Scanner QR code reader is extremely easy to use; simply point to QR or barcode you want to scan and app will automatically detect and scan it. No need to press any buttons, take photos or adjust zoom. :) But, if I have QR code from gallery how can I scan? Don't worry, from now you can scan from gallery. ;)

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 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.

How to Use:
-Simply point to QR or barcode you want to scan and app will automatically detect and scan it
