## What the Face Match API does

Face Match compares two facial images and returns a similarity score indicating how likely they are to be the same person. The usual pairing is a selfie against the photograph on an identity document.

This closes the gap that document verification alone leaves open. Confirming a document is genuine proves nothing about who is holding it, and the face comparison is what ties the document to the person in front of you.

## Where teams use the Face Match API

1.  Matching a selfie to an Aadhaar or PAN photograph
    
2.  Confirming identity in remote onboarding
    
3.  Detecting applications using someone else's documents
    
4.  Re-verifying an existing customer before a sensitive action
    

## Frequently Asked Questions (FAQs)

What score should I accept?

That is a policy decision balancing false accepts against friction. Higher thresholds are appropriate for higher-value actions; set it deliberately rather than taking a default.

Does it stop someone using a photo of a photo?

Not by itself. Pair it with Face Liveness, which detects whether a real person is present.

How much do photo age and quality matter?

Both matter. Document photographs are often years old and poorly printed, so expect lower scores against a current selfie and calibrate accordingly.
