How do I interpret the Facial Comparison?

This section will be visible on the Transaction Details page if your organisation's capture process includes one or more facial biometric options.  The purpose of this check is to confirm that the person presenting the ID documentation is the rightful owner of that documentation, and also that they are a live person (i.e. not a malicious bot).  

The images on the right provide an example of a live selfie process checked against a fake ID.  The number of photos will vary based on your organisation’s specifications. 

Comparison with ID check

If an ID document supplied contains a photo (such as passport or drivers license) then our system will compare its photo with the Centre facing biometric image.  The percentage value displayed below the Centre facing image is the confidence level for a match with the ID photo.  This value should be higher than 70% to pass.

Liveness check

The remaining biometric images are also compared with the Centre facing image. The percentage value displayed below each of them is the confidence level for a match with the Centre facing image.

When Facial Comparison check is not passed

The most common reasons why the facial imagery may not match include:

  • Wearing glasses or other headwear 

  • Poor lighting and/or;

  • Outdated photo on their ID

If a Facial Comparison check has not passed but you believe the biometrics to be valid, remember to consider the results of the other checks as well.  Always review a transaction against your organisation's risk appetite, and only once you have done this should you consider forcing a Match on the basis of the facial comparison.
