# How it works

## Modern passports and ID cards contain a secure chip that can be read via NFC on a mobile device. The chip holds identity data that is digitally signed by the issuing government.

## Digital wallet credentials are signed in the same way. In both cases, the signature proves the data is genuine, untampered, and issued by a trusted authority.

## Secure communication protocols further protect against cloning and replay.

## This means you are not trusting images or videos. You are trusting cryptographic proof.

## From credential to verified identity

## **Present a credential**   Scan a passport or ID card, tap to read the chip, or present a digital wallet credential.

## **Read signed data**   Identity data is read directly from the chip or wallet — exactly as issued.

## **Verify authenticity and chain of trust**   The cryptographic signature is verified against the issuer's certificate chain. Tampered, cloned, replayed, or fraudulent documents cannot pass.

## **Return verified identity evidence**   Your system receives unified and trusted identity attributes — name, date of birth, nationality, document number, and more — ready to act on.

## What you can verify

## **Passports and ID cards** **● live**   Electronic passports supported globally, covering billions of people. National ID cards in markets where they are the primary identity document. [Browse coverage](/content/coverage/index.html).

## **Digital wallets** **● coming soon**   Emerging government wallet rollouts, including EUDI and mDL. [See current EUDI wallet status](/content/eudi/index.html).

## How it reaches your users

## **Hosted flows**   A ready-made verification journey in the browser. No app installation required for most users. The fastest path to verified users with zero frontend work.

## **Native mobile SDKs**   Embed verification directly into your iOS or Android app for a fully native, on-brand experience.

## Stronger assurance when you need it

## Two layers of holder binding.

## **Face matching**   Compare a live selfie stream with the document's embedded portrait. Confirms the person presenting the credential is its rightful owner.

## **Liveness detection**   Confirms the person is physically present and not a spoof.

## You decide what happens next

## Onboard, approve, step up, or decline — your policies applied to verified identity evidence.
