# Biometric Identity Document Verification
**Biometric Identity Document (ID) Verification** helps confirm that a visitor is using their own ID for security screening. When enabled, the system compares the visitor’s selfie to their photo ID, allowing Guest to verify the required information for screening.
{% hint style="warning" %}
Biometric ID Verification cannot be enabled in Guest sites located in Illinois and Portland, Oregon.
{% endhint %}
{% hint style="danger" %}
You need **Workplace Site Admin** permissions to modify Guest Types.
{% endhint %}
***

## Additional verification for unsupervised sign-ins
When a visitor signs in from a mobile device or registers for an event, Biometric ID Verification requires them to complete a liveness check. The purpose of this check is to increase confidence that the selfie is of a person who is physically present and to help prevent impersonation.
{% hint style="danger" %}
Visitors must use a camera-enabled device and grant browser camera access to complete Biometric ID Verification.
{% endhint %}

## Review Biometric ID Verification results
{% hint style="danger" %}
You need at least **Workplace Site Viewer** permissions to review Biometric ID Verification results.
{% endhint %}
If a visitor fails Biometric ID Verification, a user must resolve the issue in Command. Staff have five hours to address kiosk and mobile sign-in issues and can resolve event registration issues until the event ends.
Manually dismissing Biometric ID Verification issues allows Guest to continue with the security screening.
#### Face comparison
Face comparison evaluates whether a visitor’s selfie matches their photo ID and flags any issues for review.
* **Visitor did not pass face comparison:** Guest requires a Workplace user to review any instance where a visitor fails the face comparison during Biometric ID Verification.
* **Face comparison could not be completed:** Sometimes a face comparison cannot be completed (for example, if the ID fails to scan or the ID headshot is low quality). In these cases, Guest indicates that a resemblance check was not performed.
#### Liveness check
If a visitor fails the liveness check, Guest displays the photo captured during the check. Staff should verify that this photo matches the visitor’s face.
#### Deny Entry
Staff can take the following actions when a visitor fails Biometric ID Verification:
* **Deny entry:** If staff confirm that a visitor attempted to misrepresent their identity, they can select **Deny Entry**, which sends notifications to [relevant contacts](/guest/configuration/guest-security-screening/security-screening-settings.md#staff-notifications).
* **Override denial:** After a visitor is denied entry for failing Biometric ID Verification, a Workplace user can choose to allow entry from Command.

## Data retention
The face data used for Biometric ID Verification is deleted immediately after the check.
By default, images of IDs are deleted for approved visitors after all security screening issues are resolved. ID images can be saved after sign-in if **Save Photo ID in Records** is enabled in Command.
The system sends a PDF record of the issue to all [staff notification contacts](/guest/configuration/guest-security-screening/security-screening-settings.md#staff-notifications) if Biometric ID Verification denies a visitor entry. This record is available on Command for the shorter duration of [Retention of Saved Identification Info](/guest/configuration/guest-security-screening/security-screening-settings.md#retention-of-saved-identification-info) and [Retention of Visit Records](/guest/configuration/manage-data-retention-in-guest.md).

## FAQ
Which identity documents are supported for Biometric ID Verification?
* US state-issued ID cards
* US driver’s licenses
* Mexican Consular cards
* US passport books
* US green cards
* US work permits
* Nexus cards
Is Biometric ID Verification supported for Approved List applications?
No, Biometric ID Verification is not currently supported for Approved List applications.
Can a visitor skip Biometric ID Verification when signing in from a mobile device?
No. If a Guest Type has Biometric ID Verification enabled, visitors signing in from a mobile device or registering for an event must complete the liveness check and **cannot skip it**.
How can I enable Biometric ID Verification for kiosk sign-in only, without applying it to mobile sign-in or event registration?
Use Guest Type Visibility Controls to configure where each Guest Type appears. Select which Guest Types are available for kiosk sign-ins and which are supported for mobile sign-in and Guest Events.
How do pinned steps affect Biometric ID Verification?
For Guest Types with Biometric ID Verification enabled:
1. A face comparison will always be run.
2. If the security screening step is pinned, Guest can retain a visitor's ID image for 90 days, after which this step must be completed again. The security screen will only automatically reuse a previous ID scan for sign-ins on the kiosk. This information is retained only if the visitor opts in during the initial scan.
3. If the badge photo step is pinned, Guest can recall a visitor's selfie on kiosk sign-ins only. Signing in from a mobile device or registering for a event will always require a liveness check.
