Duall Master

Invite · pre-register · check-in

Every guest, from invite to sign-out — on one secure track

Pre-registration, QR passes, watchlist screening, and host notifications run on the same identity, access, and audit backbone as the rest of your site.

Operating model

Capabilities

What Duall Master does for Visitor Management

This module is designed as a command workflow, not a static admin screen.

01

QR-pass pre-registration, approval, and self check-in

02

Temporary access tied to zones, hosts, and visit windows

03

Watchlist and blocklist screening against arrivals and active visits

04

Visitor history linked to site events and audit records

Visitor journey

One visit, end to end

Guests register online or at the lobby; once the host approves, the same face or QR carries them through gates, lifts, the meeting, and back out — every step on the audit trail.

Visitor Management workflow
Duall Master Visitor Management module
1

Signal

Visitor Management events enter the same realtime operating timeline as access, visitor, video, parking, and audit activity.

2

Context

Operators see identity, policy, site, zone, device, and linked module records before acting.

3

Action

Approvals, overrides, reviews, and notes are governed by role and preserved in audit history.

Hardware

Runs on real Duali devices

Face, card, QR, and NFC terminals, door controllers, and outdoor readers — the same hardware deployed on live sites.

Previous deployments related to Visitor Management

Customer deployments delivering capabilities now packaged as Duall Master — across hospitals, universities, offices, hotels, and event venues.

Ministry of National Defense legacy case study reference

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.

TIL International Port legacy case study reference

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.

Access Control + Visitor Management + Time Attendance · 2024

Vietnam Military Medical University

A military medical university running access control, chip-ID visitor registration, and attendance for nearly 8,000 staff, students, and clinicians on one platform — face-recognition entry across the unit and citizen-ID check-in at patient reception.

Hardware context

Visitor check-in at the entrance by face & QR

Use the product UI to follow the guest reception workflow and audit trail. After registering at the counter, visitors check in at the entrance by face or QR on the Duali reader — every pass logged.

Operating workflow

From signal to context to action

A visitor management workflow should not end in an isolated log. It should move operators from live signal, to useful context, to governed action.

  1. 01

    Invite and approve visitors before arrival

  2. 02

    Check in by QR or chip citizen ID (CCCD), with identity and purpose captured

  3. 03

    Notify the host on arrival and issue temporary access for approved zones and time windows

  4. 04

    Review visitor history with related access and operator events

Built on one platform

Visitor Management runs on the same platform as every other module.

Each module works on its own — but they share one identity, events, audit, and integration layer, so they are stronger together. Exact scope is confirmed per project.

Product proof

Built for operational review, not just administration.

The module experience is designed around live status, structured records, linked context, and audit-friendly decisions.

Platform connection

Stronger because the foundation is shared

Each module uses the same identity, event, audit, integration, and deployment foundation.

Visitors use the same site, zone, and identity model as access control
Approvals and operator actions are retained in audit history
Video and intercom context can support incident review
APIs can connect tenant apps or reception workflows
