QR link guide
QR codes are convenient because they remove typing. That also makes them easy to abuse: the printed code may hide a short URL, tracking redirect, or unexpected sign-in page.
Use the QR upload button in the checker to read a QR destination and inspect the link before visiting it yourself.A QR code on a flyer, parcel, parking meter, restaurant table, or email can look official even when the destination is unknown. Checking the URL first gives you a chance to notice redirects or suspicious behavior.
A QR destination normally should not need camera, microphone, clipboard, or location access unless the purpose is obvious. Permission prompts are important context in a behavior report.
Fake payment pages and sign-in forms often depend on urgency. If a QR destination asks for credentials or card details, verify the domain manually before continuing.
Do not upload QR codes that contain private login tokens, account access links, Wi-Fi passwords, or confidential documents. The public checker is intended for public or shareable links.
