Capabilities
What Duall Master does for Visitor Management
This module is designed as a command workflow, not a static admin screen.
QR-pass pre-registration, approval, and self check-in
Temporary access tied to zones, hosts, and visit windows
Watchlist and blocklist screening against arrivals and active visits
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.

Signal
Visitor Management events enter the same realtime operating timeline as access, visitor, video, parking, and audit activity.
Context
Operators see identity, policy, site, zone, device, and linked module records before acting.
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.

BD8500-FR
Countertop biometric station — dual-HDR face and fingerprint with liveness detection, RF card, and an 11.6" touchscreen for reception, attendance, and guest check-in.

DQ-101
Desktop citizen-ID (CCCD) reader — verifies QR, NFC, and chip data in under 3 seconds, on Windows and Linux.

DQ-Cube
1D/2D barcode + QR reader with optional RFID/NFC — built for ticketing and high-throughput lanes.

DQ-Mini+
Outdoor all-in-one terminal — reads RF card, QR, and NFC mobile ID, and controls the door.

iTOUCH 30A
Android smart terminal with dual touch screens — card and mobile QR for staffed or self-service access points.

iTOUCH popX
Wall-mount access terminal — HF/RF card, NFC phone via HCE app, and static or dynamic QR.

DE-960
Wide-card reader for access, attendance, e-payment, and parking — broad card support with Wiegand and serial output.
Field references
Previous deployments related to Visitor Management
Customer deployments delivering capabilities now packaged as Duall Master — across hospitals, universities, offices, hotels, and event venues.
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 + 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.
- 01
Invite and approve visitors before arrival
- 02
Check in by QR or chip citizen ID (CCCD), with identity and purpose captured
- 03
Notify the host on arrival and issue temporary access for approved zones and time windows
- 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.
