Dublin Airport has introduced five new 3D security scanners which will allow for quicker security checks.
The C3 technology means passengers will no longer have to remove liquids or laptops from hand luggage, reducing security wait times.
Workers installing the state-of-the-art equipment have had to reinforce some of the old Terminal 1 floors to take the weight of the machines.
DAA Media Relations Manager Graeme McQueen has said normal rules still apply until all the machines are installed.
"Until all the scanners are in across both terminals, security rules will remain the same," he said.
"So people should prepare for security as normal; be ready to take your liquids out of your bags, be sure they're under 100 ml, be ready to take your laptops and electronics out as well.
"These new scanners will make a big difference when they come in.
"It's just going to take us a bit of time to get them all in, and once we have it will mean a big change for passengers," he added.
The rollout of new C3 security scanners at Dublin Airport continues apace. By mid-June, we'll have 5 scanners installed in our 2 terminals, including this new lane in T2.

Authorities have been testing the enhanced x-ray technology at the airport since 2002.
It means passengers can potentially bring whatever liquids they require without restriction on bottle size, as long as they are stored within cabin baggage.
Plans are also being made to upgrade the passenger security screening area at Cork Airport.
Similar machines are already being used at Shannon Airport.
The liquids rule has been in place since 2006 to guard against terrorism.
