Door code, Wi-Fi, booking refs, address, phone, check-in time — the things you fumble for at a front desk. Type them once, keep them on this device, tap to copy, and blow up the door code at night.
Type your trip details below, or load a sample card to see how it works. Everything you enter stays on this device.
About your data: this card is a static page with no backend. It stores your details in this browser's localStorage and makes zero third-party requests — no analytics, no trackers, no fonts or CDN. Clearing your browser data (or tapping Clear) deletes the card. Sharing a link or exporting JSON is the only way your details leave this device, and both are actions you trigger yourself. The door-code big view is just high-contrast full-screen text to read in a dark hallway — it does not change your screen brightness.
