Is It Safe to Scan Random QR Codes?
Direct Answer
Scanning itself is safe — the risk comes from what a malicious QR code links to, the same as clicking any unfamiliar link, so check the URL preview before tapping through, especially on QR codes in public places that could have been tampered with.
Key Facts
- ✓Your phone shows a URL preview before opening the link — always read it first
- ✓"Quishing" (QR phishing) scams have targeted parking meters, restaurant tables, and delivery notices
- ✓A QR code cannot install anything or access your phone just by being scanned — the danger is only in where the link takes you
- ✓Avoid QR codes asking you to log in or enter payment details immediately after scanning, unless you trust the source
Full Explanation
A QR code is just a container for data, usually a URL — scanning it is exactly as safe as typing that URL yourself. The real risk is social engineering: a scammer places a fake sticker over a real QR code, or emails or texts one claiming to be from a bank or delivery company. Treat an unexpected QR code like an unexpected link: check the URL preview before tapping through.

How do I scan a QR code?
Open your phone's built-in Camera app, point it at the code, and tap the notification banner that appears — no separate app needed on iPhone or modern Android.
What happens if a QR code is damaged?
A QR code will usually still scan correctly even when partially damaged, thanks to built-in error correction, which tolerates anywhere from about 7% to 30% damage depending on the level used.
