Questions
How do I scan a QR code from an image?
Press Choose image, drop the picture on the scanner or paste it with Ctrl+V. A screenshot works too.
Is it safe to open a link from a QR code?
Check the full address first. The scanner shows the whole link and never opens it on its own, so open it only if you recognize the site.
How do I join a Wi-Fi network from a QR code?
Scan the code to see the network name, password and security type. Copy the password and enter it in your Wi-Fi settings.
Why won't my QR code scan?
Hold the camera steady, let the code fill about half of the frame and avoid glare. Blurry, very small or damaged codes may not read.
