Success stories from real site operations.
Explore reference deployments that show how access, visitors, attendance, lifts, and operating records come together around practical site workflows.
Ministry of Information and Communications — Vietnam
The Ministry of Information and Communications has run access control and staff attendance on Duall Master at its Vietnam headquarters since 2019 — 12 doors secured with QR and Face ID, where the same recognized entry also records attendance.
DHG Pharma (Dược Hậu Giang)
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.
TIL International Port — Hải Phòng
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.
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.
Children's Hospital 1 — Ho Chi Minh City
Children's Hospital 1, one of Ho Chi Minh City's largest paediatric hospitals, runs access control, visitor management, and staff attendance for roughly 10,000 people on one on-premise Duall Master platform — 84 doors and 14 lifts governed together and integrated with the hospital's management system.
AhaSlides
A young, fast-moving software startup runs office access control and attendance on Duall Master’s cloud service — live fast with no on-site servers, entry by Face ID, QR, or phone, and most day-to-day tasks handled right from the mobile app.
D'home Sapa Hotel
D'home Sapa, a hotel group whose guests mostly book online, uses Duall Master to make guest handling effortless — each booking gets a QR code or Face ID, so guests check themselves in without a receptionist and without physical room keys to manage.
STI Office Indonesia
STI runs office access control, lift access, and staff attendance on Duall Master at its site in Indonesia — the same platform proven in Vietnam, working across a building where one credential opens doors, calls the right lifts, and records attendance.
