Go to Google Play and search for QR Code Reader and you get over 200 results. Which one works well and does the job? I have tried numerous QR Code Readers and this one delivers for speed, accuracy and ease of use. The app is made by Scan and has over 50m downloads.
HOW THE APP WORKS
To scan a QR code or barcode 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. The app will automatically recognize any 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.
