Trust report
Every defence below ships with the code — no scanner app required.
Domain-bound payload
QR encodes https://born.engineer/q/… — never a foreign shortener. The brand you read is the brand that opens.
HMAC-SHA256 signature
Tokens are server-signed with QR_SIGNING_SECRET. Edited or copy-pasted codes fail verification on scan.
Confirmation interstitial
Scanners see a verified-domain card with your profile preview before continuing to LinkedIn.
No expiry
Persistent code — revoke any time from this panel to disable instantly.
Public audit manifest
Anyone can verify bindings at /.well-known/linkedin-qr.json.
Visible tamper indicators
Guilloché border, micro-text and the printed domain reveal reprinted or sticker-overlaid cards by eye.
