Department of Immigration
Biometric verification engine for Bhutan's identity and border infrastructure, plus on-the-ground installation and configuration of the automated e-Gates at the Phuentsholing pedestrian terminal — Bhutan's busiest land border crossing.
The Challenge
The Phuentsholing pedestrian terminal is Bhutan's busiest land border with India — roughly 15,000 travellers a day cross between Phuentsholing and Jaigaon, with sharp spikes during school holidays, pilgrimage seasons, and shopping periods around festival dates. Until early 2025, every entry and exit was processed by an immigration officer typing the traveller's details into the system by hand. Each clearance took three to five minutes; queues at peak times were the predictable result.
The Department of Immigration needed two things at once: a self-service clearance flow at Phuentsholing that could move travellers through in under a minute, and a sovereign biometric verification capability — one that ran on Bhutanese infrastructure with zero external API calls, so citizen and visitor identity data never left the country.
The Approach
We delivered the project in two tightly-coupled layers.
The first is the biometric verification engine — a production-grade face-matching system with liveness detection and document OCR for Bhutanese travel documents. It runs entirely on-premise: no part of a verification leaves the department's infrastructure. For Bhutanese citizens, the engine queries biometric records held by the Department of Civil Registration and Census (DCRC) — the national source of truth — rather than duplicating that data. Foreign visitors are enrolled at first entry and matched against the local enrolment set on subsequent crossings. The same engine is reused by the Immigration Portal and officer-facing tools, so identity verification works consistently across the department's stack.
The second layer is the on-the-ground installation and configuration of the eGates at the Phuentsholing pedestrian terminal. The clearance path is deliberately stripped down: no document scan, no fingerprint, no manual interaction. A traveller stands at the kiosk, the camera captures a live face image, and the engine runs the comparison — against the DCRC record for Bhutanese citizens or the enrolment record for foreigners. When the match passes, the gate opens. Only edge cases route to an officer.
The Outcome
The Phuentsholing eGates were inaugurated on 21 February 2025 by Home Minister Tshering. The operational shift was immediate. Manual clearance had taken three to five minutes per traveller; the kiosks complete a face match in roughly three to five seconds. At the busiest land crossing in the country, that's the difference between a queue that snakes out into the terminal and a queue that doesn't form at all.
Beyond Phuentsholing, the biometric engine continues to power DoI's identity workflows nationally, with consistent accuracy above 99% on Bhutanese travel documents. The same engine is positioned to underpin further automated border deployments as the department expands self-service clearance to other crossings.
