Every QR code inspected on your device before you open it. No cloud, no tracking, no uploads. Ever. Scan first. Open only if it is safe. Quishield inspects every QR code on your device and warns you before a malicious link can hurt you. QR phishing ("quishing") is one of the fastest growing scams: fake parking meters, restaurant menus, invoices and delivery notices that lead to credential theft pages. How it works: - Point the camera at any QR code - Quishield analyzes the link locally: lookalike domains, punycode tricks, hidden redirects in the address, IP based links, URL shorteners, suspicious top level domains and lure wording - You see a clear verdict with the reasons, and the real destination spelled out, before anything opens - Opening or copying a risky link always asks for confirmation first Private by architecture, not by promise: - 100% offline. Quishield has no server and never uploads your scans - No accounts, no ads, no analytics, no tracking - Scan history stays on your device and can be cleared at any time Quishield cannot guarantee that a link is safe; it shows you the warning signs a careful human would look for, instantly, so you can decide with open eyes.
