QR scan
QR Scan is the fastest and most user-friendly QR code scanner available. If your Android came with a built-in scanner, this would be it. Here is what our reviewers are saying:
“Quick and very reliable. I’d give it six stars if it were possible.”
HOW THE APP WORKS
To scan a QR code simply open the app, point the camera at the code, and you’re done! There is no need to take a photo or press a button. QR Code Reader will automatically recognize any QR code your camera is pointing at.
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.
