Security Audit tips

🛡️

QR phishing is on the rise — malicious QR codes posted in public places. Use this tool to see the destination URL before opening it on your phone.

⚠️

A safe-looking sticker can hide a redirect URL. Always check the decoded text against the expected destination before opening links.

💡

Restaurants sometimes have fake QR codes stuck over real ones, pointing to fraudulent payment pages. The decoded URL exposes this immediately.

🔒

Even decoded text is just text — clicking "Open link" navigates, but the decoder itself never auto-opens anything.
