QR Code Scanner
Nothing opens by itself. You see where the code goes first, in big letters. The camera image stays on this device.
You can also paste a copied image with Ctrl+V (⌘V).
Fit the QR code inside the square.
The camera only turns on after you tap, and the image is read on this device. Nothing is sent anywhere.
Questions people ask
Can QR codes be used for scams?
Yes. "Quishing" sends people to fake pages that ask for logins or payment. That is why this scanner never opens a link by itself and shows the real domain and warning signs first. If a code you found in public asks you to log in or pay, do not open it.
Which warning signs does it check?
Unencrypted http, link shorteners, IP addresses instead of a domain, punycode (xn--) or %-encoded domains that can disguise letters, an @ that hides the real domain, addresses dressed up to look like another site, words like login, verify or payment, and premium-rate numbers. No warning does not mean a link is safe.
Where does the camera image go?
Nowhere. The camera feed and uploaded images are read inside your browser and are not stored or sent.
The camera does not start.
Allow camera access for this site (the lock icon next to the address bar), or upload a photo or screenshot instead.
