What are the new checks?published at 13:36 BST
A new EU digital border system was introduced in October last year, changing the requirements for British citizens travelling to the Schengen area.
The system - known as Entry/Exit System or EES - replaces passport stamping with digitally recorded entries. Those travelling on a UK passport may be required to register biometric details like fingerprints and a photo, the UK Foreign Office explains.
The Port of Dover has said previously it is "working closely" with French border agency partners to "ensure a smooth introduction" for tourist passengers.
But after long delays heading into the bank holiday weekend - seen as a major test of the new system - French authorities suspended the extra checks today after the port escalated the "challenging situation".
As we reported earlier, French authorities had not yet switched on the fingerprint and photo machines, but still had to create profiles for travellers linked to the new system, contributing to delays.
