What this QR scanner does

QR Scanner & Security Guard decodes QR codes from a camera stream or uploaded image, then shows the destination before you decide what to do next. It is useful for checking printed codes, downloaded images, posters, packaging, tickets, and unknown links.

Security teams, support staff, event teams, and everyday users can use it to inspect a code before opening it. Seeing the decoded text first reduces accidental visits to suspicious or mistyped destinations.

If a QR code points to a login page, payment page, or shortened URL, verify the domain carefully before opening it.
