  1. Open the QR Code reader on your phone.

  2. Hold your device over a QR Code so that it’s clearly visible within your smartphone’s screen.

    Two things can happen when you correctly hold your smartphone over a QR Code.

    1. The phone automatically scans the code.

    2. On some readers, you have to press a button to snap a picture, not unlike the button on your smartphone camera.

  3. If necessary, press the button.

    Presto! Your smartphone reads the code and navigates to the intended destination, which doesn’t happen instantly. It may take a few seconds on most devices.
