You could be directed to visit a fraudulent website where you disclose personal or financial information, be exposed to inappropriate material or pick up a virus.
Use QR codes safely
- Ensure that any QR code reader app that you download is from a reputable source.
- Where possible, and especially in public places, check for visual indications that a QR code has not been tampered with (for example with an oversticker).
- Never enter personal or financial information on a website to which you have been directed from a QR code.
- If downloading security software for your smartphone or tablet, choose one which has a built-in QR code scanner.
Some commonly-available QR code readers include the ability to check the authenticity and safety of destination websites.
