PARAFE

The gates use facial recognition technology to verify the user's identity against the data stored in the chip in their biometric passport.

At present, citizens of the following countries can use the PARAFE gates for both entering and exiting the Schengen area, provided that they are aged 18 years or over and hold valid biometric passports.

[12] 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).

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.

[12] 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.
