Automated Document Verification
Authenticate Identity Documents in Seconds.
id3's document verification technology reads, extracts and authenticates identity documents — passports, ID cards, driver's licences, visas — using MRZ parsing, OCR, barcode decoding and AI-powered security element analysis. Deployable on mobile, server and embedded systems.
Explore Document SDKVerification Pipeline
Every document transaction follows the same deterministic sequence — from image capture to authenticated data output.
What It Analyzes
Every layer of the document is examined — from machine-readable data to physical security features.
MRZ Parsing
Machine-Readable Zone extraction and checksum validation — names, nationality, date of birth, expiry and document number.
OCR & Data Extraction
AI-powered optical character recognition reads VIZ fields — address, issuing authority, personal data — on any document layout.
Barcode & QR Decoding
PDF417, QR code, DataMatrix and other 1D/2D symbologies decoded and cross-validated against printed data.
Security Element Analysis
Watermarks, holograms, microtext, UV patterns and guilloche backgrounds verified against the reference document model.
Forgery & Tampering Detection
AI forensic analysis detects digital manipulation, photo substitution, field alteration and document cloning with pixel-level precision.
Face Extraction & Matching
Portrait extraction from the document for selfie cross-matching — confirming the person presenting the document is its legitimate holder.
Supported Document Types
The Document SDK covers thousands of document models from 200+ countries and territories — automatically updated via document reference database.
Choose Your Integration
Same verification engine, packaged for every deployment context — from native mobile apps to cloud REST APIs.
Document SDK
Native library with full pipeline — classification, MRZ, OCR, barcode, security analysis and forgery detection. Works fully offline.
BioSeal API
Generate and verify cryptographically signed QR codes embedded in documents — tamper-proof digital seals for any paper credential.
Custom Application
No development team? id3 builds the full document verification application — mobile, web or kiosk — around our SDK for you.
QR Code Security
Secure QR codes for physical documents — biometric data, identity fields and cryptographic proof of authenticity in a single scan.
Application Domains
Document verification is a critical step in any identity workflow where the legitimacy of a physical credential must be confirmed.
KYC & Digital Onboarding
Automated ID verification for bank account opening, insurance, telecom and fintech — compliant with AML/KYC regulations.
Border Control
Automated passport and visa reading at e-gates and border checkpoints — ICAO 9303 compliant, integrated with INTERPOL watchlists.
Access Control
Visitor management at buildings and events — verify the presented ID document on entry without manual inspection.
Education
Academic diploma and certificate authentication — detect forged credentials for universities, employers and professional bodies.
Healthcare
Patient ID and insurance card verification at point of care — prevent identity fraud in healthcare claims and prescriptions.
e-Government
Remote identity verification for digital government services — tax, benefits, voting registration and civil status procedures.
Why id3 Technologies

The Document SDK runs entirely on-device — no cloud call, no document image sent to a server. Faster, more private, compliant by design.
200+ Countries
Thousands of document models from 200+ countries and territories — continuously updated reference database with new document versions.
End-to-End Identity
Combine document verification with face recognition and liveness detection in a single SDK — document + selfie + liveness in one pipeline.
Algorithm-Level Expertise
id3 owns the full stack — OCR models, forgery detection, MRZ parser. No third-party black box, direct access to the research team.
Frequently Asked Questions
Everything you need to know about id3's document verification technology.
01 What document types are supported?
Passports (ICAO TD3), national ID cards (TD1/TD2), driver's licences, visas, residence permits, health cards, financial documents and academic credentials — thousands of models from 200+ countries and territories.
02 Does it work offline without a cloud connection?
Yes. The Document SDK runs entirely on-device — no internet connection required. Document images are never sent to a server, making it faster, more private and suitable for air-gapped deployments.
03 Can it detect forged or altered documents?
Yes. The SDK includes AI-powered forensic analysis that detects photo substitution, field alteration, digital manipulation and document cloning — at pixel level, without requiring UV or infrared hardware.
04 Can document verification be combined with face recognition?
Yes. The Document SDK extracts the portrait from the document, which can then be compared against a live selfie using the Face SDK — confirming that the person presenting the document is its legitimate holder.
05 What platforms and languages are supported?
Android, iOS, Windows, Linux and macOS — with bindings in C, C++, C#, Java, Python, Swift, Kotlin and Dart. A REST API is also available for web and server-side integration.
06 Is it compliant with KYC and AML regulations?
The Document SDK provides the technical capability required by KYC/AML workflows — automated identity verification, data extraction and forgery detection. Compliance with specific regulations (GDPR, eIDAS, 5AMLD) depends on the overall system architecture and data handling policies of the integrator.
