No need to take a photo or press a "scan" button.When scanning a QR code, if the code contains a website URL, you'll automatically be taken to the site. If the code just contains text, you'll immediately see it. For other formats (such as phone numbers, email addresses, or contact info), you will be prompted to take the appropriate action.Scan now reads regular barcodes (UPC, EAN, and ISBN) and gathers information about the products you scan, allowing you to research and find places to purchase the products you love.
