/ QR Code

Access your smartphone’s app store (Apple Store, Google Play, Windows Phone Store), search for “QR reader,” and download a QR reader app.
Once you have installed the QR reader on your smartphone, you’ll be ready to scan your first QR code. Doing this is easy. Just follow the steps below:

  1.     Open the QR code reader on your phone;
  2.     Hold your phone over the QR code so that it is clearly visible within the screen of your smartphone;
  3.     The phone automatically reads the code.

In some readers, you  will have to press a button to take a picture, but not with the camera button on your smartphone. If necessary, press the button.
Done! Your smartphone reads the code and sets a course for the intended site, although this does not happen instantly. It may take a few seconds on most devices.
