PARAFE

PARAFE (abbreviation of Passage Automatisé Rapide Aux Frontières Extérieures or automated fast-track crossing at external borders) is a passport verification program operated by France's Direction centrale de la police aux frontières (DCPAF; border police). PARAFE, incorporating automated self-service barriers operated by DCPAF, is located at immigration checkpoints in the arrival and departure halls at the Paris, Marseille, Nice and Lyon airports and at London St. Pancras train station, offering an alternative to using desks staffed by immigration officers. The gates use facial recognition technology to verify the user's identity against the data stored in the chip in their biometric passport.
Eligibility.
At present, European Economic Area, Andorran, Monegasque, San Marinese and Swiss citizens can use the PARAFE eGates, provided that they are aged 18 years or over and hold valid biometric passports. Minors aged 12-17 can also use the gates at certain arrival controls, but never on departure because the French authorities have strict rules about unaccompanied minors leaving the country.
Operation.
To use the PARAFE gates, the traveller must have a biometric passport from France and certain other countries (these ePassports have the biometric logo on the front cover). A computer in the gate scanner reads all the information contained in the chip inside the passport, while a camera takes a picture of the passenger from which biometric patterns are verified against those from the picture saved in the passport chip. The ePassport gate scanner reads all the information contained in the chip inside the passport and runs the data against numerous databases to determine if the traveller is a security risk, while a camera takes a picture of the traveller and an officer at a control station behind the gates checks that the image captured by the camera matches the one on the passport (facial recognition). Once the data verification and facial recognition process is complete, doors will automatically either open, signifying that the traveller is permitted to enter and/or exit the country, or remain closed and a stop icon illuminate, demonstrating that the traveller has failed the security checks and will personally meet with immigration officials.
Availability.
At present, PARAFE eGates are available at the following locations:
History.
The previous generation of the PARAFE eGates used fingerprint technology verify the identity of the passenger and was first introduced in 2010. This was phased out since it was considered "insufficiently intuitive" (which hand, which finger), a slower process and non-French citizens had to actively sign up at a French airport every 5 years to be able to use the eGates.
The first eGates were replaced in early 2017 for a pilot project of the facial recognition technology, which was extended to more airports and St Pancras station throughout the rest of 2017 and 2018. There are still some gates left that work with the fingerprint technology and new registrations are still accepted.
