The guard taps. Your phone rings.
Someone arrives for your flat. The request takes over your screen — name, photo, purpose, a 30-second ring. No phone hunt, no shouting up the stairwell.
One tap, decided.
Approve or decline from the sofa, the office, the train. The guard sees your answer instantly over WebSocket — the boom barrier's story ends the way you chose.
The register fills itself.
Every decision is logged with who and when. No diary, no scribbles — a clean record your committee can actually read, months later, in seconds.
