost every Android phone scans QR codes with the built-in camera — open it, point, tap the banner. Apps only add ads and tracking. If your camera truly cannot do it, Google Lens (free, already on most Androids) covers the gap.

Why won't my code scan?

Check four things in order: light (move into brightness), distance (10–20 cm, fill the frame), size (wallet-card minimum, bigger outdoors), and contrast (black on white always wins). Nine failed scans in ten come from one of these — the code itself is rarely broken.

Can I scan a QR code from a screenshot?

Yes. Open the screenshot on your screen and scan it with another phone's camera exactly like a printed code — or long-press the image on iPhone and tap the link. Google Photos Lens reads screenshots too. The code inside the picture works the same wherever it is displayed.

Can I scan a QR code from a photo in my gallery?

Yes. On iPhone, open the photo, long-press the code, and tap the link that appears. On Android, open it in Google Photos and tap the Lens button. Saved wedding codes, tickets, and wifi photos all scan straight from the gallery with no reprint.

Does scanning need internet?

The scan itself needs nothing — the phone reads the pattern offline in a fraction of a second. You only need internet when the code points at a web page, a menu, or a video. Wifi-join and saved-contact codes work fully offline, even in airplane mode.

Is scanning a QR code safe?

Mostly yes, with one habit: read the preview before you tap. Your phone shows the address first — if it looks odd, shortened beyond recognition, or nothing like what you expect, stop there. Never enter passwords or card details on a page you reached by scan unless you trust the source completely.

Common questions

Where is the scanner on iPhone?

There is no separate scanner — the normal Camera app does it. Open Camera, point at the code, and tap the yellow link banner that drops down. It works on every iPhone of the last decade with nothing to enable and no update required.

How do I scan a photo in my gallery?

Open the photo, press and hold the QR code, then tap the link shown (Open in Safari). The phone reads the pattern straight from the saved image — screenshots, tickets, and wifi photos all work with no reprint and no second device.

My iPhone won't scan — what now?

Move into better light, hold the phone 10–20 cm away, and wipe the lens on your sleeve. Then check Settings, Camera, Scan QR Codes is switched on — it ships on, but a reset can flip it. Google Lens (free) reads any stubborn code as backup.
