Common Questions
Is a free QR code scanner app for Android safe to use, and how can I tell?

Yes, safety depends on permissions and policy. Check reviews and the privacy policy before installing.
Do free QR scanners require camera access to work, and will they read every type of code?

They usually use the camera and handle most common codes, but verify supported formats in the app listing.
Can I use a free QR scanner offline, without sending data to a server?
