Frequently Asked Questions

Do the generated QR codes ever expire?

No. DocScalar generates standard static QR codes where payload information is encoded directly into the 2D matrix pattern; they remain permanently functional without expiration or redirects.

Is my encoded payload data (URLs, WiFi passwords, contact vCards) private?

Yes. Payload encoding is computed in transient memory buffers over TLS 1.3 with zero telemetry tracking, payload caching, or server persistence on disk.

What data types and error correction levels are supported by the QR generator?

DocScalar supports URLs, plain text, vCard contacts, email templates, and WiFi credentials, with selectable error correction levels (L, M, Q, H up to 30% recovery) for damaged surfaces.

Can I download the QR code in scalable vector format?

Yes. You can export as infinite resolution SVG for professional print branding or crisp high DPI PNGs optimized for digital displays and social media graphics.
