How to spot a fake QR code: five checks before you scan

A QR code is a disguised link: see the destination before you continue, type known destinations yourself, check for codes pasted over the real one at machines, treat urgency and shortened links as extra suspicious, and never enter login or card details on a page you did not open. A detector signal on the image is triage, never proof about where the code points.

A buyer who wants to pay cash and have a courier collect, or a paid screen while the money has not arrived: open your own banking app, let nothing be collected before the credit arrives, choose the courier yourself, pay no "insurance" through a link or gift card, and share no ID copy. Nothing was generated, only a role was forged.
