Enrollment Channels

Biometric Platform for ID Issuance supports three enrollment channel tiers. Each targets a different operational context — from staffed ID issuance centres through field enrollment kits to remote digital onboarding — all served by a shared ABIS backend.

Channel 1 — Stationary Enrollment Station​

Form factor: Windows or Android workstation, operator-assisted
Connectivity: Always online (central or regional network)

The standard deployment for national ID, passport, and civil registration programmes. An enrollment officer guides the applicant through each capture step at a fixed station inside a government office, issuance centre, or border point.

Capture modalities supported:

  • Fingerprints — ten-print flat or rolled, slap capture
  • Face — ICAO-compliant image capture with quality assessment
  • Iris — contactless capture
  • Travel document — OCR and NFC chip reading for ICAO-compliant passports and IDs
  • Signature
  • Palmprint

Supported hardware examples:

  • Mantra MORPHS slap scanner
  • EyeCool and Mantra MatisX iris scanners
  • Eloam S500 document scanner
  • HPRT HM-A300E and PM8001 receipt printers

Security: Officers authenticate using enrolled fingerprints before each enrollment session. The system prevents self-enrollment (an officer cannot enroll their own biometrics for a different person record).

Channel 2 — Portable Enrollment Kit​

Form factor: GPS-tracked, offline-capable mobile kit
Connectivity: Operates offline; syncs when connectivity is restored

Portable kits bring enrollment capability to locations without reliable network access — rural registration drives, remote communities, consulates abroad, or emergency re-issuance operations.

Kit management capabilities:

  • Encrypted registration of each kit on the central ABIS server
  • Admin/supervisor/operator roles initialized per kit during provisioning
  • Remote kit lock — a lost or stolen kit can be locked from the central server
  • User activation and deactivation per kit
  • Certificate revocation for compromised devices
  • GPS position tracking via built-in GPS device
  • Independent device management within a kit (scanner, camera, printer)

Offline operation:

  • All captured biometric data is stored in encrypted local storage on the kit
  • No network connection required during the enrollment session
  • Data automatically synchronises to the central ABIS when connectivity is restored, or via manual export/import

Capture modalities supported: Same as stationary stations — the kit combines the same biometric scanners in a portable form factor.

ABIS Enrollment Backend​

All enrollment channels submit records to the central ABIS. The ABIS handles:

FunctionDescription
Biometric template extractionFingerprint, face, iris, and palmprint templates extracted from captured images
Quality assessmentNFIQ-based fingerprint quality; ICAO-compliant facial image quality; ISO/ICAO compliance checks for travel documents
Deduplication1:N search across the full population database to detect duplicate records before committing the enrollment
Identity lifecycle managementApplicant record creation, update, history tracking, and hard-delete with MinIO attachment cleanup
Adjudication workflowPotential duplicates and exception cases routed to a supervisor workstation with split-screen face and fingerprint comparison tools
Export/ImportNIST EBTS 11.0, DoD 4.1, Interpol 6.0, and NIST ITL 2015 format support for cross-system data exchange
