The EU's new digital border system will require British travelers to be fingerprinted and face scanned on their first trip after the introduction of the innovations.
The system is expected to start functioning in the autumn of next year, the "Guardian" reported.
The Entry/Exit System (EES) will become operational on 6 October 2024.
Eurotunnel, which runs the car service between Folkestone and Calais, is testing technology where personal data will be collected at borders and entered into an EU-wide database.
Under the new system, travelers will have to consent to fingerprinting and facial imaging when they first arrive on the mainland. The data, including all denied-entry records, will then allow documents to be processed quickly, border officials said.
The system's originally planned rollout, which had been planned for this year, was delayed due to concerns it could disrupt travel to next summer's Paris Olympics.
The system is expected to cause significant delays at the start. The Port of Dover previously estimated the extra requirements were likely to add up to 10 minutes for a family of five in a vehicle on their first journey, compared to around 45-90 seconds previously.
Eurotunnel reports that the average time to process a car across the French border will increase from less than 60 seconds to 5-7 minutes. /BGNES
