How to Scan a QR Code (iPhone & Android)

Scanning a QR code takes seconds and, on most modern phones, needs no special app — just your camera. Here's how on iPhone and Android, plus what to do on older devices.

On iPhone and Android

Open the built-in Camera app and point it at the code. Hold steady for a second and a notification or banner appears — tap it to open the link or action.

If nothing happens, make sure the whole code is in frame, well-lit, and in focus. Most phones from the last several years support this natively.

Older phones and screenshots

On older Android phones, open Google Lens or a free QR scanner app. On iPhone, you can also scan a code saved in your photos using the Photos app's Live Text and Lookup.

To scan a code that's on your own screen, take a screenshot and open it in Google Lens (Android) or Photos (iPhone) to detect the code.

Step by step

  1. 1

    Open the camera

    Launch your phone's built-in Camera app.

  2. 2

    Point at the code

    Frame the whole QR code and hold steady.

  3. 3

    Tap the prompt

    A banner appears — tap it to open the link or action.

  4. 4

    Use Lens if needed

    On older phones, use Google Lens or a free scanner app.
