The registration number of every vehicle which enters and leaves Rosslare Europort will be instantly recorded under new technology.
Revenue is introducing an Automatic Number Plate Recognition (ANPR) system on a pilot basis at the busy Co Wexford hub.
The new technology will help Revenue officers quickly track and identify vehicles suspected of illegally carrying goods such as drugs or cigarettes.
A Revenue spokeswoman said: “Officers had to previously scroll through hours of CCTV footage if they wanted to track the registration details of a single vehicle. This new system will make this work more time-efficient.”
The new technology, which will be installed in coming months, will be used on Rosslare’s import and export channels.
Last week officers seized €439,000 in cash which had been concealed in the door panels of a car arriving at Rosslare from France.
In August six million contraband cigarettes with an estimated street value of €2.2m were discovered in a fruit and vegetable lorry.
Last July, a 25kg package of cannabis resin was found hidden in a petrol tank in a UK-registered car which had arrived at Rosslare from Cherbourg in France.
