FAQ

What is the best format for a printed WiFi QR?

Use the standard WIFI: T:WPA;S:NetworkName;P:Password;; payload for static guest WiFi. For rotating passwords or captive portals, use a dynamic QrLitz slug to a landing page instead.

How big should a WiFi QR be on a wall sign?

At least 3×3 cm for lobby signs guests scan from 1–2 meters. Higher contrast and larger quiet zone than menu QRs.

iPhone vs Android WiFi QR — any difference?

Both read standard WiFi QR payloads. Always test on one device of each type before printing lobby signage.

Should hotels use static or dynamic WiFi QRs?

Static for fixed guest SSID/password. Dynamic when you change passwords weekly, use captive portal vendors, or need to swap portal URLs without reprinting room cards.
