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 Pseudo-ID 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.
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 passports from any ICAO 9303-compliant country. Turkish + German + Moroccan + Brazilian — all in one identity. No limit on number of linked documents.
User verifies their first passport via the IdentiGate app — NFC scan, face match, split-key creation. This becomes the primary anchor of the unified identity.
User scans additional passports or ID cards. For each, IdentiGate reads the NFC chip 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 Pseudo-ID 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 Pseudo-ID, both passports are linked to the same identity. The bank always sees the same Pseudo-ID. 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 Pseudo-ID 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 Pseudo-ID. 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 Pseudo-ID 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 Pseudo-ID. Multi-accounting blocked.
Passport renewal or document change no longer triggers full re-verification. The Pseudo-ID 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. Pseudo-ID prevents lockout and reduces re-KYC.
A Turkish driver with dual DE citizenship uses different passports at different border crossings. Pseudo-ID ensures the eCMR system always sees the same verified driver.
Prevent multi-accounting where one person creates multiple gaming accounts with different passports. Pseudo-ID 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 Pseudo-ID — not passport numbers. The mapping between documents and Pseudo-ID is never exposed to the relying party.
For regulated entities, Pseudo-ID can surface a "same person" flag when duplicate detection is enabled — helping compliance teams consolidate risk profiles.
