2. Why You MUST Stop Using SaaS QR Vendors in GDPR/CCPA Countries
Austrian DSB issued €128k fine (Feb 2026) against a restaurant chain for embedding a US SaaS QR menu service — every scan routed through Virginia servers, included visitor UTM/IP fingerprint, stored 6+ months with no processing contract. Korelyy generates QRs in the browser tab, encodes the URL directly in the image, no network round-trip. You can download 500 serial QRs as a ZIP in 3 seconds and print them via Avery label sheets locally.
