Interactive door tag

Sticker on the front door replaces a smart doorbell. Couriers tap 'I'm here' (webhook → push). Guests enter a PIN to see the guest Wi-Fi or instructions for the key safe.

Password lockWebhooks

How it works

One QR, two audiences. Couriers see a public 'I'm at your door' button that fires a webhook to the owner's phone. Friends with the PIN unlock a private page with the guest Wi-Fi, parking note, or key-safe combination.

What you get

A doorbell-grade workflow with no wiring or hardware install.
Friends get hospitality info, strangers don't.
