QR on a printed CV: iPhone saves the card to Apple Wallet, Android opens an adaptive portfolio. Scan-limited, so a scraper cannot mine the printed run.
OS routing picks the right destination per device. A 10-scan limit caps how far one printed batch travels: once it is used up the code stops resolving and shows the EQR limit notice instead of your contact page. Every scan that does resolve fires a webhook, and a scan-alert email tells you the CV is being read.
Free tier includes 1 standard QR code. Upgrade to the paid Eternal tier for blockchain permanence and the recovery key.
