What is a biometric passport?

A biometric passport carries biometric information linking a person to their passport.  Biometric verification can be used at border controls and to check that the image on a passport renewal application matches the images we hold on record.

We can also use biometric information to:

• Allow automated immigration checks in the future
• Make sure British citizens can still travel to the USA visa-free
• Make sure British passport holders are not at a disadvantage as other countries switch to biometric passports.

Why biometrics?

Because of the increasing threat of identity fraud we need to strengthen security features in passports. The International Civil Aviation Organisation (ICAO), which sets international standards, chose facial recognition as the main biometric measure. Iris and fingerprint recognition are a back-up, but they are not compulsory.

How do facial biometrics work?

Facial recognition maps the various features on the face - for example, the distances between eyes, nose, mouth and ears. These measurements are digitally coded and can then be used for comparison and verification purposes. Biometric technology is perfectly safe because facial biometrics can be taken from a good quality passport photo.
