The risk in a QR code is usually not whether it scans, but what it triggers afterward. Decode the image locally first, identify whether it is a URL, Wi-Fi credential, contact card, event, payment code, or app deep link, then decide whether to open, connect, import, or pay. Chakan only decodes and warns in the browser; it does not verify merchants, tickets, or account-auth flows.

Classify the QR action before you act
A QR code can point to far more than a web page. It may carry Wi-Fi credentials, contact details, an event payload, a phone or SMS shortcut, a payment action, or an app deep link. A useful inspection workflow starts by classifying the action type first.
- Must Do: verify domains, paths, and suspicious query parameters on URL QR codes.
- Must Do: treat Wi-Fi, payment, and app-link QR codes as action-triggering inputs, not passive images.
- Must Do: inspect the payload locally before paying, connecting, importing, or sharing.
Common lookup scenarios
Inspect a QR destination before opening a browser
Check whether a public Wi-Fi QR exposes a reusable password
Review a contact QR before importing it into your address book
Check if a screenshot contains a payment QR, ticket link, or app deep link
Inspect calendar event QR codes for time, place, and external links
Clean visible screenshot privacy before sharing a QR image
Recommended workflow
- Decode the QR locally first
- If it is a URL, check the host, path, shortener behavior, and token-like parameters
- If it is Wi-Fi, contact, SMS, event, payment, or app deep link, verify whether the action should happen at all
- If the screenshot itself contains visible private details, crop or clean the image before sharing
- Keep real QR payloads, Wi-Fi passwords, contacts, payment links, and private event data out of public URLs, sitemaps, and llms.txt
