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.
- 01
Invite
A host invites a guest; the guest gets a time-windowed QR pass before they arrive.
- 02
Arrival
The guest checks in by QR or ID at reception; the host is notified automatically.
- 03
Inside
Access points grant only the zones the visit needs, for the time it stays valid.
- 04
Record
Every arrival, host, and departure stays searchable for security and reception.
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.

Access Control + Visitor Management + Parking · 2025
Ministry of National Defense
When one of Vietnam’s most security-critical institutions needed access control at national scale, it chose Duall Master — deployed across 15 military service branches under Project 06 (Đề án 06), unifying people, vehicles, and visitors on a single platform. Personnel are recognized by face, fingerprint, or card; vehicles by licence plate; visitors by chip-embedded citizen ID — every entry tied to a verified identity.
Access Control + Parking + Video Management · 2026
DHG Pharma
DHG Pharma runs access control, vehicle entry, and CCTV across four manufacturing sites on Duall Master — people enter by face, vehicles by licence plate and RFID, and the gate opens only when both the driver’s face and the vehicle’s plate match.
Access Control + Visitor Management + Time Attendance · 2026
TIL International Port
A busy international container port never really closes — workers, drivers, and visitors move through its gates around the clock. At TIL’s Hải Phòng terminal, Duall Master keeps that flow secure and accountable: staff enter by face or card, visitors are managed at the gate, and the same recognized entry becomes the attendance record.
Scenario operating model
Visitor flow optimization needs connected site signals, not another point solution.
Modules in play
- 01
Signal
Doors, visitors, cameras, intercoms, and parking generate live signals — not isolated alerts.
- 02
Context
Identity, policy, site, zone, and related module records attach to every signal.
- 03
Action
Operators approve, deny, review, or escalate inside one governed workspace.
- 04
Audit
Every decision keeps the who, what, when, and evidence — ready for review.
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
