Use case
Move every guest from invite to host without a queue
Reception is where first impressions and security meet. Duall Master pre-registers visitors, checks them in by QR or ID, notifies hosts automatically, and keeps the front desk calm even on a busy morning — with a clean record of every arrival.
One command surface
Module-by-module rollout
Audit-friendly operations
How it plays out
The scenario, step by step on one timeline.
Each step ties to a real platform action — not a slideshow.
Invite
A host invites a guest; the guest gets a time-windowed QR pass before they arrive.
Before and after
Before Duall Master
Walk-in queues and paper sign-in books at the front desk
Hosts unaware their guest has already arrived
No reliable record of who visited, when, and for whom
Recurring contractors and deliveries handled ad hoc
After Duall Master
Shared identity, policy, and site structure
Live events with module context attached
Governed operator actions with audit history
Phased expansion without replatforming

Module combinations for this use case
This use case starts with the module that solves the clearest operational pain, then expands on the same foundation.
Module stack
One operating picture, assembled module by module.
Shared foundation
Live operations layer
Access, visitors, parking, video, intercom, and audit events resolve into the same command surface.

Scenario operating model
Visitor flow optimization needs connected site signals, not another point solution.
Tap any layer to see how it helps a buyer evaluate the platform.
Signal
Doors, visitors, cameras, intercoms, parking, and devices generate live operational signals instead of isolated alerts.
01Signal
Doors, visitors, cameras, intercoms, parking, and devices generate live operational signals instead of isolated alerts.
02Context
Each signal becomes useful because operator, person, role, site, zone, policy, and related module records are shown together.
03Action
Teams approve, deny, review, escalate, annotate, or link evidence without leaving the command surface.
04Audit
Every decision keeps the who, what, when, why, and related evidence needed for handoff, reporting, and investigation.
Buyer-facing model for phased adoption: start with the clearest pain, then add adjacent modules on the same foundation.
Deployment and trust
Typical adoption path
- 01Turn on invites and pre-registration for hosts
- 02Add QR / ID check-in and host notifications at reception
- 03Connect intercom and video for deliveries and exceptions
