Read article →Frequently asked questions
Does the app work without an internet connection?+
Scanning and reading the content of a QR code works without internet. You'll only need a connection if the code itself points to a website you then choose to open.
Can I create my own QR codes, not just scan them?+
Yes, the app includes a built-in QR code generator for turning a link, piece of text, Wi-Fi details or a contact card into a scannable QR code.
Does it scan regular barcodes too, or only QR codes?+
The app supports common barcode formats in addition to QR codes, so it works for scanning product barcodes as well.
Is it safe to scan QR codes with this app?+
The app shows you what a QR code contains before taking any action, such as opening a link, so you can check it looks legitimate before proceeding — a safer habit than apps that open links automatically.
Is the app free to use?+
Yes, QR Code Scanner is free to download and use from the Google Play Store.
