QR code camera guide

The easiest QR scanner is often the one already in your phone. Built-in camera scanning is fast, trusted, and works well when the code has enough contrast, size, and lighting.

Why the camera app is usually enough

How to improve camera-based scanning

  1. Hold the phone steady and center the QR code in frame.
  2. Use enough light so the camera can focus quickly.
  3. Clean the lens if the preview looks hazy.
  4. Keep the QR code flat and avoid strong glare on glossy surfaces.
  5. Increase the displayed size if the code is on another screen.
A phone camera is forgiving, but not magical. If the QR is tiny, blurred, or low-contrast, the camera can only do so much.
