# QRing Check

> QRing Check is a free web app that checks whether a QR code is safe before you open it. Scan it with the camera or upload a photo; the code is decoded on the device, links are followed server-side (never opened on the user's phone) and the result is a verdict — green (no known risks), grey (incomplete check: no risk found, but some checks couldn't be done), yellow (caution) or red (dangerous) — with the reasons and a list of what could and couldn't be checked. No app, no account, nothing stored.

What it checks:

- Real destination: follows HTTP redirects, short links (bit.ly, dynamic QR services), meta-refresh and simple JavaScript redirects, up to 8 steps.
- Fake sites: lookalike domains (paypa1, homoglyphs from Cyrillic/Greek, punycode), brand names used on non-official domains, the "@" trick that hides the real host, raw or obfuscated IP addresses.
- Risky requests: pages asking for passwords, card or bank details or verification codes, flagged more strongly on lookalike or brand-new domains; app downloads (APK, EXE, DMG, configuration profiles), including downloads started automatically by the page; links that open external apps.
- Domain age via RDAP (only the domain name is sent), abused TLDs, free hosting platforms, HTTPS and certificate validity, unusual ports.
- Non-link QR codes, analyzed entirely in the browser: Wi-Fi (open/WEP networks), phone calls and SMS (premium-rate and short numbers), email, contacts, locations, SEPA/EPC payment requests, crypto payments, 2FA (otpauth) setup, app intents.
- Optional Google Web Risk lookup when the operator enables it.
- Safety of the checker itself: SSRF protection (private/internal IPs blocked at every redirect, DNS pinning), only ports 80/443, response size and time limits.
- Honest verdicts: signals are indicators, not proof; green means "no known risks", not a guarantee, and is only given when every check could be done. Invalid TLS certificates stop the check instead of being bypassed.

## How it works

1. Scan the code with your camera, upload a photo or paste the link.
2. We follow the link on our server, step by step, to its real destination — your phone opens nothing.
3. You get a clear verdict — green, yellow or red — with the reasons. You decide whether to open it.

## How to avoid QR scams

- Look for stickers placed over the original code on parking meters, chargers, menus and posters.
- Be wary of codes in unexpected emails, letters or messages asking you to pay or log in.
- Never enter passwords or card details on a page opened from a QR code unless you're sure it's the official site.
- Don't install apps from a QR code — use the official app store.
