Use cases

One verification engine, many front lines.

OneTap suits any situation where you must trust — not just read — a person’s government document, face to face. The strongest fit is wherever a forged ID causes real financial or legal exposure.

KYC & onboarding

Banks, fintech, crypto, bureaux de change

In-person identity proofing with genuine-document assurance — beyond a photo scan.

Access & security

Venues, events, buildings, visitor management

Fast one-tap entry with a real authenticity check on the presented ID.

Hospitality & rental

Hotels, short-lets, vehicle & equipment hire

Confirm a guest or renter’s ID is genuine and unexpired — legally required across much of the EU.

Regulated retail

Alcohol, tobacco / vape, cannabis, gaming

Prove legal age and catch forged IDs — one policy layered on real verification.

Assisted public services

Front desks, agencies, gov-adjacent checks

Staff-assisted authenticity checks on national IDs and passports at the counter.

Marketplaces & gig

Driver / host onboarding, P2P handovers

Confirm a counterparty’s document is real, face to face.

What a check looks like

Genuine, unexpired, eligible — in seconds.

The same flow whether it’s a passport at a hotel desk or an eID at a bank branch.

01

Tap or scan

The customer taps their eID/passport to the phone, or the staff member scans the document barcode. No account, no connection required.

02

Read securely

OneTap opens an encrypted session with the chip and reads the signed data — or decodes the signed barcode.

03

Verify authenticity

The document’s cryptographic signatures are checked against the issuing authority. Tampered or fabricated documents fail here.

04

Apply your policy

Age, expiry and jurisdiction rules run on the verified data, returning a clear pass / review result your staff can act on.

The differentiator

Why authenticity beats a photo scan.

A camera-only “ID scanner” can be fooled by a good print or a photo of a photo. Because OneTap verifies the government’s own digital signature on the chip or barcode, a forged or altered document is caught — not waved through. That difference matters most where you are liable for getting it wrong.

  • Catch forged and altered documents, not just expired ones
  • Reduce liability with a cryptographic, auditable result
  • Works across EU eID cards, passports and US driver licenses
  • Fast enough for a queue; private enough for regulators
