To scan a QR code or barcode simply open the app, point the camera at the code, and youre done! There is no need to take a photo or press a button. The app will automatically recognize any code.
When scanning a QR code, if the code contains a website URL, you will automatically be taken to the site. If the code just contains the text, youll immediately see it. For other formats such as phone numbers, email addresses, or contact info, you will be prompted to take the appropriate action.
