Are QR codes safe? How to scan safely
A QR code can't harm your phone by itself — it's just stored data. The risk is what it links to. Scammers sometimes put codes that lead to fake login pages or sketchy downloads ('quishing'). A little care makes scanning safe.
How to scan safely
- Preview the link before opening it — Scan QR Code Master shows you the destination so you can check it first.
- Look at the domain carefully; watch for misspellings or odd endings that imitate a real brand.
- Be wary of codes stuck over the top of another (for example on a parking meter or poster) — a common tampering trick.
- Never enter passwords or payment details on a page you reached from an unexpected code.
Red flags to avoid
- A code that immediately asks you to log in, pay, or install something.
- Shortened links you can't inspect, arriving from an unknown source.
- A sticker code placed on top of official signage.
- Urgent 'act now' messaging around the code.
FAQ
- Can scanning a QR code give my phone a virus?
- Scanning alone doesn't install anything — it just reads data, usually a link. The danger is following that link to a malicious site or download, so preview the destination before you open it and don't enter sensitive details on pages you didn't expect.
- How do I check a QR code before opening it?
- Use a scanner that shows the link first. Scan QR Code Master displays the decoded content so you can read the URL and decide whether to open it, instead of jumping straight to the page.
