How to Scan a QR Code — Including the Ones You Cannot Point a Camera At

The short version: open the camera app, point it at the code, tap the notification that appears. No app to install, no button to find. That has been true on iPhone since 2017 and on essentially every Android phone since.

So rather than pad that out, here is the same answer per platform, followed by the four situations where people actually get stuck.

iPhone and iPad

• Camera app. Open it, point, and a banner appears with the destination. Tap it. You do not need to take the photo.
• Control Centre. There is a Code Scanner tile you can add — useful because it opens straight into scanning without the camera's other modes.
• From a photo or screenshot. Open the image in Photos and tap the code — iOS detects it in still images too. This is the trick most people do not know, and it solves half the awkward cases below.

Android

• Camera app. On most phones, point and a link chip appears. Some manufacturers hide it behind a mode or a lens button.
• Google Lens. Available in the camera, in Search, and in the Photos app. The most reliable route when the built-in camera is being stubborn.
• Quick Settings. Many phones have a scanner tile in the pull-down panel.
• From an image. Open it in Google Photos and use Lens on it.

If nothing happens at all, check that the camera has permission and — on older Android — that scanning is not switched off in camera settings.

The four cases people get stuck on

1. The code is on the screen you are holding

You cannot point a phone's camera at its own display. This comes up constantly with codes in emails, in an Instagram story, or in a message someone sent you.

Options, in order of ease: long-press the image — Android often offers "Search with Lens"; take a screenshot and open it in Photos or Lens, which works everywhere; or, if the code is in a web page, long-press it and copy the link directly, since the code is only a link in the first place.

2. The code is on a computer screen

This is the easy direction and works fine — a phone reads a code off a monitor without trouble. Two caveats: raise the screen brightness, and avoid scaling the image so small that the modules blur.

3. You have the image but no phone

On a desktop you can use a browser extension or an online decoder that accepts an uploaded image. Be careful what you upload — a code from a document may contain something you would rather not paste into a stranger's website. If it is a link, a decoder simply hands you the URL, which you could also get by long-pressing the original.

4. It scans, but you should not tap it

The scan is not the risk; the destination is. Before tapping, read the domain in the preview banner, not the words around the code. Malicious codes are usually stickers placed over legitimate ones — on parking meters, restaurant tables, delivery notices — and the giveaway is a domain that does not match the business, or a login page arriving unprompted.

Two habits worth having: never enter payment details on a page you reached by scanning something in the street, and treat "your parcel is held, pay the fee" codes as fraud by default.

When the code simply will not read

Almost always the code, not the phone. Move to arm's length and back — some cameras cannot focus very close. Tilt away from ceiling lights if the surface is glossy. If it still fails on two different phones, the code itself is at fault: too small for the distance, too little contrast, no white border, or a logo covering more than the error correction can carry.

To be clear about our part in this

We do not make a scanner app, and you do not need one. Every phone already has a scanner in the camera, and an extra app adds a step and an advertisement. Enqre is on the other side of the interaction — we generate the codes and the redirect behind them. If a page recommends downloading a scanner, ask what it is for.

Quick answers

• Do I need an app to scan a QR code? No. The camera app does it on iPhone and on nearly all Android phones.
• How do I scan a code that is already a photo? Open the image in Photos (iOS) or Google Lens (Android) and tap the code.
• How do I scan a code shown on my own phone? Long-press it for Lens, or screenshot it and open the screenshot.
• Can I scan from a laptop screen? Yes. Turn the brightness up and keep the code reasonably large.
• Why does nothing happen when I point the camera? Check camera permission, then check the code: distance, focus, glare, contrast.
• Is scanning a QR code dangerous? Scanning is not. Tapping through is where care is needed — read the domain first.
