300M+ people worldwide hold dual or multiple citizenships. Millions more have renewed passports, expired documents, and national IDs from different countries. Every platform that verifies identity creates a new "person" per document — fragmenting the user's digital life across incompatible silos.
You verified with passport A. It expires or gets lost. You have passport B (different country). The bank can't link you — you're locked out of your own accounts.
New document? New verification. New country, new passport, start from scratch. €1,500–3,000 per KYC onboarding — multiplied by every document change.
Criminals exploit multiple passports to open accounts under different "identities." Banks can't link them. Unified Digital Identity solves this — for honest users and for compliance.
Turkish passport + German passport + expired Turkish passport + national ID card — all cryptographically linked to one persistent identity. Add documents over time. Remove revoked ones.
If one passport expires or is lost, the unified identity persists through the remaining linked documents. No lockout. No re-verification. Continuity by design.
Linking is voluntary and user-initiated. The user scans each document via the IdentiGate app and confirms the link. Nobody can link documents without the user's explicit consent and biometric confirmation.
Your platform receives a single, stable pseudonymous identifier — not the underlying passport numbers. The user is always the same "person" regardless of which document they used to authenticate. GDPR-aligned pseudonymization by design.
Biometric face match across all linked documents ensures the same physical person. This prevents multi-accounting, identity fragmentation exploits, and AML evasion through document rotation.
Link documents from any country — via NFC chip (179 ICAO 9303 countries) or document + face match (everywhere else). Turkish + German + Moroccan + Brazilian — all in one identity. No limit on number of linked documents.
User verifies their first document via the IdentiGate app — via NFC chip (for passports and ID cards from 179 ICAO 9303 countries) or via document capture + face match (everywhere else). This becomes the primary anchor of the unified identity.
User scans additional passports or ID cards. For each, IdentiGate verifies the document (NFC or document + face route) and runs a biometric face match against the primary identity. Same face = same person = linked.
A single, stable pseudonymous identifier is generated — cryptographically bound to all linked documents. Your platform always sees the same user, regardless of which document they authenticate with.
Passport expires? Scan the new one and link it. Lost a document? The identity persists through the others. Add or remove documents over time — the Unified Digital Identity stays stable.
A dual citizen verifies with their Turkish passport at a bank. Two years later, the passport expires. They try to access their account with their German passport. The bank's system sees a "new person" — account locked, re-verification required, weeks of back-and-forth.
With Unified Digital Identity, both passports are linked to the same identity. The bank always sees the same identifier. Passport change = seamless. No lockout. No re-KYC.
Criminals exploit multiple passports to open separate accounts under different "identities" — fragmenting their financial footprint to evade AML detection. Banks can't link accounts opened under different documents.
Unified Digital Identity solves both sides: honest dual citizens get seamless access, while platforms can detect that the same biometric person is trying to create multiple "identities." One person = one Unified Digital Identity. Period.
Seamless access across all documents. No lockout. No repeated KYC. Identity follows the person, not the paper.
Detect multi-accounting. Link fragmented profiles. Prevent AML evasion through document rotation. One biometric person = one identity = one risk profile.
Your platform receives one Unified Digital Identity per user — always the same, regardless of which document they authenticate with. Your database stays clean.
Same biometric person tries to create a second account with a different passport? Detected automatically. One person = one Unified Digital Identity. Multi-accounting blocked.
Passport renewal or document change no longer triggers full re-verification. The Unified Digital Identity persists. Your compliance team saves €1,500+ per affected user.
Customers with dual citizenship, expats, digital nomads — all need seamless account access regardless of which document they use. Unified Digital Identity prevents lockout and reduces re-KYC.
A Turkish driver with dual DE citizenship uses different passports at different border crossings. Unified Digital Identity ensures the eCMR system always sees the same verified driver.
Prevent multi-accounting where one person creates multiple gaming accounts with different passports. Unified Digital Identity ensures: one biometric person = one account. Self-exclusion lists work across all documents.
Every document link requires the user's active consent and biometric confirmation. No one — including IdentiGate — can link documents without the user.
Your platform receives a Unified Digital Identity — not passport numbers. The mapping between documents and Unified Digital Identity is never exposed to the relying party.
For regulated entities, Unified Digital Identity can surface a "same person" flag when duplicate detection is enabled — helping compliance teams consolidate risk profiles.
Unified Digital Identity pricing depends on your user base — how many customers hold multiple documents, how often documents change, and your compliance deduplication needs. We scope pricing case by case.
