The loan is the largest ever EIB support for transport-investment in the country.
Dublin Airport Authority spokesperson Paul O’Kane said: “In terms security, the investment we will be making with this money is an investment in baggage screening technology, which is required under new rules.
“That means that when your bag is checked in, it goes through a very specific screening process at the airport and that happens at all airports and we’ll be investing to upgrade that particular technology.”
