CONTACTLESS TRANSIT
SMART PASSES
& ISOLATED TICKETS.
Tap and move around town seamlessly. Keep your location history isolated, organize concert or flight tickets, and access transit gates with hardware NFC speeds.
TRANSIT MONITORING
SPANS THE WORLD.
Every metro ride, train booking, and flight reservation accumulates in centralized location databases. Your exact tracking coordinates, schedules, and patterns are cataloged and frequently shared with marketing companies.
Furthermore, carrying multiple physical cards or scanning slow barcode tickets creates massive delays at subway turnstiles. Legacy ticketing infrastructure is slow, insecure, and intrusive.
Transit Surveillance
Your physical movement histories are continuously logged and traded across municipal networks.
Bottleneck Gates
Barcode-based scanning tickets cause continuous bottlenecks at train platforms and flight check-in desks.
ISOLATED TRANSIT ALIASES
FOR ABSOLUTE PRIVACY.
UIID solves movement tracking by introducing ephemeral, travel-specific Aliases. Tap through turnstiles using high-speed NFC, leaving zero persistent profiles behind.
Hardware NFC Gate Tap-In
Communicate directly with high-frequency transit readers, verifying ticket ownership in milliseconds.
Dynamic Ticket Isolation
Keep tickets cryptographically isolated. Ticket sellers cannot track other parts of your schedule.
FAST MOVEMENT
- ✓ Tap-and-go speed matching physical tickets
- ✓ Balance storage directly on-device
- ✓ Offline ticket validations are fully supported
- ✓ Keeps localized movement logs fully encrypted
FOUR PILLARS OF SMART TRANSIT
NFC Gate Speeds
Direct hardware channel communications allow turnstiles to verify passes in milliseconds.
Location Mask
Keeps your movement history fully isolated from public ledger records.
Offline Tickets
Store cryptographically signed transit tokens locally, valid for gate entry without cellular data.
Regional Codes
Exposes standard, universally accepted transit codes on-demand.
CONTACTLESS GATE SEQUENCE
NFC Turnstile Proximity
The passenger holds their device near the turnstile. The reader wakes the secure element over high-frequency channels.
Hardware-Backed Authentication
The local device validates the active ticket signature using the Ed25519 secure vault, confirming validity without internet requirements.
Gate Open Confirmation
The gate opens instantly, logging an isolated transaction ledger locally for active verification. The passenger completes entry.
DEVELOPER INTEGRATION
Query and verify ticket validity programmatically over localized OID4VP standard formats:
{
"id": "urn:uuid:ticket_transit_claim_9901",
"issuer": "did:uiid:metro_transit_authority",
"issuanceDate": "2026-07-26T10:00:00Z",
"credentialSubject": {
"ticket_status": "active",
"zones": ["Zone-1", "Zone-2"],
"expiry": "2026-07-26T23:59:59Z"
}
}
